title: Introducing Experiments
description:
A look at where task is, where it's going and how we're going to get there.

Lately, Task has been growing extremely quickly and I've found myself thinking a
lot about the future of the project and how we continue to evolve and grow. I'm
not much of a writer, but I think one of the things we could do better is to
communicate these kinds of thoughts to the community. So, with that in mind,
this is the first (hopefully of many) blog posts talking about Task and what
we're up to.
<!--truncate-->
## :calendar: So, what have we been up to?
Over the past 12 months or so, [@andreynering] (Author and maintainer of the
project) and I ([@pd93]) have been working in our spare time to maintain and
improve v3 of Task and we've made some amazing progress. Here are just some of
the things we've released in that time:
- An official [extension for VS Code][vscode-task].
- Internal Tasks ([#818](https://github.com/go-task/task/pull/818)).
- Task aliases ([#879](https://github.com/go-task/task/pull/879)).
- Looping over tasks ([#1220](https://github.com/go-task/task/pull/1200)).
- A series of refactors to the core codebase to make it more maintainable and
extensible.
- Loads of bug fixes and improvements.
- An integration with [Crowdin][crowdin]. Work is in progress on making our docs
available in **7 new languages** (Special thanks to all our translators for
the huge help with this!).
- And much, much more! :sparkles:
We're also working on adding some really exciting and highly requested features
to Task such as having the ability to run remote Taskfiles
([#1317](https://github.com/go-task/task/issues/1317)).
None of this would have been possible without the [150 or so (and growing)
contributors][contributors] to the project, numerous sponsors and a passionate
community of users. Together we have more than doubled the number of GitHub
stars to over 8400 :star: since the beginning of 2022 and this continues to
accelerate. We can't thank you all enough for your help and support! :rocket:
[![Star History Chart](https://api.star-history.com/svg?repos=go-task/task&type=Date)](https://star-history.com/#go-task/task&Date)
## What's next? :thinking:
It's extremely motivating to see so many people using and loving Task. However,
in this time we've also seen an increase in the number of issues and feature
requests. In particular, issues that require some kind of breaking change to
Task. This isn't a bad thing, but as we grow we need to be more responsible
about how we address these changes in a way that ensures stability and
compatibility for existing users and their Taskfiles.
At this point you're probably thinking something like:
> "But you use [semantic versioning][semver] - Just release a new major version
> with your breaking changes."
And you'd be right... sort of. In theory, this sounds great, but the reality is
that we don't have the time to commit to a major overhaul of Task in one big
bang release. This would require a colossal amount of time and coordination and
with full time jobs and personal lives to tend to, this is a difficult
commitment to make. Smaller, more frequent major releases are also a significant
inconvenience for users as they have to constantly keep up-to-date with our
breaking changes. Fortunately, there is a better way.
## What's going to change? :monocle:
Going forwards, breaking changes will be allowed into _minor_ versions of Task
as "experimental features". To access these features users will need opt-in by
enabling feature flags. This will allow us to release new features slowly and
gather feedback from the community before making them the default behavior in a
future major release.
To prepare users for the next major release, we will maintain a list of
[deprecated features][deprecations] and [experiments][experiments] on our docs
website and publish information on how to migrate to the new behavior.
You can read the [full breaking change proposal][breaking-change-proposal] and
view all the [current experiments and their status][experiments-project] on
GitHub including the [Gentle Force][gentle-force-experiment] and [Remote
Taskfiles][remote-taskfiles-experiment] experiments.
## What will happen to v2/v3 features?
v2 has been [officially deprecated][deprecate-version-2-schema]. If you're still
using a Taskfile with `version: "2"` at the top we _strongly recommend_ that you
upgrade as soon as possible. Removing v2 will allow us to tidy up the codebase
and focus on new functionality instead.
When v4 is released, we will continue to support v3 for a period of time (bug
fixes etc). However, since we are moving from a backward-compatibility model to
a forwards-compatibility model, **v4 itself will not be backwards compatible
with v3**.
## v4 When? :eyes:
:man_shrugging: When it's ready.
In all seriousness, we don't have a timeline for this yet. We'll be working on
the most serious deficiencies of the v3 API first and regularly evaluating the
state of the project. When we feel its in a good, stable place and we have a
clear upgrade path for users and a number of stable experiments, we'll start to
think about v4.
## :wave: Final thoughts
Task is growing fast and we're excited to see where it goes next. We hope that
the steps we're taking to improve the project and our process will help us to
continue to grow. As always, if you have any questions or feedback, we encourage
you to comment on or open [issues][issues] and [discussions][discussions] on
GitHub. Alternatively, you can join us on [Discord][discord].
I plan to write more of these blog posts in the future on a variety of
Task-related topics, so make sure to check in occasionally and see what we're up
to!

- Taskfile errors (100-199)
- Task errors (200-299)
A full list of the exit codes and their descriptions can be found below:

[`errors/errors.go`](https://github.com/go-task/task/blob/main/errors/errors.go).
:::info
When Task is run with the `-x`/`--exit-code` flag, the exit code of any failed
commands will be passed through to the user instead.
:::
## JSON Output
When using the `--json` flag in combination with either the `--list` or
`--list-all` flags, the output will be a JSON object with the following

:::
:::info
In a variables map, variables defined later may reference variables defined
earlier (declaration order is respected):

:::
### Task
| Attribute | Type | Default | Description |
| --------------- | ---------------------------------- | ----------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `cmds` | [`[]Command`](#command) | | A list of shell commands to be executed. |
| `deps` | [`[]Dependency`](#dependency) | | A list of dependencies of this task. Tasks defined here will run in parallel before this task. |
| `label` | `string` | | Overrides the name of the task in the output when a task is run. Supports variables. |
| `desc` | `string` | | A short description of the task. This is displayed when calling `task --list`. |
| `prompt` | `string` | | A prompt that will be presented before a task is run. Declining will cancel running the current and any subsequent tasks. |
| `summary` | `string` | | A longer description of the task. This is displayed when calling `task --summary [task]`. |
| `aliases` | `[]string` | | A list of alternative names by which the task can be called. |
| `sources` | `[]string` | | A list of sources to check before running this task. Relevant for `checksum` and `timestamp` methods. Can be file paths or star globs. |
| `generates` | `[]string` | | A list of files meant to be generated by this task. Relevant for `timestamp` method. Can be file paths or star globs. |
| `status` | `[]string` | | A list of commands to check if this task should run. The task is skipped otherwise. This overrides `method`, `sources` and `generates`. |
| `preconditions` | [`[]Precondition`](#precondition) | | A list of commands to check if this task should run. If a condition is not met, the task will error. |
| `requires` | [`Requires`](#requires) | | A list of required variables which should be set if this task is to run, if any variables listed are unset the task will error and not run. |

| `interactive` | `bool` | `false` | Tells task that the command is interactive. |
| `internal` | `bool` | `false` | Stops a task from being callable on the command line. It will also be omitted from the output when used with `--list`. |
| `method` | `string` | `checksum` | Defines which method is used to check the task is up-to-date. `timestamp` will compare the timestamp of the sources and generates files. `checksum` will check the checksum (You probably want to ignore the .task folder in your .gitignore file). `none` skips any validation and always run the task. |
| `prefix` | `string` | | Defines a string to prefix the output of tasks running in parallel. Only used when the output mode is `prefixed`. |
| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing commands. |

foobar:
- echo "foo"
- echo "bar"
baz:
cmd: echo "baz"

| `for` | [`For`](#for) | | Runs the command once for each given value. |
| `silent` | `bool` | `false` | Skips some output for this command. Note that STDOUT and STDERR of the commands will still be redirected. |
| `vars` | [`map[string]Variable`](#variable) | | Optional additional variables to be passed to the referenced task. Only relevant when setting `task` instead of `cmd`. |
| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing the command. |
| `defer` | `string` | | Alternative to `cmd`, but schedules the command to be executed at the end of this task instead of immediately. This cannot be used together with `cmd`. |
| `platforms` | `[]string` | All platforms | Specifies which platforms the command should be run on. [Valid GOOS and GOARCH values allowed](https://github.com/golang/go/blob/main/src/go/build/syslist.go). Command will be skipped otherwise. |
| `set` | `[]string` | | Specify options for the [`set` builtin](https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html). |
| `shopt` | `[]string` | | Specify option for the [`shopt` builtin](https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html). |
:::info
If given as a a string, the value will be assigned to `cmd`:
```yaml
tasks:
foo:
cmds:
- echo "foo"
- echo "bar"
```
:::
#### Dependency
| Attribute | Type | Default | Description |
| --------- | ---------------------------------- | ------- | ---------------------------------------------------------------------------------------------------------------- |
| `task` | `string` | | The task to be execute as a dependency. |
| `vars` | [`map[string]Variable`](#variable) | | Optional additional variables to be passed to this task. |
| `silent` | `bool` | `false` | Hides task name and command from output. The command's output will still be redirected to `STDOUT` and `STDERR`. |
:::tip
If you don't want to set additional variables, it's enough to declare the
dependency as a list of strings (they will be assigned to `task`):
```yaml
tasks:
foo:
deps: [foo, bar]
```
:::
#### For
The `for` parameter can be defined as a string, a list of strings or a map. If
it is defined as a string, you can give it any of the following values:
- `source` - Will run the command for each source file defined on the task.
(Glob patterns will be resolved, so `*.go` will run for every Go file that
matches).
If it is defined as a list of strings, the command will be run for each value.
Finally, the `for` parameter can be defined as a map when you want to use a
variable to define the values to loop over:
| Attribute | Type | Default | Description |
| --------- | -------- | ---------------- | -------------------------------------------- |
| `var` | `string` | | The name of the variable to use as an input. |
| `split` | `string` | (any whitespace) | What string the variable should be split on. |
| `as` | `string` | `ITEM` | The name of the iterator variable. |
#### Precondition
| Attribute | Type | Default | Description |
| --------- | -------- | ------- | ------------------------------------------------------------------------------------------------------------ |
| `sh` | `string` | | Command to be executed. If a non-zero exit code is returned, the task errors without executing its commands. |
| `msg` | `string` | | Optional message to print if the precondition isn't met. |
:::tip
If you don't want to set a different message, you can declare a precondition
like this and the value will be assigned to `sh`:
```yaml
tasks:
foo:
precondition: test -f Taskfile.yml
```
:::
#### Requires
| Attribute | Type | Default | Description |
| --------- | ---------- | ------- | -------------------------------------------------------------------------------------------------- |
| `vars` | `[]string` | | List of variable or environment variable names that must be set if this task is to execute and run |

@andarto, #1309 by @andreynering).
- Fix bug on `--status` flag. Running this flag should not have side-effects: it
should not update the checksum on `.task`, only report its status (#1305,
#1307 by @visciang, #1313 by @andreynering).
## v3.28.0 - 2023-07-24

- Added an `--experiments` flag to allow you to see which experiments are
enabled (#1242 by @pd93).
- Added ability to specify which variables are required in a task (#1203, #1204
by @benc-uk).
## v3.26.0 - 2023-06-10
- Only rewrite checksum files in `.task` if the checksum has changed (#1185,
#1194 by @deviantintegral).
- Added [experiments documentation](https://taskfile.dev/experiments) to the
website (#1198 by @pd93).
- Deprecated `version: 2` schema. This will be removed in the next major release
(#1197, #1198, #1199 by @pd93).
- Added a new `prompt:` prop to set a warning prompt to be shown before running
a potential dangurous task (#100, #1163 by @MaxCheetham,
[Documentation](https://taskfile.dev/usage/#warning-prompts)).
- Added support for single command task syntax. With this change, it's now
possible to declare just `cmd:` in a task, avoiding the more complex
`cmds: []` when you have only a single command for that task (#1130, #1131 by
@timdp).
## v3.25.0 - 2023-05-22
- Support `silent:` when calling another tasks (#680, #1142 by @danquah).

## v3.23.0 - 2023-03-26
Task now has an
[official extension for Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=task.vscode-task)
contributed by @pd93! :tada: The extension is maintained in a
[new repository](https://github.com/go-task/vscode-task) under the `go-task`
organization. We're looking to gather feedback from the community so please give
it a go and let us know what you think via a
[discussion](https://github.com/go-task/vscode-task/discussions),
[issue](https://github.com/go-task/vscode-task/issues) or on our
[Discord](https://discord.gg/6TY36E39UK)!
> **NOTE:** The extension _requires_ v3.23.0 to be installed in order to work.
- The website was integrated with
[Crowdin](https://crowdin.com/project/taskfile) to allow the community to
contribute with translations! [Chinese](https://taskfile.dev/zh-Hans/) is the
first language available (#1057, #1058 by @misitebao).
- Added task location data to the `--json` flag output (#1056 by @pd93)

anywhere in your system!
([Documentation](https://taskfile.dev/usage/#running-a-global-taskfile), #1029
by @andreynering).

instruct Task to only print a command output if it returned with a non-zero
exit code (#664, #1022 by @jaedle).
- Fixed bug where `.task/checksum` file was sometimes not being created when
task also declares a `status:` (#840, #1035 by @harelwa, #1037 by @pd93).

mode (#976, #977 by @aminya).
- Performance optimizations were made for large Taskfiles (#982 by @pd93).
- Add ability to configure options for the
[`set`](https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html)
and
[`shopt`](https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html)
builtins (#908, #929 by @pd93,
[Documentation](http://taskfile.dev/usage/#set-and-shopt)).
- Add new `platforms:` attribute to `task` and `cmd`, so it's now possible to
choose in which platforms that given task or command will be run on. Possible
values are operating system (GOOS), architecture (GOARCH) or a combination of
the two. Example: `platforms: [linux]`, `platforms: [amd64]` or
`platforms: [linux/amd64]`. Other platforms will be skipped (#978, #980 by

editors and add room to other possible integrations. This is basic for now,
but we plan to add more info in the near future (#936 by @davidalpert, #764).
## v3.19.0 - 2022-12-05
- Installation via npm now supports [pnpm](https://pnpm.io/) as well
([go-task/go-npm#2](https://github.com/go-task/go-npm/issues/2),
[go-task/go-npm#3](https://github.com/go-task/go-npm/pull/3)).
- It's now possible to run Taskfiles from subdirectories! A new

will be completed by the completion scripts (#919).
- Tasks in the root Taskfile will now be displayed first in
`--list`/`--list-all` output (#806, #890).

