 # Changelog
 
+## v3.17.0
+
+- Add a "Did you mean ...?" suggestion when a task does not exits another one
+  with a similar name is found
+  ([#867](https://github.com/go-task/task/issues/867), [#880](https://github.com/go-task/task/pull/880)).
+- Now YAML parse errors will print which Taskfile failed to parse
+  ([#885](https://github.com/go-task/task/issues/885), [#887](https://github.com/go-task/task/pull/887)).
+- Add ability to set `aliases` for tasks and namespaces ([#268](https://github.com/go-task/task/pull/268), [#340](https://github.com/go-task/task/pull/340), [#879](https://github.com/go-task/task/pull/879)).
+- Improvements to Fish shell completion
+  ([#897](https://github.com/go-task/task/pull/897)).
+- Added ability to set a different watch interval by setting
+  `interval: '500ms'` or using the `--interval=500ms` flag
+  ([#813](https://github.com/go-task/task/issues/813), [#865](https://github.com/go-task/task/pull/865)).
+- Add colored output to `--list`, `--list-all` and `--summary` flags ([#845](https://github.com/go-task/task/pull/845), [#874](https://github.com/go-task/task/pull/874)).
+- Fix unexpected behavior where `label:` was being shown instead of the task
+  name on `--list`
+  ([#603](https://github.com/go-task/task/issues/603), [#877](https://github.com/go-task/task/pull/877)).
+
+## v3.16.0 - 2022-09-29
+
+- Add `npm` as new installation method: `npm i -g @go-task/cli`
+  ([#870](https://github.com/go-task/task/issues/870), [#871](https://github.com/go-task/task/pull/871), [npm package](https://www.npmjs.com/package/@go-task/cli)).
+- Add support to marking tasks and includes as internal, which will hide them
+  from `--list` and `--list-all`
+  ([#818](https://github.com/go-task/task/pull/818)).
+
+## v3.15.2 - 2022-09-08
+
+- Fix error when using variable in `env:` introduced in the previous release
+  ([#858](https://github.com/go-task/task/issues/858), [#866](https://github.com/go-task/task/pull/866)).
+- Fix handling of `CLI_ARGS` (`--`) in Bash completion
+  ([#863](https://github.com/go-task/task/pull/863)).
+- On zsh completion, add ability to replace `--list-all` with `--list` as
+  already possible on the Bash completion
+  ([#861](https://github.com/go-task/task/pull/861)).
+
+## v3.15.0 - 2022-09-03
+
+- Add new special variables `ROOT_DIR` and `TASKFILE_DIR`. This was a highly
+  requested feature
+  ([#215](https://github.com/go-task/task/issues/215), [#857](https://github.com/go-task/task/pull/857), [Documentation](https://taskfile.dev/api/#special-variables)).
+- Follow symlinks on `sources`
+  ([#826](https://github.com/go-task/task/issues/826), [#831](https://github.com/go-task/task/pull/831)).
+- Improvements and fixes to Bash completion
+  ([#835](https://github.com/go-task/task/pull/835), [#844](https://github.com/go-task/task/pull/844)).
+
+## v3.14.1 - 2022-08-03
+
+- Always resolve relative include paths relative to the including Taskfile
+  ([#822](https://github.com/go-task/task/issues/822), [#823](https://github.com/go-task/task/pull/823)).
+- Fix ZSH and PowerShell completions to consider all tasks instead of just the
+  public ones (those with descriptions)
+  ([#803](https://github.com/go-task/task/pull/803)).
+
+## v3.14.0 - 2022-07-08
+
+- Add ability to override the `.task` directory location with the
+  `TASK_TEMP_DIR` environment variable.
+- Allow to override Task colors using environment variables:
+  `TASK_COLOR_RESET`, `TASK_COLOR_BLUE`, `TASK_COLOR_GREEN`,
+  `TASK_COLOR_CYAN`, `TASK_COLOR_YELLOW`, `TASK_COLOR_MAGENTA`
+  and `TASK_COLOR_RED`
+  ([#568](https://github.com/go-task/task/pull/568), [#792](https://github.com/go-task/task/pull/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](https://github.com/go-task/task/issues/779)).
+- Starting on this release, ARM architecture binaries are been released to Snap
+  as well
+  ([#795](https://github.com/go-task/task/issues/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](https://github.com/go-task/task/issues/785), [mvdan/sh#884](https://github.com/mvdan/sh/issues/884), [mvdan/sh#893](https://github.com/mvdan/sh/pull/893)).
+
+## v3.13.0 - 2022-06-13
+
+- Added `-n` as an alias to `--dry`
+  ([#776](https://github.com/go-task/task/issues/776), [#777](https://github.com/go-task/task/pull/777)).
+- Fix behavior of interrupt (SIGINT, SIGTERM) signals. Task will now give time
+  for the processes running to do cleanup work
+  ([#458](https://github.com/go-task/task/issues/458), [#479](https://github.com/go-task/task/pull/479), [#728](https://github.com/go-task/task/issues/728), [#769](https://github.com/go-task/task/pull/769)).
+- Add new `--exit-code` (`-x`) flag that will pass-through the exit form the
+  command being ran
+  ([#755](https://github.com/go-task/task/pull/755)).
+
+## v3.12.1 - 2022-05-10
+
+- Fixed bug where, on Windows, variables were ending with `\r` because we were
+  only removing the final `\n` but not `\r\n`
+  ([#717](https://github.com/go-task/task/issues/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](https://github.com/go-task/task/pull/691)).
+- Added support for multi-level inclusion of Taskfiles. This means that
