GuitarProParser

It is a gem for Ruby that allows to read Guitar Pro files. Now it supports Guitar Pro 4 and 5 files. Version 3 should work but is not tested at all.

Installation

Add this line to your application's Gemfile:

gem 'guitar_pro_parser'

And then execute:

$ bundle

Or install it yourself as:

$ gem install guitar_pro_parser

Usage

Read the file:

song = GuitarProParser.read_file('path_to_file')

Now you can access song's properties like that:

# Get some attributes of the song
puts song.title
puts song.artist
puts song.bpm

# Or read notes
song.tracks.each do |track|
  track.bars.each do |bar|
    puts "There are #{bar.voices[:lead].count} beats in lead voice"
    puts "There are #{bar.voices[:bass].count} beats in bass voice" unless bar.voices[:bass].nil?

    bar.voice[:lead] do |beat|
      beat.strings.each do |string, note|
        puts "Play #{string} string on the #{note.fret} fret."
        puts "Note's duration is #{note.duration}"
      end
    end
  end
end

If you don't need any information about beats, notes and other music stuff you can read headers only:

song = GuitarProParser.read_headers('path_to_file')

# You'll have title, subtitle, artist, etc.
song.title # => 'Title'

# But no notes
song.tracks.first.bars # => []

All available methods and attributes could be found in the source code. :)

You can also export song object to JSON format:

puts song.to_json
# {"meta":{"version":4.0,"title":"Song Title","subtitle":"","artist":"The Artist","album":"The Album" ...
