Python Adventures

Recently I started to use neovim (here is my story). I mainly edit Python codes so I looked around and collected some useful plugins (here is my init.vim file). One of these plugins is neomake, an asynchronous :make using Neovim’s job-control functionality (it also works in ordinary vim, but without the asynchronous benefits).

I had a little contribution to neomake and that’s what I want to write about in this post. I sent a pull request to include vulture as a Python maker. Vulture finds unused classes, functions and variables in your code. Let’s see two screenshots without and with vulture:

Without vulture:

With vulture:

init.vim settings
Here is my corresponding settings that enables vulture too:

Plug 'neomake/neomake'
" {{{
    " neomake is async => it doesn't block the editor
    " It's a syntastic alternative. Syntastic was slow for me on python files.
    " $ sudo pip2/pip3 install flake8 -U
    " $ sudo pip2/pip3 install vulture -U
    let g:neomake_python_enabled_makers = ['flake8', 'pep8', 'vulture']
    " let g:neomake_python_enabled_makers = ['flake8', 'pep8']
    " E501 is line length of 80 characters
    let g:neomake_python_flake8_maker = { 'args': ['--ignore=E115,E266,E501'], }
    let g:neomake_python_pep8_maker = { 'args': ['--max-line-length=100', '--ignore=E115,E266'], }

    " run neomake on the current file on every write:
    autocmd! BufWritePost * Neomake
" }}}