- Fix error when using variable in `env:` introduced in the previous release
(#858, #866).

- Add new special variables `ROOT_DIR` and `TASKFILE_DIR`. This was a highly
requested feature (#215, #857,
[Documentation](https://taskfile.dev/api/#special-variables)).
- Follow symlinks on `sources` (#826, #831).
- Improvements and fixes to Bash completion (#835, #844).

`TASK_COLOR_MAGENTA` and `TASK_COLOR_RED` (#568, #792).
- Fixed bug when using the `output: group` mode where STDOUT and STDERR were
being print in separated blocks instead of in the right order (#779).
- Starting on this release, ARM architecture binaries are been released to Snap
as well (#795).
- i386 binaries won't be available anymore on Snap because Ubuntu removed the
support for this architecture.
- Upgrade mvdan.cc/sh, which fixes a bug with associative arrays (#785,
[mvdan/sh#884](https://github.com/mvdan/sh/issues/884),

only removing the final `\n` but not `\r\n` (#717).
## v3.12.0 - 2022-03-31
- The `--list` and `--list-all` flags can now be combined with the `--silent`
flag to print the task names only, without their description (#691).

with the `defer:` keyword
([Documentation](https://taskfile.dev/#/usage?id=doing-task-cleanup-with-defer),
#475, #626).
- Remove long deprecated and undocumented `$` variable prefix and `^` command
prefix (#642, #644, #645).

- New magic variables are now available when using `status:`: `.TIMESTAMP` which
contains the greatest modification date from the files listed in `sources:`,
and `.CHECKSUM`, which contains a checksum of all files listed in `status:`.
This is useful for manual checking when using external, or even remote,
artifacts when using `status:` (#216).
- We're now using [slim-sprig](https://github.com/go-task/slim-sprig) instead of
[sprig](https://github.com/Masterminds/sprig), which allowed a file size

# Contributing
Contributions to Task are very welcome, but we ask that you read this document
before submitting a PR.
:::note
This document applies to the core [Task][task] repository _and_ [Task for Visual
Studio Code][vscode-task].
:::
## Before you start
- **Check existing work** - Is there an existing PR? Are there issues discussing
the feature/change you want to make? Please make sure you consider/address
these discussions in your work.
- **Backwards compatibility** - Will your change break existing Taskfiles? It is
much more likely that your change will merged if it backwards compatible. Is
there an approach you can take that maintains this compatibility? If not,
consider opening an issue first so that API changes can be discussed before
you invest your time into a PR.
- **Experiments** - If there is no way to make your change backward compatible
then there is a procedure to introduce breaking changes into minor versions.
We call these "[experiments][experiments]". If you're intending to work on an
experiment, then please read the [experiments workflow][experiments-workflow]
document carefully and submit a proposal first.
## 1. Setup
- **Go** - Task is written in [Go][go]. We always support the latest two major
Go versions, so make sure your version is recent enough.
- **Node.js** - [Node.js][nodejs] is used to host Task's documentation server
and is required if you want to run this server locally. It is also required if
you want to contribute to the Visual Studio Code extension.
- **Yarn** - [Yarn][yarn] is the Node.js package manager used by Task.
## 2. Making changes
- **Code style** - Try to maintain the existing code style where possible. Go
code should be formatted by [`gofumpt`][gofumpt] and linted using
[`golangci-lint`][golangci-lint]. Any Markdown or TypeScript files should be
formatted and linted by [Prettier][prettier]. This style is enforced by our CI
to ensure that we have a consistent style across the project. You can use the
`task lint` command to lint the code locally and the `task lint:fix` command
to automatically fix any issues that are found.
- **Documentation** - Ensure that you add/update any relevant documentation. See
the [updating documentation](#updating-documentation) section below.
- **Tests** - Ensure that you add/update any relevant tests and that all tests
are passing before submitting the PR. See the [writing tests](#writing-tests)
section below.
### Running your changes
To run Task with working changes, you can use `go run ./cmd/task`. To run a
development build of task against a test Taskfile in `testdata`, you can use
`go run ./cmd/task --dir ./testdata/<my_test_dir> <task_name>`.
To run Task for Visual Studio Code, you can open the project in VSCode and hit
F5 (or whatever you debug keybind is set to). This will open a new VSCode window
with the extension running. Debugging this way is recommended as it will allow
you to set breakpoints and step through the code. Otherwise, you can run
`task package` which will generate a `.vsix` file that can be used to manually
install the extension.
### Updating documentation
Task uses [Docusaurus][docusaurus] to host a documentation server. The code for
this is located in the core Task repository. This can be setup and run locally
by using `task docs` (requires `nodejs` & `yarn`). All content is written in
Markdown and is located in the `docs/docs` directory. All Markdown documents
should have an 80 character line wrap limit (enforced by Prettier).
When making a change, consider whether a change to the [Usage
Guide](/usage) is necessary. This document contains descriptions and
examples of how to use Task features. If you're adding a new feature, try to
find an appropriate place to add a new section. If you're updating an existing
feature, ensure that the documentation and any examples are up-to-date. Ensure
that any examples follow the [Taskfile Styleguide](/styleguide).
If you added a new field, command or flag, ensure that you add it to the
[API Reference](/api). New fields also need to be added to the
[JSON Schema][json-schema]. The descriptions for fields in the API reference and
the schema should match.
### Writing tests
A lot of Task's tests are held in the `task_test.go` file in the project root
and this is where you'll most likely want to add new ones too. Most of these
tests also have a subdirectory in the `testdata` directory where any
Taskfiles/data required to run the tests are stored.
When making a changes, consider whether new tests are required. These tests
should ensure that the functionality you are adding will continue to work in the
future. Existing tests may also need updating if you have changed Task's
behavior.
You may also consider adding unit tests for any new functions you have added.
The unit tests should follow the Go convention of being location in a file named
`*_test.go` in the same package as the code being tested.
## 3. Committing your code
Try to write meaningful commit messages and avoid having too many commits on the
PR. Most PRs should likely have a single commit (although for bigger PRs it may
be reasonable to split it in a few). Git squash and rebase is your friend!
If you're not sure how to format your commit message, check out [Conventional
Commits][conventional-commits]. This style is not enforced, but it is a good way
to make your commit messages more readable and consistent.
## 4. Submitting a PR
- **Describe your changes** - Ensure that you provide a comprehensive
description of your changes.
- **Issue/PR links** - Link any previous work such as related issues or PRs.
Please describe how your changes differ to/extend this work.
- **Examples** - Add any examples or screenshots that you think are useful to
demonstrate the effect of your changes.
- **Draft PRs** - If your changes are incomplete, but you would like to discuss
them, open the PR as a draft and add a comment to start a discussion. Using
comments rather than the PR description allows the description to be updated
later while preserving any discussions.
## FAQ
> I want to contribute, where do I start?
Take a look at the list of [open issues for Task][task-open-issues] or [Task for
Visual Studio Code][vscode-task-open-issues]. We have a [good first

# Deprecations
As Task evolves, it occasionally outgrows some of its functionality. This can be
because they are no longer useful, because another feature has replaced it or
because of a change in the way that Task works internally.
When this happens, we mark the functionality as deprecated. This means that it
will be removed in a future version of Task. This functionality will continue to
work until that time, but we strongly recommend that you do not implement this
functionality in new Taskfiles and make a plan to migrate away from it as soon
as possible.
You can view a full list of active deprecations in the "Deprecations" section of
the sidebar.

# Version 2 Schema (#1197)
:::warning
This deprecation breaks the following functionality:
- Any Taskfiles that use the version 2 schema
- `Taskvar.yml` files
:::
The Taskfile version 2 schema was introduced in March 2018 and replaced by
version 3 in August 2019. In May 2023 [we published a deprecation
notice][deprecation-notice] for the version 2 schema on the basis that the vast
majority of users had already upgraded to version 3 and removing support for
version 2 would allow us to tidy up the codebase and focus on new functionality
instead.
In December 2023, the final version of Task that supports the version 2 schema
([v3.33.0][v3.33.0]) was published and all legacy code was removed from Task's
main branch. To use a more recent version of Task, you will need to ensure that
your Taskfile uses the version 3 schema instead. A list of changes between
version 2 and version 3 are available in the [Task v3 Release Notes][v3.0.0].

# Any Variables (#1415)
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
Currently, Task only supports string variables. This experiment allows you to
specify and use the following variable types:
- `string`
- `bool`
- `int`
- `float`
- `array`
- `map`
This allows you to have a lot more flexibility in how you use variables in
Task's templating engine. There are two active proposals for this experiment.
Click on the tabs below to switch between them.
<Tabs defaultValue="1" queryString="proposal"
values={[
{label: 'Proposal 1', value: '1'},
{label: 'Proposal 2', value: '2'}
]}>
<TabItem value="1">
:::warning
This experiment proposal breaks the following functionality:
- Dynamically defined variables (using the `sh` keyword)
:::
:::info
To enable this experiment, set the environment variable:
`TASK_X_ANY_VARIABLES=1`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
## Maps
This proposal removes support for the `sh` keyword in favour of a new syntax for
dynamically defined variables, This allows you to define a map directly as you
would for any other type:
```yaml
version: 3
tasks:
foo:
vars:
FOO: {a: 1, b: 2, c: 3} # <-- Directly defined map on the `FOO` key
cmds:
- 'echo {{.FOO.a}}'
```
## Migration
Taskfiles with dynamically defined variables via the `sh` subkey will no longer
work with this experiment enabled. In order to keep using dynamically defined
variables, you will need to migrate your Taskfile to use the new syntax.
Previously, you might have defined a dynamic variable like this:
```yaml
version: 3
tasks:
foo:
vars:
CALCULATED_VAR:
sh: 'echo hello'
cmds:
- 'echo {{.CALCULATED_VAR}}'
```
With this experiment enabled, you will need to remove the `sh` subkey and define
your command as a string that begins with a `$`. This will instruct Task to
interpret the string as a command instead of a literal value and the variable
will be populated with the output of the command. For example:
```yaml
version: 3
tasks:
foo:
vars:
CALCULATED_VAR: '$echo hello'
cmds:
- 'echo {{.CALCULATED_VAR}}'
```
If your current Taskfile contains a string variable that begins with a `$`, you
will now need to escape the `$` with a backslash (`\`) to stop Task from
executing it as a command.
</TabItem>
<TabItem value="2">
:::info
To enable this experiment, set the environment variable:
`TASK_X_ANY_VARIABLES=2`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
## Maps
This proposal maintains backwards-compatibility and the `sh` subkey and adds
another new `map` subkey for defining map variables:
```yaml
version: 3
tasks:
foo:
vars:
FOO:
map: {a: 1, b: 2, c: 3} # <-- Defined using the `map' subkey instead of directly on 'FOO'
BAR: true # <-- Other types of variables are still defined directly on the key
BAZ:
sh: 'echo Hello Task' # <-- The `sh` subkey is still supported
cmds:
- 'echo {{.FOO.a}}'
```
## Parsing JSON and YAML
In addition to the new `map` keyword, this proposal also adds support for the
`json` and `yaml` keywords for parsing JSON and YAML strings into real
objects/arrays. This is similar to the `fromJSON` template function, but means
that you only have to parse the JSON/YAML once when you declare the variable,
instead of every time you want to access a value.
Before:
```yaml
version: 3
tasks:
foo:
vars:
FOO: '{"a": 1, "b": 2, "c": 3}' # <-- JSON string
cmds:
- 'echo {{(fromJSON .FOO).a}}' # <-- Parse JSON string every time you want to access a value
- 'echo {{(fromJSON .FOO).b}}'
```
After:
```yaml
version: 3
tasks:
foo:
vars:
FOO:
json: '{"a": 1, "b": 2, "c": 3}' # <-- JSON string parsed once
cmds:
- 'echo {{.FOO.a}}' # <-- Access values directly
- 'echo {{.FOO.b}}'
```
## Variables by reference
Lastly, this proposal adds support for defining and passing variables by
reference. This is really important now that variables can be types other than a
string. Previously, to send a variable from one task to another, you would have
to use the templating system to pass it:
```yaml
version: 3
tasks:
foo:
vars:
FOO: [A, B, C] # <-- FOO is defined as an array
cmds:
- task: bar
vars:
FOO: '{{.FOO}}' # <-- FOO gets converted to a string when passed to bar
bar:
cmds:
- 'echo {{index .FOO 0}}' # <-- FOO is a string so the task outputs '91' which is the ASCII code for '[' instead of the expected 'A'
```
Unfortunately, this results in the value always being passed as a string as this
is the output type of the templater and operations on the passed variable may
not behave as expected. With this proposal, you can now pass variables by
reference using the `ref` subkey:
```yaml
version: 3
tasks:
foo:
vars:
FOO: [A, B, C] # <-- FOO is defined as an array
cmds:
- task: bar
vars:
FOO:
ref: FOO # <-- FOO gets passed by reference to bar and maintains its type
bar:
cmds:
- 'echo {{index .FOO 0}}' # <-- FOO is still a map so the task outputs 'A' as expected
```
This means that the type of the variable is maintained when it is passed to
another Task. This also works the same way when calling `deps` and when defining
a variable and can be used in any combination:
```yaml
version: 3
tasks:
foo:
vars:
FOO: [A, B, C] # <-- FOO is defined as an array
BAR:
ref: FOO # <-- BAR is defined as a reference to FOO
deps:
- task: bar
vars:
BAR:
ref: BAR # <-- BAR gets passed by reference to bar and maintains its type
bar:
cmds:
- 'echo {{index .BAR 0}}' # <-- BAR still refers to FOO so the task outputs 'A'
```
</TabItem></Tabs>
---
## Common to both proposals
Both proposals add support for all other variable types by directly defining
them in the Taskfile. For example:
### Evaluating booleans
```yaml
version: 3
tasks:
foo:
vars:
BOOL: false
cmds:
- '{{if .BOOL}}echo foo{{end}}'
```
### Arithmetic
```yaml
version: 3
tasks:
foo:
vars:
INT: 10
FLOAT: 3.14159
cmds:
- 'echo {{add .INT .FLOAT}}'
```
### Ranging
```yaml
version: 3
tasks:
foo:
vars:
ARRAY: [1, 2, 3]
cmds:
- 'echo {{range .ARRAY}}{{.}}{{end}}'
```
There are many more templating functions which can be used with the new types of
variables. For a full list, see the [slim-sprig][slim-sprig] documentation.
## Looping over variables
Previously, you would have to use a delimiter separated string to loop over an
arbitrary list of items in a variable and split them by using the `split` subkey
to specify the delimiter:
```yaml
version: 3
tasks:
foo:
vars:
LIST: 'foo,bar,baz'
cmds:
- for:
var: LIST
split: ','
cmd: echo {{.ITEM}}
```
Both of these proposals add support for looping over "collection-type" variables
using the `for` keyword, so now you are able to loop over a map/array variable
directly:
```yaml
version: 3
tasks:
foo:
vars:
LIST: [foo, bar, baz]
cmds:
- for:
var: LIST
cmd: echo {{.ITEM}}
```
When looping over a map we also make an additional `{{.KEY}}` variable availabe
that holds the string value of the map key. Remember that maps are unordered, so
the order in which the items are looped over is random.

