The general idea here is to add support for multiple doc styles and I definitely agree! This was something I had on my own todo list as well to implement, but it was optionally for me personally. I'll work on a multi-doc implementation per language ;)

Thanks for your input.

Multiple doc standard are supported, tested and successfully merged into the master branch 🎉

You can overwrite the python doc standard by doing this in your vimrc:

let g:doge_doc_standard_python = 'numpy'
