Vim plugin

[bricoletc]

As part of adding editor integration, could make a vim plugin as in black

[ashwinvis]

Perhaps configuring in some popular plugin would do? For example:

• https://github.com/sbdchd/neoformat
• https://github.com/chiel92/vim-autoformat

@ashwinvis there is now a self-contained vim plugin: https://github.com/snakemake/snakefmt/blob/master/docs/editor_integration.md#vim.

However, it could be interesting to add support for vim-autoformat in the future. I guess one option is just writing up a section in the editor_integration document saying i)Set up filetype detection ii)Setup formatters and formatdef for the snakemake file type as per https://github.com/chiel92/vim-autoformat#basic-definitions
Another option would be a PR to vim-autoformat itself, but not sure if can add filetype detection for snakemake files there.

I use neoformat and I realized it is as simple as copying black's definition. The only difference was there is no -q / --quiet flag in snakefmt, but it does not seem to matter. It works:

let g:black_linelength=82
let g:neoformat_snakemake_snakefmt = {
        \ 'exe': 'snakefmt',
        \ 'args': ['-l '.g:black_linelength, '-'],
        \ 'stdin': 1,
        \ }

let g:neoformat_enabled_snakemake = ['snakefmt']

To make it work I run :Neoformat in any open file buffer. If you want to mimic this in your plugin you could:

if exists(":Neoformat")
  command! Snakefmt :Neoformat! snakemake snakefmt
endif

Or contribute it upstream into the neoformat repo.
