RubyでGithubに公開されているOSSのバージョン間差分を表示する

Last updated at Posted at 2013-05-16

この記事は最終更新から1年以上経過しています。 気をつけてね。

最近はOpen-source software (OSS) に頼りきりなので、更新があった時に差分をチェックしたい。

Grit(RubyGems)で簡単に取れそうなのでやってみた。

対象のOSSProjectを選ぶ

Gritはリモートのリポジトリにを直接見ることが出来なさそうなので、一旦サンプルのOSSProjectをローカルにコピーした。

今回のチョイスは近所のよしみで**concrete5**です。

タグを取る

./concrete5 ディレクトリにクローンしたものとします。
#tagですべてのタグがGrit::Tagオブジェクトに突っ込まれました。

rubycode
require 'grit'
                                                                                                                                                                               
repo = Grit::Repo.new('concrete5')
repo.tags.map {|t| puts t.name}

=>
5.6.1.2
5.6.1.1
5.6.1
5.6.0.2
5.6.0.1
5.6.0
5.5.2.1
5.5.2
5.5.1
5.5.0
5.4.2.2
5.4.2.1
5.4.2

5.6.1.2と5.6.1.1の差分が気になる体で行きましょう。

コミット一覧

#commitsではGrit::Commitオブジェクトがとれました、新しい順ですね。

rubycode
repo.commits('5.6.1.2')

=> [#<Grit::Commit "b5b03cfdeed7cb512ea75403574599553472102a">,
 #<Grit::Commit "5b0e2774e8991d236657908208e7be55962697d3">,

 #<Grit::Commit "3f1aa9dadf12966c52a083c69e128c7fe97c0b79">]

デフォルトは最新10件です。

diffを取る

比較するGrit::Commitのオブジェクトを#diffにかけると、ファイルごとの差分であるGrit::Diffオブジェクトが取得できました。

rubycode
new_commit = repo.commits('5.6.1.2')
old_commit = repo.commits('5.6.1.1')

repo.diff(new_commit[0], old_commit[0])

=> [#<Grit::Diff:0x00000002b67248

@a_path,@b_path,@new_file,@deleted_file,@ renamed_file あたりが気になりますね。

ざっと一覧で見れるように表示します。

rubycode

ファイル構成には変更が無いみたい。

Diff付きで表示する

差分情報はGrit::Diffオブジェクトの@diffに入っています。
Syntaxhighlightの関係で全部putsにしたり、出力を一部加工しています。

追記：このサンプル、NewとOldが逆です。

rubycode
diffs.map do |d|
  puts '## ' + d.a_path
  puts '### ' + d.b_path
  puts '**New File!**' if d.new_file
  puts '**Deleted!**' if d.deleted_file
  puts '**Renamed!!**' if d.renamed_file
  puts "### Diff"
  puts '```'
  puts d.diff unless d.deleted_file
  puts '```'
  puts '----'
end

MarkDownにする

引数を取れるようにしてMarkDown形式にして表示するサンプルスクリプトを用意しました。
puts の嵐ですいません。

追記：qiita用にdiffのシンタックスハイライト入れた。
追記：diffがnilだったらコケたので修正
追記：NewとOldが逆だったので直した。

sample.rb
require 'grit'

repo = Grit::Repo.new(ARGV[0])

old_commit = repo.commits(ARGV[1])
new_commit = repo.commits(ARGV[2])

diffs = repo.diff(old_commit[0], new_commit[0])

これをTumblrにメールで投稿しようとしたがうまく表示されなかったのでここに貼ってしまおう。

実行はこの様に、ディレクトリとタグなりブランチ(origin/branch_nameで渡す)なり、sha1をパスすればOK.

$ ruby ./sample.rb concrete5 5.6.1.1 5.6.1.2

herokuあたりで適当に自動実行させておきたいですね。

以下出力
