-# Changelog
-
-## v3.3.0 - 2021-03-20
-
-- Add support for delegating CLI arguments to commands with `--` and a
-  special `CLI_ARGS` variable
-  ([#327](https://github.com/go-task/task/issues/327)).
-- Add a `--concurrency` (alias `-C`) flag, to limit the number of tasks that
-  run concurrently. This is useful for heavy workloads.
-  ([#345](https://github.com/go-task/task/pull/345)).
-
-## v3.2.2 - 2021-01-12
-
-- Improve performance of `--list` and `--summary` by skipping running shell
-  variables for these flags
-  ([#332](https://github.com/go-task/task/issues/332)).
-- Fixed a bug where an environment in a Taskfile was not always overridable
-  by the system environment
-  ([#425](https://github.com/go-task/task/issues/425)).
-- Fixed environment from .env files not being available as variables
-  ([#379](https://github.com/go-task/task/issues/379)).
-- The install script is now working for ARM platforms
-  ([#428](https://github.com/go-task/task/pull/428)).
-
-## v3.2.1 - 2021-01-09
-
-- Fixed some bugs and regressions regarding dynamic variables and directories
-  ([#426](https://github.com/go-task/task/issues/426)).
-- The [slim-sprig](https://github.com/go-task/slim-sprig) package was updated
-  with the upstream [sprig](https://github.com/Masterminds/sprig).
-
-## v3.2.0 - 2021-01-07
-
-- Fix the `.task` directory being created in the task directory instead of the
-  Taskfile directory
-  ([#247](https://github.com/go-task/task/issues/247)).
-- Fix a bug where dynamic variables (those declared with `sh:`) were not
-  running in the task directory when the task has a custom dir or it was
-  in an included Taskfile
-  ([#384](https://github.com/go-task/task/issues/384)).
-- The watch feature (via the `--watch` flag) got a few different bug fixes and
-  should be more stable now
-  ([#423](https://github.com/go-task/task/pull/423), [#365](https://github.com/go-task/task/issues/365)).
-
-## v3.1.0 - 2021-01-03
-
-- Fix a bug when the checksum up-to-date resolution is used by a task
-  with a custom `label:` attribute
-  ([#412](https://github.com/go-task/task/issues/412)).
-- Starting from this release, we're releasing official ARMv6 and ARM64 binaries
-  for Linux
-  ([#375](https://github.com/go-task/task/issues/375), [#418](https://github.com/go-task/task/issues/418)).
-- Task now respects the order of declaration of included Taskfiles when
-  evaluating variables declaring by them
-  ([#393](https://github.com/go-task/task/issues/393)).
-- `set -e` is now automatically set on every command. This was done to fix an
-  issue where multiline string commands wouldn't really fail unless the
-  sentence was in the last line
-  ([#403](https://github.com/go-task/task/issues/403)).
-
-## v3.0.1 - 2020-12-26
-
-- Allow use as a library by moving the required packages out of the `internal`
-  directory
-  ([#358](https://github.com/go-task/task/pull/358)).
-- Do not error if a specified dotenv file does not exist
-  ([#378](https://github.com/go-task/task/issues/378), [#385](https://github.com/go-task/task/pull/385)).
-- Fix panic when you have empty tasks in your Taskfile
-  ([#338](https://github.com/go-task/task/issues/338), [#362](https://github.com/go-task/task/pull/362)).
-
-## v3.0.0 - 2020-08-16
-
-- On `v3`, all CLI variables will be considered global variables
-  ([#336](https://github.com/go-task/task/issues/336), [#341](https://github.com/go-task/task/pull/341))
-- Add support to `.env` like files
-  ([#324](https://github.com/go-task/task/issues/324), [#356](https://github.com/go-task/task/pull/356)).
-- Add `label:` to task so you can override the task name in the logs
-  ([#321](https://github.com/go-task/task/issues/321]), [#337](https://github.com/go-task/task/pull/337)).
-- Refactor how variables work on version 3
-  ([#311](https://github.com/go-task/task/pull/311)).
-- Disallow `expansions` on v3 since it has no effect.
-- `Taskvars.yml` is not automatically included anymore.
-- `Taskfile_{{OS}}.yml` is not automatically included anymore.
-- Allow interpolation on `includes`, so you can manually include a Taskfile
-  based on operation system, for example.
-- Expose `.TASK` variable in templates with the task name
-  ([#252](https://github.com/go-task/task/issues/252)).
-- Implement short task syntax
-  ([#194](https://github.com/go-task/task/issues/194), [#240](https://github.com/go-task/task/pull/240)).

-  ([#260](https://github.com/go-task/task/issues/260), [#144](https://github.com/go-task/task/issues/144))
-- Taskfiles in version 1 are not supported anymore
-  ([#237](https://github.com/go-task/task/pull/237)).
-- Added global `method:` option. With this option, you can set a default
-  method to all tasks in a Taskfile
-  ([#246](https://github.com/go-task/task/issues/246)).
-- Changed default method from `timestamp` to `checksum`
-  ([#246](https://github.com/go-task/task/issues/246)).
-- 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](https://github.com/go-task/task/pull/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
-  reduction of about 22%
-  ([#219](https://github.com/go-task/task/pull/219)).
-- We now use some colors on Task output to better distinguish message types -
-  commands are green, errors are red, etc
-  ([#207](https://github.com/go-task/task/pull/207)).
-
-## v2.8.1 - 2020-05-20
-
-- Fix error code for the `--help` flag
-  ([#300](https://github.com/go-task/task/issues/300), [#330](https://github.com/go-task/task/pull/330)).
-- Print version to stdout instead of stderr
-  ([#299](https://github.com/go-task/task/issues/299), [#329](https://github.com/go-task/task/pull/329)).
-- Supress `context` errors when using the `--watch` flag
-  ([#313](https://github.com/go-task/task/issues/313), [#317](https://github.com/go-task/task/pull/317)).
-- Support templating on description
-  ([#276](https://github.com/go-task/task/issues/276), [#283](https://github.com/go-task/task/pull/283)).
-
-## v2.8.0 - 2019-12-07
-
-- Add `--parallel` flag (alias `-p`) to run tasks given by the command line in
-  parallel
-  ([#266](https://github.com/go-task/task/pull/266)).

