In this context older vims are those without timer_start() and lambda.
The plugin always used to process the buffer at startup. Then in #734
an optimisation was introduced to defer processing at startup, to keep
vim's startup fast. However in this optimisation older vim's
unintentionally lost their startup processing altogether.
If the user has removed the "gitgutter CursorHold" autocommand, which
is the documented way to turn off automatic refreshing, calling the
autocommand at start up will fail. Use a timer instead.
This implementation also changes the processing delay to 1ms instead of
'updatetime'.
See #840.
E.g., passing an empty group name to the sign argument linehl (e.g.,
"linehl=") causes the following error:
```
Error detected while processing /usr/home/0mp/.vim/plugged/vim-gitgutter/plugin/gitgutter.vim[96]..function gitgutter#highlight#define_signs[10]..<SNR>56_define_sign_line_highlights:
line 9:
E1249: Group name missing for linehl
```
This patch makes the those errors go away by passing "None" when no
group name is needed.
This only applies to floating preview windows on Neovim.
Handles the following way of closing the floating preview:
- <Esc>
- Moving cursor
- 2<C-W>c (where 2 is the floating window's window number)
- <C-W><C-W> to move into and out of the floating window
Closes#786.
This bug was introduced by 9784226 in #708. It had the effect of not
allowing an existing hunk preview window to increase in size for a
larger hunk (up to 'previewheight').
See #775.
I would prefer to remove the statusline altogether in the hunk preview
window, making it consistent with the floating preview window. However
I do not think that is possible; the best one can do is make it blank.
In da77e46310 the function changed to be
consistent with GitGutterGetHunks(), i.e. to show "no data" if called in
a buffer for which gitgutter is inactive.
This function is mostly used in status lines. GitGutter is inactive
when a popup window is open. The commit mentioned above meant that when
a completion window was open, the hunk summary in the status line
changed to show no data. It changed back again once the completion
window was closed, but the overall effect was a little distracting.
This commit reverts the change.
Closes#771.
