This vim binding will make <C-l> correct the previous spelling mistake:

inoremap <C-l> <c-g>u<Esc>[s1z=`]a<c-g>u

How do I modify it to make it correct the previous mistake on the current line only?

inoremap <C-l> <c-g>u<Esc>:call <sid>fixLineSpellError()<cr>`]a<c-g>u

function! s:fixLineSpellError()
  " get current line number
  let lnum = line('.')
  " find last misspelled word before cursor
  normal! [s
  " do nothing if line changed
  if lnum != line('.') | return | endif
  " fix spell error if line doesn't change
  normal! 1z=
endfunction

Map break down:

  • <c-g>u<Esc> break undo sequence, switch to normal mode.
  • :call <sid>fixLineSpellError()<cr> call a script scope function to fix current line spell error.
  • `]a move cursor back to the end of last change, start to append.
  • <c-g>u break undo sequence.
  • Works as intended and well explained, thanks! – Kevin Liu Apr 30 at 13:55
