If a file is subject to a clean/smudge filter, it is impossible to stage
an individual hunk. Therefore if the user tries to stage a hunk, ask
whether they want to stage the entire instead.
Determining whether a clean/smudge filter applies is done with:
git check-attr filter -- path/to/file
– and looking for "unspecified" (not to be) in the output. The result
is cached so that for a file which is not filtered (the common case),
staging multiple hunks only incurs the cost of the external call once.
See #796.
This tells git-show to output the smudged version of a file if a
clean/smudge filter is defined for it. In turns this allows us to diff
the buffer contents (which is smudged) against the reference version.
However patches cannot be applied.
See the man pages for git-show and gitattributes for more information.
See #796, #435.
If g:gitgutter_diff_base has been set and the file being processed does
not exist in that branch/commit, ensure that every line is marked as
added - this is how git-diff behaves.
Fixes#855.
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.