+  included Taskfiles can also include other Taskfiles. Before this was limited
+  to one level
+  ([#390](https://github.com/go-task/task/issues/390), [#623](https://github.com/go-task/task/discussions/623), [#656](https://github.com/go-task/task/pull/656)).
+- Add ability to specify vars when including a Taskfile.
+  [Check out the documentation](https://taskfile.dev/#/usage?id=vars-of-included-taskfiles)
+  for more information.
+  ([#677](https://github.com/go-task/task/pull/677)).
+
+## v3.11.0 - 2022-02-19
+
+- Task now supports printing begin and end messages when using the `group`
+  output mode, useful for grouping tasks in CI systems.
+  [Check out the documentation](http://taskfile.dev/#/usage?id=output-syntax) for more information
+  ([#647](https://github.com/go-task/task/issues/647), [#651](https://github.com/go-task/task/pull/651)).
+- Add `Taskfile.dist.yml` and `Taskfile.dist.yaml` to the supported file
+  name list. [Check out the documentation](https://taskfile.dev/#/usage?id=supported-file-names) for more information
+  ([#498](https://github.com/go-task/task/issues/498), [#666](https://github.com/go-task/task/pull/666)).
+
+## v3.10.0 - 2022-01-04
+
+- A new `--list-all` (alias `-a`) flag is now available. It's similar to the
+  exiting `--list` (`-l`) but prints all tasks, even those without a
+  description
+  ([#383](https://github.com/go-task/task/issues/383), [#401](https://github.com/go-task/task/pull/401)).
+- It's now possible to schedule cleanup commands to run once a task finishes
+  with the `defer:` keyword
+  ([Documentation](https://taskfile.dev/#/usage?id=doing-task-cleanup-with-defer), [#475](https://github.com/go-task/task/issues/475), [#626](https://github.com/go-task/task/pull/626)).
+- Remove long deprecated and undocumented `$` variable prefix and `^` command
+  prefix
+  ([#642](https://github.com/go-task/task/issues/642), [#644](https://github.com/go-task/task/issues/644), [#645](https://github.com/go-task/task/pull/645)).
+- Add support for `.yaml` extension (as an alternative to `.yml`).
+  This was requested multiple times throughout the years. Enjoy!
+  ([#183](https://github.com/go-task/task/issues/183), [#184](https://github.com/go-task/task/pull/184), [#369](https://github.com/go-task/task/issues/369), [#584](https://github.com/go-task/task/issues/584), [#621](https://github.com/go-task/task/pull/621)).
+- Fixed error when computing a variable when the task directory do not exist
+  yet
+  ([#481](https://github.com/go-task/task/issues/481), [#579](https://github.com/go-task/task/pull/579)).
+
+## v3.9.2 - 2021-12-02
+
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains a fix a for
+  a important regression on Windows
+  ([#619](https://github.com/go-task/task/issues/619), [mvdan/sh#768](https://github.com/mvdan/sh/issues/768), [mvdan/sh#769](https://github.com/mvdan/sh/pull/769)).
+
+## v3.9.1 - 2021-11-28
+
+- Add logging in verbose mode for when a task starts and finishes
+  ([#533](https://github.com/go-task/task/issues/533), [#588](https://github.com/go-task/task/pull/588)).
+- Fix an issue with preconditions and context errors
+  ([#597](https://github.com/go-task/task/issues/597), [#598](https://github.com/go-task/task/pull/598)).
+- Quote each `{{.CLI_ARGS}}` argument to prevent one with spaces to become many
+  ([#613](https://github.com/go-task/task/pull/613)).
+- Fix  nil pointer when `cmd:` was left empty
+  ([#612](https://github.com/go-task/task/issues/612), [#614](https://github.com/go-task/task/pull/614)).
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains two
+  relevant fixes:
+  - Fix quote of empty strings in `shellQuote`
+    ([#609](https://github.com/go-task/task/issues/609), [mvdan/sh#763](https://github.com/mvdan/sh/issues/763)).
+  - Fix issue of wrong environment variable being picked when there's another
+    very similar one
+    ([#586](https://github.com/go-task/task/issues/586), [mvdan/sh#745](https://github.com/mvdan/sh/pull/745)).
+- Install shell completions automatically when installing via Homebrew
+  ([#264](https://github.com/go-task/task/issues/264), [#592](https://github.com/go-task/task/pull/592), [go-task/homebrew-tap#2](https://github.com/go-task/homebrew-tap/pull/2)).
+
+## v3.9.0 - 2021-10-02
+
+- A new `shellQuote` function was added to the template system
+  (`{{shellQuote "a string"}}`) to ensure a string is safe for use in shell
+  ([mvdan/sh#727](https://github.com/mvdan/sh/pull/727), [mvdan/sh#737](https://github.com/mvdan/sh/pull/737), [Documentation](https://pkg.go.dev/mvdan.cc/sh/v3@v3.4.0/syntax#Quote))
+- In this version [mvdan.cc/sh](https://github.com/mvdan/sh) was upgraded
+  with some small fixes and features
+  - The `read -p` flag is now supported
+    ([#314](https://github.com/go-task/task/issues/314), [mvdan/sh#551](https://github.com/mvdan/sh/issues/551), [mvdan/sh#772](https://github.com/mvdan/sh/pull/722))
+  - The `pwd -P` and `pwd -L` flags are now supported
+    ([#553](https://github.com/go-task/task/issues/553), [mvdan/sh#724](https://github.com/mvdan/sh/issues/724), [mvdan/sh#728](https://github.com/mvdan/sh/pull/728))
