• flymakeとpyflakesを連携させて、オンザフライで構文チェックやらをしてくれて、ヤバげなところをハイライトしてくれる
  • 別にpythonだけに限らないけれど、prefixを入力してtab押すと、開いているファイル内のtokenを補完してくれる
  • pythonコードだと、文字コード指定がない場合勝手に先頭に文字コード指定を挿入する
  • あと色とか弄ってる。Emacs.appで幸せになれる
  • anything.elはろくに育ててない


  • pyflakes


  • anything.el
  • auto-complete.el
  • python-mode

emacs 23系