# Experiments
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
In order to allow Task to evolve quickly, we sometimes roll out breaking changes
to minor versions behind experimental flags. This allows us to gather feedback
on breaking changes before committing to a major release. This process can also
be used to gather feedback on important non-breaking features before their
design is completed. This document describes the
[experiment workflow](#workflow) and how you can get involved.
You can view the full list of active experiments in the sidebar submenu to the
left of the page and click on each one to find out more about it.
## Enabling Experiments
Task uses environment variables to detect whether or not an experiment is
enabled. All of the experiment variables will begin with the same `TASK_X_`
prefix followed by the name of the experiment. You can find the exact name for
each experiment on their respective pages in the sidebar. If the variable is set
`=1` then it will be enabled. Some experiments may have multiple proposals, in
which case, you will need to set the variable equal to the number of the
proposal that you want to enable (`=2`, `=3` etc).
There are three main ways to set the environment variables for an experiment.
Which method you use depends on how you intend to use the experiment:
1. Prefixing your task commands with the relevant environment variable(s). For
example, `TASK_X_{FEATURE}=1 task {my-task}`. This is intended for one-off
invocations of Task to test out experimental features.
1. Adding the relevant environment variable(s) in your "dotfiles" (e.g.
`.bashrc`, `.zshrc` etc.). This will permanently enable experimental features
for your personal environment.
```shell title="~/.bashrc"
export TASK_X_FEATURE=1
```
1. Creating a `.env` file in the same directory as your root Taskfile that
contains the relevant environment variable(s). This allows you to enable an
experimental feature at a project level. If you commit the `.env` file to
source control then other users of your project will also have these
experiments enabled.
```shell title=".env"
TASK_X_FEATURE=1
```
## Workflow
Experiments are a way for us to test out new features in Task before committing
to them in a major release. Because this concept is built around the idea of
feedback from our community, we have built a workflow for the process of
introducing these changes. This ensures that experiments are given the attention
and time that they need and that we are getting the best possible results out of
them.
The sections below describe the various stages that an experiment must go
through from its proposal all the way to being released in a major version of
Task.
### 1. Proposal
All experimental features start with a proposal in the form of a GitHub issue.
If the maintainers decide that an issue has enough support and is a breaking
change or is complex/controversial enough to require user feedback, then the
issue will be marked with the `experiment: proposal` label. At this point, the
issue becomes a proposal and a period of consultation begins. During this
period, we request that users provide feedback on the proposal and how it might
effect their use of Task. It is up to the discretion of the maintainers to
decide how long this period lasts.
### 2. Draft
Once a proposal's consultation ends, a contributor may pick up the work and
begin the initial implementation. Once a PR is opened, the maintainers will
ensure that it meets the requirements for an experimental feature (i.e. flags
are in the right format etc) and merge the feature. Once this code is released,
the status will be updated via the `experiment: draft` label. This indicates
that an implementation is now available for use in a release and the experiment
is open for feedback.
:::note
During the draft period, major changes to the implementation may be made based
on the feedback received from users. There are _no stability guarantees_ and
experimental features may be abandoned _at any time_.
:::
### 3. Candidate
Once an acceptable level of consensus has been reached by the community and
feedback/changes are less frequent/significant, the status may be updated via
the `experiment: candidate` label. This indicates that a proposal is _likely_ to
accepted and will enter a period for final comments and minor changes.
### 4. Stable
Once a suitable amount of time has passed with no changes or feedback, an
experiment will be given the `experiment: stable` label. At this point, the
functionality will be treated like any other feature in Task and any changes
_must_ be backward compatible. This allows users to migrate to the new
functionality without having to worry about anything breaking in future
releases. This provides the best experience for users migrating to a new major
version.
### 5. Released
When making a new major release of Task, all experiments marked as
`experiment: stable` will move to `experiment: released` and their behaviors
will become the new default in Task. Experiments in an earlier stage (i.e. not
stable) cannot be released and so will continue to be experiments in the new
version.
### Abandoned / Superseded
If an experiment is unsuccessful at any point then it will be given the
`experiment: abandoned` or `experiment: superseded` labels depending on which is
more suitable. These experiments will be removed from Task.

# Gentle Force (#1200)
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
:::warning
This experiment breaks the following functionality:
- The `--force` flag
:::
:::info
To enable this experiment, set the environment variable:
`TASK_X_GENTLE_FORCE=1`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
The `--force` flag currently forces _all_ tasks to run regardless of the status
checks. This can be useful, but we have found that most of the time users only
expect the direct task they are calling to be forced and _not_ all of its
dependant tasks.
This experiment changes the `--force` flag to only force the directly called
task. All dependant tasks will have their statuses checked as normal and will
only run if Task considers them to be out of date. A new `--force-all` flag will
also be added to maintain the current behavior for users that need this
functionality.
If you want to migrate, but continue to force all dependant tasks to run, you
should replace all uses of the `--force` flag with `--force-all`. Alternatively,
if you want to adopt the new behavior, you can continue to use the `--force`
flag as you do now!

# Remote Taskfiles (#1317)
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
:::info
To enable this experiment, set the environment variable:
`TASK_X_REMOTE_TASKFILES=1`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
This experiment allows you to specify a remote Taskfile URL when including a
Taskfile. For example:
```yaml
version: '3'
includes:
my-remote-namespace: https://raw.githubusercontent.com/my-org/my-repo/main/Taskfile.yml
```
This works exactly the same way that including a local file does. Any tasks in
the remote Taskfile will be available to run from your main Taskfile via the
namespace `my-remote-namespace`. For example, if the remote file contains the
following:
```yaml
version: '3'
tasks:
hello:
silent: true
cmds:
- echo "Hello from the remote Taskfile!"
```
and you run `task my-remote-namespace:hello`, it will print the text: "Hello
from the remote Taskfile!" to your console.
## Security
Running commands from sources that you do not control is always a potential
security risk. For this reason, we have added some checks when using remote
Taskfiles:
1. When running a task from a remote Taskfile for the first time, Task will
print a warning to the console asking you to check that you are sure that you
trust the source of the Taskfile. If you do not accept the prompt, then Task
will exit with code `104` (not trusted) and nothing will run. If you accept
the prompt, the remote Taskfile will run and further calls to the remote
Taskfile will not prompt you again.
2. Whenever you run a remote Taskfile, Task will create and store a checksum of
the file that you are running. If the checksum changes, then Task will print
another warning to the console to inform you that the contents of the remote
file has changed. If you do not accept the prompt, then Task will exit with
code `104` (not trusted) and nothing will run. If you accept the prompt, the
checksum will be updated and the remote Taskfile will run.
Sometimes you need to run Task in an environment that does not have an
interactive terminal, so you are not able to accept a prompt. In these cases you
are able to tell task to accept these prompts automatically by using the `--yes`
flag. Before enabling this flag, you should:
1. Be sure that you trust the source and contents of the remote Taskfile.
2. Consider using a pinned version of the remote Taskfile (e.g. A link
containing a commit hash) to prevent Task from automatically accepting a
prompt that says a remote Taskfile has changed.
Task currently supports both `http` and `https` URLs. However, the `http`
requests will not execute by default unless you run the task with the
`--insecure` flag. This is to protect you from accidentally running a remote
Taskfile that is via an unencrypted connection. Sources that are not protected
by TLS are vulnerable to [man-in-the-middle attacks][man-in-the-middle-attacks]
and should be avoided unless you know what you are doing.
## Caching & Running Offline
Whenever you run a remote Taskfile, the latest copy will be downloaded from the
internet and cached locally. If for whatever reason, you lose access to the
internet, you will still be able to run your tasks by specifying the `--offline`
flag. This will tell Task to use the latest cached version of the file instead
of trying to download it. You are able to use the `--download` flag to update
the cached version of the remote files without running any tasks.
By default, Task will timeout requests to download remote files after 10 seconds
and look for a cached copy instead. This timeout can be configured by setting
the `--timeout` flag and specifying a duration. For example, `--timeout 5s` will
set the timeout to 5 seconds.

# FAQ
This page contains a list of frequently asked questions about Task.
## Why won't my task update my shell environment?
This is a limitation of how shells work. Task runs as a subprocess of your
current shell, so it can't change the environment of the shell that started it.
This limitation is shared by other task runners and build tools too.
A common way to work around this is to create a task that will generate output
that can be parsed by your shell. For example, to set an environment variable on
your shell you can write a task like this:
```yaml
my-shell-env:
cmds:
- echo "export FOO=foo"
- echo "export BAR=bar"
```
Now run `eval $(task my-shell-env)` and the variables `$FOO` and `$BAR` will be
available in your shell.
## I can't reuse my shell in a task's commands
Task runs each command as a separate shell process, so something you do in one
command won't effect any future commands. For example, this won't work:
```yaml
version: '3'
tasks:
foo:
cmds:
- a=foo
- echo $a
# outputs ""
```
To work around this you can either use a multiline command:
```yaml
version: '3'
tasks:
foo:
cmds:
- |
a=foo
echo $a
# outputs "foo"
```
Or for more complex multi-line commands it is recommended to move your code into
a separate file and call that instead:
```yaml
version: '3'
tasks:
foo:
cmds:
- ./foo-printer.bash
```
```shell
#!/bin/bash
a=foo
echo $a
```
## 'x' builtin command doesn't work on Windows
The default shell on Windows (`cmd` and `powershell`) do not have commands like
`rm` and `cp` available as builtins. This means that these commands won't work.
If you want to make your Taskfile fully cross-platform, you'll need to work
around this limitation using one of the following methods:
- Use the `{{OS}}` function to run an OS-specific script.
- Use something like `{{if eq OS "windows"}}powershell {{end}}<my_cmd>` to
detect windows and run the command in Powershell directly.
- Use a shell on Windows that supports these commands as builtins, such as [Git
Bash][git-bash] or [WSL][wsl].
We want to make improvements to this part of Task and the issues below track
this work. Constructive comments and contributions are very welcome!

# Installation
Task offers many installation methods. Check out the available methods below.
## Package Managers
### Homebrew
If you're on macOS or Linux and have [Homebrew][homebrew] installed, getting
Task is as simple as running:
```shell
brew install go-task/tap/go-task
```
The above Formula is
[maintained by ourselves](https://github.com/go-task/homebrew-tap/blob/main/Formula/go-task.rb).
Recently, Task was also made available
[on the official Homebrew repository](https://formulae.brew.sh/formula/go-task),
so you also have that option if you prefer:
```shell
brew install go-task
```
### pkgx
If you're on macOS or Linux and have [pkgx](https://pkgx.sh/) installed, getting Task is as
simple as running:
```shell
pkgx task
```
or, if you have pkgx integration enabled:
```shell
task
```
This installation method is community owned. After a new release of Task, they
are automatically released by pkgx in a minimum of time.
### Snap
Task is available in [Snapcraft][snapcraft], but keep in mind that your Linux
distribution should allow classic confinement for Snaps to Task work right:
```shell
sudo snap install task --classic
```
### Chocolatey
If you're on Windows and have [Chocolatey][choco] installed, getting Task is as
simple as running:
```shell
choco install go-task
```
This installation method is community owned.
### Scoop
If you're on Windows and have [Scoop][scoop] installed, getting Task is as
simple as running:
```shell
scoop install task
```
This installation method is community owned. After a new release of Task, it may
take some time until it's available on Scoop.
### AUR
If you're on Arch Linux you can install Task from
[AUR](https://aur.archlinux.org/packages/go-task-bin) using your favorite
package manager such as `yay`, `pacaur` or `yaourt`:
```shell
yay -S go-task-bin
```
Alternatively, there's
[this package](https://aur.archlinux.org/packages/go-task) which installs from
the source code instead of downloading the binary from the
[releases page](https://github.com/go-task/task/releases):
```shell
yay -S go-task
```
This installation method is community owned.
### Fedora
If you're on Fedora Linux you can install Task from the official
[Fedora](https://packages.fedoraproject.org/pkgs/golang-github-task/go-task/)
repository using `dnf`:
```shell
sudo dnf install go-task
```
This installation method is community owned. After a new release of Task, it may
take some time until it's available in
[Fedora](https://packages.fedoraproject.org/pkgs/golang-github-task/go-task/).
### Nix
If you're on NixOS or have Nix installed you can install Task from
[nixpkgs](https://github.com/NixOS/nixpkgs):
```shell
nix-env -iA nixpkgs.go-task
```
This installation method is community owned. After a new release of Task, it may
take some time until it's available in
[nixpkgs](https://github.com/NixOS/nixpkgs).
### npm
You can also use Node and npm to install Task by installing
[this package](https://www.npmjs.com/package/@go-task/cli).
```shell
npm install -g @go-task/cli
```
### Winget
If you are using Windows and installed the
[winget](https://github.com/microsoft/winget-cli) package management tool, you
can install Task from [winget-pkgs](https://github.com/microsoft/winget-pkgs).
```shell
winget install Task.Task
```
## Get The Binary
### Binary
You can download the binary from the [releases page on GitHub][releases] and add
to your `$PATH`.
DEB and RPM packages are also available.
The `task_checksums.txt` file contains the SHA-256 checksum for each file.
### Install Script
We also have an [install script][installscript] which is very useful in
scenarios like CI. Many thanks to [GoDownloader][godownloader] for enabling the
easy generation of this script.
By default, it installs on the `./bin` directory relative to the working
directory:
```shell
sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d
```
It is possible to override the installation directory with the `-b` parameter.
On Linux, common choices are `~/.local/bin` and `~/bin` to install for the
current user or `/usr/local/bin` to install for all users:
```shell
sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d -b ~/.local/bin
```
:::caution
On macOS and Windows, `~/.local/bin` and `~/bin` are not added to `$PATH` by
default.
:::
### GitHub Actions
If you want to install Task in GitHub Actions you can try using
[this action](https://github.com/arduino/setup-task) by the Arduino team:
```yaml
- name: Install Task
uses: arduino/setup-task@v1
with:
version: 3.x
repo-token: ${{ secrets.GITHUB_TOKEN }}
```
This installation method is community owned.
## Build From Source
### Go Modules
Ensure that you have a supported version of [Go][go] properly installed and
setup. You can find the minimum required version of Go in the
[go.mod](https://github.com/go-task/task/blob/main/go.mod#L3) file.
You can then install the latest release globally by running:
```shell
go install github.com/go-task/task/v3/cmd/task@latest
```
Or you can install into another directory:
```shell
env GOBIN=/bin go install github.com/go-task/task/v3/cmd/task@latest
```
:::tip
For CI environments we recommend using the [install script](#install-script)
instead, which is faster and more stable, since it'll just download the latest
released binary.
:::
## Setup completions
Download the autocompletion file corresponding to your shell.
[All completions are available on the Task repository](https://github.com/go-task/task/tree/main/completion).
### Bash
First, ensure that you installed bash-completion using your package manager.
Make the completion file executable:
```shell
chmod +x path/to/task.bash
```
After, add this to your `~/.bash_profile`:
```shell
source path/to/task.bash
```
### ZSH
Put the `_task` file somewhere in your `$FPATH`:
```shell
mv path/to/_task /usr/local/share/zsh/site-functions/_task
```
Ensure that the following is present in your `~/.zshrc`:
```shell
autoload -U compinit
compinit -i
```
ZSH version 5.7 or later is recommended.
### Fish
Move the `task.fish` completion script:
```shell
mv path/to/task.fish ~/.config/fish/completions/task.fish
```
### PowerShell
Open your profile script with:
```powershell
mkdir -Path (Split-Path -Parent $profile) -ErrorAction SilentlyContinue
notepad $profile
```
Add the line and save the file:
```shell
Invoke-Expression -Command path/to/task.ps1
```