+  - The `$GID` environment variable is now correctly being set
+    ([#561](https://github.com/go-task/task/issues/561), [mvdan/sh#723](https://github.com/mvdan/sh/pull/723))
+
+## v3.8.0 - 2021-09-26
+
+- Add `interactive: true` setting to improve support for interactive CLI apps
+  ([#217](https://github.com/go-task/task/issues/217), [#563](https://github.com/go-task/task/pull/563)).
+- Fix some `nil` errors
+  ([#534](https://github.com/go-task/task/issues/534), [#573](https://github.com/go-task/task/pull/573)).
+- Add ability to declare an included Taskfile as optional
+  ([#519](https://github.com/go-task/task/issues/519), [#552](https://github.com/go-task/task/pull/552)).
+- Add support for including Taskfiles in the home directory by using `~`
+  ([#539](https://github.com/go-task/task/issues/539), [#557](https://github.com/go-task/task/pull/557)).
+
+## v3.7.3 - 2021-09-04
+
+- Add official support to Apple M1 ([#564](https://github.com/go-task/task/pull/564), [#567](https://github.com/go-task/task/pull/567)).
+- Our [official Homebrew tap](https://github.com/go-task/homebrew-tap) will
+  support more platforms, including Apple M1
+
+## v3.7.0 - 2021-07-31
+
+- Add `run:` setting to control if tasks should run multiple times or not.
+  Available options are `always` (the default), `when_changed` (if a variable
+  modified the task) and `once` (run only once no matter what).
+  This is a long time requested feature. Enjoy!
+  ([#53](https://github.com/go-task/task/issues/53), [#359](https://github.com/go-task/task/pull/359)).
+
+## v3.6.0 - 2021-07-10
+
+- Allow using both `sources:` and `status:` in the same task
+  ([#411](https://github.com/go-task/task/issues/411), [#427](https://github.com/go-task/task/issues/427), [#477](https://github.com/go-task/task/pull/477)).
+- Small optimization and bug fix: don't compute variables if not needed for
+  `dotenv:` ([#517](https://github.com/go-task/task/issues/517)).
+
+## v3.5.0 - 2021-07-04
+
+- Add support for interpolation in `dotenv:`
+  ([#433](https://github.com/go-task/task/discussions/433), [#434](https://github.com/go-task/task/issues/434), [#453](https://github.com/go-task/task/pull/453)).
+
+## v3.4.3 - 2021-05-30
+
+- Add support for the `NO_COLOR` environment variable.
+  ([#459](https://github.com/go-task/task/issues/459), [fatih/color#137](https://github.com/fatih/color/pull/137)).
+- Fix bug where sources were not considering the right directory
+  in `--watch` mode
+  ([#484](https://github.com/go-task/task/issues/484), [#485](https://github.com/go-task/task/pull/485)).
+
+## v3.4.2 - 2021-04-23
+
+- On watch, report which file failed to read
+  ([#472](https://github.com/go-task/task/pull/472)).
+- Do not try to catch SIGKILL signal, which are not actually possible
+  ([#476](https://github.com/go-task/task/pull/476)).
+- Improve version reporting when building Task from source using Go Modules
+  ([#462](https://github.com/go-task/task/pull/462), [#473](https://github.com/go-task/task/pull/473)).
+
+## v3.4.1 - 2021-04-17
+
+- Improve error reporting when parsing YAML: in some situations where you
+  would just see an generic error, you'll now see the actual error with
+  more detail: the YAML line the failed to parse, for example
+  ([#467](https://github.com/go-task/task/issues/467)).
+- A JSON Schema was published [here](https://json.schemastore.org/taskfile.json)
+  and is automatically being used by some editors like Visual Studio Code
+  ([#135](https://github.com/go-task/task/issues/135)).
+- Print task name before the command in the log output
+  ([#398](https://github.com/go-task/task/pull/398)).
+
+## 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)).
+- 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))
+- 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)).
+- 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
+  ([#201](https://github.com/go-task/task/issues/201), [go-yaml/yaml#450](https://github.com/go-yaml/yaml/issues/450)).
+- Allow setting global variables through the CLI
+  ([#192](https://github.com/go-task/task/issues/192)).
+
+## 2.5.1 - 2019-04-27
+
+- Fixed some issues with interactive command line tools, where sometimes
+  the output were not being shown, and similar issues
+  ([#114](https://github.com/go-task/task/issues/114), [#190](https://github.com/go-task/task/issues/190), [#200](https://github.com/go-task/task/pull/200)).
+- Upgraded [go-yaml/yaml](https://github.com/go-yaml/yaml) from v2 to v3.
+
+## v2.5.0 - 2019-03-16
+
+- We moved from the taskfile.org domain to the new fancy taskfile.dev domain.
+  While stuff is being redirected, we strongly recommend to everyone that use
+  [this install script](https://taskfile.dev/#/installation?id=install-script)
+  to use the new taskfile.dev domain on scripts from now on.
+- Fixed to the ZSH completion
+  ([#182](https://github.com/go-task/task/pull/182)).
+- Add [`--summary` flag along with `summary:` task attribute](https://taskfile.org/#/usage?id=display-summary-of-task)
+  ([#180](https://github.com/go-task/task/pull/180)).
+
 ## v2.4.0 - 2019-02-21
 
