Only show the "airline theme not found" warning message, when the user
actually used `:AirlineTheme foobar`, not when called by an autocommand
that tries to switch themes when the Vim colorscheme changed.
fixes#1824
While this adds a bit more code it makes it possible to distinguish
between themes not found and errors in themes.
Use :verbose AirlineTheme <foobar>
to also see the error message in case of errors.
Groupnames like 'airline_c1_to_airline_x_inactive' still have to be
processed, so do not skip them.
Also for the tabline, '_inactive' groups are not used, so skip them
Replace by a function that retuns the to be executed highlighting string
Should in theory be a bit faster, since the same function does not have
to be called 5 times per highlighting group.
It probably is not much better, but here are some random numbers:
Profiling:
Previously:
count total (s) self (s)
199 0.022973 0.009909 let cmd = printf('hi %s %s %s %s %s %s %s %s', a:group, s:Get(colors, 0, 'guifg=')…
New:
count total (s) self (s)
79 0.010166 0.000862 let cmd = printf('hi %s%s', a:group, s:GetHiCmd(colors))
Make sure, to also check, if the separator groups have already been
defined. Once they are defined initially, they are usually available in
the palette group. So do not redefine them once they have been created
initially.
references #1779
Previously, we only checked for if the name starts with 'airline_c'
But there could as well be highlighting groups starting being called
'airline_b_to_airline_c5', but if buffer 5 is no longer visible in the
current viewport, then we do not need to recreate those groups.
currently, if the matchstr() evaluates to '', it would skip the required
section, because bnr would be evaluated to zero and since there is no
buffer zero, skip that highlighting group.
Make sure, to only skip the highlighting group if the buffer number is
actually > 0
In a long editing session, there could happen to accumulate several
highlighting groups for buffers that might no longer be visible.
Therefore, only re-create the highlighting group for buffers that are
actually displayed in the current tabpage. If not, skip them.
references #1779
previously, it could happen that the same highlighting group was defined
several times, because it was available in several modes within
g:airline#theme[mode]. So the second one would always win.
Therefore, loop through all modes in reverse order and define the group
and remember what group has already been defined. If we happen to have
to re-define the same group, skip it. Since we are traversing the list
in reverse order, this should make sure the last definition wins.
This has the benefit of being more performant and hopefully helps with
e.g. #1779 and similar issues.
At the moment you can never be sure whether you look at the results
that ale just produced after your last changes or you are looking at
outdated information.
Instead of showing the last results while ale executes checks on the
current buffer it can now show a specific indicator.
This commit introduces the new config variable
`g:airline#extensions#ale#checking_symbol` which defaults to "...". In
case you don't want to see this, you may set it to an empty string.
This will make sure that the current window will be highlighted as
expected, even if there are no other windows and all highlighting groups
will be correctly re-created as 'inactive'
references #1807
Previously the ale refresh was triggered after user interactions only.
When linting takes some time and the user is not actively working the
ale information was not updated while the things ale directly controls
were updated. This change makes showing linting results a loot smoother.
When switching away from Vim and your terminal supports the FocusLost
autocommand, set the statusline to inactive, so it won't distract you
too much when working with another application.
In the gui, the FocusLost autocommand should always trigger.
This is now the default, if people start complaining, that behaviour
should probably be made configurable.
closes#1807
for older Vims, the wordcount extension falls back to `g<c-g>` and
parses the messaage that is generated.
When doing so, it expects the English locale, which might not be true.
Therefore, try to regex parse the result without using the english words
(assuming the output is still in the same order as in English).
Compatibility:
- Don't use a script-local function to update the format strings
- Protect against `:normal!' moving the cursor on on the wordcount check
Bugfix:
- Let to_string() try to return something for all values
- Now returns correctly when passed both 0 and '0'
Upkeep:
- Simplify check again no valid key from winwidth()
- Old wordcount check: use matchstr() - more expressive and fewer steps
- Improve documentation style/clarity/detail
v:t_list is an internal variable describing the type of a list.
Unfortunately, this is not available in older vims. So let's fall back
to using `type([])`
see #1795
This prevents a warning message, when the function is tried to add
several times. Also while at it, add a '!' so that no error is thrown if
the file is sourced a second times.
commit bcd37fc115 changed the detection of modes slightly in that it
allowed not only single letters but also several letters.
While in theory, it might be okay to have extra modes displayed like
Insert Completion or Normal Insert, or Operator Pending, let's for now
just revert it to the default. We can always enhance it later if
requested.
Checking for wordcount changes now uses a b:changedtick comparison in
the statusline funcref. The autocommand strategy that used to do this is
removed, simplifying the code.
- Formatter is now only called when the wordcount changes
- ...#apply() now only compares against the filetype list when necessary
- Old format() function is no longer called for (unsupported) counting
of visual words
- Misc code quality improvements
Various improvements:
- Seperate out visual mode detection.
- Use TextChanged rather than CursorMoved where supported.
- Let users specify the filetypes for which wordcounting is enabled
with a list rather than a pattern.
- Move the filetype check to when airline is refreshed, as opposed to
on every update; autocommands are not created if wordcounting is
disabled
Currently the formatter, and not the wordcount plugin, is responsible
for providing the wordcount as well as formatting it. The default
formatter allows visual mode word counting, although this is not
documented.
The new interface - a transform() function, allows the main wordcount
plugin to internalise this logic. Providing the wordcount simplifies
formatter implementations:
- All formatters can display the visual wordcount.
- Formatters do not have to worry about compatibility with different
vim versions.
The old format() function can now be deprecated, although the wordcount
plugin retains compatibility with formatters using it. The default
formatter will also be used as a fallback if no suitable function is
found.
The default formatter is rewritten to use the new interface.
Add 'arduino' filetype to list of C-like languages. This is needed in

