When using vim-gitgutter and fugitive:
The hunks extension and the branch extension work as expected when the
file is first loaded; both parts are added to the statusline.
Once the cursor is moved and stopped for &updatetime ms:
1. The branch extension clears b:airline_head on CursorHold
2. Somehow (?) airline#statusline gets called on CursorHold
3. The hunks extension returns '' when b:airline_head is empty, causing
the hunks to be removed from the statusline.
It doesn't make sense to clear airline_head just because the cursor
moved, and the commit message adding the line doesn't say why:
13297cee03
Commit 174b7e1962 relies on airline_head
being set.

Currently, vim-airline will check untracked status for files e.g. living
in .git. So when editing .git/config it will show as being untracked.
While technically, this is correct I prefer not to see this for those
files. So skip the check for those files.
If a file is edited inside a git repository, which lies within a git
repository, the branch extensions shows 'gitmaster | hgdefault'
To make it more obvious, that we are looking into both repositories
here, use 'git:master | hg:default'
closes#1482
Currently vim-airline assumes, that the git_dir is part of the path for
the file being edited. This has changed, since git supports worktrees.
So take care of b:git_dir (which is set by fugitive) being a path
differently from the absolute path of the file being edited (however, it
should include the substring worktree in that case).
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.
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.
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
"system()" called by "get_git_untracked" and "get_hg_untracked" fails
sometimes. It reports error "Can't open file /tmp/***".
The root cause is that the file path for system() contains some unordinary
character and lacks quotes.
first argument of git status is <pathspec> in git speech,
and so if you feed it a directory, that contained an untracked file,
the directory would be marked as untracked. So fix this.
This will show a little not-existing sign in a buffer,
if that file lives in a git/hg repository but does not exists
there yet. Use `:let g:airline_symbols.notexists='!'` to configure
the '!' as symbol. By default, will use U+2204 symbol
To not impact performance by shelling out a lot, the result is cached
until the buffer is written or a shell command is issued.
Should work with mercurial and git.
fixes#925
meaning that branches retrieved from those are now displayed side by
side. The order can be customised with g:airline#extensions#branch#vcs_priority.
The VCS name is now prepended to the branch name to be able to tell
which is which. The VSCCommand behaviour is unchanged.
Also restructured the code a little bit, and made found_fugitive_head
variable behave as its name suggests.
- Fugitive can edit virtual files that represent objects in git; while
editing these files, it still reports on the HEAD of the relevant
repo, which should be displayed as the branch (rather than having the
branch section disappear)
If the user updates the airline_symbols.branch variable later in the vimrc, the value will not update after the initial init. Since these variables are only used in the get_head() function, I moved them locally within the function to allow evaluation on each instance.