 - Allow calling a task of the root Taskfile from an included Taskfile

+
+### Taskfile
+
+| Attribute | Type | Default | Description |

+| `includes` | [`map[string]Include`](#include) | | Additional Taskfiles to be included. |
+| `output` | `string` | `interleaved` | Output mode. Available options: `interleaved`, `group` and `prefixed`. |

+| `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). |
+| `vars` | [`map[string]Variable`](#variable) | | Global variables. |
+| `env` | [`map[string]Variable`](#variable) | | Global environment. |
+| `dotenv` | `[]string` | | A list of `.env` file paths to be parsed. |
+| `tasks` | [`map[string]Task`](#task) | | The task definitions. |
+
+### Include
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `taskfile` | `string` | | The path for the Taskfile or directory to be included. If a directory, Task will look for files named `Taskfile.yml` or `Taskfile.yaml` inside that directory. If a relative path, resolved relative to the directory containing the including Taskfile. |

+| `optional` | `bool` | `false` | If `true`, no errors will be thrown if the specified file does not exist. |
+| `internal` | `bool` | `false` | If `true`, tasks will not be callable from the command line and will be omitted from both `--list` and `--list-all`. |
+| `aliases` | `[]string` | | Alternative names for the namespace of the included Taskfile. |
+
+:::info
+
+Informing only a string like below is equivalent to setting that value to the `taskfile` attribute.
+
+```yaml
+includes:
+  foo: ./path
+```
+
+:::
+
+### Task
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `desc` | `string` | | A short description of the task. This is listed when calling `task --list`. |
+| `summary` | `string` | | A longer description of the task. This is listed when calling `task --summary [task]`. |
+| `aliases` | `[]string` | | Alternative names for the task. |
+| `label` | `string` | | Overrides the name of the task in the output when a task is run. Supports variables. |
+| `sources` | `[]string` | | List of sources to check before running this task. Relevant for `checksum` and `timestamp` methods. Can be file paths or star globs. |
+| `dir` | `string` | | The current directory which this task should run. |
+| `method` | `string` | `checksum` | Method used by this task. Default to the one declared globally or `checksum`. Available options: `checksum`, `timestamp` and `none` |
+| `silent` | `bool` | `false` | Skips some output for this task. Note that STDOUT and STDERR of the commands will still be redirected. |
+| `internal` | `bool` | `false` | If `true`, this task will not be callable from the command line and will be omitted from both `--list` and `--list-all`. |
+| `run` | `string` | The one declared globally in the Taskfile or `always` | Specifies whether the task should run again or not if called more than once. Available options: `always`, `once` and `when_changed`. |
+| `prefix` | `string` | | Allows to override the prefix print before the STDOUT. Only relevant when using the `prefixed` output mode. |
+| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing the commands. |
+| `generates` | `[]string` | | List of files meant to be generated by this task. Relevant for `timestamp` method. Can be file paths or star globs. |
+| `status` | `[]string` | | List of commands to check if this task should run. The task is skipped otherwise. This overrides `method`, `sources` and `generates`. |
+| `preconditions` | [`[]Precondition`](#precondition) | | List of commands to check if this task should run. The task errors otherwise. |
+| `vars` | [`map[string]Variable`](#variable) | | Task variables. |
+| `env` | [`map[string]Variable`](#variable) | | Task environment. |
+| `deps` | [`[]Dependency`](#dependency) | | List of dependencies of this task. |
+| `cmds` | [`[]Command`](#command) | | List of commands to be executed. |
+
+:::info
+
+These alternative syntaxes are available. They will set the given values to
+`cmds` and everything else will be set to their default values:
+
+```yaml
+tasks:
+  foo: echo "foo"
+
+  foobar:
+    - echo "foo"
+    - echo "bar"
+
+  baz:
+    cmd: echo "baz"
+```
+
+:::
+
+### 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. |
+
+:::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]
+```
+
+:::
+
+### Command
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| `cmd` | `string` | | The shell command to be executed. |
+| `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`. |
+| `silent` | `bool` | `false` | Skips some output for this command. Note that STDOUT and STDERR of the commands will still be redirected. |
+| `ignore_error` | `bool` | `false` | Continue execution if errors happen while executing the command. |
+| `task` | `string` | | Set this to trigger execution of another task instead of running a command. This cannot be set together with `cmd`. |
+| `vars` | [`map[string]Variable`](#variable) | | Optional additional variables to be passed to the referenced task. Only relevant when setting `task` instead of `cmd`. |
+
+:::info
+
+If given as a a string, the value will be assigned to `cmd`:
+
+```yaml
+tasks:
+  foo:
+    cmds:
+      - echo "foo"
+      - echo "bar"
+```
+
+:::
+
+### Variable
+
+| Attribute | Type | Default | Description |
+| - | - | - | - |
+| *itself* | `string` | | A static value that will be set to the variable. |
+| `sh` | `string` | | A shell command. The output (`STDOUT`) will be assigned to the variable. |
+
+:::info
+
+Static and dynamic variables have different syntaxes, like below:
+
+```yaml
+vars:
+  STATIC: static
+  DYNAMIC:
+    sh: echo "dynamic"
+```
+
+:::
+
+### 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