for some reasons, calling async functions might cause an error, if a

- Make sure to always call the term extension on TermOpen autocommands
- consistently use the airline_term highlighting group
- hard code the airline_term highlighting group, because by the time the
function airline#themes#patch() is called the highlighting group
airline_c would no be defined, so we cannot dynamically get those
attributes
- In the documentation, mention how the g:airline_mode_map can be set
including the terminal section
The default formatter uses a hand-build regexp for shortening the path
in the tabline. However, since it uses the \w regex atom, this won't
match e.g. cyrillic letters.
To fix this, use the builtin pathshorten() function which does handle
this case correctly. For a test, use e.g. 'D/Учёба/t.c'
closes#1737
this caused that the branch extension was not correctly working anymore
because of a refactoring of fugitive tpope/vim-fugitive@5d11ff7
Solution: Move the existence check for the fugitive plugin into a
separate function and call it from there in all places that check the
fugitive plugin. Do the same for lawrencium and vcscommand check.
fixes#605#1739
Startify unfortunately does not set the buftype option, so the
`[noperm]` would be shown, since the buffer is not really a file.
(see mhinz/vim-startify#324)
So allow to blacklist startify from this setting. To do so, the logic
from the tabline extension was refactored out into a separate function
that returns true, if the buffer matches
`g:airline#extensions#tabline#ignore_bufadd_pat` and that function is
then reused for the readonly() function as well.
Recently, NERDTree added the &readonly setting to its buffer.
Unfortunately, this caused airline to render the '[noperm]' string in
it.
Fix this by only making the readonly check for buffers that actually
represent files (e.g. the buftype option is empty).
Instead of requiring each version control plugin to modify airline to
show the current branch, provide a customization function we can check
instead.
Following the example of airline_theme_patch_func, you define the
variable like so:
let g:airline#extensions#branch#custom_head = 'david#svn#get_branch'
Custom functions should cache their value. They may need an autocmd to
invalidate their cache:
" Use a buffer-unique group name to prevent clearing autocmds for other
" buffers.
exec 'augroup svndavid-'. bufnr("%")
au!
autocmd BufWinLeave <buffer> unlet! b:svndavid_branch
augroup END
This change lets me integrate with vc.vim (I couldn't get VCSCommand
working for svn) or write my own thing for perforce.
Additionally, always load whole file and check for existence.
Instead of determining up front whether various scm plugins are
installed, check for them on use so they can be added after this script
is sourced.
This also mitigates the problem of checking for existence of autoload
functions (which are not loaded by exist()). Since we're checking
root-level functions, they're likely to be loaded once we're using any
part of the plugin.
275ec4fe63 broke this so that numbering
started from 0 instead of 1 with
g:airline#extensions#tabline#buffer_idx_mode = 1
Specifically, I overlooked that |index| actually tracked the index of
the current buffer in the buffer list *starting from 1*, whereas I
assumed it tracked the true index (starting from 0).
airline#extensions#tabline#buflist#list doesn't pick up some buffers
(most notably Netrw buffers), so there are sometimes no buffers to show
and the tabline code fails with an error. This avoids that situation.
It would be better to detect these and show titles for them, but for now
this restores the old behaviour.
previously, the branch extension used name[0:6], however that would
break with multibyte characters, since this is a byte index and not a
character index.

