A tool to manipulate osu! beatmap and local scores database.

Installation

Add this line to your application's Gemfile:

gem 'osu-db'

And then execute:

Or install it yourself as:

$ gem install osu-db

Usage

Load datebase

require 'osu-db'

beatmapdb = Osu::DB::BeatmapDB.new
beatmapdb.load(IO.read('osu!.db'))

scoredb = Osu::DB::ScoreDB.new
scoredb.load(IO.read('scores.db'))

Let's have fun with touhou music

beatmapdb.select{|i| i.source =~ /touhou/i}.shuffle.each do |i|
  puts "#{i.artist_unicode || i.artist} - #{i.title_unicode || i.title}"
  `mplayer "#{i.audio_path}" 2>&1 >/dev/null`
end

Calculate the average accuracy

scores = scoredb.select{|i| i.game_mode == :osu!}
p scores.inject(0){|i, j| i + j.accuracy} / scores.size

Print all taiko scores

beatmaps = beatmapdb.select{|i| i.mode == :Taiko}.map(&:beatmapcode)
scores = scoredb.select{|i| beatmaps.include? i.beatmapcode}
scores.sort{|i, j| i.datetime <=> j.datetime}.each do |i|
  puts "%10s %7d %3d  %s" % [i.user, i.score, i.combo, i.mods]
end