+# Changelog
+
+## v3.17.0
+
+- Add a "Did you mean ...?" suggestion when a task does not exits another one
+  with a similar name is found
+  ([#867](https://github.com/go-task/task/issues/867), [#880](https://github.com/go-task/task/pull/880)).
+- Now YAML parse errors will print which Taskfile failed to parse
+  ([#885](https://github.com/go-task/task/issues/885), [#887](https://github.com/go-task/task/pull/887)).
+- Add ability to set `aliases` for tasks and namespaces ([#268](https://github.com/go-task/task/pull/268), [#340](https://github.com/go-task/task/pull/340), [#879](https://github.com/go-task/task/pull/879)).
+- Improvements to Fish shell completion
+  ([#897](https://github.com/go-task/task/pull/897)).
+- Added ability to set a different watch interval by setting
+  `interval: '500ms'` or using the `--interval=500ms` flag
+  ([#813](https://github.com/go-task/task/issues/813), [#865](https://github.com/go-task/task/pull/865)).
+- Add colored output to `--list`, `--list-all` and `--summary` flags ([#845](https://github.com/go-task/task/pull/845), [#874](https://github.com/go-task/task/pull/874)).
+- Fix unexpected behavior where `label:` was being shown instead of the task
+  name on `--list`
+  ([#603](https://github.com/go-task/task/issues/603), [#877](https://github.com/go-task/task/pull/877)).
+
+## v3.16.0 - 2022-09-29
+
+- Add `npm` as new installation method: `npm i -g @go-task/cli`
+  ([#870](https://github.com/go-task/task/issues/870), [#871](https://github.com/go-task/task/pull/871), [npm package](https://www.npmjs.com/package/@go-task/cli)).
+- Add support to marking tasks and includes as internal, which will hide them
+  from `--list` and `--list-all`
+  ([#818](https://github.com/go-task/task/pull/818)).
+
+## v3.15.2 - 2022-09-08
+
+- Fix error when using variable in `env:` introduced in the previous release
+  ([#858](https://github.com/go-task/task/issues/858), [#866](https://github.com/go-task/task/pull/866)).
+- Fix handling of `CLI_ARGS` (`--`) in Bash completion
+  ([#863](https://github.com/go-task/task/pull/863)).
+- On zsh completion, add ability to replace `--list-all` with `--list` as
+  already possible on the Bash completion
+  ([#861](https://github.com/go-task/task/pull/861)).
+
+## v3.15.0 - 2022-09-03
+
+- Add new special variables `ROOT_DIR` and `TASKFILE_DIR`. This was a highly
+  requested feature
+  ([#215](https://github.com/go-task/task/issues/215), [#857](https://github.com/go-task/task/pull/857), [Documentation](https://taskfile.dev/api/#special-variables)).
+- Follow symlinks on `sources`
+  ([#826](https://github.com/go-task/task/issues/826), [#831](https://github.com/go-task/task/pull/831)).
+- Improvements and fixes to Bash completion
+  ([#835](https://github.com/go-task/task/pull/835), [#844](https://github.com/go-task/task/pull/844)).
+
+## v3.14.1 - 2022-08-03
+
+- Always resolve relative include paths relative to the including Taskfile
+  ([#822](https://github.com/go-task/task/issues/822), [#823](https://github.com/go-task/task/pull/823)).
+- Fix ZSH and PowerShell completions to consider all tasks instead of just the
+  public ones (those with descriptions)
+  ([#803](https://github.com/go-task/task/pull/803)).
+
+## v3.14.0 - 2022-07-08
+
+- Add ability to override the `.task` directory location with the
+  `TASK_TEMP_DIR` environment variable.
+- Allow to override Task colors using environment variables:
+  `TASK_COLOR_RESET`, `TASK_COLOR_BLUE`, `TASK_COLOR_GREEN`,
+  `TASK_COLOR_CYAN`, `TASK_COLOR_YELLOW`, `TASK_COLOR_MAGENTA`
+  and `TASK_COLOR_RED`
+  ([#568](https://github.com/go-task/task/pull/568), [#792](https://github.com/go-task/task/pull/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](https://github.com/go-task/task/issues/779)).
+- Starting on this release, ARM architecture binaries are been released to Snap
+  as well
+  ([#795](https://github.com/go-task/task/issues/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](https://github.com/go-task/task/issues/785), [mvdan/sh#884](https://github.com/mvdan/sh/issues/884), [mvdan/sh#893](https://github.com/mvdan/sh/pull/893)).
+
+## v3.13.0 - 2022-06-13
+
+- Added `-n` as an alias to `--dry`
+  ([#776](https://github.com/go-task/task/issues/776), [#777](https://github.com/go-task/task/pull/777)).
+- Fix behavior of interrupt (SIGINT, SIGTERM) signals. Task will now give time
+  for the processes running to do cleanup work
+  ([#458](https://github.com/go-task/task/issues/458), [#479](https://github.com/go-task/task/pull/479), [#728](https://github.com/go-task/task/issues/728), [#769](https://github.com/go-task/task/pull/769)).
+- Add new `--exit-code` (`-x`) flag that will pass-through the exit form the
+  command being ran
+  ([#755](https://github.com/go-task/task/pull/755)).
+
+## v3.12.1 - 2022-05-10
+
+- Fixed bug where, on Windows, variables were ending with `\r` because we were
+  only removing the final `\n` but not `\r\n`
+  ([#717](https://github.com/go-task/task/issues/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](https://github.com/go-task/task/pull/691)).
+- Added support for multi-level inclusion of Taskfiles. This means that
+  included Taskfiles can also include other Taskfiles. Before this was limited
+  to one level
+  ([#390](https://github.com/go-task/task/issues/390), [#623](https://github.com/go-task/task/discussions/623), [#656](https://github.com/go-task/task/pull/656)).
+- Add ability to specify vars when including a Taskfile.
+  [Check out the documentation](https://taskfile.dev/#/usage?id=vars-of-included-taskfiles)
+  for more information.
+  ([#677](https://github.com/go-task/task/pull/677)).
+
+## v3.11.0 - 2022-02-19
+
+- Task now supports printing begin and end messages when using the `group`
+  output mode, useful for grouping tasks in CI systems.
+  [Check out the documentation](http://taskfile.dev/#/usage?id=output-syntax) for more information
+  ([#647](https://github.com/go-task/task/issues/647), [#651](https://github.com/go-task/task/pull/651)).
+- Add `Taskfile.dist.yml` and `Taskfile.dist.yaml` to the supported file
+  name list. [Check out the documentation](https://taskfile.dev/#/usage?id=supported-file-names) for more information
+  ([#498](https://github.com/go-task/task/issues/498), [#666](https://github.com/go-task/task/pull/666)).
+
+## v3.10.0 - 2022-01-04
+
+- A new `--list-all` (alias `-a`) flag is now available. It's similar to the
+  exiting `--list` (`-l`) but prints all tasks, even those without a
+  description
+  ([#383](https://github.com/go-task/task/issues/383), [#401](https://github.com/go-task/task/pull/401)).
+- It's now possible to schedule cleanup commands to run once a task finishes
+  with the `defer:` keyword
+  ([Documentation](https://taskfile.dev/#/usage?id=doing-task-cleanup-with-defer), [#475](https://github.com/go-task/task/issues/475), [#626](https://github.com/go-task/task/pull/626)).
+- Remove long deprecated and undocumented `$` variable prefix and `^` command
+  prefix
+  ([#642](https://github.com/go-task/task/issues/642), [#644](https://github.com/go-task/task/issues/644), [#645](https://github.com/go-task/task/pull/645)).
+- Add support for `.yaml` extension (as an alternative to `.yml`).
+  This was requested multiple times throughout the years. Enjoy!
+  ([#183](https://github.com/go-task/task/issues/183), [#184](https://github.com/go-task/task/pull/184), [#369](https://github.com/go-task/task/issues/369), [#584](https://github.com/go-task/task/issues/584), [#621](https://github.com/go-task/task/pull/621)).
+- Fixed error when computing a variable when the task directory do not exist
+  yet
+  ([#481](https://github.com/go-task/task/issues/481), [#579](https://github.com/go-task/task/pull/579)).
+
+## v3.9.2 - 2021-12-02
+
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains a fix a for
+  a important regression on Windows
+  ([#619](https://github.com/go-task/task/issues/619), [mvdan/sh#768](https://github.com/mvdan/sh/issues/768), [mvdan/sh#769](https://github.com/mvdan/sh/pull/769)).
+
+## v3.9.1 - 2021-11-28
+
+- Add logging in verbose mode for when a task starts and finishes
+  ([#533](https://github.com/go-task/task/issues/533), [#588](https://github.com/go-task/task/pull/588)).
+- Fix an issue with preconditions and context errors
+  ([#597](https://github.com/go-task/task/issues/597), [#598](https://github.com/go-task/task/pull/598)).
+- Quote each `{{.CLI_ARGS}}` argument to prevent one with spaces to become many
+  ([#613](https://github.com/go-task/task/pull/613)).
+- Fix  nil pointer when `cmd:` was left empty
+  ([#612](https://github.com/go-task/task/issues/612), [#614](https://github.com/go-task/task/pull/614)).
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains two
+  relevant fixes:
+  - Fix quote of empty strings in `shellQuote`
+    ([#609](https://github.com/go-task/task/issues/609), [mvdan/sh#763](https://github.com/mvdan/sh/issues/763)).
+  - Fix issue of wrong environment variable being picked when there's another
+    very similar one
+    ([#586](https://github.com/go-task/task/issues/586), [mvdan/sh#745](https://github.com/mvdan/sh/pull/745)).