This also adds a compatability wrapper, so that versions older than

buffer name again.

This fixes the conflict of both plugins redifining the 'file' (or 'path')
function. Closes#1670.
As fugitiveline modifies the path display and bufferline replaces it,
the latter should be the plugin to be used if both are activated.
A new variable named cursormode_mode_func is used to store the function
returning the current mode. This allows more customization in the mapping.
The default value is the built-in mode function so there is no change in
behavior.

fixes#1629
commit ab49a1c7ae changed that no leading whitespace was added.
While this removed a double space in front of the current active
selected buffer, it removed one space too much for the non-current
buffers in the bufferline.
So partly reverse it and only add the space, if the highlighting groups
between each item did not change.
previously, when both tabs and buffers were displayed in the tabline, it
was not immediately obvious which side belongs to a buffer and which one
to a tab. Therefore, add [buffers]/[tabs] labels consistently.
under certains circumstances it could happen that for the vim-ctrlspace
tabline extension a tabline group was redefined which would cause a
separator having foreground and background color swapped. This was
caused by using the 'pos' parameter for the right side wrongly.
fixes#1559
rather let them be defined whenever they are needed. They were only used
inside a single function anyhow, so it does not make sense to cache
them. In addition, having the user later change the variable won't work
as expected.
The initial reason in #237 is not valid anymore, as vim-gitgutter
functions as expected for editing files that are not part of a repo,
whether they are:
- in a different repo
- in a parent repo (cwd being a submodule)
- outside of the repo
Furthermore, removing this check allows to show relevant info for
specific fugitive file names that are fugitive://..../sha1//...
which are hard to parse manually, especially in complicated situations
such as submodules.
The function shows the line number of the first error/warning that appears in the current buffer. If there are 20 warnings and the first warning exists on line 33, then vim-airline would show "W:20(L33)".
One can change how the line number is represented using: `g:airline#extensions#ale#open_lnum_symbol` and `airline#extensions#ale#close_lnum_symbol`
commit 7d082c03b2 added a workaround to skip
a few redraws on startup so that the intro message is not shown anymore.
However might cause problems, that some highlighting groups are not
correctly set. Also recent Vims (8.0.1290 and so on) do not seem to
suffer from the problem that an too early initializiation of airline
causes a redraw which skips the intro message.
Therefore, revert that commit.
Fixes#1585
skip anything that matches abort
e.g. running hg qtop with Vims path outside of the repository returns
something like "abort: no repository found in ..."
in that case, do not show anything.
commit 232b641 did unfortunately disable tagbar completely, since
exists("*func") does not autoload the function.
So this time, try explicitly calling the function once, and if it does
not exists, it should be disabled and not cause any further errors.

workaround with index(term_list(), bufnr('')) > -1 not needed anymore,
since vim 8.0.936 will correctly return 't' for the mode() function in
the terminal.
This enables the highlighting caching only when the variable
g:airline_highlighting_cache is set to 1
Should make airline faster and more performant, because we can save a
lot of expensive C core calls. However, when redefining highlighting
groups, it might not correctly reset the cache.
do not access get() function twice. We can assign the result to a
variable and use it a second time. Should speed up the highligther part
of the code by a bit.
Since I was already touching s:Get(), also get rid of the default

Currently this is a hack, to get terminal mode from Vim.
However there is no better solution yet, since the API is not stable
here. Until then, just use the hack with

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:

Commmit a10d321809 introduced a small typo
spelling a previously set variable `trailing_fmt` as `trailing_fm`. This
causes Vim to report `trailing_fm` as an undefined variable. In this
change, the variable is properly referenced as `trailing_fmt`.
calling settabvar() while evaluating the 'tabline' setting apparently
causes flicker on Windows. Fall back to using `:let t:var` to store the
content in the current tabpage.
This is not as good as using `settabvar()` since we cannot store the
title for other tabs, but at least it should prevent the flicker and at
the same time at least cache the title for the current tabpage.
do not call airline#extensions#branch#head() but instead use the cached

