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

-# Task
-
-Task is a task runner / build tool that aims to be simpler and easier to use
-than, for example, [GNU Make][make].
-
-Since it's written in [Go][go], Task is just a single binary and has no other
-dependencies, which means you don't need to mess with any complicated install
-setups just to use a build tool.
-
-Once [installed](installation.md), you just need to describe your build tasks
-using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
-
-```yaml
-version: '2'
-
-tasks:
-  hello:
-    cmds:
-      - echo 'Hello World from Task!'
-    silent: true
-```
-
-And call it by running `task hello` from you terminal.
-
-The above example is just the start, you can take a look at the [usage](usage.md)
-guide to check the full schema documentation and Task features.
-
-## Features
-
-- [Easy installation](installation.md): just download a single binary, add to
-  $PATH and you're done! Or you can also install using [Homebrew][homebrew],
-  [Snapcraft][snapcraft], or [Scoop][scoop] if you want;
-- Available on CIs: by adding [this simple command](installation.md#install-script)
-  to install on your CI script and you're done to use Task as part of your CI pipeline;
-- Truly cross-platform: while most build tools only work well on Linux or macOS,
-  Task also supports Windows thanks to [this awesome shell interpreter for Go][sh];
-- Great for code generation: you can easily [prevent a task from running](usage.md#prevent-unnecessary-work)
-  if a given set of files haven't changed since last run (based either on its
-  timestamp or content).

-# Installation
-
-## Binary
-
-Or you can download the binary from the [releases][releases] page and add to
-your $PATH. DEB and RPM packages are also available.
-The `task_checksums.txt` file contains the sha256 checksum for each file.
-
-## Homebrew
-
-If you're on macOS or Linux and have [Homebrew][homebrew] installed, getting
-Task is as simple as running:
-
-```bash
-brew install go-task/tap/go-task
-```
-
-> This installation method is only currently supported on amd64 architectures.
-
-## Snap
-
-Task is available for [Snapcraft][snapcraft], but keep in mind that your
-Linux distribution should allow classic confinement for Snaps to Task work
-right:
-
-```bash
-sudo snap install task
-```
-
-## Scoop
-
-If you're on Windows and have [Scoop][scoop] installed, use `extras` bucket
-to install Task like:
-
-```cmd
-scoop bucket add extras
-scoop install task
-```
-
-This installation method is community owned. After a new release of Task, it
-may take some time until it's available on Scoop.
-
-## Go
-
-Task now uses [Go Modules](https://github.com/golang/go/wiki/Modules), which
-means you may have trouble compiling it on older Go versions or using
-`$GOPATH`.
-
-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 another directory:
-
-```bash
-git clone https://github.com/go-task/task
-cd task
-
-# compiling binary to $GOPATH/bin
-go install -v ./cmd/task
-
-# compiling it to another location
-# use -o ./task.exe on Windows
-go build -v -o ./task ./cmd/task
-```
-
-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 -sL https://taskfile.dev/install.sh | sh
-```
-
-> This method will download the binary on the local `./bin` directory by default.
-
-## GitHub Actions
-
-If you want to install Task in GitHub Actions you can try using
-[this action](https://github.com/arduino/actions/tree/master/setup-taskfile)
-by the Arduino team:
-
-```yaml
-- name: Install Task
-  uses: Arduino/actions/setup-taskfile@master
-```
-
-This installation method is community owned.

-# Styleguide
-
-This is the official Task styleguide for `Taskfile.yml` files. This guide
-contains some basic instructions to keep your Taskfile clean and familiar to
-other users.
-
-This contains general guidelines, but don't necessarely need to be strictly
-followed. Feel free to disagree and proceed differently in some point if you
-need or want to. Also, feel free to open issues or pull requests with
-improvements to this guide.
-
-## Use `Taskfile.yml` and not `taskfile.yml`
-
-```yaml
-# bad
-taskfile.yml
-
-
-# good
-Taskfile.yml
-```
-
-This is important especially for Linux users. Windows and macOS have case
-insensitive filesystems, so `taskfile.yml` will end up working, even that not
-officially supported. On Linux, only `Taskfile.yml` will work, though.
-
-## Use the correct order of keywords
-
-- `version:`
-- `includes:`
-- Configuration ones, like `output:`, `expansions:` or `silent:`
-- `vars:`
-- `env:`
-- `tasks:`
-
-## Use 2 spaces for indentation
-
-This is the most common convention for YAML files, and Task follows it.
-
-```yaml
-# bad
-tasks:
-    foo:
-        cmds:
-            - echo 'foo'
-
-
-# good
-tasks:
-  foo:
-    cmds:
-      - echo 'foo'
-```
-
-## Separate with spaces the mains sections
-
-```yaml
-# bad
-version: 2
-includes:
-  docker: ./docker/Taskfile.yml
-output: prefixed
-expansions: 3
-vars:
-  FOO: bar
-env:
-  BAR: baz
-tasks:
-  # ...
-
-
-# good
-version: 2
-
-includes:
-  docker: ./docker/Taskfile.yml
-
-output: prefixed
-expansions: 3
-
-vars:
-  FOO: bar
-
-env:
-  BAR: baz
-
-tasks:
-  # ...
-```
-
-## Add spaces between tasks
-
-```yaml
-# bad
-version: 2
-
-tasks:
-  foo:
-    cmds:
-      - echo 'foo'
-  bar:
-    cmds:
-      - echo 'bar'
-  baz:
-    cmds:
-      - echo 'baz'
-
-
-# good
-version: 2
-
-tasks:
-  foo:
-    cmds:
-      - echo 'foo'
-
-  bar:
-    cmds:
-      - echo 'bar'
-
-  baz:
-    cmds:
-      - echo 'baz'
-```
-
-## Use upper-case variable names
-
-```yaml
-# bad
-version: 2
-
-vars:
-  binary_name: myapp
-
-tasks:
-  build:
-    cmds:
-      - go build -o {{.binary_name}} .
-
-

-# 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 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
-```
-
-If the directory doesn't exist, `task` creates it.
-
-## 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.
-
-> You can also make the tasks given by the command line run in parallel by
-> using the `--parallel` flag (alias `-p`). Example: `task --parallel js css`.
-
-If you want to pass information to dependencies, you can do that the same
-manner as you would to [call another task](#calling-another-task):
-
-```yaml
-version: '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.
-
-If you need a certain set of conditions to be _true_ you can use the
-`preconditions` stanza.  `preconditions` are very 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:
-    preconditions:
-      - sh: "exit 1"
-
-  task_will_also_fail:
-    deps:
-      - task_will_fail
-
-  task_will_still_fail:
-    cmds:
-      - task: task_will_fail
-      - echo "I will not run"
-```
-
-## Variables
-
-When doing interpolation of variables, Task will look for the below.
-They are listed below in order of importance (e.g. most important first):
-
-- Variables declared in the task definition
-- Variables given while calling a task from another.
-  (See [Calling another task](#calling-another-task) above)
-- 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!"
-```
-
-If you want to set global variables using this syntax, give it before any task:
-
-```bash
-$ task OUTPUT=file.txt generate-file
-```
-
-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.
-```
-
-## Display summary of task
-
-Running `task --summary task-name` will show a summary of a task
-The following Taskfile:
-
-```yaml
-version: '2'
-
-tasks:
-  release:
-    deps: [build]
-    summary: |
-      Release your project to github
-
-      It will build your project before starting the release it.
-      Please make sure that you have set GITHUB_TOKEN before starting.
-    cmds:
-      - your-release-tool
-
-  build:
-    cmds:
-      - your-build-tool
-```
-
-with running ``task --summary release`` would print the following output:
-
-```
-task: release
-
-Release your project to github
-
-It will build your project before starting the release it.
-Please make sure that you have set GITHUB_TOKEN before starting.
-
-dependencies:
- - build
-
-commands:
- - your-release-tool
-```
-If a summary is missing, the description will be printed.
-If the task does not have a summary or a description, a warning is printed.
-
-Please note: *showing the summary will not execute the command*.
-
-## 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 are four 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
-```
-
-* Globally at Taskfile level:
-
-```yaml
-version: '2'
-
-silent: true
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-```
-
-* Or globally with `--silent` or `-s` flag
-
-If you want to suppress STDOUT instead, just redirect a command to `/dev/null`:
-
-```yaml
-version: '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.