+
+## v3.9.0 - 2021-10-02
+
+- A new `shellQuote` function was added to the template system
+  (`{{shellQuote "a string"}}`) to ensure a string is safe for use in shell

+  - The `read -p` flag is now supported
+    ([#314](https://github.com/go-task/task/issues/314), [mvdan/sh#551](https://github.com/mvdan/sh/issues/551), [mvdan/sh#772](https://github.com/mvdan/sh/pull/722))
+  - The `pwd -P` and `pwd -L` flags are now supported
+    ([#553](https://github.com/go-task/task/issues/553), [mvdan/sh#724](https://github.com/mvdan/sh/issues/724), [mvdan/sh#728](https://github.com/mvdan/sh/pull/728))
+  - The `$GID` environment variable is now correctly being set
+    ([#561](https://github.com/go-task/task/issues/561), [mvdan/sh#723](https://github.com/mvdan/sh/pull/723))
+
+## v3.8.0 - 2021-09-26

+- Add ability to declare an included Taskfile as optional
+  ([#519](https://github.com/go-task/task/issues/519), [#552](https://github.com/go-task/task/pull/552)).
+- Add support for including Taskfiles in the home directory by using `~`
+  ([#539](https://github.com/go-task/task/issues/539), [#557](https://github.com/go-task/task/pull/557)).
+
+## v3.7.3 - 2021-09-04
+
+- Add official support to Apple M1 ([#564](https://github.com/go-task/task/pull/564), [#567](https://github.com/go-task/task/pull/567)).
+- Our [official Homebrew tap](https://github.com/go-task/homebrew-tap) will
+  support more platforms, including Apple M1
+
+## v3.7.0 - 2021-07-31
+
+- Add `run:` setting to control if tasks should run multiple times or not.
+  Available options are `always` (the default), `when_changed` (if a variable
+  modified the task) and `once` (run only once no matter what).
+  This is a long time requested feature. Enjoy!
+  ([#53](https://github.com/go-task/task/issues/53), [#359](https://github.com/go-task/task/pull/359)).
+
+## v3.6.0 - 2021-07-10
+
+- Allow using both `sources:` and `status:` in the same task
+  ([#411](https://github.com/go-task/task/issues/411), [#427](https://github.com/go-task/task/issues/427), [#477](https://github.com/go-task/task/pull/477)).
+- Small optimization and bug fix: don't compute variables if not needed for
+  `dotenv:` ([#517](https://github.com/go-task/task/issues/517)).
+
+## v3.5.0 - 2021-07-04
+
+- Add support for interpolation in `dotenv:`
+  ([#433](https://github.com/go-task/task/discussions/433), [#434](https://github.com/go-task/task/issues/434), [#453](https://github.com/go-task/task/pull/453)).
+
+## v3.4.3 - 2021-05-30
+
+- Add support for the `NO_COLOR` environment variable.
+  ([#459](https://github.com/go-task/task/issues/459), [fatih/color#137](https://github.com/fatih/color/pull/137)).
+- Fix bug where sources were not considering the right directory
+  in `--watch` mode
+  ([#484](https://github.com/go-task/task/issues/484), [#485](https://github.com/go-task/task/pull/485)).
+
+## v3.4.2 - 2021-04-23
+
+- On watch, report which file failed to read
+  ([#472](https://github.com/go-task/task/pull/472)).
+- Do not try to catch SIGKILL signal, which are not actually possible

+- Improve version reporting when building Task from source using Go Modules
+  ([#462](https://github.com/go-task/task/pull/462), [#473](https://github.com/go-task/task/pull/473)).
+
+## v3.4.1 - 2021-04-17
+
+- Improve error reporting when parsing YAML: in some situations where you
+  would just see an generic error, you'll now see the actual error with
+  more detail: the YAML line the failed to parse, for example
+  ([#467](https://github.com/go-task/task/issues/467)).
+- A JSON Schema was published [here](https://json.schemastore.org/taskfile.json)
+  and is automatically being used by some editors like Visual Studio Code
+  ([#135](https://github.com/go-task/task/issues/135)).
+- Print task name before the command in the log output
+  ([#398](https://github.com/go-task/task/pull/398)).
+
+## 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)).
+- 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))
+- 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

