rakっていうコマンド便利ですよ
問題
% rak invalid zsh: command not found: rak % which gem gem not found % which ruby ruby not found %
Σ(ﾟдﾟlll)ﾌｧ!?
Rubyから入れましょう
1) rvmでRuby2.0.0を入れる
% cat /etc/debian_version
7.5
% curl -sSL https://get.rvm.io | bash -s stable --ruby=2.0.0 Downloading https://github.com/wayneeseguin/rvm/archive/stable.tar.gz Installing RVM to /home/otiai10/.rvm/ Adding rvm PATH line to /home/otiai10/.profile /home/otiai10/.bashrc /home/otiai10/.zshrc. Adding rvm loading line to /home/otiai10/.bash_profile /home/otiai10/.zlogin. Installation of RVM in /home/otiai10/.rvm/ is almost complete: * To start using RVM you need to run `source /home/otiai10/.rvm/scripts/rvm` in all your open shell windows, in rare cases you need to reopen all shell windows. # otiai10, # # Thank you for using RVM! # We sincerely hope that RVM helps to make your life easier and more enjoyable!!! # # ~Wayne, Michal & team.

とあるのでまあその通りに
% which ruby ruby not found % source /home/otiai10/.rvm/scripts/rvm [反応無し] % which ruby /home/otiai10/.rvm/rubies/ruby-2.0.0-p481/bin/ruby
ちなみに
% which gem gem () { typeset result ( typeset rvmrc rvm_rvmrc_files=("/etc/rvmrc" "$HOME/.rvmrc") if [[ -n "${rvm_prefix:-}" ]] && ! [[ "$HOME/.rvmrc" -ef "${rvm_prefix}/.rvmrc" ]] then rvm_rvmrc_files+=("${rvm_prefix}/.rvmrc") fi for rvmrc in "${rvm_rvmrc_files[@]}" do [[ -s "${rvmrc}" ]] && source "${rvmrc}" || true done unset rvm_rvmrc_files command gem "$@" ) || result=$? hash -r return ${result:-0} } %
gemもある。
2) gemを使ってrakを入れる
とりあえずruby2.0.0環境だけでいいでしょう
% gem install rak Fetching: rak-1.4.gem (100%) Successfully installed rak-1.4 Parsing documentation for rak-1.4 Installing ri documentation for rak-1.4 1 gem installed % which rak /home/otiai10/.rvm/gems/ruby-2.0.0-p481/bin/rak
入った
3) rak使ってみる
rakはgrepよりラク。
- 勝手に色づけ
- デフォルトでカレントディレクトリからrecursiveに検索
- など？
こういう感じ
4) rakで検索できるファイル拡張子を追加
Ruby2.0.0下で入れたgemはここ~/.rvm/gems/ruby-2.0.0-p481/gems/にあるので、
% cp ~/.rvm/gems/ruby-2.0.0-p481/gems/rak-1.4/bin/rak ~/.rvm/gems/ruby-2.0.0-p481/gems/rak-1.4/bin/rak.backup % vi ~/.rvm/gems/ruby-2.0.0-p481/gems/rak-1.4/bin/rak
diff -u ~/.rvm/gems/ruby-2.0.0-p481/gems/rak-1.4/bin/rak.backup ~/.rvm/gems/ruby-2.0.0-p481/gems/rak-1.4/bin/rak

こうしとくと、
こうなります。ちゃんと.goなファイルも検索できてる。
ラクです。