# Integrations
## Visual Studio Code Extension
Task has an
[official extension for Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=task.vscode-task).
The code for this project can be found
[here](https://github.com/go-task/vscode-task). To use this extension, you must
have Task v3.23.0+ installed on your system.
This extension provides the following features (and more):
- View tasks in the sidebar.
- Run tasks from the sidebar and command palette.
- Go to definition from the sidebar and command palette.
- Run last task command.
- Multi-root workspace support.
- Initialize a Taskfile in the current workspace.
To get autocompletion and validation for your Taskfile, see the
[Schema](#schema) section below.
![Task for Visual Studio Code](https://github.com/go-task/vscode-task/blob/main/res/preview.png?raw=true)
## Schema
This was initially created by @KROSF in
[this Gist](https://gist.github.com/KROSF/c5435acf590acd632f71bb720f685895) and
is now officially maintained in
[this file](https://github.com/go-task/task/blob/main/docs/static/schema.json)
and made available at https://taskfile.dev/schema.json. This schema can be used
to validate Taskfiles and provide autocompletion in many code editors:
### Visual Studio Code
To integrate the schema into VS Code, you need to install the
[YAML extension](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-yaml)
by Red Hat. Any `Taskfile.yml` in your project should automatically be detected
and validation/autocompletion should work. If this doesn't work or you want to
manually configure it for files with a different name, you can add the following
to your `settings.json`:
```json
// settings.json
{
"yaml.schemas": {
"https://taskfile.dev/schema.json": [
"**/Taskfile.yml",
"./path/to/any/other/taskfile.yml"
]
}
}
```
You can also configure the schema directly inside of a Taskfile by adding the
following comment to the top of the file:
```yaml
# yaml-language-server: $schema=https://taskfile.dev/schema.json
version: '3'
```
You can find more information on this in the
[YAML language server project](https://github.com/redhat-developer/yaml-language-server).
## Community Integrations
In addition to our official integrations, there is an amazing community of
developers who have created their own integrations for Task:
- [Sublime Text Plugin](https://packagecontrol.io/packages/Taskfile)
[[source](https://github.com/biozz/sublime-taskfile)] by @biozz
- [IntelliJ Plugin](https://plugins.jetbrains.com/plugin/17058-taskfile)
[[source](https://github.com/lechuckroh/task-intellij-plugin)] by @lechuckroh
- [mk](https://github.com/pycontribs/mk) command line tool recognizes Taskfiles
natively.
If you have made something that integrates with Task, please feel free to open a
PR to add it to this list.

Task is a task runner / build tool that aims to be simpler and easier to use
than, for example, [GNU Make][make].
Since it's written in [Go][go], Task is just a single binary and has no other
dependencies, which means you don't need to mess with any complicated install
setups just to use a build tool.
Once [installed](/installation), you just need to describe your build tasks
using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
```yaml title="Taskfile.yml"
version: '3'
tasks:
hello:
cmds:
- echo 'Hello World from Task!'
silent: true
```
And call it by running `task hello` from your terminal.
The above example is just the start, you can take a look at the [usage](/usage)
guide to check the full schema documentation and Task features.
## Features
- [Easy installation](/installation): just download a single binary, add to
`$PATH` and you're done! Or you can also install using [Homebrew][homebrew],
[Snapcraft][snapcraft], or [Scoop][scoop] if you want.
- Available on CIs: by adding
[this simple command](/installation#install-script) to install on your CI
script and you're ready to use Task as part of your CI pipeline;
- Truly cross-platform: while most build tools only work well on Linux or macOS,
Task also supports Windows thanks to [this shell interpreter for Go][sh].
- Great for code generation: you can easily
[prevent a task from running](/usage#prevent-unnecessary-work) if a given set
of files haven't changed since last run (based either on its timestamp or
content).

# Releasing
The release process of Task is done with the help of [GoReleaser][goreleaser].
You can test the release process locally by calling the `test-release` task of
the Taskfile.
[GitHub Actions](https://github.com/go-task/task/actions) should release
artifacts automatically when a new Git tag is pushed to `main` branch (raw
executables and DEB and RPM packages).
Since v3.15.0, raw executables can also be reproduced and verified locally by
checking out a specific tag and calling `goreleaser build`, using the Go version
defined in the above GitHub Actions.
# Homebrew
Goreleaser will automatically push a new commit to the
[Formula/go-task.rb][gotaskrb] file in the [Homebrew tap][homebrewtap]
repository to release the new version.
# npm
To release to npm update the version in the [`package.json`][packagejson] file
and then run `task npm:publish` to push it.
# Snapcraft
The [snap package][snappackage] requires to manual steps to release a new
version:
- Updating the current version on [snapcraft.yaml][snapcraftyaml].
- Moving both `amd64`, `armhf` and `arm64` new artifacts to the stable channel
on the [Snapcraft dashboard][snapcraftdashboard].
# winget
winget also requires manual steps to be completed. By running
`task goreleaser:test` locally, manifest files will be generated on
`dist/winget/manifests/t/Task/Task/v{version}`.
[Upload the manifest directory into this fork](https://github.com/go-task/winget-pkgs/tree/master/manifests/t/Task/Task)
and open a pull request into
[this repository](https://github.com/microsoft/winget-pkgs).
# Scoop
Scoop is a command-line package manager for the Windows operating system. Scoop
package manifests are maintained by the community. Scoop owners usually take
care of updating versions there by editing
[this file](https://github.com/ScoopInstaller/Main/blob/master/bucket/task.json).
If you think its Task version is outdated, open an issue to let us know.
# Nix
Nix is a community owned installation method. Nix package maintainers usually
take care of updating versions there by editing
[this file](https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/development/tools/go-task/default.nix).
If you think its Task version is outdated, open an issue to let us know.

# Style guide
This is the official style guide for `Taskfile.yml` files. It provides basic
instructions for keeping your Taskfiles clean and familiar to other users.
This guide contains general guidelines, but they do not necessarily need to be
followed strictly. Feel free to disagree and do things differently if you need
or want to. Any improvements to this guide are welcome! Please open an issue or
create a pull request to contribute.
## Use the suggested ordering of the main sections
```yaml
version:
includes:
# optional configurations (output, silent, method, run, etc.)
vars:
env: # followed or replaced by dotenv
tasks:
```
## Use two spaces for indentation
This is the most common convention for YAML files, and Task follows it.
```yaml
# bad
tasks:
foo:
cmds:
- echo 'foo'
# good
tasks:
foo:
cmds:
- echo 'foo'
```
## Separate the main sections with empty lines
```yaml
# bad
version: '3'
includes:
docker: ./docker/Taskfile.yml
output: prefixed
vars:
FOO: bar
env:
BAR: baz
tasks:
# ...
# good
version: '3'
includes:
docker: ./docker/Taskfile.yml
output: prefixed
vars:
FOO: bar
env:
BAR: baz
tasks:
# ...
```
## Separate tasks with empty lines
```yaml
# bad
version: '3'
tasks:
foo:
cmds:
- echo 'foo'
bar:
cmds:
- echo 'bar'
baz:
cmds:
- echo 'baz'
# good
version: '3'
tasks:
foo:
cmds:
- echo 'foo'
bar:
cmds:
- echo 'bar'
baz:
cmds:
- echo 'baz'
```
## Use only uppercase letters for variable names
```yaml
# bad
version: '3'
vars:
binary_name: myapp
tasks:
build:
cmds:
- go build -o {{.binary_name}} .
# good
version: '3'
vars:
BINARY_NAME: myapp
tasks:
build:
cmds:
- go build -o {{.BINARY_NAME}} .
```
## Avoid using whitespace when templating variables
```yaml
# bad
version: '3'
tasks:
greet:
cmds:
- echo '{{ .MESSAGE }}'
# good
version: '3'
tasks:
greet:
cmds:
- echo '{{.MESSAGE}}'
```
This convention is also commonly used in templates for the Go programming
language.
## Use kebab case for task names
```yaml
# bad
version: '3'
tasks:
do_something_fancy:
cmds:
- echo 'Do something'
# good
version: '3'
tasks:
do-something-fancy:
cmds:
- echo 'Do something'
```
## Use a colon to separate the task namespace and name
```yaml
# good
version: '3'
tasks:
docker:build:
cmds:
- docker ...
docker:run:
cmds:
- docker-compose ...
```
This is also done automatically when using included Taskfiles.
## Prefer using external scripts instead of multi-line commands
```yaml
# bad
version: '3'
tasks:
build:
cmds:
- |
for i in $(seq 1 10); do
echo $i
echo "some other complex logic"
done'
# good
version: '3'
tasks:
build:
cmds:
- ./scripts/my_complex_script.sh
```

# Taskfile Versions
The Taskfile syntax and features changed with time. This document explains what
changed on each version and how to upgrade your Taskfile.
## What the Taskfile version mean
The Taskfile version follows the Task version. E.g. the change to Taskfile
version `2` means that Task `v2.0.0` should be release to support it.
The `version:` key on Taskfile accepts a semver string, so either `2`, `2.0` or
`2.0.0` is accepted. If you choose to use `2.0` Task will not enable future
`2.1` features, but if you choose to use `2`, then any `2.x.x` features will be
available, but not `3.0.0+`.
## Version 3 ![latest](https://img.shields.io/badge/latest-brightgreen)
These are some major changes done on `v3`:
- Task's output will now be colored
- Added support for `.env` like files
- Added `label:` setting to task so one can override how the task name appear in
the logs
- A global `method:` was added to allow setting the default method, and Task's
default changed to `checksum`
- Two magic variables were added when using `status:`: `CHECKSUM` and
`TIMESTAMP` which contains, respectively, the XXH3 checksum and greatest
modification timestamp of the files listed on `sources:`
- Also, the `TASK` variable is always available with the current task name
- CLI variables are always treated as global variables
- Added `dir:` option to `includes` to allow choosing on which directory an
included Taskfile will run:
```yaml
includes:
docs:
taskfile: ./docs
dir: ./docs
```
- Implemented short task syntax. All below syntaxes are equivalent:
```yaml
version: '3'
tasks:
print:
cmds:
- echo "Hello, World!"
```
```yaml
version: '3'
tasks:
print:
- echo "Hello, World!"
```
```yaml
version: '3'
tasks:
print: echo "Hello, World!"
```
- There was a major refactor on how variables are handled. They're now easier to
understand. The `expansions:` setting was removed as it became unnecessary.
This is the order in which Task will process variables, each level can see the
variables set by the previous one and override those.
- Environment variables
- Global + CLI variables
- Call variables
- Task variables
## Version 2.6
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
Version 2.6 comes with `preconditions` stanza in tasks.
```yaml
version: '2'
tasks:
upload_environment:
preconditions:
- test -f .env
cmds:
- aws s3 cp .env s3://myenvironment
```
Please check the [documentation][includes]
## Version 2.2
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
Version 2.2 comes with a global `includes` options to include other Taskfiles:
```yaml
version: '2'
includes:
docs: ./documentation # will look for ./documentation/Taskfile.yml
docker: ./DockerTasks.yml
```
## Version 2.1
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
Version 2.1 includes a global `output` option, to allow having more control over
how commands output are printed to the console (see [documentation][output] for
more info):
```yaml
version: '2'
output: prefixed
tasks:
server:
cmds:
- go run main.go
prefix: server
```
From this version it's also possible to ignore errors of a command or task
(check documentation [here][ignore_errors]):
```yaml
version: '2'
tasks:
example-1:
cmds:
- cmd: exit 1
ignore_error: true
- echo "This will be print"
example-2:
cmds:
- exit 1
- echo "This will be print"
ignore_error: true
```
## Version 2.0
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
At version 2, we introduced the `version:` key, to allow us to evolve Task with
new features without breaking existing Taskfiles. The new syntax is as follows:
```yaml
version: '2'
tasks:
echo:
cmds:
- echo "Hello, World!"
```
Version 2 allows you to write global variables directly in the Taskfile, if you
don't want to create a `Taskvars.yml`:
```yaml
version: '2'
vars:
GREETING: Hello, World!
tasks:
greet:
cmds:
- echo "{{.GREETING}}"
```
The variable priority order changed to the following:
1. Task variables
2. Call variables
3. Taskfile variables
4. Taskvars file variables
5. Environment variables
A new global option was added to configure the number of variables expansions
(which default to 2):
```yaml
version: '2'
expansions: 3
vars:
FOO: foo
BAR: bar
BAZ: baz
FOOBAR: '{{.FOO}}{{.BAR}}'
FOOBARBAZ: '{{.FOOBAR}}{{.BAZ}}'
tasks:
default:
cmds:
- echo "{{.FOOBARBAZ}}"
```
## Version 1
:::caution
v1 schema support was removed in Task >= v3.0.0.
:::
In the first version of the `Taskfile`, the `version:` key was not available,
because the tasks was in the root of the YAML document. Like this:
```yaml
echo:
cmds:
- echo "Hello, World!"
```
The variable priority order was also different:
1. Call variables
2. Environment
3. Task variables
4. `Taskvars.yml` variables

