1. Open two terminals (or tmux windows, etc.)
2. cd your/project/directory in both of them
3. Run nvim in one of them
4. Run cargo lrun in the other
5. In case of compiling errors nvim opens new or existing tabs with the files on affected lines and columns
6. Fix the error, save the file and nvim will jump to the next error location
7. cargo llrun (cargo llcheck, etc.) will open them in case of warnings as well.

1. Auto-jumps work only if

• current mode is normal
• current buffer is either empty or contains some existing and unmodified (saved) file

This is by design, in order to not disrupt from active text editing or file navigation process.

2. Auto-jump on each file save is currently imprecise

• it may jump to a wrong line if it moved
• it may not jump at all, if the next affected line is supposed to be modified already

For precise jump please rerun cargo ll{check,run,etc.}.

3. Before running nvim: Current Directory should be Project (sub)directory

• that's required so cargo-limit could figure out which exact nvim instance should be controlled
• only first nvim instance with current project (sub)directory will be controlled by cargo-limit.

Open Files in Buffers Instead of Tabs

function! g:CargoLimitOpen(editor_data)
  let l:current_file = resolve(expand('%:p'))
  if l:current_file != '' && !filereadable(l:current_file)
    return
  endif
  for location in reverse(a:editor_data.files)
    let l:path = fnameescape(location.path)
    if mode() == 'n' && &l:modified == 0
      execute 'edit ' . l:path
      call cursor((location.line), (location.column))
    else
      break
    endif
  endfor
endfunction

Populate a QuickFix List

set errorformat =%f:%l:%c:%m

function! g:CargoLimitOpen(editor_data)
  let l:winnr = winnr()

  cgetexpr []
  for file in a:editor_data['files']
    caddexpr file['path'] . ':' . file['line'] . ':' . file['column'] . ':' . file['message']
  endfor

  if empty(a:editor_data['files'])
    cclose
  else
    copen
  endif

  if l:winnr !=# winnr()
    wincmd p
  endif
endfunction

1. Install jq
2. Create open-in-gedit.sh:

#!/bin/bash

jq --raw-output '.files |= unique_by(.path) | .files[] | [
    "gedit",
    .path,
    "+" + (.line | tostring) + ":" + (.column | tostring),
    "&"
] | join(" ")' | bash

3. chmod +x open-in-gedit.sh
4. Set CARGO_EDITOR=/path/to/open-in-gedit.sh environment variable
5. Run cargo lrun in your project directory
6. In case of compiling errors open-in-gedit.sh will open files in gedit on affected lines and columns
7. cargo llrun (cargo llcheck, etc.) will open them in case of warnings as well.