+# Community
+
+Some of the work to improve the Task ecosystem is done by the community, be
+it installation methods or integrations with code editor. I (the author) am
+thankful for everyone that helps me to improve the overall experience.
+
+## Editor Integrations
+
+### JSON Schema
+
+[@KROSF](https://github.com/KROSF) worked on a JSON Schema [into this Gist](https://gist.github.com/KROSF/c5435acf590acd632f71bb720f685895),
+which later was made officially available by [@Crandel](https://github.com/Crandel)
+at [https://json.schemastore.org/taskfile.json](https://json.schemastore.org/taskfile.json).
+Further improvements are possible by opening pull requests changing
+[this file](https://github.com/SchemaStore/schemastore/blob/master/src/schemas/json/taskfile.json).
+Some code editors, like Visual Studio Code, make use of Schema Store
+automatically.
+
+### Visual Studio Code extension
+
+Additionally, there's also some work done by
+[@paulvarache](https://github.com/paulvarache) in making an Visual Studio Code
+extension, which has its code [here](https://github.com/paulvarache/vscode-taskfile)
+and is published [here](https://marketplace.visualstudio.com/items?itemName=paulvarache.vscode-taskfile).
+
+### Sublime Text 4 package
+
+There is a convenience wrapper for initializing and running tasks from Sublime Text's command palette. The package is
+developed by [@biozz](https://github.com/biozz), the source code is available [here](https://github.com/biozz/sublime-taskfile)
+and it is published on Package Control [here](https://packagecontrol.io/packages/Taskfile).
+
+### IntelliJ plugin
+
+There's a JetBrains IntelliJ plugin done by
+[@lechuckroh](https://github.com/lechuckroh), which has its code [here](https://github.com/lechuckroh/task-intellij-plugin)
+and is published [here](https://plugins.jetbrains.com/plugin/17058-taskfile).
+
+## Installation methods
+
+Some installation methods are maintained by third party:
+
+- [GitHub Actions](https://github.com/arduino/setup-task)
+  by [@arduino](https://github.com/arduino)
+- [AUR](https://aur.archlinux.org/packages/go-task-bin)
+  by [@carlsmedstad](https://github.com/carlsmedstad)
+- [Scoop](https://github.com/lukesampson/scoop-extras/blob/master/bucket/task.json)

+
+# Contributing
+
+Contributions to Task are very welcome, but we ask that you read this document
+before submitting a PR.
+
+## 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 you time into a PR.
+
+## 1. Setup
+
+- **Go** - Task is written in [Go]. We always support the latest two major Go
+  versions, so make sure your version is recent enough.
+- **Node.js** - [Node.js] is used to host Task's documentation server and is
+  required if you want to run this server locally.
+- **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 and
+  ensure that code is formatted by `gofmt`. We use `golangci-lint` in our CI to
+  enforce a consistent style and best-practise. There's a `lint` command in
+  the Taskfile to run this locally.
+- **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>`.
+
+### Updating documentation
+
+Task uses [Docusaurus] to host a documentation server. This can be setup and run
+locally by using `task docs:setup` and `task docs:start` respectively (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.
+
+When making a change, consider whether a change to the [Usage Guide](./usage.md)
+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.md).
+
+If you added a new command/flag, ensure that you add it to the [API
+Reference](./api_reference.md).
+
+### Writing tests
+
+Most of Task's test 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
+behaviour.
+
+## 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!
+
+## 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 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

+simpler issues that are ideal for first time contributions.

+
+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:
+
+```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
+```
+
+### Chocolatey
+
+If you're on Windows and have [Chocolatey][choco] installed, getting
+Task is as simple as running:
+
+```bash
+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:
+
+```cmd
+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`:
+
+```cmd
+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):
+
+```cmd
+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`:
+
+```cmd
+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):
+
+```cmd
+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).
+
+```bash
+npm install -g @go-task/cli
+```
+
+## Get The Binary
+
+### Binary
+
+You can download the binary from the [releases page on GitHub][releases] and
+add to your `$PATH`.
+
+DEB and RPM packages are also available.
+
+The `task_checksums.txt` file contains the SHA-256 checksum for each file.
+
+### Install Script
+
+We also have an [install script][installscript] which is very useful in
+scenarios like CI. Many thanks to [GoDownloader][godownloader] for enabling the
+easy generation of this script.
+
+By default, it installs on the `./bin` directory relative to the working
+directory:
+
+```bash
+sh -c "$(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:
+

+
+### 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
+```
+
+This installation method is community owned.
+
+## Build From Source
+
+### Go Modules
+
+First, make sure you have [Go][go] properly installed and setup.
+
+You can easily install the latest release globally by running:
+
+```bash
+go install github.com/go-task/task/v3/cmd/task@latest
+```
+
+Or you can install into another directory:
+
+```bash
+env GOBIN=/bin go install github.com/go-task/task/v3/cmd/task@latest
+```
+
+If using Go 1.15 or earlier, instead use:
+
+```bash
+env GO111MODULE=on go get -u github.com/go-task/task/v3/cmd/task@latest
+```
+
+:::tip
+
+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.

+# 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 master
+(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].
+
+# 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/lukesampson/scoop-extras/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).

+# 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 they don't necessarily need to be strictly
+followed. Feel free to disagree and proceed differently at 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:`, `silent:`, `method:` and `run:`
+- `vars:`
+- `env:`, `dotenv:`
+- `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
+vars:
+  FOO: bar
+env:
+  BAR: baz

+
+output: prefixed
+
+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:

+  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.

