Previously when diffing two files where one did not have a newline at
the end of the file, gitsigns was unable to stage such differences since
this information was not captured during the diff stage.
If you run `vim.diff('a', 'a\n')` you get the result:
@@ -1 +1 @@
-a
\ No newline at end of file
+a
However if you run `vim.diff('a', 'a\n', {result_type='indices'})` you
get:
{ {1, 1, 1, 1} }
And since Gitsigns tracks changes as a list of text lines, the
information about a missing newline at the end of the file is not
correctly tracked.
The main consequence of this is that staging hunks which contain these
lines would result in an error as the generated patch would not apply
since it was missing "\ No newline at end of file".
To fix this, the internal hunk object now tracks this end of file
information and patches are now generated correctly.
- Added GitSigns*Inline and GitSigns*LnInline to be used with word diff
- GitSigns*LnInline is used for word diff with config.word_diff
- GitSigns*Inline is used for word diff in hunk previews
- Added GitSigns*VirtLn and GitSigns*VirtLnInline to be used with
`config.show_deleted`.
- Define GitSigns highlights conditionally as opposed to only defining
them if certain features are enabled.
