This commit makes branch.vim use neovim's async jobs instead of a system()
function. This way we avoid the v:shell_error overwrite bug and allow live
updates of the untracked status.
* The head string is now calculated iff it has changed.
* The not exists symbol for current file appears as soon as its status is known.
* Fixes various problems with asynchronous status checking, such as:
* The not exists symbol keeps appearing and disapearing. This happened when
file was marked as not existing, the untracked cache was invalidated, and
the cache update is started, but in the meantime, the head string
calculation used the current (empty) value of the cache.
* The not exists symbol never appears, because cache keeps getting invalidated
before b:airline_head is emptied and updated.
closes#1306
* Introduce a config variable that holds the vcs-dependent parts of code.
* Removes `get_*_untracked` duplication by merging their logic together.
* Removes custom checks for 'git' or 'hg'. Functions now rely on provided config
argument.
* Use loops instead of manually specifying each handled VCS.
closes#1303
This commit fixes a bug, where untracked files in Git repos did not get the not
exists symbol displayed. The fix works by replacing the previous check for
whether currently edited file is a directory or not with a check based on
`findfile`. More detailed explanation follows.
VCS extension to vim-airline checks whether currently edited file is untracked.
The previous `s:get_git_untracked` implementation, which was used for the
aforementioned purpose for Git repos, was buggy, because it did not return the
untracked symbol in most situations, i.e. the edited file is untracked, but it
was treated as if it wasn't.
The root cause was the second clause in boolean expression checking the output
of `git status`:
if output[0:1] is# '??' && output[3:-2] is? a:file
It was added to make sure we are not checking a directory, but at this point in
the program `a:file` is an absolute path, while output of `git status` is a
relative path from the root of git repo. So the `is?` expression failed in most
situations.
These are forks/alternate versions of Solarized, without many of the
dynamic elements or the extensive terminal support.
[flattened](https://github.com/romainl/flattened) is a basic, totally
static version of Solarized with only ansi and GUI support.
[NeoSolarized](https://github.com/iCyMind/NeoSolarized) is a version
focusing on true/24-bit color support and NeoVim support, with limited
dynamic options.
[solarized8](https://github.com/lifepillar/vim-solarized8) is a version
focusing on vim/neovim true color support and limited dynamics. It is
already supported (`match()` matches it), but it is at least worth
noting.
Many users, including myself, use these themes over the original
Solarized for performance or technical reasons. Many users believe they
are incompatible with airline because automatic theming no longer
functions. While they can manually override the theme, most people seem
to miss this option in the documentation and give up.
It would be a nice quality of live improvement if airline detected these
themes and enabled its own Solarized theme automatically to match.
This makes it so if the whitespace symbol (g:airline#extensions#whitespace#symbol) is an empty string, we don't end up wth two characters at the beginning of the message.
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
