If GitGutter* highlight groups already exist, they were declared
deliberately (either by the colorscheme maintainer or the user). So do
not adjust them.
However if you would like to make the signs' backgrounds match the sign
column, you can do this:
let g:gitgutter_set_sign_backgrounds = 1
This was introduced in 07d7c9d4 because many colorschemes at the time
had ugly sign columns, and people kept asking how to deal with it.
These days there are many more plugins which use the sign column and
consequently more colorschemes pay attention to the SignColumn highlight
group.
Therefore it no longer makes sense for vim-gitgutter to adjust the
sign column's appearance.
To restore the previous behaviour, add this to your vimrc:
highlight! link SignColumn LineNr
See #696.
Previously if the user or the colourscheme had already defined
GitGutter* highlight groups, the plugin would leave their backgrounds
alone. This pushed the responsibility for figuring out and specifying
the correct backgrounds onto the user or colourscheme maintainer.
With this change the plugin now sets the correct background on existing
GitGutter* highlight groups.
Also, the documentation was simplified so it is clearer how to set your
own colours for the signs.
When you look at previous versions of a file, e.g. with Fugitive's
:0Gclog, gitgutter will set the diff base to the current version's
parent so that diff markers appear as expected.
Thannks to @rcreasi for the idea and initial implementation.
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.
This change makes the plugin default to using the highlight groups
defined by the colorscheme instead of hardcoding its own foreground
colours.
If you liked the previous colours you can restore them by adding these
lines to your vimrc:
highlight GitGutterAdd guifg=#009900 guibg=<X> ctermfg=2 ctermb=<Y>
highlight GitGutterChange guifg=#bbbb00 guibg=<X> ctermfg=3 ctermb=<Y>
highlight GitGutterDelete guifg=#ff2222 guibg=<X> ctermfg=1 ctermb=<Y>
– where you should replace <X> and <Y> are the background colour of your
SignColumn in the gui and the terminal respectively.
For example, with the solarized colorscheme and a dark background,
guibg=#073642 and ctermbg=0.
Closes#545, #560.
