Async isort plugin for Vim + Neovim

A lighter, pure-Vimscript version of fisadev's wonderful vim-isort plugin. Mostly written to solve performance + virtual environment issues.

Equivalent to:

command! -range=% Isort :<line1>,<line2>! isort -

...but significantly faster & without the annoying cursor jump.

Designed to run asynchronously in Vim 8 + Neovim, but also backward-compatible with older versions of Vim.

Installation

• Install isort via pip:

  pip install isort

• Install isort.vim via your favorite plugin manager, eg vim-plug:

  Plug 'brentyi/isort.vim'

Usage

:Isort will sort all imports of a file in normal mode, or a range of lines in visual mode.

Mappings are left to the user. Here's what I use:

augroup IsortMappings
    autocmd!
    autocmd FileType python nnoremap <buffer> <Leader>si :Isort<CR>
    autocmd FileType python vnoremap <buffer> <Leader>si :Isort<CR>
augroup END

We can also add a callback function via the isort#Isort(startline, endline, callback) function. For example, we can use vim-codefmt to format after sorting:

call isort#Isort(1, line('$'), function('codefmt#FormatBuffer'))

Configuration

You can configure isort's arguments:

let g:isort_vim_options = '-l 120 --wl 100 -m 2 --case-sensitive'