-  execute the `default` task.

-  Taskfile.
-
-## v2.7.1 - 2019-11-10
-
-- Fix error being raised when `exit 0` was called

-
-- Fixed panic bug when assigning a global variable
-  ([#229](https://github.com/go-task/task/issues/229), [#243](https://github.com/go-task/task/issues/234)).

-  ([#228](https://github.com/go-task/task/pull/228), [#238](https://github.com/go-task/task/issues/238)).
-
-## v2.6.0 - 2019-07-21

-- Add `preconditions:` to task
-  ([#205](https://github.com/go-task/task/pull/205)).

-  ([#209](https://github.com/go-task/task/issues/209), [#211](https://github.com/go-task/task/pull/211)).
-- We now have a `--taskfile` flag (alias `-t`), which can be used to run
-  another Taskfile (other than the default `Taskfile.yml`)
-  ([#221](https://github.com/go-task/task/pull/221)).
-- It's now possible to install Task using Homebrew on Linux

+## Installation
+
+### Go
+
+If you have a [Golang][golang] environment setup, you can simply run:
+
+```bash
+go get -u -v github.com/go-task/task/cmd/task
+```
+
+### Homebrew
+
+If you're on macOS and have [Homebrew][homebrew] installed, getting Task is
+as simple as running:
+
+```bash
+brew update
+brew tap go-task/tap
+brew install go-task
+```
+
+### Snap
+
+Task is available for [Snapcraft][snapcraft], but keep in mind that your
+Linux distribution should allow classic confinement for Snaps to Task work
+right:
+
+```bash
+sudo snap install task
+```
+
+### Binary
+
+Or you can download the binary from the [releases][releases] page and add to
+your `PATH`. DEB and RPM packages are also available.
+The `task_checksums.txt` file contains the sha256 checksum for each file.
+
+## Usage
+
+Create a file called `Taskfile.yml` in the root of the project.
+The `cmds` attribute should contains the commands of a task.
+The example below allows compile a Go app and uses [Minify][minify] to concat
+and minify multiple CSS files into a single one.
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build -v -i main.go
+
+  assets:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+Running the tasks is as simple as running:
+
+```bash
+task assets build
+```
+
+Task uses [github.com/mvdan/sh](https://github.com/mvdan/sh), a native Go sh
+interpreter. So you can write sh/bash commands and it will work even on
+Windows, where `sh` or `bash` is usually not available. Just remember any
+executable called must be available by the OS or in PATH.
+
+If you ommit a task name, "default" will be assumed.
+
+### Environment
+
+You can specify environment variables that are added when running a command:
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo $hallo
+    env:
+      hallo: welt
+```
+
+### OS specific task
+
+If you add a `Taskfile_{{GOOS}}.yml` you can override or amend your taskfile
+based on the operating system.
+
+Example:
+
+Taskfile.yml:
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo "default"
+```
+
+Taskfile_linux.yml:
+
+```yml
+tasks:
+  build:
+    cmds:
+      - echo "linux"
+```
+
+Will print out `linux` and not default.
+
+It's also possible to have OS specific `Taskvars.yml` file, like
+`Taskvars_windows.yml`, `Taskfile_linux.yml` or `Taskvars_darwin.yml`. See the
+[variables section](#variables) below.
+
+### Task directory
+
+By default, tasks will be executed in the directory where the Taskfile is
+located. But you can easily make the task run in another folder informing
+`dir`:
+
+```yml
+version: '2'
+
+tasks:
+  serve:
+    dir: public/www
+    cmds:
+      # run http server
+      - caddy
+```
+
+### Task dependencies
+
+You may have tasks that depends on others. Just pointing them on `deps` will
+make them run automatically before running the parent task:
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    deps: [assets]
+    cmds:
+      - go build -v -i main.go
+
+  assets:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+In the above example, `assets` will always run right before `build` if you run
+`task build`.
+
+A task can have only dependencies and no commands to group tasks together:
+
+```yml
+version: '2'
+
+tasks:
+  assets:
+    deps: [js, css]
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+If there are more than one dependency, they always run in parallel for better
+performance.
+
+If you want to pass information to dependencies, you can do that the same
+manner as you would to [call another task](#calling-another-task):
+
+```yml
+version: '2'
+
+tasks:
+  default:
+    deps:
+      - task: echo_sth
+        vars: {TEXT: "before 1"}
+      - task: echo_sth
+        vars: {TEXT: "before 2"}
+    cmds:
+      - echo "after"
+
+  echo_sth:
+    cmds:
+      - echo {{.TEXT}}
+```
+
+### Calling another task
+
+When a task has many dependencies, they are executed concurrently. This will
+often result in a faster build pipeline. But in some situations you may need
+to call other tasks serially. In this case, just use the following syntax:
+
+```yml
+version: '2'
+
+tasks:
+  main-task:
+    cmds:
+      - task: task-to-be-called
+      - task: another-task
+      - echo "Both done"
+
+  task-to-be-called:
+    cmds:
+      - echo "Task to be called"
+
+  another-task:
+    cmds:
+      - echo "Another task"
+```
+
+Overriding variables in the called task is as simple as informing `vars`
+attribute:
+
+```yml
+version: '2'
+
+tasks:
+  main-task:
+    cmds:
+      - task: write-file
+        vars: {FILE: "hello.txt", CONTENT: "Hello!"}
+      - task: write-file
+        vars: {FILE: "world.txt", CONTENT: "World!"}
+
+  write-file:
+    cmds:
+      - echo "{{.CONTENT}}" > {{.FILE}}
+```
+
+The above syntax is also supported in `deps`.
+
+### Prevent unnecessary work
+
+If a task generates something, you can inform Task the source and generated
+files, so Task will prevent to run them if not necessary.
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    deps: [js, css]
+    cmds:
+      - go build -v -i main.go
