Run all your project-related scripts in a portable, simple config.

Dart Script Runner

A general script runner for any type of project - run all your project-related scripts and commands in a portable, simple config.

script_runner help output


What for? #

You might use it to chain multiple commands into a unified build process, format and lint your documents, or more.

The advantage over make is that this is auto documented, and will automatically load your scripts from the directory that contains pubspec.yaml, instead of having to find the root project dirctory manually.

This project was developed with inspiration from NPM's scripts inside package.json and is meant to work similarly, though it can be customized to fit your needs more specifically.

Features #

  • Easy: Provides an easy to use config for project-related scripts, similar to what NPM allows in its scripts section of package.json.
  • Portable: The scripts are meant to be portable and can reference each-other, to maximize the flexibility of creating configurable script execution orders & dependencies. Also you don't have to be on a dart project, just add a script_runner.yaml file to any folder and you're good to go!
  • Self-documenting: Removes the need to document where and how to load different types of scripts on your project, or create custom script loaders and more time-wasting pipeline. Unify all your runners into 1 config that lets you freely call everything on-demand from any type of project, and also supply an auto-generated documentation using scr -h.

Getting started #

You can install this package globally for the most easy usage.

pub global activate script_runner

Once activated, you can use the supplied scr executable to directly call scripts from any project you are currently in.

scr my-script ...args

You can also install this package as a dependency and build/run your own script lists. (but why would you?)

Built-in Commands #

To get help, including the list of all scripts available in the current directory, run:

scr -h

To list all the scripts, with the ability to search, use:

scr -ls # see all
scr -ls terms # search for "terms"

Usage #

Normal usage (config file) #

Add the script_runner config to your pubspec.yaml under script_runner, or alternatively you can use a separate config file named script_runner.yaml at the root of your project.

If you are using a separate file, you may also use JSON instead of YAML, if you prefer.

A bare-bones example looks like this:

script_runner:
  scripts:
    - doc: dart doc
    - publish: dart pub publish
    - deploy: doc && publish
    - auto-fix: dart fix --apply

This is the full structure of a config:

# only use this key if you are inside pubspec.yaml. Otherwise, it's not needed
script_runner:
  # The shell to run all of the scripts with. (optional - defaults to OS shell)
  shell: /bin/sh
  # Use a map to define shell per OS, when not specified falls back to "default":
  # (optional)
  shell:
    default: /bin/sh
    windows: cmd.exe
    macos: /bin/sh
    linux: /bin/sh
  # The current working directory to run the scripts in. (optional)
  cwd: .
  # Environment variables to add to the running shells in the scripts. (optional)
  env:
    MY_ENV: my-value
    # ...
  # The amount of characters to allow before considering the line over when
  # printing help usage (scr -h)
  line_length: 80
  # Scripts support either a short-format config, or a more verbose one with
  # more possible argument to pass to each script.
  # Scripts are aliased for the current, e.g. `script1` can reference
  # `script2` by calling it directly in the command:
  # - script1: echo '1'
  # - name: script2
  #   cmd: script1 && echo '2'
  # Running `script1` will echo 1 and then 2.
  scripts:
    # short format - only name + cmd & args:
    - my-short-script: my_scr arg1 arg2 arg3 && echo 'Done!'

    # more verbose config, for extra configuration
    - name: my-script
      # Optional - will be used in docs when using `scr -h`.
      description: Run my script
      # Optional - overrides the root-level config
      cwd: .
      # Optional - overrides the root-level config
      env:
        MY_ENV: my-value
        # ...
      # Use `false` to hide the command itself before running it.
      # This is useful for using the output in other scripts (scr or external)
      # Defaults to true
      display_cmd: true
      # The script to run. You can supply the args directly here, or split into
      # `cmd` and `args` as a list.
      cmd: my_scr 'arg1'
      # Optional - if supplied, will be appended as arguments to `cmd`, before the args passed
      # by calling the script from the CLI
      args:
        - arg2
        - arg3

For this config, running scr my-script will run the appropriate script, filling the env and changing the working directory as needed.

More arguments can be passed during the call to the script, which will then be piped to the original cmd.

Advanced usage (Dart import) #

If you want to build your own configs dynamically in Dart, you can import the package and create your own runners and scripts:

import 'package:script_runner/script_runner.dart';

void main() {
  // Directly run a script from config, same as running `scr`
  runScript('my-script', ['arg1', 'arg2'])

  // Build your own configurations and scripts and run them as you please:
  final runner = ScriptRunnerConfig(
    shell: '/bin/zsh',
    scripts: [
      RunnableScript(
        name: 'my-script',
        cmd: 'echo',
        args: ['Hello world'],
      ),
    ],
  );

  runner.scriptsMap['my-script'].run();
}
