CLI

O comando "task" tem a seguinte sintaxe:

task [--flags] [tasks...] [-- CLI_ARGS...]

dica

Se -- é informado, todos os argumentos remanescentes serão atribuídos a uma variável especial chamada CLI_ARGS

Códigos de saída

O Task às vezes fecha com códigos de saída específicos. Estes códigos são divididos em três grupos com os seguintes intervalos:

• Erros gerais (0-99)
• Erros de Taskfile (100-199)
• Erros de execução de tarefa (200-299)

Uma lista completa dos códigos de saída e suas descrições podem ser encontradas abaixo:

Código	Descrição
0	Sucesso
1	Um erro desconhecido ocorreu
100	Nenhum Arquivo foi encontrado
101	Um arquivo Taskfile já existe ao tentar inicializar um
102	O arquivo Taskfile é inválido ou não pode ser analisado
200	A tarefa especificada não pôde ser encontrada
201	Ocorreu um erro ao executar um comando dentro de uma tarefa
202	O usuário tentou invocar uma tarefa que é interna
203	Há várias tarefas com o mesmo nome ou apelido
204	Uma tarefa foi chamada muitas vezes

Esses códigos também podem ser encontrados no repositório em errors/errors.go.

info

When Task is run with the -x/--exit-code flag, the exit code of any failed commands will be passed through to the user instead.

Saída em JSON

Quando estiver usando o modificador --json em combinação com o modificador --list ou --list-all, a saída será um objeto JSON com a seguinte estrutura:

{
  "tasks": [
    {
      "name": "",
      "desc": "",
      "summary": "",
      "up_to_date": false,
      "location": {
        "line": 54,
        "column": 3,
        "taskfile": "/path/to/Taskfile.yml"
      }
    }
    // ...
  ],
  "location": "/path/to/Taskfile.yml"
}

Taskfile Schema

Attribute	Type	Default	Description
version	string		Version of the Taskfile. The current version is 3.
output	string	interleaved	Output mode. Available options: interleaved, group and prefixed.
method	string	checksum	Default method in this Taskfile. Can be overriden in a task by task basis. Available options: checksum, timestamp and none.
includes	map[string]Include		Additional Taskfiles to be included.
vars	map[string]Variable		A set of global variables.
env	map[string]Variable		A set of global environment variables.

run	string	always	Default 'run' option for this Taskfile. Available options: always, once and when_changed.
interval	string	5s	Sets a different watch interval when using --watch, the default being 5 seconds. This string should be a valid Go Duration.
set	[]string		Specify options for the set builtin.
shopt	[]string		Specify option for the shopt builtin.

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.
dir	string	The parent Taskfile directory	The working directory of the included tasks when run.
optional	bool	false	If true, no errors will be thrown if the specified file does not exist.
internal	bool	false	Stops any task in the included Taskfile from being callable on the command line. These commands will also be omitted from the output when used with --list.
aliases	[]string		Alternative names for the namespace of the included Taskfile.
vars	map[string]Variable		A set of variables to apply to the included Taskfile.

info

Informing only a string like below is equivalent to setting that value to the taskfile attribute.

includes:
  foo: ./path

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:

vars:
  STATIC: static
  DYNAMIC:
    sh: echo "dynamic"

Task

Attribute	Type	Default	Description
cmds	[]Command		A list of shell commands to be executed.
deps	[]Dependency		A list of dependencies of this task. Tasks defined here will run in parallel before this task.
label	string		Overrides the name of the task in the output when a task is run. Supports variables.
desc	string		A short description of the task. This is displayed when calling task --list.
summary	string		A longer description of the task. This is displayed when calling task --summary [task].
aliases	[]string		A list of alternative names by which the task can be called.
sources	[]string		A list of sources to check before running this task. Relevant for checksum and timestamp methods. Can be file paths or star globs.
generates	[]string		A list of files meant to be generated by this task. Relevant for timestamp method. Can be file paths or star globs.
status	[]string		A list of commands to check if this task should run. The task is skipped otherwise. This overrides method, sources and generates.
preconditions	[]Precondition		A list of commands to check if this task should run. If a condition is not met, the task will error.
dir	string		The directory in which this task should run. Defaults to the current working directory.
vars	map[string]Variable		A set of variables that can be used in the task.
env	map[string]Variable		A set of environment variables that will be made available to shell commands.
dotenv	[]string		A list of .env file paths to be parsed.
silent	bool	false	Hides task name and command from output. The command's output will still be redirected to STDOUT and STDERR. When combined with the --list flag, task descriptions will be hidden.
interactive	bool	false	Tells task that the command is interactive.
internal	bool	false	Stops a task from being callable on the command line. It will also be omitted from the output when used with --list.
method	string	checksum	Defines which method is used to check the task is up-to-date. timestamp will compare the timestamp of the sources and generates files. checksum will check the checksum (You probably want to ignore the .task folder in your .gitignore file). none skips any validation and always run the task.
prefix	string		Defines a string to prefix the output of tasks running in parallel. Only used when the output mode is prefixed.
ignore_error	bool	false	Continue execution if errors happen while executing commands.
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.
platforms	[]string	All platforms	Specifies which platforms the task should be run on. Valid GOOS and GOARCH values allowed. Task will be skipped otherwise.
set	[]string		Specify options for the set builtin.
shopt	[]string		Specify option for the shopt builtin.

info

These alternative syntaxes are available. They will set the given values to cmds and everything else will be set to their default values:

tasks:
  foo: echo "foo"

  foobar:
    - echo "foo"
    - echo "bar"

  baz:
    cmd: echo "baz"

Command

Attribute	Type	Default	Description
cmd	string		The shell command to be executed.
silent	bool	false	Skips some output for this command. Note that STDOUT and STDERR of the commands will still be redirected.
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		Optional additional variables to be passed to the referenced task. Only relevant when setting task instead of cmd.
ignore_error	bool	false	Continue execution if errors happen while executing the command.
defer	string		Alternative to cmd, but schedules the command to be executed at the end of this task instead of immediately. This cannot be used together with cmd.
platforms	[]string	All platforms	Specifies which platforms the command should be run on. Valid GOOS and GOARCH values allowed. Command will be skipped otherwise.
set	[]string		Specify options for the set builtin.
shopt	[]string		Specify option for the shopt builtin.

info

If given as a a string, the value will be assigned to cmd:

tasks:
  foo:
    cmds:
      - echo "foo"
      - echo "bar"

Dependency

Attribute	Type	Default	Description
task	string		The task to be execute as a dependency.
vars	map[string]Variable		Optional additional variables to be passed to this task.
silent	bool	false	Hides task name and command from output. The command's output will still be redirected to STDOUT and STDERR.

dica

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):

tasks:
  foo:
    deps: [foo, bar]

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.

dica

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:

tasks:
  foo:
    precondition: test -f Taskfile.yml
