Experiment to make single-file dart scripts more accessible as ordinary scripts.

dartfn

dartfn is a simple experiment to make single-file dart scripts more accessible as ordinary scripts. This leverages oh-my-zsh plugins to be able to execute dart programs.

Requirements:

• Have zsh and oh-my-zsh installed.
• Have dart SDK installed.

Installing:

1. Clone this repo any where on your machine
2. Copy/move the dart-functions directory and it's contents into $ZSH_CUSTOM/plugins the full path for may look like /Users/some-user/.oh-my-zsh/custom/plugins/dart-functions/dart-functions.plugin.zsh
3. In your .zshrc
   • set DART_FUNCTIONS to the folder/directory that will hold your dart scripts
   • update your plugins=( dart-functions )
4. Run exec zsh to update your environment.

Usage

No you can add .dart files to the $DART_FUNCTIONS directory. If you create a $DART_FUNCTIONS/hello.dart that is:

void main(List<String> args) {
  print('Hi, mom!');
  print('length: ${args.length}');
  print('args: $args');
}

You can now run it by pre-fixing the file name (less the .dart extension) with dfn.

$ dfn hello
Hi, mom!
length: 0
args: []

Argument after the file name are forwarded to the dart script arguments:

$ dfn hello this is "several args"
Hi, mom!
length: 3
args: [this, is, several args]

Caveats

• Dart file with whitespace must be called with enclosing ". For example: dfn "hello world" will execute $DART_FUNCTIONS/hello\ world.dart