+## 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!"
+```
+
+- 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

-# Installation
-
-## Binary
-
-Or you can download the binary from the [releases][releases] page and add to
-your $PATH. DEB and RPM packages are also available.
-The `task_checksums.txt` file contains the sha256 checksum for each file.
-
-## Homebrew
-
-If you're on macOS and have [Homebrew][homebrew] installed, getting Task is
-as simple as running:
-
-```bash
-brew install go-task/tap/go-task
-```
-
-## Snap
-
-Task is available for [Snapcraft][snapcraft], but keep in mind that your
-Linux distribution should allow classic confinement for Snaps to Task work
-right:
-
-```bash
-sudo snap install task
-```
-
-## Scoop
-
-If you're on Windows and have [Scoop][scoop] installed, use `extras` bucket
-to install Task like:
-
-```cmd
-scoop bucket add extras
-scoop install task
-```
-
-This installation method is community owned. After a new release of Task, it
-may take some time until it's available on Scoop.
-
-## Go
-
-Task now uses [Go Modules](https://github.com/golang/go/wiki/Modules), which
-means you may have trouble compiling it on older Go versions.
-
-For CI environments we recommend using the [Install Script](#install-script)
-instead, which is faster and more stable, since it'll just download the latest
-released binary, instead of compiling the edge (master branch) version.
-
-Installing in your `$GOPATH`:
-
-```bash
-go get -u -v github.com/go-task/task/cmd/task
-```
-
-Installing in another directory:
-
-```bash
-git clone https://github.com/go-task/task
-cd task
-
-# compiling binary to $GOPATH/bin
-go install -v
-
-# compiling it to another location
-# use -o ./task.exe on Windows
-go build -v -o ./task ./cmd/task
-```
-
-Both methods requires having the [Go][go] environment properly setup locally.
-
-## 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
-curl -s https://taskfile.org/install.sh | sh
-```
-
-> This method will download the binary on the local `./bin` directory by default.

-# Releasing Task
-
-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.
-
-The Travis CI should release automatically when a new
-Git tag is pushed to master, either for the artifact uploading (raw executables
-and DEB and RPM packages)
-
-# Homebrew
-
-To release a new version on the [Homebrew tap][homebrewtap] edit the
-[Formula/go-task.rb][gotaskrb] file, updating with the new version, download
-URL and sha256.
-
-# Snapcraft
-
-The exception is the publishing of a new version of the
-[snap package][snappackage]. This current require two steps after publishing
-the binaries:
-
-* Updating the current version on [snapcraft.yaml][snapcraftyaml];
-* Moving both `i386` and `amd64` new artifacts to the stable channel on
-the [Snapcraft dashboard][snapcraftdashboard]
-
-# Scoop
-
-Scoop is a community owned installation method. Scoop owners usually take care
-of updating versions there by editing
-[this file](https://github.com/lukesampson/scoop-extras/blob/master/task.json).
-If you think its Task version is outdated, open an issue to let us know.

-# 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: '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` 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
-
-You can use `env` to set custom environment variables for a specific task:
-
-```yaml
-version: '2'
-
-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: '2'
-
-env:
-  GREETING: Hey, there!
-
-tasks:
-  greet:
-    cmds:
-      - echo $GREETING
-```
-
-> NOTE: `env` supports expansion and and retrieving output from a shell command
-> just like variables, as you can see on the [Variables](#variables) section.
-
-## Operating System specific tasks
-
-If you add a `Taskfile_{{GOOS}}.yml` you can override or amend your Taskfile
-based on the operating system.
-
-Example:
-
-Taskfile.yml:
-
-```yaml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo "default"
-```
-
-Taskfile_linux.yml:
-
-```yaml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo "linux"
-```
-
-Will print out `linux` and not `default`.
-
-Keep in mind that the version of the files should match. Also, when redefining
-a task the whole task is replaced, properties of the task are not merged.
-
-It's also possible to have an OS specific `Taskvars.yml` file, like
-`Taskvars_windows.yml`, `Taskvars_linux.yml`, or `Taskvars_darwin.yml`. See the
-[variables section](#variables) below.
-
-## Including other Taskfiles
-
-> This feature is still experimental and may have bugs.
-
-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: '2'
-
-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.
-
-> 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: '2'
-
-tasks:
-  serve:
-    dir: public/www
-    cmds:
-      # run http server
-      - caddy
-```
-
-## Task dependencies
-
-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: '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:
-
-```yaml
-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 is 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):
-
-```yaml
-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:
-
-```yaml
-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:
-
-```yaml
-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`.
-
-> 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
-
-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: '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).
-
-```yaml
-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:
-
-```yaml
-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 a non-zero exit code if any of
-the tasks are 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:
-
-```yaml
-version: '2'
-
-tasks:
-  print-var:
-    cmds:
-      echo "{{.VAR}}"
-    vars:
-      VAR: Hello!
-```
-
-Example of global vars in a `Taskfile.yml`:
-
-```yaml
-version: '2'
-
-vars:
-  GREETING: Hello from Taskfile!
-
-tasks:
-  greet:
-    cmds:
-      - echo "{{.GREETING}}"
-```
-
-Example of `Taskvars.yml` file:
-
-```yaml
-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:
-
-```yaml
-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.
-
-```yaml
-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:
-
-```yaml
-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`: 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: '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:
-
-```yaml
-version: '2'
-
-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.
-```
-
-## Silent mode
-
-Silent mode disables echoing of commands before Task runs it.
-For the following Taskfile:
-
-```yaml
-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:
-
-```yaml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - cmd: echo "Print something"
-        silent: true
-```
-
-* At task level:
-
-```yaml
-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`:
-
-```yaml
-version: '2'
-
-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: '2'
-
-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: '2'
-
-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: '2'
-
-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: '2'
-
-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.
-
-## Watch tasks
-
-If you give a `--watch` or `-w` argument, task will watch for file changes
-and run the task again. This requires the `sources` attribute to be given,
-so task know which files to watch.
