On a .python file, I see the following for :ALEInfo
:ALEInfo
Current Filetype: python
Available Linters: ['flake8', 'mypy', 'prospector', 'pycodestyle', 'pydocstyle', 'pyflakes', 'pylint', 'pyls', 'pyre', 'vulture']
Enabled Linters: ['flake8', 'mypy', 'pylint']
Why is pycodestyle not enabled? Is there a way I can automatically enable it for all python files? I have pycodestyle already installed with pip, from the command line I can do pycodestyle . and it works.
I just found out that only flake8, mypy and pylint are enabled by default. I was trying to find out before but couldn't until someone pointed to
https://github.com/w0rp/ale/blob/master/doc/ale.txt#L1438
or :help ale_linters
In order to enable new linters, I need to set:
let g:ale_linters = {'python': ['pycodestyle']}
The doc above has this part:
The |g:ale_linters| option sets a |Dictionary| mapping a filetype to a
|List| of linter programs to be run when checking particular filetypes.
This |Dictionary| will be merged with a default dictionary containing the
following values: >
{
\ 'csh': ['shell'],
\ 'elixir': ['credo', 'dialyxir', 'dogma', 'elixir-ls'],
\ 'go': ['gofmt', 'golint', 'go vet'],
\ 'hack': ['hack'],
\ 'help': [],
\ 'perl': ['perlcritic'],
\ 'perl6': [],
\ 'python': ['flake8', 'mypy', 'pylint'],
\ 'rust': ['cargo'],
\ 'spec': [],
\ 'text': [],
\ 'vue': ['eslint', 'vls'],
\ 'zsh': ['shell'],
\}
One thing you should be aware of: flake8 invokes pycodestyle and pyflakes. So configuring ale to run flake8 and either of those two will lead to duplicate warnings:
