Getting Started #

To start using strike_cli, run pub global activate strike_cli.

Tasks may be run by running strike <task_name>.

Defining Tasks #

To define a task, create a strike.yaml file in the root of your project. This file will be where you configure your tasks and how they are run. The most basic task you can define is simply an alias for a command. For example, if you wanted to define a task that runs dart pub get, you could do so like this:

tasks:
  get:
    info: "fetch dependencies"

    name: "Fetching Dependencies"
    run: "dart pub get"

However this isn't so useful by itself. It becomes more useful when you wish to run multiple commands in sequence. Lets say you wanted to run dart pub get and then dart test:

tasks:
  get_and_test:
    info: "run tests"

    name: "Running Tests"
    steps:
      - run: "dart pub get"
      - name: "Named step"
        run: "dart test"

You can also reference other tasks by using task:<task_name> instead of a command.

Targets #

Targets are a way to define a set of tasks that can be run in multiple packages. This helps when you have a large project with many packages. For example, if you wanted to run dart pub get all directories within packages/, you could do so by defining a target for all packages. Then you can define a task that runs dart pub get for all packages.

targets:
  packages: packages/*

  # You can also define multiple patterns for a single target
  packages:
    - packages/*
    - third_party/*

tasks:
    get:
        info: "fetch dependencies"

        name: "Fetching Dependencies"
        run: "dart pub get"
        targets: target:packages
        # You also have the option of listing the targets directly
        # targets: packages/*

Your targets may also reference other targets.

targets:
  packages: packages/*

  all:
    - target:packages
    - foobar/

You also have the option of filtering targets. Currently, only the file_exists filter is supported. This filter will only include targets that have a file that matches the given pattern.

targets:
  packages: packages/*

  # Only include packages with a `build.yaml` file
  build_runner:
    for:
      - packages/*
    # Or use the shorthand syntax, referencing an existing target definition
    # for: target:packages

    filter:
      - type: file_exists
        glob: build.yaml

Concurrency #

Running commands sequentially for all of your targets can take a long time. To help with this, you can run commands concurrently. To do so, simply add concurrency to define how many commands to execute at once.

tasks:
  get:
    info: "fetch dependencies"

    name: "Fetching Dependencies"
    run: "dart pub get"
    concurrency: 4
    targets: target:packages

Arguments #

Tasks can also accept arguments. The args section is a map of argument names to their default values. You can then access these arguments in your task definition using the args variable.

tasks:
  integration:
    info: "run integration tests"

    args:
      - name: device
        info: "device to run tests on"
        type: string
        default: null

    run: "flutter test integration_test ${args['device'] ? '-d ${args['device']}' : ''}"
    target: target:app

Conditional Steps #

You can also conditionally run steps. This is useful when you want to run a step only if a certain condition is met.

tasks:
  foo:
    info: "bla bla bla"

    condition: "platform != 'macos'"
    if:
      - run: "echo 'macos'"
    # Shorthands also work
    else: "echo 'not macos'"

  bar:
    info: "bla bla bla"

    steps:
      - if: "platform != 'macos'"
        name: "namenamename"
        run: "echo 'macos'"
      - "echo 'always runs'"

Nested Steps #

You can also nest steps within steps. This is occasionally useful.

tasks:
  foo:
    info: "bla bla bla"

    steps:
      - run: "echo 'foo'"
      - steps:
          - run: "echo 'bar'"
          - run: "echo 'baz'"
      - run: "echo 'qux'"