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+    sources:
+      - src/js/**/*.js
+    generates:
+      - public/script.js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+    sources:
+      - src/css/**/*.css
+    generates:
+      - public/style.css
+```
+
+`sources` and `generates` can be files or file patterns. When both are given,
+Task will compare the modification date/time of the files to determine if it's
+necessary to run the task. If not, it will just print a message like
+`Task "js" is up to date`.
+
+If you prefer this check to be made by the content of the files, instead of
+its timestamp, just set the `method` property to `checksum`.
+You will probably want to ignore the `.task` folder in your `.gitignore` file
+(It's there that Task stores the last checksum).
+This feature is still experimental and can change until it's stable.
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build .
+    sources:
+      - ./*.go
+    generates:
+      - app{{exeExt}}
+    method: checksum
+```
+
+> TIP: method `none` skips any validation and always run the task.
+
+Alternatively, you can inform a sequence of tests as `status`. If no error
+is returned (exit status 0), the task is considered up-to-date:
+
+```yml
+version: '2'
+
+tasks:
+  generate-files:
+    cmds:
+      - mkdir directory
+      - touch directory/file1.txt
+      - touch directory/file2.txt
+    # test existence of files
+    status:
+      - test -d directory
+      - test -f directory/file1.txt
+      - test -f directory/file2.txt
+```
+
+You can use `--force` or `-f` if you want to force a task to run even when
+up-to-date.
+
+Also, `task --status [tasks]...` will exit with non-zero exit code if any of
+the tasks is not up-to-date.
+
+### Variables
+
+When doing interpolation of variables, Task will look for the below.
+They are listed below in order of importance (e.g. most important first):
+
+- Variables declared locally in the task
+- Variables given while calling a task from another.
+  (See [Calling another task](#calling-another-task) above)
+- Variables declared in the `vars:` option in the `Taskfile`
+- Variables available in the `Taskvars.yml` file
+- Environment variables
+
+Example of sending parameters with environment variables:
+
+```bash
+$ TASK_VARIABLE=a-value task do-something
+```
+
+Since some shells don't support above syntax to set environment variables
+(Windows) tasks also accepts a similar style when not in the beginning of
+the command. Variables given in this form are only visible to the task called
+right before.
+
+```bash
+$ task write-file FILE=file.txt "CONTENT=Hello, World!" print "MESSAGE=All done!"
+```
+
+Example of locally declared vars:
+
+```yml
+version: '2'
+
+tasks:
+  print-var:
+    cmds:
+      echo "{{.VAR}}"
+    vars:
+      VAR: Hello!
+```
+
+Example of global vars in a `Taskfile.yml`:
+
+```yml
+version: '2'
+
+vars:
+  GREETING: Hello from Taskfile!
+
+tasks:
+  greet:
+    cmds:
+      - echo "{{.GREETING}}"
+```
+
+Example of `Taskvars.yml` file:
+
+```yml
+PROJECT_NAME: My Project
+DEV_MODE: production
+GIT_COMMIT: {sh: git log -n 1 --format=%h}
+```
+
+#### Variables expansion
+
+Variables are expanded 2 times by default. You can change that by setting the
+`expansions:` option. Change that will be necessary if you compose many
+variables together:
+
+```yml
+version: '2'
+
+expansions: 3
+
+vars:
+  FOO: foo
+  BAR: bar
+  BAZ: baz
+  FOOBAR: "{{.FOO}}{{.BAR}}"
+  FOOBARBAZ: "{{.FOOBAR}}{{.BAZ}}"
+
+tasks:
+  default:
+    cmds:
+      - echo "{{.FOOBARBAZ}}"
+```
+
+#### Dynamic variables
+
+The below syntax (`sh:` prop in a variable) is considered a dynamic variable.
+The value will be treated as a command and the output assigned. If there is one
+or more trailing newlines, the last newline will be trimmed.
+
+```yml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build -ldflags="-X main.Version={{.GIT_COMMIT}}" main.go
+    vars:
+      GIT_COMMIT:
+        sh: git log -n 1 --format=%h
+```
+
+This works for all types of variables.
+
+### Go's template engine
+
+Task parse commands as [Go's template engine][gotemplate] before executing
+them. Variables are accessible through dot syntax (`.VARNAME`).
+
+All functions by the Go's [sprig lib](http://masterminds.github.io/sprig/)
+are available. The following example gets the current date in a given format:
+
+```yml
+version: '2'
+
+tasks:
+  print-date:
+    cmds:
+      - echo {{now | date "2006-01-02"}}
+```
+
+Task also adds the following functions:
+
+- `OS`: Returns operating system. Possible values are "windows", "linux",
+  "darwin" (macOS) and "freebsd".
+- `ARCH`: return the architecture Task was compiled to: "386", "amd64", "arm"
+  or "s390x".
+- `splitLines`: Splits Unix (\n) and Windows (\r\n) styled newlines.
+- `catLines`: Replaces Unix (\n) and Windows (\r\n) styled newlines with a space.
+- `toSlash`: Does nothing on Unix, but on Windows converts a string from `\`
+  path format to `/`.
+- `fromSlash`: Oposite of `toSlash`. Does nothing on Unix, but on Windows
+  converts a string from `\` path format to `/`.
+- `exeExt`: Returns the right executable extension for the current OS
+  (`".exe"` for Windows, `""` for others).
+
+Example:
+
+```yml
+version: '2'
+
+tasks:
+  print-os:
+    cmds:
+      - echo '{{OS}} {{ARCH}}'
+      - echo '{{if eq OS "windows"}}windows-command{{else}}unix-command{{end}}'
+      # This will be path/to/file on Unix but path\to\file on Windows
+      - echo '{{fromSlash "path/to/file"}}'
+  enumerated-file:
+    vars:
+      CONTENT: |
+        foo
+        bar
+    cmds:
+      - |
+        cat << EOF > output.txt
+        {{range $i, $line := .CONTENT | splitLines -}}
+        {{printf "%3d" $i}}: {{$line}}
+        {{end}}EOF
+```
+
+### Help
+
+Running `task --list` (or `task -l`) lists all tasks with a description.
+The following taskfile:
+
+```yml

