If two users start a bar with IPC and don't have XDG_RUNTIME_DIR set,
polybar will create the fallback directory `/tmp/polybar`.
However, that directory is only accessible by the user that created it
and so polybar running under the second user will fail to open its
socket there.
We add the UID to the fallback directory to prevent this.
Fixes#2683
If only cursor-click or cursor-scroll is defined, but not the other, the
bar could try to set the cursor to the empty string which resulted in an
error.
Because the X server is asynchronous, there is no guarantee that after
reading _NET_CLIENT_LIST, all windows still exist.
For that reason we need to handle XCB_WINDOW errors appropriately.
Since polybar sets WM_NORMAL_HINTS, awesomeWM for some reason no longer
respect the position set by polybar before mapping.
reconfiguring the window position once again after mapping the window,
again positions it correctly.
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.
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
* Cleanup

* config: Use stod for parsing percentage

* 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

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.
Non-empty actions are not immediately executed, but deferred until the

* Remove TODO about deleting runtime directory
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.
* CLeanup WriteRequest
* Update manpage authors
* 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
