The tray manager of polybar listens on multiple atoms for the background of the root window. On change of these atoms, it will redraw its window-background and message its tray-client to redraw also.
On fast changes of of background, this leads to immense messaging and eventual flickering of the systray.
This patch tries to soften the issue in a way, that tray-window and its client will only redraw, if the bar has transparency. If not, there should be no reason to redraw on wallpaper-change.
* Redraw on background change only if transparent
* Replace tab with spaces
If a script module is waiting on a non-tailed script to finish, polybar
cannot shut down until the script has terminted.
To remedy this, we use the same polling loop as for tailed scripts which
checks if it needs to terminate after every iteration.
CMAKE_EXE_LINKER_FLAGS contains, among other things, the LDFLAGS which
many distros use to universally apply linker flags.
When completely replacing CMAKE_EXE_LINKER_FLAGS, these flags are lost.
Otherwise we get errors like this:
CMake Error at doc/cmake_install.cmake:46 (file):
file INSTALL cannot find
"/<<PKGBUILDDIR>>/build/doc/html": No such file or
directory.
Call Stack (most recent call first):

`-Wdeprecated-copy` found this copy-assignment operator, which it
complains about. Since it is just `= default`, we should be able to
remove both it and the default constructor, making the struct just its
data members.
If any action block contains a negative offset, it can cause text to be
theoretically be rendered outside of the block, making that text not
clickable.
To fix this, we ensure that an action block starts at the lowest
observed position while the block is open and ends at the highest
observed position while it is open.
Fixes#1814
When polybar is remapped (either through IPC or something like xdo
show), openbox positions it somewhere on the screen using the same
positioning algorithm as it would for regular windows.
If the position and size is set in the WM_SIZE_HINTS atom, openbox will
respect the position and size declared by the window.
Fixes#2021
* add units support (POINT, PIXEL, SPACE) for polybar
- add a size_with_unit struct
- add a geometry_format_values struct
- move dpi initialisation from renderer.cpp to bar.cpp
- add a string to size_with_unit converter
- add point support (with pt)
- add pixel support (with px)
* Fix unit test compilation
* clang-format
* Better names
The old names didn't really capture the purpose of the structs and
function.
space_type -> spacing_type
space_size -> spacing_val
size_type -> extent_type
geometry -> extent_val
geometry_format_values -> percentage_with_offset
* Remove parse_size_with_unit
No longer needed. The convert<spacing_val> function in config.cpp
already does all the work for us and always setting the type to pixel
was wrong.
In addition, line-size should not be of type spacing_val but extent_val.
* Cleanup
I tried to address most of my comments on the old PR
* Fix renderer width calculation
We can't just blindly add the x difference to the width because for
example the width should increase if x < width and the increase keeps
x < width.
Similarly, we can't just add the offset to the width.
* Rename geom_format_to_pixels to percentage_with_offset_to_pixel

* config: Use stod for parsing percentage
* Use stof instead of strtof
* units: Fix test edge cases
* Remove unnecessary clang-format toggle
* Use percentage_with_offset for margin-{top,bottom}
* Support negative extent values
* Rename unit to units and create a cpp file
* Move percentage_with_offset_to_pixel unit test to units
* Add unit tests for units_utils
* Clarify when and how negative spacing/extent is allowed
Negative spacing is never allowed and produces a config error.
Extents allow negative values in theory, but only a few use-cases accept
it.
Only the extent value used for the `%{O}` tag and the offset value in
percentage_with_offset can be negative. Everything else is capped below
at 0.
The final pixel value of percentage_with_offset also caps below at 0.
* Fix parsing errors not being caught in config
* Print a proper error message for uncaught exceptions
* Cleanup module::get_output
All changes preserve the existing semantics
* Stop using remove_trailing_space in module::get_output
Instead, we first check if the current tag is built, and only if it is,
the spacing is prepended.
* Remove unused imports
* Restore old behavior
If there are two tags and the second one isn't built (module::build
returns false), the space in between them is removed.
For example in the mpd module:
format-online = <toggle> <label-song> foo
If mpd is not running, the mpd module will return false when trying to
build the `<label-song>` tag. If we don't remove the space between
`<toggle>` and `<label-song>`, we end up with two spaces between
`<toggle>` and `foo`.
This change is to match the old behavior where at least one trailing
space character was removed from the builder.
* Add changelog entry
* Remove unused setting
* Use percentage with offset for tray-offset

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.

This only happens for commands and empty actions.

The socket file is not deleted after socket.close() is called, only
after libuv executes the close callback.
So we can't just call rmdir because it will probably always fail.

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.
