Defer parsing the version read from version.txt until it's about
to be used, in order to fix an obscure bug involving indirect
pkg_resources.
When pkg_resources are imported, they override packaging with their own
pkg_resources.extern.packaging. Depending on the system, this could
either wrap the vendored pkg_resources._vendor.packaging or system
packaging. For some reason, in the latter case the Version objects
created prior to the wrapping are incompatible with the objects created
afterwards. This causes the doc build to fail with:
```
Exception occurred:
File "/tmp/polybar/build/doc/conf.py", line 249, in run
if directive_version > version_txt:
TypeError: '>' not supported between instances of 'Version' and 'Version'
```
This happens because apparently pkg_resources are imported indirectly
somewhere between conf.py processing and running VersionDirective.
Deferring version parsing until the latter guarantees that both objects
are constructed at the same point in program flow and therefore use
the same packaging package.
If two processes call `mkdir` at the same time, the second one will fail
and wrongly assume the folder wasn't created properly.
We now first check if the folder really doesn't exist and we also catch
any IPC initialization errors and disable IPC instead of crashing the
whole bar.

* Cleanup
Improve the find_interface() to return a interface name
that is currently running if any interface of given type
is currently running, else just return the first one found.
This will allow the interface-type to work with multiple net interface
of the same type, and prefer to one that is currently connect to
a network. This works great HW with multiple ethernet port and user
expect to occasonally swap between the two.

This fixes#857 and #1932. Also replaces PR #1725, since we don't need
our own implementation of condition_variable anymore since people who
update their polybar should have GCC 10 by now.
The m_updated_at field of the mpd module was removed instead of having
its clock change because it became unused in commit 645a3142a1.
This adds a new `tray-foreground` config option, and uses it instead of
the `tray-background` setting to build up the `_NET_SYSTEM_TRAY_COLORS`
property. I'm pretty sure that the previous behavior was a mistake (this
was introduced in 94298741b6 which is a
pretty large diff). For me and some other people, this results in a
black icon being drawn on top of a black background, which is pretty
useless! I would say that this diff fixes
https://github.com/polybar/polybar/issues/2235. Note: the old code dealt
with `unsigned int` and maxed values out at 0xff. The new code deals
with `uint16_t` and maxes values out at 0xffff. I haven't found the
relevant documentation to justify this change, but from manually
testing, I'm pretty confident this is the right change.
This all matches pretty closely with this code from i3:
[`i3bar/src/xcb.c::init_tray_colors`
code](43e805a00d/i3bar/src/xcb.c (L1490-L1522)),
which you can see also uses the bar's foreground color and maxes values
out at 0xffff, not 0xff.
If you merge this up, I think we should also update
https://github.com/polybar/polybar/wiki/Configuration#bar-settings to
mention the new settings.
Fixes#2235
I followed the instructions on
https://github.com/polybar/polybar/wiki/Testing, and this happened to
me:
$ cmake .. -DBUILD_TESTS=ON

It looks like the problem is that
[googletest](https://github.com/google/googletest/) changed their branch from
`master` to `main` at some point.
I also fixed a broken link
https://github.com/polybar/polybar/wiki/Testing. Hopefully it's
intentional that random members of the public such as myself are allowed
to do that?
We had a check that restricted config files to "regular files".
This check was to restrictive as it didn't allow for things like:
```
polybar -c <(gen_config)
gen_config | polybar -c /dev/stdin
```
Now, polybar can easily read config data from stdin.
* Handle relative includes
We change to the directory of the given config file before parsing.
This allows us to handle relative includes.
TODO: Maybe improve the name of the change_dir() function.
* Fix unused result warning
* Add `relative_to` parameter to expand()
If the path is relative, we resolve it by prepending
dirname(config) to the path.
Add dirname() - Returns the parent directory of the file or an empty
string.
* Resolve relative paths
Handle paths relative to the current file being parsed.
* Remove unneeded change_dir()
* Fix expand()
`is_absolute` is calculated after we expand the path.
`relative_to` must be a directory.
Add test for expand() with relative paths
* Recalculate `is_absolute` after expanding `path`
* Add more file_util::expand tests
* Add changelog

* ci: Use new codecov uploader
The bash uploader is deprecated
Ref: https://about.codecov.io/blog/codecov-uploader-deprecation-plan/
* Collect coverage report using lcov
* Remove branch coverage
There are a lot of hidden branches in the C++ code which doesn't make it
very useful
Before it was enabled by default. That means if the constructor fails,
the destructor will complain that the module was not stopped before
deconstructing.
We can't just call stop if module creation fails because the module is
only partially initialized.
* The xworkspaces module should wait for EWMH to become available
Before this change if EWMH wasn't available the xworkspaces module was
permanently disabled. When polybar was started alongside the window
manager e.g. from .xinitrc this caused a race condition between polybar
and the window manager and the xworkspaces module may or may not be
displayed. After this change polybar will wait for EWMH to become
available. This change closes#1915, see that issue for more details.
Curiously this only required the removal of the error condition which
used the be raised when EWMH wasn't available. The xworkspaces module
will show up on the bar as soon as the first EWMH event is processed by
the existing event handling code. I can't argue much about the
correctness of this patch but it seems to work flawlessly in my testing
with xmonad. I didn't test any other window managers. Note that removing
the error condition below which checks that _NET_DESKTOP_VIEWPORT is
available might make this work with pin-workspaces=true. I couldn't test
the effects of that change because I only tested with xmonad and xmonad
doesn't support _NET_DESKTOP_VIEWPORT, so I didn't make that change.
* xworkspaces: Remove check fo _NET_DESKTOP_VIEWPORT
Implementations that don't support it will just return an empty list for
get_desktop_viewports and pin-workspaces won't do anything.
* Update changelog

The previous CAST_MOD(Impl) for the action_router constructor was
illegal because `this` is not yet of type Impl (because the subclass
constructor has not run yet).
The action_router now accepts std::function for its callbacks.
Fixes#2519
Fixes#1978
* Move tail and non-tail handler to method
Defining them in the constructor is ugly.
* script: Iterate over defined actions instead of fixed list
* Separate running logic and lock m_output
* Include POLYBAR_FLAGS in linker flags
* Stop using m_prev in script_runner
* Join module threads in stop function
Joining in the destructor may lead to UB because the subclass is already
deconstructed but the threads may still require it to be around (e.g.
for calling any functions on the instance)
* Cleanup script module
* Update changelog
* Remove AfterReturn class
* Remove m_stopping from script module
* Fix polybar not reading the entire line from child process.
For every `readline` call we created a new fd_streambuf. This means once
`readline` returns, the streambuf is destructed and and pending data in
its temporary buffer discarded and we never actually read it.
* Remove unused includes
Returns a list of key-value pairs starting with a prefix.
If you have in config:
```
env-FOO = bar
env-CAT = dog
```
then `get_with_prefix("env-")` will return
`[{"FOO", "bar"}, {"CAT", "dog"}]`
* Remove DEBUG_SHADED
Was disabled by default AND behind an #if 0
* Make TimerHandle expose more libuv functions
* Prepare for moving double clicks into eventloop