+```
+
+would print the following output:
+
+```bash
+* build:   Build the go binary.
+* test:    Run all the go tests.
+```
+
+## Silent mode
+
+Silent mode disables echoing of commands before Task runs it.
+For the following Taskfile:
+
+```yml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "Print something"
+```
+
+Normally this will be print:
+
+```sh
+echo "Print something"
+Print something
+```
+
+With silent mode on, the below will be print instead:
+
+```sh
+Print something
+```
+
+There's three ways to enable silent mode:
+
+* At command level:
+
+```yml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - cmd: echo "Print something"
+        silent: true
+```
+
+* At task level:
+
+```yml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "Print something"
+    silent: true
+```
+
+* Or globally with `--silent` or `-s` flag
+
+If you want to suppress stdout instead, just redirect a command to `/dev/null`:
+
+```yml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "This will print nothing" > /dev/null
+```
+
+## Watch tasks (experimental)
+
+If you give a `--watch` or `-w` argument, task will watch for files changes
+and run the task again. This requires the `sources` attribute to be given,
+so task know which files to watch.
+
+## Examples
+
+The [go-task/examples][examples] intends to be a collection of Taskfiles for
+various use cases.
+(It still lacks many examples, though. Contributions are welcome).

TASKFILE_VERSIONS.md

+# Taskfile version
+
+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. You you choose to use `2.0` Task will not enable future
+`2.1` features, but if you choose to use `2`, than any `2.x.x` features will be
+available, but not `3.0.0+`.
+
+## Version 1
+
+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:
+
+```yml
+echo:
+  cmds:
+    - echo "Hello, World!"
+```
+
+The variable priority order was also different:
+
+1. Call variables
+2. Environment
+3. Task variables
+4. `Taskvars.yml` variables
+
+## Version 2.0
+
+At version 2, we introduced the `version:` key, to allow us to envolve Task
+with new features without breaking existing Taskfiles. The new syntax is as
+follows:
+
+```yml
+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`:
+
+```yml
+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):
+
+```yml
+version: '2'
+
+expansions: 3
+
+vars:
+  FOO: foo
+  BAR: bar
+  BAZ: baz
+  FOOBAR: "{{.FOO}}{{.BAR}}"
+  FOOBARBAZ: "{{.FOOBAR}}{{.BAZ}}"
+
+tasks:
+  default:
+    cmds:
+      - echo "{{.FOOBARBAZ}}"

-# Task

-</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.md), you just need to describe your build tasks
-using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
-
-```yaml
-version: '3'
-
-tasks:
-  hello:
-    cmds:
-      - echo 'Hello World from Task!'
-    silent: true
-```
-
-And call it by running `task hello` from you terminal.
-
-The above example is just the start, you can take a look at the [usage](usage.md)
-guide to check the full schema documentation and Task features.
-
-## Features
-
-- [Easy installation](installation.md): 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.md#install-script)
-  to install on your CI script and you're done 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 awesome shell interpreter for Go][sh];
-- Great for code generation: you can easily [prevent a task from running](usage.md#prevent-unnecessary-work)
-  if a given set of files haven't changed since last run (based either on its
-  timestamp or content).
-

-[go]: https://golang.org/
-[yaml]: http://yaml.org/
-[homebrew]: https://brew.sh/

-# Installation
-
-Task offers many installation methods. Check out the available methods below.
-
-## Package Managers
-
-<!-- tabs:start -->
-
-#### **Homebrew**
-
-If you're on macOS or Linux and have [Homebrew][homebrew] installed, getting
-Task is as simple as running:
-
-```bash
-brew install go-task/tap/go-task
-```
-
-#### **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:
-
-```bash
-sudo snap install task --classic
-```
-
-#### **Scoop**
-
-If you're on Windows and have [Scoop][scoop] installed, use `extras` bucket
-to install Task like:
-
-```cmd
-scoop bucket add extras
-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/taskfile-git) using your favorite
-package manager such as `yay`, `pacaur` or `yaourt`:
-
-```cmd
-yay -S taskfile-git
-```
-
-This installation method is community owned, but since it's `-git` version of
-the package, it's always latest available version based on the Git repository.
-
-<!-- tabs:end -->
-
-## Get The Binary
-
-<!-- tabs:start -->
-
-#### **Binary**
-
-You can download the binary from the [releases page on GitHub][releases] and
-add to your `$PATH`.
-
-DEB and RPM packages are also available.
-
-The `task_checksums.txt` file contains the SHA-256 checksum for each file.
-
-#### **Install Script**
-
-We also have a [install script][installscript], which is very useful on
-scenarios like CIs. Many thanks to [GoDownloader][godownloader] for allowing
-easily generating this script.
-
-```bash
-# For Default Installion to ./bin with debug logging
-sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d
-
-# For Installation To /usr/local/bin for userwide access with debug logging
-# May require sudo sh
-sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d -b /usr/local/bin
-
-```
-
-> This method will download the binary on the local `./bin` directory by default.
-
-#### **GitHub Actions**
-
-If you want to install Task in GitHub Actions you can try using
-[this action](https://github.com/arduino/actions/tree/master/setup-taskfile)
-by the Arduino team:
-
-```yaml
-- name: Install Task
-  uses: Arduino/actions/setup-taskfile@master
-```
-
-This installation method is community owned.
-
-<!-- tabs:end -->
-
-## Build From Source
-
-<!-- tabs:start -->
-
-#### **Go Modules**
-
-First, make sure you have [Go][go] properly installed and setup.
-
-You can easily install it globally by running:
-
-```bash
-go get -u github.com/go-task/task/v3/cmd/task
-```
-
-Or you can install into another directory:
-
-```bash
-git clone https://github.com/go-task/task
-cd task
-
-# Compiling binary to $GOPATH/bin
-go install -v ./cmd/task
-
-# Compiling it to another location.
-# Use -o ./task.exe on Windows.
-go build -v -o ./task ./cmd/task
-```
-
-> For CI environments we recommend using the [Install Script](#get-the-binary)
-> instead, which is faster and more stable, since it'll just download the latest
-> released binary, instead of compiling the edge (master branch) version.

