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.

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.
