来週16日(火) 15時からSFCデルタ棟S112でRuby初心者向け勉強会をやる予定があるので（だれでもどうぞご自由にいらしてください）
Rubyの基本的な構文のほかに、どんなgemを普段使っているんだっけと思って調べている。
ワンライナーで集計
Gemfile内に書かれたgem名を数えるワンライナー。GemfileについてはRuby書くならBundler使えで解説した。
find $HOME -name Gemfile | grep "^$HOME/.*Gemfile$" | xargs grep "^gem " | ruby -lane 'puts $_.scan(%r{["'\\\'']([^"'\\\'']+)["'\\\'']})[0]' | sort | uniq -c | sort -nr
.rbと.ruファイル内のrequireを数えるワンライナー。
find $HOME -name "*.r[bu]" | grep "^$HOME/.*\.r[bu]$" | xargs grep "^ *require " | ruby -lane 'puts $_.scan(%r{["'\\\'']([^"'\\\'']+)["'\\\'']})[0]' | sort | uniq -c | sort -nr
集計結果
最近使い始めたMacbook Air内のGemfileに書かれたgemを数えた。Gemfileに書いているもの == 明示的に俺が自分で「このgemを使う」と思って書いている物。
jsonはすごい。
手元で開発しているアプリの他に、CUIツールで使うようなgemも多い。args_parserとかrainbowとかmarkdown系とか。

ホームディレクトリ内の.rb/.ruファイル内のrequireを数えた。多すぎるので上位300件だけコピペ。
こちらはホームディレクトリにインストールしているrbenv内のgemがrequireしたものも含まれている。
自分がrequireしているgem以外にもGemfileと違ってbackports、strigio、rbconfigやテスト関係などアプリよりgem内で使われる事が多く見える。
