Runfile - command line for your projects

A beautiful command line utility builder
Rake-inspired ✦ Docopt inside
runfile.dannyb.co

Runfile lets you create command line tools in a way similar to Rake, but with the full power of Docopt command line options.

You create a runfile, and execute commands with run command arguments -and --flags.

Runfile is designed primarily for Ruby developers, but if you need to add a command line "toolbelt" for your projects, you can use it regardless.

Demo

Install

$ gem install runfile --pre

Quick Start

$ run new        # create a new runfile
$ run --help     # show the usage patterns
$ vi runfile     # edit the runfile

Example

A simple runfile looks like this. You can get this template by running run new (in a directory without other runfiles).

title   'Greeter'
summary 'A sample runfile'

usage  'hello [NAME --shout]'
help   'Say hello'
option '--shout, -s', 'Greet louder'
action 'hello' do |args|
  name = args['NAME'] || 'You...'
  message = "Hello #{name}"
  message = "#{message.upcase}!" if args['--shout']

  say "gu`#{message}`"
end

You can then run it by executing this command:

$ run hello Luke
Hello Luke

It will behave in the same way you expect any standard command line interface to behave,

# Show usage summary
$ run
Usage:
  run hello [NAME --shout]
  run (--help | -h)

# Show detailed help
$ run --help
Greeter

  A sample runfile

Usage:
  run hello [NAME --shout]
  run (--help | -h)

Commands:
  hello
    Say hello

Options:
  --shout, -s
    Greet louder

    Show this message