-# Styleguide
-
-This is the official Task styleguide for `Taskfile.yml` files. This guide
-contains some basic instructions to keep your Taskfile clean and familiar to
-other users.
-
-This contains general guidelines, but don't necessarely need to be strictly
-followed. Feel free to disagree and proceed differently in some point if you
-need or want to. Also, feel free to open issues or pull requests with
-improvements to this guide.
-
-## Use `Taskfile.yml` and not `taskfile.yml`
-
-```yaml
-# bad
-taskfile.yml
-
-
-# good
-Taskfile.yml
-```
-
-This is important especially for Linux users. Windows and macOS have case
-insensitive filesystems, so `taskfile.yml` will end up working, even that not
-officially supported. On Linux, only `Taskfile.yml` will work, though.
-
-## Use the correct order of keywords
-
-- `version:`
-- `includes:`
-- Configuration ones, like `output:`, `expansions:` or `silent:`
-- `vars:`
-- `env:`
-- `tasks:`
-
-## Use 2 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 with spaces the mains sections
-
-```yaml
-# bad
-version: '3'
-includes:
-  docker: ./docker/Taskfile.yml
-output: prefixed
-expansions: 3
-vars:
-  FOO: bar
-env:
-  BAR: baz
-tasks:
-  # ...
-
-
-# good
-version: '3'
-
-includes:
-  docker: ./docker/Taskfile.yml
-
-output: prefixed
-expansions: 3
-
-vars:
-  FOO: bar
-
-env:
-  BAR: baz
-
-tasks:
-  # ...
-```
-
-## Add spaces between tasks
-
-```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 upper-case 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}} .
-```
-
-## Don't wrap vars in spaces when templating
-
-```yaml
-# bad
-version: '3'
-
-tasks:
-  greet:
-    cmds:
-      - echo '{{ .MESSAGE }}'
-
-
-# good
-version: '3'
-
-tasks:
-  greet:
-    cmds:
-      - echo '{{.MESSAGE}}'
-```
-
-This convention is also used by most people for any Go templating.
-
-## Separate task name words with a dash
-
-```yaml
-# bad
-version: '3'
-
-tasks:
-  do_something_fancy:
-    cmds:
-      - echo 'Do something'
-
-
-# good
-version: '3'
-
-tasks:
-  do-something-fancy:
-    cmds:
-      - echo 'Do something'
-```
-
-## Use colon for task namespacing
-
-```yaml
-# good
-version: '3'
-
-tasks:
-  docker:build:
-    cmds:
-      - docker ...
-
-  docker:run:
-    cmds:
-      - docker-compose ...
-```
-
-This is also done automatically when using included Taskfiles.

-# 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 1
-
-> NOTE: Taskfiles in version 1 are not supported on Task >= v3.0.0 anymore.
-
-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
-
-## Version 2.0
-
-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 2.1
-
-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 2.2
-
-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 2.6
-
-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]
-
-[output]: usage.md#output-syntax
-[ignore_errors]: usage.md#ignore-errors
-[includes]: usage.md#including-other-taskfiles
-
-## Version 3
-
-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 md5 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 unncessary.
-  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

