airline#system#util for nvim used to fall back to 'system' implementation on
command error. This behavior caused conflict with other plugins if 'util' was
executed with a failing command as part of a ShellCmdPost event.
This commit makes 'util' interpret command error as persistent and not call
'system' in such a case.
This commit fixes#1317.
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.
