commit #3d667c32d3ac04 fixed a bug, that a section was not considered
empty for the statusline, also g:airline_skip_empty was set.
However unfortunately, this lead to a regression, makeing the tabline
ugly, because sections, that contained a single highlighting group would
be considered empty and would therefore be skipped. Since this is not
what is expected, make s:section_is_empty() return zero, when it notices
we are looking at a tabline.
fixes#1273
airline_c (which contains the filename) usually is used together with
the buffer number, so that several windows showing the a different
buffer do not share the same highlighting group.
This was fixed in 73aea86a, but unfortunately it was forgotten to not
only add this to the current group, but also modify the previous group
accordingly. This is what this patch does.
fixes#1268
When cacheing the values of buffer number, window number per tabpage, we
might forget to update the statusline when it is actually needed, e.g.
on `:tab help h | norm! gt` which would then still display "Help" also
we are not in a help window anymore.
Therefore cache those values (including current tabpage number)
globally.
fixes#1253
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
Using let g:airline_section_y = airline#section#create_right(['ffenc','%{strftime("%H:%M")}'])
will result in an output string of `utf-8[unix] < < 00:00`
This happens, because the function util#prepend() will eventually add an
extra separator, if the width is zero. Therefore, when building the
string, remember, if the last section added an extra separator and only
add one, if there hasn't been added one before.
fixes#1220
The syntastic plugin recommends to adjust the statusline.
This does not apply for vim-airline for obvious reasons. Therefore
mention that this recommendation does not apply for us.
Cache the hunk values. In case of short windows, shorten the hunk string
a little bit and make the branch extension take the hunk value into
account when deciding how much to shorten it.
Sometimes, if a buffer triggers many whitespace check warnings,
and the Vim window size is too small, other parts of the statusline
might become unreadable.
Therefore, if the window size is smaller than say 120 characters
and the whitespace warning > 9 chars, limit it to 10 characters
and inidicate, that there is more to come
fixes#1187 by making sure, we only call functions, that actually exist.
Should make vim-airline work with lady loaded YCM, e.g. using vim-plug:
```viml
" Code to execute when the plugin is loaded on demand
Plug 'Valloric/YouCompleteMe', { 'for': 'cpp' }
autocmd! User YouCompleteMe if !has('vim_starting') | call youcompleteme#Enable() | endif
```
Make sure, b:airline_head variable is set, also it is initially set in
this function earlier. But see #1171 for an error.
Therefore, before checking if the variable is empty, make sure it
exists.
fixes#1171
This is a little bit a hack, because by the time the separators are
added, it is not clear, if the following section is empty, therefore
we need to parse the content of the following section and eval the
expressions to find out, if this is empty
Remarks:
- catch all exceptions when eval'ing statusline
- make sure, that the seperators are highlighted
even when skipping empty regions (highlight group
names need to be adjusted)
- if a section is defined as empty, it will be removed completly from
the statusline. This means, it won't be called on the next update
and may not refresh properly (e.g. when the whitespace check
triggers, therefore, the whitesapce extension has to call an
explicit redraw whenever it is supposed to be refreshed)
airline#extensions#load() tries to load all extensions,
the user has specified in g:airline_extensions.
However, if e.g. bufferline is requested to be loaded, but
is not installed, it will throw an error
E117: Unknown function: airline#extensions#bufferline#init
Therefore, catch E117 and show a warning.
closes#1127