Note: it looks like GitGutterGetHunkSummary() could need some cacheing
The comparison in airline#highlighter#exec() was there to prevent to
call out to too many :hi calls by making sure that the newly to be
defined highlighting group will be actually different from the current
existing one.
However, that did not work, as the returned old highlight
group did never match the newly to be created one, since it
intentionally left the cterm attributes out for the gui and the gui
attributes for the terminal.
Therefore, fix the comparasion and make it compare the actual values
that we have.
This should make vim-airline a bit faster (hopefully!)
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 airline is initialized too early and some :hi commands are run,
this will force a redraw in Vim which will result in the intro screen
being cleared.
Currently, this does not work for gvim, not sure why.
closes#1476 (well only partly, until i have discovered, why for gvim it
doesn't work).
previously we only checked, that the group exists, however
if loading a new color scheme, this might lead to the group becoming

not show anything. Therefore, also check that the group is not cleared.

vim-airline does use a different section (path/file) depending on
whether 'acd' is set. Later in the bufferline extesion however, it
unconditionally overwrites the 'file' section, regardless of whether
this section is actually used.
Therefore the bufferline section needs to check this option as well.

Basically what the title says. First check if the user has Powerline,
fall back to Unicode symbols if he doesn't and fall back to ASCII

Vim-airline is not a looker without a Powerline font. This fixes that!

* New branch (ᚠ), line (㏑), maxline (☰) and whitespace (☲) symbols
* Replace old whitespace (✹) symbol in Powerline with the new (☲) more logical one

attribute was the same as the current one. However, if the group does
not exist, it should still be defined

If a color value of ['', '', 'NONE', 'NONE', ''] is given as value to
the highlighting group, the resulting group definition would look like
this:
hi Normal ctermfg=NONE ctermbg=NONE
which would result in the highlighting group being cleared (or even no
set at all), therefore check that at least one other value exists and if
not fall back to the highlighting definition of the Normal group.
Line numbers are now displayed before the error, instead of after, preventing truncation (and thus making the whitespace/indent section essentially useless in smaller terminals)
This was used as a workaround to fix a highlighting bug, which was fixed
in Vim 7.4.1511 and therefore, we need to correctly detect that the
patch was applied and in that case skip adding those extra groups.
As a bonus, when not using those empty %( %) groups, the
skip_empty_section test will correctly handle this and therefore this

Repro steps:
1. Install some theme that depends on the background color
(Soares/base16.nvim has a bunch)
2. `set background=dark` in your vimrc, and `colorscheme` one of the
aforementioned schemes.
3. Open a split window. Note the colors on the inactive window's airline.
4. `set background=light` manually. note the colors on the inactive
window's airline. Note how they have not updated. (In particular,
airline_c_inactive has updated, but all the other inactive groups
have not.)
5. Enter the inactive window. Exit the inactive window. Observe that the
colors are now correct (showing that it is in fact a problem with the
airline load_theme code, and not with the theme).
It seems strange that the code as written only expects
airline_c_inactive to have styling; perhaps there is some norm that
themes are supposed to handle inactive windows in a particular way? For
the record, my theme dis omething like this:
```
let s:IA1 = s:airlist('similar1', 'similar2')
let s:IA2 = s:airlist('similar1', 'similar2')
let s:IA3 = s:airlist('similar1', 'similar2')
let g:airline#themes#{s:palette}#palette.inactive = airline#themes#generate_color_map(s:IA1, s:IA2, s:IA3)
let g:airline#themes#{s:palette}#palette.inactive.airline_warning = s:airlist('base', 'contrast3')

airline#extensions#tabline#excludes and

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).
A typical status line for a 'po' (Portable Object) translation file is:
1152 translated messages, 91 fuzzy translations, 42 untranslated messages.
Adding a substitute(), tidies this to:
1152 translated, 91 fuzzy, 42 untranslated
which is still informative, but less verbose.
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.
Since Vim8 we have win_getid() and getwininfo() functions to get
information about the current window. So we can use those functions to
find out, whether the current window is a quickfix or location list
window.
This avoids using a redir() over the :ls command and trying to
manually match the string quickfix and should be faster and also be more
robust, as the redir may fail if done recursively.

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.

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.

[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.

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
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
