ChordPro for Ruby

ChordPro is a text format for transcribing songs.

This project is a Ruby Gem that converts the song into a Song data model which can then be converted into various output formats such as text or HTML.

Installation

Add this line to your application's Gemfile:

gem 'song_pro'

And then execute:

$ bundle

Or install it yourself as:

$ gem install chord_pro

Usage

Given then file bad-moon-rising.pro with the following contents:

{title:Bad Moon Rising}
{artist:Cleedence Clearwater Revival}

{start_of_grid:Intro}
| [D] | [A] [G] | [D] |
{end_of_grid}

{start_of_verse}
[D]I see a [A]bad [G]moon a-[D]rising
[D]I see [A]trouble [G]on the [D]way
[D]I see [A]earth-[G]quakes and [D]lightnin'
[D]I see [A]bad [G]times to-[D]day
{end_of_verse}

You can then parse the file to create a Song object:

require 'song_pro'

text = File.read('bad-moon-rising.pro')
song = ChordPro.parse(text)

puts song.title
# Bad Moon Rising

puts song.artist
# Creedence Clearwater Revival

puts song.sections[1].title
# Verse 1

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