# Donate
If you find this project useful, you can consider donating by using one of the
channels listed below.
This is just a way of saying "thank you", it won't give you any benefits like
higher priority on issues or something similar.
Companies who donate at least $50/month will be featured as a "Gold Sponsor" in
the website homepage and on the GitHub repository README. Make contact with
[@andreynering] with the logo you want to be shown. Suspect businesses
(gambling, casinos, etc) won't be allowed, though.
## GitHub Sponsors
The preferred way to donate to the maintainers is via GitHub Sponsors. Just use
the following links to do your donation. We suggest a 50/50 split to each
maintainer of the total amount you plan to donate to the project.
- [@andreynering](https://github.com/sponsors/andreynering)
- [@pd93](https://github.com/sponsors/pd93)
## Open Collective

by using these links:
- [$2 per month](https://opencollective.com/task/contribute/backer-4034/checkout)
- [$5 per month](https://opencollective.com/task/contribute/supporter-8404/checkout)
- [$20 per month](https://opencollective.com/task/contribute/sponsor-4035/checkout)
- [$50 per month](https://opencollective.com/task/contribute/sponsor-28775/checkout)
- [Custom value - One-time donation option supported](https://opencollective.com/task/donate)
## PayPal
You can donate to [@andreynering] via PayPal as well:

## CLI
Task command line tool has the following syntax:
```shell
task [--flags] [tasks...] [-- CLI_ARGS...]
```
:::tip
If `--` is given, all remaining arguments will be assigned to a special
`CLI_ARGS` variable
:::

| ----- | --------------------------- | -------- | -------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `-c` | `--color` | `bool` | `true` | Colored output. Enabled by default. Set flag to `false` or use `NO_COLOR=1` to disable. |
| `-C` | `--concurrency` | `int` | `0` | Limit number tasks to run concurrently. Zero means unlimited. |
| `-d` | `--dir` | `string` | Working directory | Sets directory of execution. |
| `-n` | `--dry` | `bool` | `false` | Compiles and prints tasks in the order that they would be run, without executing them. |
| `-x` | `--exit-code` | `bool` | `false` | Pass-through the exit code of the task command. |
| `-f` | `--force` | `bool` | `false` | Forces execution even when the task is up-to-date. |
| `-g` | `--global` | `bool` | `false` | Runs global Taskfile, from `$HOME/Taskfile.{yml,yaml}`. |
| `-h` | `--help` | `bool` | `false` | Shows Task usage. |
| `-i` | `--init` | `bool` | `false` | Creates a new Taskfile.yml in the current folder. |
| `-I` | `--interval` | `string` | `5s` | Sets a different watch interval when using `--watch`, the default being 5 seconds. This string should be a valid [Go Duration](https://pkg.go.dev/time#ParseDuration). |
| `-l` | `--list` | `bool` | `false` | Lists tasks with description of current Taskfile. |
| `-a` | `--list-all` | `bool` | `false` | Lists tasks with or without a description. |
| | `--sort` | `string` | `default` | Changes the order of the tasks when listed.<br />`default` - Alphanumeric with root tasks first<br />`alphanumeric` - Alphanumeric<br />`none` - No sorting (As they appear in the Taskfile) |
| | `--json` | `bool` | `false` | See [JSON Output](#json-output) |
| `-o` | `--output` | `string` | Default set in the Taskfile or `intervealed` | Sets output style: [`interleaved`/`group`/`prefixed`]. |
| | `--output-group-begin` | `string` | | Message template to print before a task's grouped output. |
| | `--output-group-end` | `string` | | Message template to print after a task's grouped output. |
| | `--output-group-error-only` | `bool` | `false` | Swallow command output on zero exit code. |
| `-p` | `--parallel` | `bool` | `false` | Executes tasks provided on command line in parallel. |
| `-s` | `--silent` | `bool` | `false` | Disables echoing. |
| `-y` | `--yes` | `bool` | `false` | Assume "yes" as answer to all prompts. |

| | `--summary` | `bool` | `false` | Show summary about a task. |
| `-t` | `--taskfile` | `string` | `Taskfile.yml` or `Taskfile.yaml` | |
| `-v` | `--verbose` | `bool` | `false` | Enables verbose mode. |
| | `--version` | `bool` | `false` | Show Task version. |
| `-w` | `--watch` | `bool` | `false` | Enables watch of the given task. |
## Exit Codes
Task will sometimes exit with specific exit codes. These codes are split into
three groups with the following ranges:
- General errors (0-99)
- Taskfile errors (100-199)
- Task errors (200-299)
A full list of the exit codes and their descriptions can be found below:

These codes can also be found in the repository in
[`errors/errors.go`](https://github.com/go-task/task/blob/main/errors/errors.go).
:::info
When Task is run with the `-x`/`--exit-code` flag, the exit code of any failed
commands will be passed through to the user instead.
:::
## JSON Output
When using the `--json` flag in combination with either the `--list` or
`--list-all` flags, the output will be a JSON object with the following
structure:
```json
{
"tasks": [

"name": "",
"desc": "",
"summary": "",
"up_to_date": false,
"location": {
"line": 54,

| `interactive` | `bool` | `false` | Tells task that the command is interactive. |
| `internal` | `bool` | `false` | Stops a task from being callable on the command line. It will also be omitted from the output when used with `--list`. |
| `method` | `string` | `checksum` | Defines which method is used to check the task is up-to-date. `timestamp` will compare the timestamp of the sources and generates files. `checksum` will check the checksum (You probably want to ignore the .task folder in your .gitignore file). `none` skips any validation and always run the task. |
| `prefix` | `string` | | Defines a string to prefix the output of tasks running in parallel. Only used when the output mode is `prefixed`. |
| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing commands. |

| `cmd` | `string` | | The shell command to be executed. |
| `task` | `string` | | Set this to trigger execution of another task instead of running a command. This cannot be set together with `cmd`. |
| `for` | [`For`](#for) | | Runs the command once for each given value. |
| `silent` | `bool` | `false` | Skips some output for this command. Note that STDOUT and STDERR of the commands will still be redirected. |
| `vars` | [`map[string]Variable`](#variable) | | Optional additional variables to be passed to the referenced task. Only relevant when setting `task` instead of `cmd`. |
| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing the command. |

| `silent` | `bool` | `false` | Hides task name and command from output. The command's output will still be redirected to `STDOUT` and `STDERR`. |
:::tip
If you don't want to set additional variables, it's enough to declare the
dependency as a list of strings (they will be assigned to `task`):
```yaml
tasks:
foo:
deps: [foo, bar]
```
:::
#### For
The `for` parameter can be defined as a string, a list of strings or a map. If
it is defined as a string, you can give it any of the following values:
- `source` - Will run the command for each source file defined on the task.
(Glob patterns will be resolved, so `*.go` will run for every Go file that
matches).
If it is defined as a list of strings, the command will be run for each value.
Finally, the `for` parameter can be defined as a map when you want to use a
variable to define the values to loop over:
| Attribute | Type | Default | Description |
| --------- | -------- | ---------------- | -------------------------------------------- |
| `var` | `string` | | The name of the variable to use as an input. |
| `split` | `string` | (any whitespace) | What string the variable should be split on. |

like this and the value will be assigned to `sh`:
```yaml
tasks:
foo:
precondition: test -f Taskfile.yml
```
:::
#### Requires
| Attribute | Type | Default | Description |
| --------- | ---------- | ------- | -------------------------------------------------------------------------------------------------- |
| `vars` | `[]string` | | List of variable or environment variable names that must be set if this task is to execute and run |

@andarto, #1309 by @andreynering).
- Fix bug on `--status` flag. Running this flag should not have side-effects: it
should not update the checksum on `.task`, only report its status (#1305,
#1307 by @visciang, #1313 by @andreynering).
## v3.28.0 - 2023-07-24
- Added the ability to
[loop over commands and tasks](https://taskfile.dev/usage/#looping-over-values)
using `for` (#82, #1220 by @pd93).

draft (#1200, #1216 by @pd93).
- Added an `--experiments` flag to allow you to see which experiments are
enabled (#1242 by @pd93).
- Added ability to specify which variables are required in a task (#1203, #1204
by @benc-uk).
## v3.26.0 - 2023-06-10
- Only rewrite checksum files in `.task` if the checksum has changed (#1185,
#1194 by @deviantintegral).
- Added [experiments documentation](https://taskfile.dev/experiments) to the
website (#1198 by @pd93).
- Deprecated `version: 2` schema. This will be removed in the next major release
(#1197, #1198, #1199 by @pd93).
- Added a new `prompt:` prop to set a warning prompt to be shown before running
a potential dangurous task (#100, #1163 by @MaxCheetham,
[Documentation](https://taskfile.dev/usage/#warning-prompts)).
- Added support for single command task syntax. With this change, it's now
possible to declare just `cmd:` in a task, avoiding the more complex
`cmds: []` when you have only a single command for that task (#1130, #1131 by
@timdp).
## v3.25.0 - 2023-05-22
- Support `silent:` when calling another tasks (#680, #1142 by @danquah).

- The default branch was renamed from `master` to `main` (#1049, #1048 by
@pd93).
- Fix bug where "up-to-date" logs were not being omitted for silent tasks (#546,
#1107 by @danquah).
- Add `.hg` (Mercurial) to the list of ignored directories when using `--watch`
(#1098 by @misery).
- More improvements to the release tool (#1096 by @pd93).

- Add `--sort` flag for use with `--list` and `--list-all` (#946, #1105 by
@pd93).
- Task now has [custom exit codes](https://taskfile.dev/api/#exit-codes)
depending on the error (#1114 by @pd93).

> **NOTE:** The extension _requires_ v3.23.0 to be installed in order to work.
- The website was integrated with
[Crowdin](https://crowdin.com/project/taskfile) to allow the community to
contribute with translations! [Chinese](https://taskfile.dev/zh-Hans/) is the
first language available (#1057, #1058 by @misitebao).
- Added task location data to the `--json` flag output (#1056 by @pd93)
- Change the name of the file generated by `task --init` from `Taskfile.yaml` to
`Taskfile.yml` (#1062 by @misitebao).
- Added new `splitArgs` template function
(`{{splitArgs "foo bar 'foo bar baz'"}}`) to ensure string is split as
arguments (#1040, #1059 by @dhanusaputra).
- Fix the value of `{{.CHECKSUM}}` variable in status (#1076, #1080 by @pd93).
- Fixed deep copy implementation (#1072 by @pd93)

## v3.22.0 - 2023-03-10
- Add a brand new `--global` (`-g`) flag that will run a Taskfile from your
`$HOME` directory. This is useful to have automation that you can run from
anywhere in your system!
([Documentation](https://taskfile.dev/usage/#running-a-global-taskfile), #1029
by @andreynering).
- Add ability to set `error_only: true` on the `group` output mode. This will
instruct Task to only print a command output if it returned with a non-zero
exit code (#664, #1022 by @jaedle).
- Fixed bug where `.task/checksum` file was sometimes not being created when
task also declares a `status:` (#840, #1035 by @harelwa, #1037 by @pd93).
- Refactored and decoupled fingerprinting from the main Task executor (#1039 by
@pd93).
- Fixed deadlock issue when using `run: once` (#715, #1025 by
@theunrepentantgeek).
## v3.21.0 - 2023-02-22
- Added new `TASK_VERSION` special variable (#990, #1014 by @ja1code).

- Improve behavior and performance of status checking when using the `timestamp`
mode (#976, #977 by @aminya).
- Performance optimizations were made for large Taskfiles (#982 by @pd93).
- Add ability to configure options for the
[`set`](https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html)
and
[`shopt`](https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html)
builtins (#908, #929 by @pd93,
[Documentation](http://taskfile.dev/usage/#set-and-shopt)).
- Add new `platforms:` attribute to `task` and `cmd`, so it's now possible to
choose in which platforms that given task or command will be run on. Possible
values are operating system (GOOS), architecture (GOARCH) or a combination of
the two. Example: `platforms: [linux]`, `platforms: [amd64]` or
`platforms: [linux/amd64]`. Other platforms will be skipped (#978, #980 by
@leaanthony).

(#969, #970 by @pd93)
- Add `--json` flag (alias `-j`) with the intent to improve support for code
editors and add room to other possible integrations. This is basic for now,
but we plan to add more info in the near future (#936 by @davidalpert, #764).
## v3.19.0 - 2022-12-05
- Installation via npm now supports [pnpm](https://pnpm.io/) as well
([go-task/go-npm#2](https://github.com/go-task/go-npm/issues/2),
[go-task/go-npm#3](https://github.com/go-task/go-npm/pull/3)).

- Fixed bug when using the `output: group` mode where STDOUT and STDERR were
being print in separated blocks instead of in the right order (#779).
- Starting on this release, ARM architecture binaries are been released to Snap
as well (#795).
- i386 binaries won't be available anymore on Snap because Ubuntu removed the
support for this architecture.
- Upgrade mvdan.cc/sh, which fixes a bug with associative arrays (#785,

# Contributing
Contributions to Task are very welcome, but we ask that you read this document
before submitting a PR.
:::note
This document applies to the core [Task][task] repository _and_ [Task for Visual
Studio Code][vscode-task].
:::
## Before you start
- **Check existing work** - Is there an existing PR? Are there issues discussing
the feature/change you want to make? Please make sure you consider/address
these discussions in your work.
- **Backwards compatibility** - Will your change break existing Taskfiles? It is
much more likely that your change will merged if it backwards compatible. Is
there an approach you can take that maintains this compatibility? If not,
consider opening an issue first so that API changes can be discussed before
you invest your time into a PR.
- **Experiments** - If there is no way to make your change backward compatible
then there is a procedure to introduce breaking changes into minor versions.
We call these "[experiments][experiments]". If you're intending to work on an
experiment, then please read the [experiments workflow][experiments-workflow]
document carefully and submit a proposal first.
## 1. Setup
- **Go** - Task is written in [Go][go]. We always support the latest two major
Go versions, so make sure your version is recent enough.
- **Node.js** - [Node.js][nodejs] is used to host Task's documentation server
and is required if you want to run this server locally. It is also required if
you want to contribute to the Visual Studio Code extension.
- **Yarn** - [Yarn][yarn] is the Node.js package manager used by Task.
## 2. Making changes
- **Code style** - Try to maintain the existing code style where possible. Go
code should be formatted by [`gofumpt`][gofumpt] and linted using
[`golangci-lint`][golangci-lint]. Any Markdown or TypeScript files should be
formatted and linted by [Prettier][prettier]. This style is enforced by our CI
to ensure that we have a consistent style across the project. You can use the
`task lint` command to lint the code locally and the `task lint:fix` command
to automatically fix any issues that are found.
- **Documentation** - Ensure that you add/update any relevant documentation. See
the [updating documentation](#updating-documentation) section below.
- **Tests** - Ensure that you add/update any relevant tests and that all tests
are passing before submitting the PR. See the [writing tests](#writing-tests)
section below.
### Running your changes
To run Task with working changes, you can use `go run ./cmd/task`. To run a
development build of task against a test Taskfile in `testdata`, you can use
`go run ./cmd/task --dir ./testdata/<my_test_dir> <task_name>`.
To run Task for Visual Studio Code, you can open the project in VSCode and hit
F5 (or whatever you debug keybind is set to). This will open a new VSCode window
with the extension running. Debugging this way is recommended as it will allow
you to set breakpoints and step through the code. Otherwise, you can run
`task package` which will generate a `.vsix` file that can be used to manually
install the extension.
### Updating documentation
Task uses [Docusaurus][docusaurus] to host a documentation server. The code for
this is located in the core Task repository. This can be setup and run locally
by using `task docs` (requires `nodejs` & `yarn`). All content is written in
Markdown and is located in the `docs/docs` directory. All Markdown documents
should have an 80 character line wrap limit (enforced by Prettier).
When making a change, consider whether a change to the [Usage
Guide](/usage) is necessary. This document contains descriptions and
examples of how to use Task features. If you're adding a new feature, try to
find an appropriate place to add a new section. If you're updating an existing
feature, ensure that the documentation and any examples are up-to-date. Ensure
that any examples follow the [Taskfile Styleguide](/styleguide).
If you added a new field, command or flag, ensure that you add it to the
[API Reference](/api). New fields also need to be added to the
[JSON Schema][json-schema]. The descriptions for fields in the API reference and
the schema should match.
### Writing tests
A lot of Task's tests are held in the `task_test.go` file in the project root
and this is where you'll most likely want to add new ones too. Most of these
tests also have a subdirectory in the `testdata` directory where any
Taskfiles/data required to run the tests are stored.
When making a changes, consider whether new tests are required. These tests
should ensure that the functionality you are adding will continue to work in the
future. Existing tests may also need updating if you have changed Task's
behavior.
You may also consider adding unit tests for any new functions you have added.
The unit tests should follow the Go convention of being location in a file named
`*_test.go` in the same package as the code being tested.
## 3. Committing your code
Try to write meaningful commit messages and avoid having too many commits on the
PR. Most PRs should likely have a single commit (although for bigger PRs it may
be reasonable to split it in a few). Git squash and rebase is your friend!
If you're not sure how to format your commit message, check out [Conventional
Commits][conventional-commits]. This style is not enforced, but it is a good way
to make your commit messages more readable and consistent.
## 4. Submitting a PR
- **Describe your changes** - Ensure that you provide a comprehensive
description of your changes.
- **Issue/PR links** - Link any previous work such as related issues or PRs.
Please describe how your changes differ to/extend this work.
- **Examples** - Add any examples or screenshots that you think are useful to
demonstrate the effect of your changes.
- **Draft PRs** - If your changes are incomplete, but you would like to discuss
them, open the PR as a draft and add a comment to start a discussion. Using
comments rather than the PR description allows the description to be updated
later while preserving any discussions.
## FAQ
> I want to contribute, where do I start?
Take a look at the list of [open issues for Task][task-open-issues] or [Task for
Visual Studio Code][vscode-task-open-issues]. We have a [good first
issue][good-first-issue] label for simpler issues that are ideal for first time
contributions.
All kinds of contributions are welcome, whether its a typo fix or a shiny new
feature. You can also contribute by upvoting/commenting on issues, helping to
answer questions or contributing to other [community projects](/community).
> I'm stuck, where can I get help?
If you have questions, feel free to ask them in the `#help` forum channel on our
[Discord server][discord-server] or open a [Discussion][discussion] on GitHub.

# Deprecations
As Task evolves, it occasionally outgrows some of its functionality. This can be
because they are no longer useful, because another feature has replaced it or
because of a change in the way that Task works internally.
When this happens, we mark the functionality as deprecated. This means that it
will be removed in a future version of Task. This functionality will continue to
work until that time, but we strongly recommend that you do not implement this
functionality in new Taskfiles and make a plan to migrate away from it as soon
as possible.
You can view a full list of active deprecations in the "Deprecations" section of
the sidebar.

# Version 2 Schema (#1197)
:::warning
This deprecation breaks the following functionality:
- Any Taskfiles that use the version 2 schema
- `Taskvar.yml` files
:::
The Taskfile version 2 schema was introduced in March 2018 and replaced by
version 3 in August 2019. In May 2023 [we published a deprecation
notice][deprecation-notice] for the version 2 schema on the basis that the vast
majority of users had already upgraded to version 3 and removing support for
version 2 would allow us to tidy up the codebase and focus on new functionality
instead.
In December 2023, the final version of Task that supports the version 2 schema
([v3.33.0][v3.33.0]) was published and all legacy code was removed from Task's
main branch. To use a more recent version of Task, you will need to ensure that
your Taskfile uses the version 3 schema instead. A list of changes between
version 2 and version 3 are available in the [Task v3 Release Notes][v3.0.0].

# Any Variables (#1415)
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
Currently, Task only supports string variables. This experiment allows you to
specify and use the following variable types:
- `string`
- `bool`
- `int`
- `float`
- `array`
- `map`
This allows you to have a lot more flexibility in how you use variables in
Task's templating engine. There are two active proposals for this experiment.
Click on the tabs below to switch between them.
<Tabs defaultValue="1" queryString="proposal"
values={[
{label: 'Proposal 1', value: '1'},
{label: 'Proposal 2', value: '2'}
]}>
<TabItem value="1">
:::warning
This experiment proposal breaks the following functionality:
- Dynamically defined variables (using the `sh` keyword)
:::
:::info
To enable this experiment, set the environment variable:
`TASK_X_ANY_VARIABLES=1`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
## Maps
This proposal removes support for the `sh` keyword in favour of a new syntax for
dynamically defined variables, This allows you to define a map directly as you
would for any other type:
```yaml
version: 3
tasks:
foo:
vars:
FOO: {a: 1, b: 2, c: 3} # <-- Directly defined map on the `FOO` key
cmds:
- 'echo {{.FOO.a}}'
```
## Migration
Taskfiles with dynamically defined variables via the `sh` subkey will no longer
work with this experiment enabled. In order to keep using dynamically defined
variables, you will need to migrate your Taskfile to use the new syntax.
Previously, you might have defined a dynamic variable like this:
```yaml
version: 3
