On Vims that support it, signs are placed in the "gitgutter" group with
a priority set by g:gitgutter_sign_priority.
Closes#544.
Closes#576.
Closes#627.
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.
In fe2b4ec869 (from 2013) the plugin
started using a dummy sign to prevent the sign column briefly
disappearing then reappearing when updating signs.
Since then Vim has vastly improved its handling of signs and the sign
column no longer flickers like this.
The development versions of v0.3.2 also report `has('nvim-0.3.2')` to be
true even if they do not support the `numhl` feature. So here it catches
and ignores the possible errors.
An asynchronous job at startup evidently triggers a Vim (not NeoVim)
rendering bug in some terminals and/or with certain colorschemes.
Terminals reported to be affected: libvte-based ones such as
gnome-terminal, xfce4-terminal, lxterminal, kitty.
Terminals reported to be unaffected: xterm, urxvt.
Closes#619.
For default sign colours.
It seems the Diff* highlight groups are generally designed for line
highlighting so they have background colours which differ from the main
background colour. While desirable for line highlights, this isn't what
we want for the signs.
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.
