1. Pyflakes errors in your Vim quickfix window

    To use Pyflakes as your “compiler” for Python files in Vim put this into ~/.vim/compilers/pyflakes.vim 1:

    CompilerSet errorformat=%f:%l:\ %m
CompilerSet makeprg=pyflakes

    Then you can do :compiler pyflakes to set the compiler (although you might want to do that in an ftplugin) and :make % to run the current file through Pyflakes and put any errors into your Vim quickfix window.

    1. This assumes that “pyflakes” is an executable in your path that runs Pyflakes, adjust makeprg accordingly. ↩