tasks:
foo:
vars:
CALCULATED_VAR:
sh: 'echo hello'
cmds:
- 'echo {{.CALCULATED_VAR}}'
```
With this experiment enabled, you will need to remove the `sh` subkey and define
your command as a string that begins with a `$`. This will instruct Task to
interpret the string as a command instead of a literal value and the variable
will be populated with the output of the command. For example:
```yaml
version: 3
tasks:
foo:
vars:
CALCULATED_VAR: '$echo hello'
cmds:
- 'echo {{.CALCULATED_VAR}}'
```
If your current Taskfile contains a string variable that begins with a `$`, you
will now need to escape the `$` with a backslash (`\`) to stop Task from
executing it as a command.
</TabItem>
<TabItem value="2">
:::info
To enable this experiment, set the environment variable:
`TASK_X_ANY_VARIABLES=2`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
## Maps
This proposal maintains backwards-compatibility and the `sh` subkey and adds
another new `map` subkey for defining map variables:
```yaml
version: 3
tasks:
foo:
vars:
FOO:
map: {a: 1, b: 2, c: 3} # <-- Defined using the `map' subkey instead of directly on 'FOO'
BAR: true # <-- Other types of variables are still defined directly on the key
BAZ:
sh: 'echo Hello Task' # <-- The `sh` subkey is still supported
cmds:
- 'echo {{.FOO.a}}'
```
## Parsing JSON and YAML
In addition to the new `map` keyword, this proposal also adds support for the
`json` and `yaml` keywords for parsing JSON and YAML strings into real
objects/arrays. This is similar to the `fromJSON` template function, but means
that you only have to parse the JSON/YAML once when you declare the variable,
instead of every time you want to access a value.
Before:
```yaml
version: 3
tasks:
foo:
vars:
FOO: '{"a": 1, "b": 2, "c": 3}' # <-- JSON string
cmds:
- 'echo {{(fromJSON .FOO).a}}' # <-- Parse JSON string every time you want to access a value
- 'echo {{(fromJSON .FOO).b}}'
```
After:
```yaml
version: 3
tasks:
foo:
vars:
FOO:
json: '{"a": 1, "b": 2, "c": 3}' # <-- JSON string parsed once
cmds:
- 'echo {{.FOO.a}}' # <-- Access values directly
- 'echo {{.FOO.b}}'
```
## Variables by reference
Lastly, this proposal adds support for defining and passing variables by
reference. This is really important now that variables can be types other than a
string. Previously, to send a variable from one task to another, you would have
to use the templating system to pass it:
```yaml
version: 3
tasks:
foo:
vars:
FOO: [A, B, C] # <-- FOO is defined as an array
cmds:
- task: bar
vars:
FOO: '{{.FOO}}' # <-- FOO gets converted to a string when passed to bar
bar:
cmds:
- 'echo {{index .FOO 0}}' # <-- FOO is a string so the task outputs '91' which is the ASCII code for '[' instead of the expected 'A'
```
Unfortunately, this results in the value always being passed as a string as this
is the output type of the templater and operations on the passed variable may
not behave as expected. With this proposal, you can now pass variables by
reference using the `ref` subkey:
```yaml
version: 3
tasks:
foo:
vars:
FOO: [A, B, C] # <-- FOO is defined as an array
cmds:
- task: bar
vars:
FOO:
ref: FOO # <-- FOO gets passed by reference to bar and maintains its type
bar:
cmds:
- 'echo {{index .FOO 0}}' # <-- FOO is still a map so the task outputs 'A' as expected
```
This means that the type of the variable is maintained when it is passed to
another Task. This also works the same way when calling `deps` and when defining
a variable and can be used in any combination:
```yaml
version: 3
tasks:
foo:
vars:
FOO: [A, B, C] # <-- FOO is defined as an array
BAR:
ref: FOO # <-- BAR is defined as a reference to FOO
deps:
- task: bar
vars:
BAR:
ref: BAR # <-- BAR gets passed by reference to bar and maintains its type
bar:
cmds:
- 'echo {{index .BAR 0}}' # <-- BAR still refers to FOO so the task outputs 'A'
```
</TabItem></Tabs>
---
## Common to both proposals
Both proposals add support for all other variable types by directly defining
them in the Taskfile. For example:
### Evaluating booleans
```yaml
version: 3
tasks:
foo:
vars:
BOOL: false
cmds:
- '{{if .BOOL}}echo foo{{end}}'
```
### Arithmetic
```yaml
version: 3
tasks:
foo:
vars:
INT: 10
FLOAT: 3.14159
cmds:
- 'echo {{add .INT .FLOAT}}'
```
### Ranging
```yaml
version: 3
tasks:
foo:
vars:
ARRAY: [1, 2, 3]
cmds:
- 'echo {{range .ARRAY}}{{.}}{{end}}'
```
There are many more templating functions which can be used with the new types of
variables. For a full list, see the [slim-sprig][slim-sprig] documentation.
## Looping over variables
Previously, you would have to use a delimiter separated string to loop over an
arbitrary list of items in a variable and split them by using the `split` subkey
to specify the delimiter:
```yaml
version: 3
tasks:
foo:
vars:
LIST: 'foo,bar,baz'
cmds:
- for:
var: LIST
split: ','
cmd: echo {{.ITEM}}
```
Both of these proposals add support for looping over "collection-type" variables
using the `for` keyword, so now you are able to loop over a map/array variable
directly:
```yaml
version: 3
tasks:
foo:
vars:
LIST: [foo, bar, baz]
cmds:
- for:
var: LIST
cmd: echo {{.ITEM}}
```
When looping over a map we also make an additional `{{.KEY}}` variable availabe
that holds the string value of the map key. Remember that maps are unordered, so
the order in which the items are looped over is random.

# Experiments
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
In order to allow Task to evolve quickly, we sometimes roll out breaking changes
to minor versions behind experimental flags. This allows us to gather feedback
on breaking changes before committing to a major release. This process can also
be used to gather feedback on important non-breaking features before their
design is completed. This document describes the
[experiment workflow](#workflow) and how you can get involved.
You can view the full list of active experiments in the sidebar submenu to the
left of the page and click on each one to find out more about it.
## Enabling Experiments
Task uses environment variables to detect whether or not an experiment is
enabled. All of the experiment variables will begin with the same `TASK_X_`
prefix followed by the name of the experiment. You can find the exact name for
each experiment on their respective pages in the sidebar. If the variable is set
`=1` then it will be enabled. Some experiments may have multiple proposals, in
which case, you will need to set the variable equal to the number of the
proposal that you want to enable (`=2`, `=3` etc).
There are three main ways to set the environment variables for an experiment.
Which method you use depends on how you intend to use the experiment:
1. Prefixing your task commands with the relevant environment variable(s). For
example, `TASK_X_{FEATURE}=1 task {my-task}`. This is intended for one-off
invocations of Task to test out experimental features.
1. Adding the relevant environment variable(s) in your "dotfiles" (e.g.
`.bashrc`, `.zshrc` etc.). This will permanently enable experimental features
for your personal environment.
```shell title="~/.bashrc"
export TASK_X_FEATURE=1
```
1. Creating a `.env` file in the same directory as your root Taskfile that
contains the relevant environment variable(s). This allows you to enable an
experimental feature at a project level. If you commit the `.env` file to
source control then other users of your project will also have these
experiments enabled.
```shell title=".env"
TASK_X_FEATURE=1
```
## Workflow
Experiments are a way for us to test out new features in Task before committing
to them in a major release. Because this concept is built around the idea of
feedback from our community, we have built a workflow for the process of
introducing these changes. This ensures that experiments are given the attention
and time that they need and that we are getting the best possible results out of
them.
The sections below describe the various stages that an experiment must go
through from its proposal all the way to being released in a major version of
Task.
### 1. Proposal
All experimental features start with a proposal in the form of a GitHub issue.
If the maintainers decide that an issue has enough support and is a breaking
change or is complex/controversial enough to require user feedback, then the
issue will be marked with the `experiment: proposal` label. At this point, the
issue becomes a proposal and a period of consultation begins. During this
period, we request that users provide feedback on the proposal and how it might
effect their use of Task. It is up to the discretion of the maintainers to
decide how long this period lasts.
### 2. Draft
Once a proposal's consultation ends, a contributor may pick up the work and
begin the initial implementation. Once a PR is opened, the maintainers will
ensure that it meets the requirements for an experimental feature (i.e. flags
are in the right format etc) and merge the feature. Once this code is released,
the status will be updated via the `experiment: draft` label. This indicates
that an implementation is now available for use in a release and the experiment
is open for feedback.
:::note
During the draft period, major changes to the implementation may be made based
on the feedback received from users. There are _no stability guarantees_ and
experimental features may be abandoned _at any time_.
:::
### 3. Candidate
Once an acceptable level of consensus has been reached by the community and
feedback/changes are less frequent/significant, the status may be updated via
the `experiment: candidate` label. This indicates that a proposal is _likely_ to
accepted and will enter a period for final comments and minor changes.
### 4. Stable
Once a suitable amount of time has passed with no changes or feedback, an
experiment will be given the `experiment: stable` label. At this point, the
functionality will be treated like any other feature in Task and any changes
_must_ be backward compatible. This allows users to migrate to the new
functionality without having to worry about anything breaking in future
releases. This provides the best experience for users migrating to a new major
version.
### 5. Released
When making a new major release of Task, all experiments marked as
`experiment: stable` will move to `experiment: released` and their behaviors
will become the new default in Task. Experiments in an earlier stage (i.e. not
stable) cannot be released and so will continue to be experiments in the new
version.
### Abandoned / Superseded
If an experiment is unsuccessful at any point then it will be given the
`experiment: abandoned` or `experiment: superseded` labels depending on which is
more suitable. These experiments will be removed from Task.

# Gentle Force (#1200)
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
:::warning
This experiment breaks the following functionality:
- The `--force` flag
:::
:::info
To enable this experiment, set the environment variable: `TASK_X_FORCE=1`. Check
out [our guide to enabling experiments ][enabling-experiments] for more
information.
:::
The `--force` flag currently forces _all_ tasks to run regardless of the status
checks. This can be useful, but we have found that most of the time users only
expect the direct task they are calling to be forced and _not_ all of its
dependant tasks.
This experiment changes the `--force` flag to only force the directly called
task. All dependant tasks will have their statuses checked as normal and will
only run if Task considers them to be out of date. A new `--force-all` flag will
also be added to maintain the current behavior for users that need this
functionality.
If you want to migrate, but continue to force all dependant tasks to run, you
should replace all uses of the `--force` flag with `--force-all`. Alternatively,
if you want to adopt the new behavior, you can continue to use the `--force`
flag as you do now!

# Remote Taskfiles (#1317)
:::caution
All experimental features are subject to breaking changes and/or removal _at any
time_. We strongly recommend that you do not use these features in a production
environment. They are intended for testing and feedback only.
:::
:::info
To enable this experiment, set the environment variable:
`TASK_X_REMOTE_TASKFILES=1`. Check out [our guide to enabling experiments
][enabling-experiments] for more information.
:::
This experiment allows you to specify a remote Taskfile URL when including a
Taskfile. For example:
```yaml
version: '3'
includes:
my-remote-namespace: https://raw.githubusercontent.com/my-org/my-repo/main/Taskfile.yml
```
This works exactly the same way that including a local file does. Any tasks in
the remote Taskfile will be available to run from your main Taskfile via the
namespace `my-remote-namespace`. For example, if the remote file contains the
following:
```yaml
version: '3'
tasks:
hello:
silent: true
cmds:
- echo "Hello from the remote Taskfile!"
```
and you run `task my-remote-namespace:hello`, it will print the text: "Hello
from the remote Taskfile!" to your console.
## Security
Running commands from sources that you do not control is always a potential
security risk. For this reason, we have added some checks when using remote
Taskfiles:
1. When running a task from a remote Taskfile for the first time, Task will
print a warning to the console asking you to check that you are sure that you
trust the source of the Taskfile. If you do not accept the prompt, then Task
will exit with code `104` (not trusted) and nothing will run. If you accept
the prompt, the remote Taskfile will run and further calls to the remote
Taskfile will not prompt you again.
2. Whenever you run a remote Taskfile, Task will create and store a checksum of
the file that you are running. If the checksum changes, then Task will print
another warning to the console to inform you that the contents of the remote
file has changed. If you do not accept the prompt, then Task will exit with
code `104` (not trusted) and nothing will run. If you accept the prompt, the
checksum will be updated and the remote Taskfile will run.
Sometimes you need to run Task in an environment that does not have an
interactive terminal, so you are not able to accept a prompt. In these cases you
are able to tell task to accept these prompts automatically by using the `--yes`
flag. Before enabling this flag, you should:
1. Be sure that you trust the source and contents of the remote Taskfile.
2. Consider using a pinned version of the remote Taskfile (e.g. A link
containing a commit hash) to prevent Task from automatically accepting a
prompt that says a remote Taskfile has changed.
Task currently supports both `http` and `https` URLs. However, the `http`
requests will not execute by default unless you run the task with the
`--insecure` flag. This is to protect you from accidentally running a remote
Taskfile that is hosted on and unencrypted connection. Sources that are not
protected by TLS are vulnerable to [man-in-the-middle
attacks][man-in-the-middle-attacks] and should be avoided unless you know what
you are doing.
## Caching & Running Offline
Whenever you run a remote Taskfile, the latest copy will be downloaded from the
internet and cached locally. If for whatever reason, you lose access to the
internet, you will still be able to run your tasks by specifying the `--offline`
flag. This will tell Task to use the latest cached version of the file instead
of trying to download it. You are able to use the `--download` flag to update
the cached version of the remote files without running any tasks.
By default, Task will timeout requests to download remote files after 10 seconds
and look for a cached copy instead. This timeout can be configured by setting
the `--timeout` flag and specifying a duration. For example, `--timeout 5s` will
set the timeout to 5 seconds.

# FAQ
This page contains a list of frequently asked questions about Task.
## Why won't my task update my shell environment?
This is a limitation of how shells work. Task runs as a subprocess of your
current shell, so it can't change the environment of the shell that started it.
This limitation is shared by other task runners and build tools too.
A common way to work around this is to create a task that will generate output
that can be parsed by your shell. For example, to set an environment variable on
your shell you can write a task like this:
```yaml
my-shell-env:
cmds:
- echo "export FOO=foo"
- echo "export BAR=bar"
```
Now run `eval $(task my-shell-env)` and the variables `$FOO` and `$BAR` will be
available in your shell.
## I can't reuse my shell in a task's commands
Task runs each command as a separate shell process, so something you do in one
command won't effect any future commands. For example, this won't work:
```yaml
version: '3'
tasks:
foo:
cmds:
- a=foo
- echo $a
# outputs ""
```
To work around this you can either use a multiline command:
```yaml
version: '3'
tasks:
foo:
cmds:
- |
a=foo
echo $a
# outputs "foo"
```
Or for more complex multi-line commands it is recommended to move your code into
a separate file and call that instead:
```yaml
version: '3'
tasks:
foo:
cmds:
- ./foo-printer.bash
```
```shell
#!/bin/bash
a=foo
echo $a
```
## 'x' builtin command doesn't work on Windows
The default shell on Windows (`cmd` and `powershell`) do not have commands like
`rm` and `cp` available as builtins. This means that these commands won't work.
If you want to make your Taskfile fully cross-platform, you'll need to work
around this limitation using one of the following methods:
- Use the `{{OS}}` function to run an OS-specific script.
- Use something like `{{if eq OS "windows"}}powershell {{end}}<my_cmd>` to
detect windows and run the command in Powershell directly.
- Use a shell on Windows that supports these commands as builtins, such as [Git
Bash][git-bash] or [WSL][wsl].
We want to make improvements to this part of Task and the issues below track
this work. Constructive comments and contributions are very welcome!

# Installation
Task offers many installation methods. Check out the available methods below.
## Package Managers
### Homebrew
If you're on macOS or Linux and have [Homebrew][homebrew] installed, getting
Task is as simple as running:
```shell
brew install go-task/tap/go-task
```
The above Formula is
[maintained by ourselves](https://github.com/go-task/homebrew-tap/blob/main/Formula/go-task.rb).
Recently, Task was also made available
[on the official Homebrew repository](https://formulae.brew.sh/formula/go-task),
so you also have that option if you prefer:
```shell
brew install go-task
```
### Tea
If you're on macOS or Linux and have [tea][tea] installed, getting Task is as
simple as running:
```shell
tea task
```
or, if you have tea’s magic enabled:
```shell
task
```
This installation method is community owned. After a new release of Task, they
are automatically released by tea in a minimum of time.
### Snap
Task is available in [Snapcraft][snapcraft], but keep in mind that your Linux
distribution should allow classic confinement for Snaps to Task work right:
