This removes the g:gitgutter_sign_column_always option.
Vim 7.4.2201 introduced the |signcolumn| option to configure when the
signcolumn is visible, building in behaviour which the plugin provided
manually.
Although it would be good to maintain this feature for older Vims, the
complexity added by the code outweighs the benefit of backward
compatibility.
On FocusGained the current tab is force-updated. If there are any other
tabs, we want to make sure they are also force-updated when the user
next switches to them. To do this we set a flag which is read and
cleared on TabEnter.
See #525.
This was prevented to avoid an infinite loop on gVim (see #42).
However that was 5 years ago and this no longer seems to be a problem
(even running synchronously).
- Hunk stage/undo/preview no longer saves the buffer.
- Hunk undo no longer makes locations go out of sync.
- Grep can be opted out of (grep output with ansi escapes is number one cause
of issues).
- Replaced g:gitgutter_grep_command with g:gitgutter_grep.
- Always runs git-diff the same way instead of in two possible ways.
- Separated detection of git tracking from diffing.
- Simplified path handling.
- Removed support for xolox shell: Windows taskbar does not flash with async
jobs.
- Removed g:gitgutter_{eager,realtime}.
- Simplified implementation generally.
When opening vim with multiple files, e.g. via `vim -o file1 file2`, Vim
fires a `BufEnter` event for each file. However the effective buffer
number (`<abuf>`) is always 1, instead of being each buffer's number in
turn, so we end up processing the first buffer n times instead of each
of n buffers once.
This commit is a brute force workaround to ensure all buffers are
processed if there is more than one.
Closes#428.
Before this change the TabEnter/BufEnter logic was intertwined with
the logic for BufWritePost,FileChangedShellPost.
Separating the concerns fixes a minor bug where a TabEnter-BufEnter
combination led to the plugin not updating the diff the first time the
buffer was written.
