GitGutterLineHighlightsToggle doesn't update immediately on neovim about vim-gitgutter

[airblade]

Is this toggling from off to on or on to off or both?

Here's the implementation:

vim-gitgutter/autoload/gitgutter/highlight.vim

Lines 1 to 31 in 67ef116

	function! gitgutter#highlight#line_disable() abort
	let g:gitgutter_highlight_lines = 0
	call s:define_sign_line_highlights()
	if !g:gitgutter_signs
	call gitgutter#sign#clear_signs(bufnr(''))
	endif
	redraw!
	endfunction
	function! gitgutter#highlight#line_enable() abort
	let old_highlight_lines = g:gitgutter_highlight_lines
	let g:gitgutter_highlight_lines = 1
	call s:define_sign_line_highlights()
	if !old_highlight_lines && !g:gitgutter_signs
	call gitgutter#all(1)
	endif
	redraw!
	endfunction
	function! gitgutter#highlight#line_toggle() abort
	if g:gitgutter_highlight_lines
	call gitgutter#highlight#line_disable()
	else
	call gitgutter#highlight#line_enable()
	endif
	endfunction

It depends on whether g:gitgutter_signs (whether to show signs) is on or off.

Both. Judging by the code, I guess sign define changes are not applied to already placed signs, until they are removed and placed again, so it's a neovim bug.

That sounds plausible to me.

I expect that writing a separate code path using extmarks would resolve this, but I don't really have time to do that at the moment.

Defining your own command which calls :GitGutterLineHighlightsToggle and then :GitGutter, i.e. your workaround, seems like the best way past this for now.
