 # Changelog
 
+# v3.0.0 - Preview 3
+
+- 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)).
+- Added option to make included Taskfile run commands on its own directory
+  ([#260](https://github.com/go-task/task/issues/260), [#144](https://github.com/go-task/task/issues/144))
+
+# v3.0.0 - Preview 2
+
+- 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)).
+
+## v3.0.0 - Preview 1
+
+- 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)).
+
+## v2.8.0 - 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)).
+- Fixed bug where calling the `task` CLI only informing global vars would not
+  execute the `default` task.
+- Add hability to silent all tasks by adding `silent: true` a the root of the
+  Taskfile.
+
+## v2.7.1 - 2019-11-10
+
+- Fix error being raised when `exit 0` was called
+  ([#251](https://github.com/go-task/task/issues/251)).
+
+## v2.7.0 - 2019-09-22
+
+- 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)).
+- A task with `method: checksum` will now re-run if generated files are deleted
+  ([#228](https://github.com/go-task/task/pull/228), [#238](https://github.com/go-task/task/issues/238)).
+
+## v2.6.0 - 2019-07-21
+
+- Fixed some bugs regarding minor version checks on `version:`.
+- Add `preconditions:` to task
+  ([#205](https://github.com/go-task/task/pull/205)).
+- Create directory informed on `dir:` if it doesn't exist
+  ([#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
+  ([go-task/homebrew-tap#1](https://github.com/go-task/homebrew-tap/pull/1)).
+
 ## v2.5.2 - 2019-05-11
 
 - Reverted YAML upgrade due issues with CRLF on Windows

+# 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'

+
+  bar:
+    cmds:
+      - echo 'bar'
+
+  baz:
+    cmds:
+      - echo 'baz'
+```
+
+## Use upper-case variable names
+

+

+  binary_name: myapp
+
+tasks:
+  build:
+    cmds:

+  BINARY_NAME: myapp

+
+## Don't wrap vars in spaces when templating

+
+tasks:
+  greet:
+    cmds:
+      - echo '{{ .MESSAGE }}'
+
+
+# good
+version: 2
+
+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: 2
+
+tasks:
+  do_something_fancy:
+    cmds:
+      - echo 'Do something'
+
+
+# good
+version: 2
+
+tasks:
+  do-something-fancy:
+    cmds:
+      - echo 'Do something'
+```
+
+## Use colon for task namespacing

+    cmds:
+      - docker ...

+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: '2'
+
+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: '2'
+tasks:
+  task_will_fail:

-# go-homedir
-
-This is a Go library for detecting the user's home directory without
-the use of cgo, so the library can be used in cross-compilation environments.
-
-Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
-for a user, and `homedir.Expand()` to expand the `~` in a path to the home
-directory.
-
-**Why not just use `os/user`?** The built-in `os/user` package requires
-cgo on Darwin systems. This means that any Go code that uses that package
-cannot cross compile. But 99% of the time the use for `os/user` is just to
-retrieve the home directory, which we can do for the current user without
-cgo. This library does that, enabling cross-compilation.

-// Incoming requests to a server should create a Context, and outgoing calls to

-//
-// Programs that use Contexts should follow these rules to keep interfaces
-// consistent across packages and enable static analysis tools to check context
-// propagation:
-//
-// Do not store Contexts inside a struct type; instead, pass a Context
-// explicitly to each function that needs it. The Context should be the first
-// parameter, typically named ctx:
-//
-// 	func DoSomething(ctx context.Context, arg Arg) error {
-// 		// ... use ctx ...
-// 	}
-//
-// Do not pass a nil Context, even if a function permits it. Pass context.TODO
-// if you are unsure about which Context to use.
-//
-// Use context Values only for request-scoped data that transits processes and
-// APIs, not for passing optional parameters to functions.
-//
-// The same Context may be passed to functions running in different goroutines;