-# Usage
-
-## Getting started
-
-Create a file called `Taskfile.yml` in the root of your project.
-The `cmds` attribute should contain the commands of a task.
-The example below allows compiling a Go app and uses [Minify][minify] to concat
-and minify multiple CSS files into a single one.
-
-```yaml
-version: '3'
-
-tasks:
-  build:
-    cmds:
-      - go build -v -i main.go
-
-  assets:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-Running the tasks is as simple as running:
-
-```bash
-task assets build
-```
-
-Task uses [github.com/mvdan/sh](https://github.com/mvdan/sh), a native Go sh
-interpreter. So you can write sh/bash commands and it will work even on
-Windows, where `sh` or `bash` are usually not available. Just remember any
-executable called must be available by the OS or in PATH.
-
-If you omit a task name, "default" will be assumed.
-
-## Environment variables
-
-### Task
-
-You can use `env` to set custom environment variables for a specific task:
-
-```yaml
-version: '3'
-
-tasks:
-  greet:
-    cmds:
-      - echo $GREETING
-    env:
-      GREETING: Hey, there!
-```
-
-Additionally, you can set globally environment variables, that'll be available
-to all tasks:
-
-```yaml
-version: '3'
-
-env:
-  GREETING: Hey, there!
-
-tasks:
-  greet:
-    cmds:
-      - echo $GREETING
-```
-
-> NOTE: `env` supports expansion and retrieving output from a shell command
-> just like variables, as you can see on the [Variables](#variables) section.
-
-### .env files
-
-You can also ask Task to include `.env` like files by using the `dotenv:`
-setting:
-
-```
-# .env
-KEYNAME=VALUE
-```
-
-
-```yaml
-# Taskfile.yml
-
-version: '3'
-
-dotenv: ['.env']
-
-tasks:
-  greet:
-    cmds:
-      - echo "Using $KEYNAME"
-```
-
-## Including other Taskfiles
-
-If you want to share tasks between different projects (Taskfiles), you can use
-the importing mechanism to include other Taskfiles using the `includes` keyword:
-
-```yaml
-version: '3'
-
-includes:
-  docs: ./documentation # will look for ./documentation/Taskfile.yml
-  docker: ./DockerTasks.yml
-```
-
-The tasks described in the given Taskfiles will be available with the informed
-namespace. So, you'd call `task docs:serve` to run the `serve` task from
-`documentation/Taskfile.yml` or `task docker:build` to run the `build` task
-from the `DockerTasks.yml` file.
-
-### OS-specific Taskfiles
-
-With `version: '2'`, task automatically includes any `Taskfile_{{OS}}.yml`
-if it exists (for example: `Taskfile_windows.yml`, `Taskfile_linux.yml` or
-`Taskfile_darwin.yml`). Since this behavior was a bit too implicit, it
-was removed on version 3, but you still can have a similar behavior by
-explicitly importing these files:
-
-```yaml
-version: '3'
-
-includes:
-  build: ./Taskfile_{{OS}}.yml
-```
-
-### Directory of included Taskfile
-
-By default, included Taskfile's tasks are ran in the current directory, even
-if the Taskfile is in another directory, but you can force its tasks to run
-in another directory by using this alternative syntax:
-
-```yaml
-version: '3'
-
-includes:
-  docs:
-    taskfile: ./docs/Taskfile.yml
-    dir: ./docs
-```
-
-> The included Taskfiles must be using the same schema version the main
-> Taskfile uses.
-
-> Also, for now included Taskfiles can't include other Taskfiles.
-> This was a deliberate decision to keep use and implementation simple.
-> If you disagree, open an GitHub issue and explain your use case. =)
-
-## Task directory
-
-By default, tasks will be executed in the directory where the Taskfile is
-located. But you can easily make the task run in another folder informing
-`dir`:
-
-```yaml
-version: '3'
-
-tasks:
-  serve:
-    dir: public/www
-    cmds:
-      # run http server
-      - caddy
-```
-
-If the directory doesn't exist, `task` creates it.
-
-## Task dependencies
-
-> Dependencies run in parallel, so dependencies of a task shouldn't depend one
-> another. If you want to force tasks to run serially take a look at the
-> [Calling Another Task](#calling-another-task) section below.
-
-You may have tasks that depend on others. Just pointing them on `deps` will
-make them run automatically before running the parent task:
-
-```yaml
-version: '3'
-
-tasks:
-  build:
-    deps: [assets]
-    cmds:
-      - go build -v -i main.go
-
-  assets:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-In the above example, `assets` will always run right before `build` if you run
-`task build`.
-
-A task can have only dependencies and no commands to group tasks together:
-
-```yaml
-version: '3'
-
-tasks:
-  assets:
-    deps: [js, css]
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-If there is more than one dependency, they always run in parallel for better
-performance.
-
-> You can also make the tasks given by the command line run in parallel by
-> using the `--parallel` flag (alias `-p`). Example: `task --parallel js css`.
-
-If you want to pass information to dependencies, you can do that the same
-manner as you would to [call another task](#calling-another-task):
-
-```yaml
-version: '3'
-
-tasks:
-  default:
-    deps:
-      - task: echo_sth
-        vars: {TEXT: "before 1"}
-      - task: echo_sth
-        vars: {TEXT: "before 2"}
-    cmds:
-      - echo "after"
-
-  echo_sth:
-    cmds:
-      - echo {{.TEXT}}
-```
-
-## Calling another task
-
-When a task has many dependencies, they are executed concurrently. This will
-often result in a faster build pipeline. But in some situations you may need
-to call other tasks serially. In this case, just use the following syntax:
-
-```yaml
-version: '3'
-
-tasks:
-  main-task:
-    cmds:
-      - task: task-to-be-called
-      - task: another-task
-      - echo "Both done"
-
-  task-to-be-called:
-    cmds:
-      - echo "Task to be called"
-
-  another-task:
-    cmds:
-      - echo "Another task"
-```
-
-Overriding variables in the called task is as simple as informing `vars`
-attribute:
-
-```yaml
-version: '3'
-
-tasks:
-  greet:
-    vars:
-      RECIPIENT: '{{default "World" .RECIPIENT}}'
-    cmds:
-      - echo "Hello, {{.RECIPIENT}}!"
-
-  greet-pessimistically:
-    cmds:
-      - task: greet
-        vars: {RECIPIENT: "Cruel World"}
-```
-
-The above syntax is also supported in `deps`.
-
-> NOTE: If you want to call a task declared in the root Taskfile from within an
-> [included Taskfile](#including-other-taskfiles), add a leading `:` like this:
-> `task: :task-name`.
-
-## Prevent unnecessary work
-
-### By fingerprinting locally generated files and their sources
-
-If a task generates something, you can inform Task the source and generated
-files, so Task will prevent to run them if not necessary.
-
-```yaml
-version: '3'
-
-tasks:
-  build:
-    deps: [js, css]
-    cmds:
-      - go build -v -i main.go
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-    sources:
-      - src/js/**/*.js
-    generates:
-      - public/script.js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-    sources:
-      - src/css/**/*.css
-    generates:
-      - public/style.css
-```
-
-`sources` and `generates` can be files or file patterns. When given,
-Task will compare the checksum of the source files to determine if it's
-necessary to run the task. If not, it will just print a message like
-`Task "js" is up to date`.
-You will probably want to ignore the `.task` folder in your `.gitignore` file
-(It's there that Task stores the last checksum).
-
-If you prefer this check to be made by the modification timestamp of the files,
-instead of its checksum (content), just set the `method` property to `timestamp`.
-
-```yaml
-version: '3'
-
-tasks:
-  build:
-    cmds:
-      - go build .
-    sources:
-      - ./*.go
-    generates:
-      - app{{exeExt}}
-    method: checksum
-```
-
-> TIP: method `none` skips any validation and always run the task.
-
-> NOTE: for the `checksum` (default) method to work, it's only necessary to
-> inform the source files, but if you want to use the `timestamp` method, you
-> also need to inform the generated files with `generates`.
-
-### Using programmatic checks to indicate a task is up to date.
-
-Alternatively, you can inform a sequence of tests as `status`. If no error
-is returned (exit status 0), the task is considered up-to-date:
-
-```yaml
-version: '3'
-
-tasks:
-  generate-files:
-    cmds:
-      - mkdir directory
-      - touch directory/file1.txt
-      - touch directory/file2.txt
-    # test existence of files
-    status:
-      - test -d directory
-      - test -f directory/file1.txt
-      - test -f directory/file2.txt
-```
-
-Normally, you would use `sources` in combination with
-`generates` - but for tasks that generate remote artifacts (Docker images,
-deploys, CD releases) the checksum source and timestamps require either
-access to the artifact or for an out-of-band refresh of the `.checksum`
-fingerprint file.
-
-Two special variables `{{.CHECKSUM}}` and `{{.TIMESTAMP}}` are available
-for interpolation within `status` commands, depending on the method assigned
-to fingerprint the sources. Only `source` globs are fingerprinted.
-
-Note that the `{{.TIMESTAMP}}` variable is a "live" Go `time.Time` struct, and
-can be formatted using any of the methods that `time.Time` responds to.
-
-See [the Go Time documentation](https://golang.org/pkg/time/) for more information.
-
-You can use `--force` or `-f` if you want to force a task to run even when
-up-to-date.
-
-Also, `task --status [tasks]...` will exit with a non-zero exit code if any of
-the tasks are not up-to-date.
-
-### Using programmatic checks to cancel execution of an task and it's dependencies
-
-In addition to `status` checks, there are also `preconditions` checks, which are
-the logical inverse of `status` checks.  That is, if you need a certain set of
-conditions to be _true_ you can use the `preconditions` stanza.
-`preconditions` are similar to `status` lines except they support `sh`
-expansion and they SHOULD all return 0.
-
-```yaml
-version: '3'
-
-tasks:
-  generate-files:
-    cmds:
-      - mkdir directory
-      - touch directory/file1.txt
-      - touch directory/file2.txt
-    # test existence of files
-    preconditions:
-      - test -f .env
-      - sh: "[ 1 = 0 ]"
-        msg: "One doesn't equal Zero, Halting"
-```
-
-Preconditions can set specific failure messages that can tell
-a user what steps to take using the `msg` field.
-
-If a task has a dependency on a sub-task with a precondition, and that
-precondition is not met - the calling task will fail.  Note that a task
-executed with a failing precondition will not run unless `--force` is
-given.
-
-Unlike `status` which will skip a task if it is up to date, and continue
-executing tasks that depend on it, a `precondition` will fail a task, along
-with any other tasks that depend on it.
-
-```yaml
-version: '3'
-
-tasks:
-  task-will-fail:
-    preconditions:
-      - sh: "exit 1"
-
-  task-will-also-fail:
-    deps:
-      - task-will-fail
-
-  task-will-still-fail:
-    cmds:
-      - task: task-will-fail
-      - echo "I will not run"
-```
-
-## Variables
-
-When doing interpolation of variables, Task will look for the below.
-They are listed below in order of importance (e.g. most important first):
-
-- Variables declared in the task definition
-- Variables given while calling a task from another
-  (See [Calling another task](#calling-another-task) above)
-- Global variables (those declared in the `vars:` option in the Taskfile)
-- Environment variables
-
-Example of sending parameters with environment variables:
-
-```bash
-$ TASK_VARIABLE=a-value task do-something
-```
-
-> TIP: A special variable `.TASK` is always available containing the task name.
-
-Since some shells don't support above syntax to set environment variables
-(Windows) tasks also accepts a similar style when not in the beginning of
-the command.
-
-```bash
-$ task write-file FILE=file.txt "CONTENT=Hello, World!" print "MESSAGE=All done!"
-```
-
-Example of locally declared vars:
-
-```yaml
-version: '3'
-
-tasks:
-  print-var:
-    cmds:
-      - echo "{{.VAR}}"
-    vars:
-      VAR: Hello!
-```
-
-Example of global vars in a `Taskfile.yml`:
-
-```yaml
-version: '3'
-
-vars:
-  GREETING: Hello from Taskfile!
-
-tasks:
-  greet:
-    cmds:
-      - echo "{{.GREETING}}"
-```
-
-### Dynamic variables
-
-The below syntax (`sh:` prop in a variable) is considered a dynamic variable.
-The value will be treated as a command and the output assigned. If there is one
-or more trailing newlines, the last newline will be trimmed.
-
-```yaml
-version: '3'
-
-tasks:
-  build:
-    cmds:
-      - go build -ldflags="-X main.Version={{.GIT_COMMIT}}" main.go
-    vars:
-      GIT_COMMIT:
-        sh: git log -n 1 --format=%h
-```
-
-This works for all types of variables.
-
-## Forwarding CLI arguments to commands
-
-If `--` is given in the CLI, all following paramaters are added to a
-special `.CLI_ARGS` variable. This is useful to forward arguments to another
-command.
-
-The below example will run `yarn install`.
-
-```bash
-$ task yarn -- install
-```
-
-```yaml
-version: '3'
-
-tasks:
-  yarn:
-    cmds:
-      - yarn {{.CLI_ARGS}}
-```
-
-## Go's template engine
-
-Task parse commands as [Go's template engine][gotemplate] before executing
-them. Variables are accessible through dot syntax (`.VARNAME`).
-
-All functions by the Go's [slim-sprig lib](https://go-task.github.io/slim-sprig/)
-are available. The following example gets the current date in a given format:
-
-```yaml
-version: '3'
-
-tasks:
-  print-date:
-    cmds:
-      - echo {{now | date "2006-01-02"}}
-```
-
-Task also adds the following functions:
-
-- `OS`: Returns operating system. Possible values are "windows", "linux",
-  "darwin" (macOS) and "freebsd".
-- `ARCH`: return the architecture Task was compiled to: "386", "amd64", "arm"
-  or "s390x".