```shell
sudo snap install task --classic
```
### Chocolatey
If you're on Windows and have [Chocolatey][choco] installed, getting Task is as
simple as running:
```shell
choco install go-task
```
This installation method is community owned.
### Scoop
If you're on Windows and have [Scoop][scoop] installed, getting Task is as
simple as running:
```shell
scoop install task
```
This installation method is community owned. After a new release of Task, it may
take some time until it's available on Scoop.
### AUR
If you're on Arch Linux you can install Task from
[AUR](https://aur.archlinux.org/packages/go-task-bin) using your favorite
package manager such as `yay`, `pacaur` or `yaourt`:
```shell
yay -S go-task-bin
```
Alternatively, there's
[this package](https://aur.archlinux.org/packages/go-task) which installs from
the source code instead of downloading the binary from the
[releases page](https://github.com/go-task/task/releases):
```shell
yay -S go-task
```
This installation method is community owned.
### Fedora
If you're on Fedora Linux you can install Task from the official
[Fedora](https://packages.fedoraproject.org/pkgs/golang-github-task/go-task/)
repository using `dnf`:
```shell
sudo dnf install go-task
```
This installation method is community owned. After a new release of Task, it may
take some time until it's available in
[Fedora](https://packages.fedoraproject.org/pkgs/golang-github-task/go-task/).
### Nix
If you're on NixOS or have Nix installed you can install Task from
[nixpkgs](https://github.com/NixOS/nixpkgs):
```shell
nix-env -iA nixpkgs.go-task
```
This installation method is community owned. After a new release of Task, it may
take some time until it's available in
[nixpkgs](https://github.com/NixOS/nixpkgs).
### npm
You can also use Node and npm to install Task by installing
[this package](https://www.npmjs.com/package/@go-task/cli).
```shell
npm install -g @go-task/cli
```
### Winget
If you are using Windows and installed the
[winget](https://github.com/microsoft/winget-cli) package management tool, you
can install Task from [winget-pkgs](https://github.com/microsoft/winget-pkgs).
```shell
winget install Task.Task
```
## Get The Binary
### Binary
You can download the binary from the [releases page on GitHub][releases] and add
to your `$PATH`.
DEB and RPM packages are also available.
The `task_checksums.txt` file contains the SHA-256 checksum for each file.
### Install Script
We also have an [install script][installscript] which is very useful in
scenarios like CI. Many thanks to [GoDownloader][godownloader] for enabling the
easy generation of this script.
By default, it installs on the `./bin` directory relative to the working
directory:
```shell
sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d
```
It is possible to override the installation directory with the `-b` parameter.
On Linux, common choices are `~/.local/bin` and `~/bin` to install for the
current user or `/usr/local/bin` to install for all users:
```shell
sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d -b ~/.local/bin
```
:::caution
On macOS and Windows, `~/.local/bin` and `~/bin` are not added to `$PATH` by
default.
:::
### GitHub Actions
If you want to install Task in GitHub Actions you can try using
[this action](https://github.com/arduino/setup-task) by the Arduino team:
```yaml
- name: Install Task
uses: arduino/setup-task@v1
with:
version: 3.x
repo-token: ${{ secrets.GITHUB_TOKEN }}
```
This installation method is community owned.
## Build From Source
### Go Modules
Ensure that you have a supported version of [Go][go] properly installed and
setup. You can find the minimum required version of Go in the
[go.mod](https://github.com/go-task/task/blob/main/go.mod#L3) file.
You can then install the latest release globally by running:
```shell
go install github.com/go-task/task/v3/cmd/task@latest
```
Or you can install into another directory:
```shell
env GOBIN=/bin go install github.com/go-task/task/v3/cmd/task@latest
```
:::tip
For CI environments we recommend using the [install script](#install-script)
instead, which is faster and more stable, since it'll just download the latest
released binary.
:::
## Setup completions
Download the autocompletion file corresponding to your shell.
[All completions are available on the Task repository](https://github.com/go-task/task/tree/main/completion).
### Bash
First, ensure that you installed bash-completion using your package manager.
Make the completion file executable:
```shell
chmod +x path/to/task.bash
```
After, add this to your `~/.bash_profile`:
```shell
source path/to/task.bash
```
### ZSH
Put the `_task` file somewhere in your `$FPATH`:
```shell
mv path/to/_task /usr/local/share/zsh/site-functions/_task
```
Ensure that the following is present in your `~/.zshrc`:
```shell
autoload -U compinit
compinit -i
```
ZSH version 5.7 or later is recommended.
### Fish
Move the `task.fish` completion script:
```shell
mv path/to/task.fish ~/.config/fish/completions/task.fish
```
### PowerShell
Open your profile script with:
```powershell
mkdir -Path (Split-Path -Parent $profile) -ErrorAction SilentlyContinue
notepad $profile
```
Add the line and save the file:
```shell
Invoke-Expression -Command path/to/task.ps1
```

# Integrations
## Visual Studio Code Extension
Task has an
[official extension for Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=task.vscode-task).
The code for this project can be found
[here](https://github.com/go-task/vscode-task). To use this extension, you must
have Task v3.23.0+ installed on your system.
This extension provides the following features (and more):
- View tasks in the sidebar.
- Run tasks from the sidebar and command palette.
- Go to definition from the sidebar and command palette.
- Run last task command.
- Multi-root workspace support.
- Initialize a Taskfile in the current workspace.
To get autocompletion and validation for your Taskfile, see the
[Schema](#schema) section below.
![Task for Visual Studio Code](https://github.com/go-task/vscode-task/blob/main/res/preview.png?raw=true)
## Schema
This was initially created by @KROSF in
[this Gist](https://gist.github.com/KROSF/c5435acf590acd632f71bb720f685895) and
is now officially maintained in
[this file](https://github.com/go-task/task/blob/main/docs/static/schema.json)
and made available at https://taskfile.dev/schema.json. This schema can be used
to validate Taskfiles and provide autocompletion in many code editors:
### Visual Studio Code
To integrate the schema into VS Code, you need to install the
[YAML extension](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-yaml)
by Red Hat. Any `Taskfile.yml` in your project should automatically be detected
and validation/autocompletion should work. If this doesn't work or you want to
manually configure it for files with a different name, you can add the following
to your `settings.json`:
```json
// settings.json
{
"yaml.schemas": {
"https://taskfile.dev/schema.json": [
"**/Taskfile.yml",
"./path/to/any/other/taskfile.yml"
]
}
}
```
You can also configure the schema directly inside of a Taskfile by adding the
following comment to the top of the file:
```yaml
# yaml-language-server: $schema=https://taskfile.dev/schema.json
version: '3'
```
You can find more information on this in the
[YAML language server project](https://github.com/redhat-developer/yaml-language-server).
## Community Integrations
In addition to our official integrations, there is an amazing community of
developers who have created their own integrations for Task:
- [Sublime Text Plugin](https://packagecontrol.io/packages/Taskfile)
[[source](https://github.com/biozz/sublime-taskfile)] by @biozz
- [IntelliJ Plugin](https://plugins.jetbrains.com/plugin/17058-taskfile)
[[source](https://github.com/lechuckroh/task-intellij-plugin)] by @lechuckroh
- [mk](https://github.com/pycontribs/mk) command line tool recognizes Taskfiles
natively.
If you have made something that integrates with Task, please feel free to open a
PR to add it to this list.

# Task
<div align="center">
<img id="logo" src="img/logo.svg" height="250px" width="250px" />
</div>
Task is a task runner / build tool that aims to be simpler and easier to use
than, for example, [GNU Make][make].
Since it's written in [Go][go], Task is just a single binary and has no other
dependencies, which means you don't need to mess with any complicated install
setups just to use a build tool.
Once [installed](/installation), you just need to describe your build tasks
using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
```yaml title="Taskfile.yml"
version: '3'
tasks:
hello:
cmds:
- echo 'Hello World from Task!'
silent: true
```
And call it by running `task hello` from your terminal.
The above example is just the start, you can take a look at the [usage](/usage)
guide to check the full schema documentation and Task features.
## Features
- [Easy installation](/installation): just download a single binary, add to
`$PATH` and you're done! Or you can also install using [Homebrew][homebrew],
[Snapcraft][snapcraft], or [Scoop][scoop] if you want.
- Available on CIs: by adding
[this simple command](/installation#install-script) to install on your CI
script and you're ready to use Task as part of your CI pipeline;
- Truly cross-platform: while most build tools only work well on Linux or macOS,
Task also supports Windows thanks to [this shell interpreter for Go][sh].
- Great for code generation: you can easily
[prevent a task from running](/usage#prevent-unnecessary-work) if a given set
of files haven't changed since last run (based either on its timestamp or
content).

# Releasing
The release process of Task is done with the help of [GoReleaser][goreleaser].
You can test the release process locally by calling the `test-release` task of
the Taskfile.
[GitHub Actions](https://github.com/go-task/task/actions) should release
artifacts automatically when a new Git tag is pushed to `main` branch (raw
executables and DEB and RPM packages).
Since v3.15.0, raw executables can also be reproduced and verified locally by
checking out a specific tag and calling `goreleaser build`, using the Go version
defined in the above GitHub Actions.
# Homebrew
Goreleaser will automatically push a new commit to the
[Formula/go-task.rb][gotaskrb] file in the [Homebrew tap][homebrewtap]
repository to release the new version.
# npm
To release to npm update the version in the [`package.json`][packagejson] file
and then run `task npm:publish` to push it.
# Snapcraft
The [snap package][snappackage] requires to manual steps to release a new
version:
- Updating the current version on [snapcraft.yaml][snapcraftyaml].
- Moving both `amd64`, `armhf` and `arm64` new artifacts to the stable channel
on the [Snapcraft dashboard][snapcraftdashboard].
# winget
winget also requires manual steps to be completed. By running
`task goreleaser:test` locally, manifest files will be generated on
`dist/winget/manifests/t/Task/Task/v{version}`.
[Upload the manifest directory into this fork](https://github.com/go-task/winget-pkgs/tree/master/manifests/t/Task/Task)
and open a pull request into
[this repository](https://github.com/microsoft/winget-pkgs).
# Scoop
Scoop is a command-line package manager for the Windows operating system. Scoop
package manifests are maintained by the community. Scoop owners usually take
care of updating versions there by editing
[this file](https://github.com/ScoopInstaller/Main/blob/master/bucket/task.json).
If you think its Task version is outdated, open an issue to let us know.
# Nix
Nix is a community owned installation method. Nix package maintainers usually
take care of updating versions there by editing

# Style guide
This is the official style guide for `Taskfile.yml` files. It provides basic
instructions for keeping your Taskfiles clean and familiar to other users.
This guide contains general guidelines, but they do not necessarily need to be
followed strictly. Feel free to disagree and do things differently if you need
or want to. Any improvements to this guide are welcome! Please open an issue or
create a pull request to contribute.
## Use the suggested ordering of the main sections
```yaml
version:
includes:
# optional configurations (output, silent, method, run, etc.)
vars:
env: # followed or replaced by dotenv
tasks:
```
## Use two spaces for indentation
This is the most common convention for YAML files, and Task follows it.
```yaml
# bad
tasks:
foo:
cmds:
- echo 'foo'
# good
tasks:
foo:
cmds:
- echo 'foo'
```
## Separate the main sections with empty lines
```yaml
# bad
version: '3'
includes:
docker: ./docker/Taskfile.yml
output: prefixed
vars:
FOO: bar
env:
BAR: baz
tasks:
# ...
# good
version: '3'
includes:
docker: ./docker/Taskfile.yml
output: prefixed
vars:
FOO: bar
env:
BAR: baz
tasks:
# ...
```
## Separate tasks with empty lines
```yaml
# bad
version: '3'
tasks:
foo:
cmds:
- echo 'foo'
bar:
cmds:
- echo 'bar'
baz:
cmds:
- echo 'baz'
# good
version: '3'
tasks:
foo:
cmds:
- echo 'foo'
bar:
cmds:
- echo 'bar'
baz:
cmds:
- echo 'baz'
```
## Use only uppercase letters for variable names
```yaml
# bad
version: '3'
vars:
binary_name: myapp
tasks:
build:
cmds:
- go build -o {{.binary_name}} .
# good
version: '3'
vars:
BINARY_NAME: myapp
tasks:
build:
cmds:
- go build -o {{.BINARY_NAME}} .
```
## Avoid using whitespace when templating variables
```yaml
# bad
version: '3'
tasks:
greet:
cmds:
- echo '{{ .MESSAGE }}'
# good
version: '3'
tasks:
greet:
cmds:
- echo '{{.MESSAGE}}'
```
This convention is also commonly used in templates for the Go programming
language.
## Use kebab case for task names
```yaml
# bad
version: '3'
tasks:
do_something_fancy:
cmds:
- echo 'Do something'
# good
version: '3'
tasks:
do-something-fancy:
cmds:
- echo 'Do something'
```
## Use a colon to separate the task namespace and name
```yaml
# good
version: '3'
tasks:
docker:build:
cmds:
- docker ...
docker:run:
cmds:
- docker-compose ...
```
This is also done automatically when using included Taskfiles.
## Prefer using external scripts instead of multi-line commands
```yaml
# bad
version: '3'
tasks:
build:
cmds:
- |
for i in $(seq 1 10); do
echo $i
echo "some other complex logic"
done'
# good
version: '3'
tasks:
build:
cmds:
- ./scripts/my_complex_script.sh
```

# Taskfile Versions
The Taskfile syntax and features changed with time. This document explains what
changed on each version and how to upgrade your Taskfile.
## What the Taskfile version mean
The Taskfile version follows the Task version. E.g. the change to Taskfile
version `2` means that Task `v2.0.0` should be release to support it.
The `version:` key on Taskfile accepts a semver string, so either `2`, `2.0` or
`2.0.0` is accepted. If you choose to use `2.0` Task will not enable future
`2.1` features, but if you choose to use `2`, then any `2.x.x` features will be
available, but not `3.0.0+`.
## Version 3 ![latest](https://img.shields.io/badge/latest-brightgreen)
These are some major changes done on `v3`:
- Task's output will now be colored
- Added support for `.env` like files
- Added `label:` setting to task so one can override how the task name appear in
the logs
- A global `method:` was added to allow setting the default method, and Task's
default changed to `checksum`
- Two magic variables were added when using `status:`: `CHECKSUM` and
`TIMESTAMP` which contains, respectively, the XXH3 checksum and greatest
modification timestamp of the files listed on `sources:`
- Also, the `TASK` variable is always available with the current task name
- CLI variables are always treated as global variables
- Added `dir:` option to `includes` to allow choosing on which directory an
included Taskfile will run:
```yaml
includes:
docs:
taskfile: ./docs
dir: ./docs
```
- Implemented short task syntax. All below syntaxes are equivalent:
```yaml
version: '3'
tasks:
print:
cmds:
- echo "Hello, World!"
```
```yaml
version: '3'
tasks:
print:
- echo "Hello, World!"
```
```yaml
version: '3'
tasks:
print: echo "Hello, World!"
```
- There was a major refactor on how variables are handled. They're now easier to
understand. The `expansions:` setting was removed as it became unnecessary.
This is the order in which Task will process variables, each level can see the
variables set by the previous one and override those.
- Environment variables
- Global + CLI variables
- Call variables
- Task variables
## Version 2.6
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
Version 2.6 comes with `preconditions` stanza in tasks.
```yaml
version: '2'
tasks:
upload_environment:
preconditions:
- test -f .env
cmds:
- aws s3 cp .env s3://myenvironment
```
Please check the [documentation][includes]
## Version 2.2
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
Version 2.2 comes with a global `includes` options to include other Taskfiles:
```yaml
version: '2'
includes:
docs: ./documentation # will look for ./documentation/Taskfile.yml
docker: ./DockerTasks.yml
```
## Version 2.1
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
Version 2.1 includes a global `output` option, to allow having more control over
how commands output are printed to the console (see [documentation][output] for
more info):
```yaml
version: '2'
output: prefixed
tasks:
server:
cmds:
- go run main.go
prefix: server
```
From this version it's also possible to ignore errors of a command or task
(check documentation [here][ignore_errors]):
```yaml
version: '2'
tasks:
example-1:
cmds:
- cmd: exit 1
ignore_error: true
- echo "This will be print"
example-2:
cmds:
- exit 1
- echo "This will be print"
ignore_error: true
```
## Version 2.0
:::caution
v2 schemas are [no longer supported by the latest version of
Task][deprecate-version-2-schema].
:::
At version 2, we introduced the `version:` key, to allow us to evolve Task with
new features without breaking existing Taskfiles. The new syntax is as follows:
```yaml
version: '2'
tasks:
echo:
cmds:
- echo "Hello, World!"
```
Version 2 allows you to write global variables directly in the Taskfile, if you
don't want to create a `Taskvars.yml`:
```yaml
version: '2'
vars:
GREETING: Hello, World!
tasks:
greet:
cmds:
- echo "{{.GREETING}}"
```
The variable priority order changed to the following:
1. Task variables
2. Call variables
3. Taskfile variables
4. Taskvars file variables
5. Environment variables
A new global option was added to configure the number of variables expansions
(which default to 2):
```yaml
version: '2'
expansions: 3
vars:
FOO: foo
BAR: bar
BAZ: baz
FOOBAR: '{{.FOO}}{{.BAR}}'
FOOBARBAZ: '{{.FOOBAR}}{{.BAZ}}'
tasks:
default:
cmds:
- echo "{{.FOOBARBAZ}}"
```
## Version 1
:::caution
v1 schema support was removed in Task >= v3.0.0.
:::
In the first version of the `Taskfile`, the `version:` key was not available,
because the tasks was in the root of the YAML document. Like this:
```yaml
echo:
cmds:
- echo "Hello, World!"
```
The variable priority order was also different:
1. Call variables
2. Environment
3. Task variables
4. `Taskvars.yml` variables
