consider a window with these splits:
,----
| file1
| ---
| file2
| ---
| file1
`----
If the top buffer is the active one and you start modifying this buffer,
this will also reset the highlighting for the inactive buffer2, since
the highlighting group 'airline_c_inactive' is used for both windows
(one having the unmodified buffer 'file2' and one having the modified
'file1').
This lead to the incorrect highlighting of the buffer name of file2.
Airline basically already created different airline_c<bufnr>_inactive
highlighting groups, but unfortunately did not use them.
Therefore, make the builder aware of this and always append the buffer
number to the group 'airline_c' if it is in an inactive window.
2) we need to make sure, the highlighting won't get overwritten, so
make the highlighter aware of this situation as well, by appending the
buffer number to the group name, if it creates the 'inactive' mode
groups and a buffer number has been given.
this fixes#1233
If active buffer is modified, `:AirlineRefresh` apply `normal` highlight
instead of `normal_modified` highlight.
No particular config is requiered to reproduce this bug.
I see this bug with option `g:airline_skip_empty_sections` set.
Add any modification at the active buffer return to normal mode,
**do not save** and wait a few seconds, you can see highlight change to
normal but file is modified.
Without option `g:airline_skip_empty_sections`, add any modification at
the active buffer return to normal mode and type `:AirlineRefresh` you
can see change to bad highlight .
This is required when used with 'Normal' with a transparent background.
Falling back to 1 here results in "red" for "ctermbg"!
I think it's important to keep the 'NONE' color property here, instead
of hardcoding the fallbacks (even if white would be used instead of
red).
Most of them seem to be caused by using :hi statements, although the
highlighting group to be created is exactly the same. Therefore, get the
info from actual definition and only execute :hi when the new group is
actually different.
Also try to avoid to generate :hi statements when the popupmen is
visible. This causes flickers.
this issue fixes#758
The problem was, that a given color list ['','',0,'',''] was given to
the airline#highlighter#exec() function. This resulted in the following
comparison:
if (get(colors,2,'') != '') ? 'ctermfg='.colors[2] : ''
which, since echo 0 != '' returns falls will return a single:
:hi group
and no color codes given and therefore, Vim would output the
current highlighting group.
Use isnot# as comparison to fix this issue.