-- `splitLines`: Splits Unix (\n) and Windows (\r\n) styled newlines.
-- `catLines`: Replaces Unix (\n) and Windows (\r\n) styled newlines with a space.
-- `toSlash`: Does nothing on Unix, but on Windows converts a string from `\`
-  path format to `/`.
-- `fromSlash`: Opposite of `toSlash`. Does nothing on Unix, but on Windows
-  converts a string from `\` path format to `/`.
-- `exeExt`: Returns the right executable extension for the current OS
-  (`".exe"` for Windows, `""` for others).
-
-Example:
-
-```yaml
-version: '3'
-
-tasks:
-  print-os:
-    cmds:
-      - echo '{{OS}} {{ARCH}}'
-      - echo '{{if eq OS "windows"}}windows-command{{else}}unix-command{{end}}'
-      # This will be path/to/file on Unix but path\to\file on Windows
-      - echo '{{fromSlash "path/to/file"}}'
-  enumerated-file:
-    vars:
-      CONTENT: |
-        foo
-        bar
-    cmds:
-      - |
-        cat << EOF > output.txt
-        {{range $i, $line := .CONTENT | splitLines -}}
-        {{printf "%3d" $i}}: {{$line}}
-        {{end}}EOF
-```
-
-## Help
-
-Running `task --list` (or `task -l`) lists all tasks with a description.
-The following Taskfile:
-
-```yaml
-version: '3'
-
-tasks:
-  build:
-    desc: Build the go binary.
-    cmds:
-      - go build -v -i main.go
-
-  test:
-    desc: Run all the go tests.
-    cmds:
-      - go test -race ./...
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-would print the following output:
-
-```bash
-* build:   Build the go binary.
-* test:    Run all the go tests.
-```
-
-## Display summary of task
-
-Running `task --summary task-name` will show a summary of a task.
-The following Taskfile:
-
-```yaml
-version: '3'
-
-tasks:
-  release:
-    deps: [build]
-    summary: |
-      Release your project to github
-
-      It will build your project before starting the release.
-      Please make sure that you have set GITHUB_TOKEN before starting.
-    cmds:
-      - your-release-tool
-
-  build:
-    cmds:
-      - your-build-tool
-```
-
-with running ``task --summary release`` would print the following output:
-
-```
-task: release
-
-Release your project to github
-
-It will build your project before starting the release.
-Please make sure that you have set GITHUB_TOKEN before starting.
-
-dependencies:
- - build
-
-commands:
- - your-release-tool
-```
-If a summary is missing, the description will be printed.
-If the task does not have a summary or a description, a warning is printed.
-
-Please note: *showing the summary will not execute the command*.
-
-## Overriding task name
-
-Sometimes you may want to override the task name print on summary, up-to-date
-messages to STDOUT, etc. In this case you can just set `label:`, which can also
-be interpolated with variables:
-
-```yaml
-version: '3'
-
-tasks:
-  default:
-    - task: print
-      vars:
-        MESSAGE: hello
-    - task: print
-      vars:
-        MESSAGE: world
-
-  print:
-    label: 'print-{{.MESSAGE}}'
-    cmds:
-      - echo "{{.MESSAGE}}"
-```
-
-## Silent mode
-
-Silent mode disables echoing of commands before Task runs it.
-For the following Taskfile:
-
-```yaml
-version: '3'
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-```
-
-Normally this will be print:
-
-```sh
-echo "Print something"
-Print something
-```
-
-With silent mode on, the below will be print instead:
-
-```sh
-Print something
-```
-
-There are four ways to enable silent mode:
-
-* At command level:
-
-```yaml
-version: '3'
-
-tasks:
-  echo:
-    cmds:
-      - cmd: echo "Print something"
-        silent: true
-```
-
-* At task level:
-
-```yaml
-version: '3'
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-    silent: true
-```
-
-* Globally at Taskfile level:
-
-```yaml
-version: '3'
-
-silent: true
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-```
-
-* Or globally with `--silent` or `-s` flag
-
-If you want to suppress STDOUT instead, just redirect a command to `/dev/null`:
-
-```yaml
-version: '3'
-
-tasks:
-  echo:
-    cmds:
-      - echo "This will print nothing" > /dev/null
-```
-
-## Dry run mode
-
-Dry run mode (`--dry`) compiles and steps through each task, printing the commands
-that would be run without executing them. This is useful for debugging your Taskfiles.
-
-## Ignore errors
-
-You have the option to ignore errors during command execution.
-Given the following Taskfile:
-
-```yaml
-version: '3'
-
-tasks:
-  echo:
-    cmds:
-      - exit 1
-      - echo "Hello World"
-```
-
-Task will abort the execution after running `exit 1` because the status code `1` stands for `EXIT_FAILURE`.
-However it is possible to continue with execution using `ignore_error`:
-
-```yaml
-version: '3'
-
-tasks:
-  echo:
-    cmds:
-      - cmd: exit 1
-        ignore_error: true
-      - echo "Hello World"
-```
-
-`ignore_error` can also be set for a task, which mean errors will be suppressed
-for all commands. But keep in mind this option won't propagate to other tasks
-called either by `deps` or `cmds`!
-
-## Output syntax
-
-By default, Task just redirect the STDOUT and STDERR of the running commands
-to the shell in real time. This is good for having live feedback for log
-printed by commands, but the output can become messy if you have multiple
-commands running at the same time and printing lots of stuff.
-
-To make this more customizable, there are currently three different output
-options you can choose:
-
-- `interleaved` (default)
-- `group`
-- `prefixed`
-
-To choose another one, just set it to root in the Taskfile:
-
-```yaml
-version: '3'
-
-output: 'group'
-
-tasks:
-  # ...
-```
-
- The `group` output will print the entire output of a command once, after it
- finishes, so you won't have live feedback for commands that take a long time
- to run.
-
- The `prefix` output will prefix every line printed by a command with
- `[task-name] ` as the prefix, but you can customize the prefix for a command
- with the `prefix:` attribute:
-
- ```yaml
-version: '3'
-
-output: prefixed
-
-tasks:
-  default:
-    deps:
-      - task: print
-        vars: {TEXT: foo}
-      - task: print
-        vars: {TEXT: bar}
-      - task: print
-        vars: {TEXT: baz}
-
-  print:
-    cmds:
-      - echo "{{.TEXT}}"
-    prefix: "print-{{.TEXT}}"
-    silent: true
-```
-
-```bash
-$ task default
-[print-foo] foo
-[print-bar] bar
-[print-baz] baz
-```
-
-> The `output` option can also be specified by the `--output` or `-o` flags.
-
-## Short task syntax
-
-Starting on Task v3, you can now write tasks with a shorter syntax if they
-have the default settings (e.g. no custom `env:`, `vars:`, `desc:`, `silent:` , etc):
-
-```yaml
-version: '3'
-
-tasks:
-  build: go build -v -o ./app{{exeExt}} .
-
-  run:
-    - task: build
-    - ./app{{exeExt}} -h localhost -p 8080
-```
-
-## Watch tasks
-
-With the flags `--watch` or `-w` task will watch for file changes
-and run the task again. This requires the `sources` attribute to be given,
-so task knows which files to watch.
