Rubyで遊ぶよ

Mac OS X 用、open コマンドの zsh 補完関数

11:33

を作るための ruby スクリプト。アプリケーションフォルダの中身をスキャンして補完関数に埋め込む方針。

その前に2つ準備がいる。

その1。$HOME/.zsh/functions というディレクトリを作成しておく。

その2。zshrc に、

fpath=(~/.zsh/functions ${fpath})
autoload -U compinit
compinit

と書く。(もし autoload -U compinit が既に書かれてる場合は、fpath をそれより上で指定しないとだめ)

準備ができたら、以下のスクリプトを実行する。

#!/usr/bin/ruby

home = ENV['HOME']

$apps = []
def find_apps (dir)
  return unless File.directory?(dir)
  Dir.foreach(dir) do |file|
    if file != '.' && file != '..' && File.directory?(File.join(dir,file))
      if file =~ /^(.*)\.app$/
        $apps.push($1)
      else
        find_apps(File.join(dir,file))
      end
    end
  end
end

['/Applications','/Developer/Applications',"#{home}/Applications"].each do |dir|
  find_apps (dir)
end

filename = "#{home}/.zsh/functions/_open"

str = <<END
#compdef open

_arguments \\
  '-a[open with specified application]:application name:( \\
#{$apps.map{|app| "\"#{File.basename(app)}\""}.join(' ')} \\
)' \\
'-e[open with TexEdit]' \\
'*:files:_files'
END

open(filename, 'w') do |f|
  f.print str
end

そうすると、$HOME/.zsh/functions/_open として以下のようなファイルができる。(うちの場合)

#compdef open

_arguments \
  '-a[open with specified application]:application name:( \

)' \
'-e[open with TexEdit]' \
'*:files:_files'

次に zsh を起動したら補完がきいてるはず。

open のオプションは -a と -e 以外にもいくつかあるけど、それらは考慮してない。あしからず。
