Use flake8 for Cython with w0rp/ale

Question

I'm using flake8 to check my code with ale plugin. I found a way to make it work with Python 3, but it seems it does not recognize Cython file (.pyx) even if we set as follows.

let g:ale_linters = {
\   'cython': ['flake8']
\}

I also tried

let g:ale_command_wrapper = "source activate py36; %* --filetype=*.py,*.pyx "

Is there any way to set it?

Answer 1

I have never worked on cython, so really don't know if it has a different syntax or something. If the syntax is the same as python, it should be as easy as telling vim to interpret the cython file as a normal python file:

:set filetype=python

Also, instead of setting the filetype on each file, you can define an autocommand in your vimrc as follows:

autocommand BufEnter *.pyx setlocal filetype=python
