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.
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.
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.

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.

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

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
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

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.

Use std::make_shared.
The eventloop no longer uses them. libuv will coalesces multiple
uv_async_send if they happen one after another and this also leads to
coalescing of updates.
This is needed because the handle's lifetime has to be at least the
lifetime of the eventloop since the eventloop requires the handle's
memory during shutdown (for closing the handles).

* fix(monitor): do not include outputs when monitors are supported
Previously, when splitting an output into two monitors, `polybar -m`
would report both the splitted monitors and the output. This was not
caught by the the clone detection as the detection works by removing
monitors contained into another monitors (and monitors were excluded
from that logic) and we want the other way around: outputs covered by
monitors should be ignored.
Instead of trying to detect covered outputs, the solution is quite
simple: when monitors are supported, do not consider outputs, unless
we request all outputs. A monitor can be set primary (and RandR
reports primary outputs as primary monitors). The only information we
would miss from monitors are things like refresh rate and EDID. We
don't need that, so we are fine.
As monitors are only created for connected output (and they are in
this case "active") or disconnected output if they are mapped (and
they are in this case "inactive"), I am a bit unsure if we have
exactly the same behaviour as previously when `connected_only` is set
to `false`.
As some modules require an output, we keep the output in the
`monitor_t` structure and we ensure it is correctly set when using
monitors. A monitor can have 0 or several outputs. We only handle the
0 and 1 cases. When a monitor has more outputs, only the first one is
used. AFAIK, only the xbacklight module needs that and I think we are
fine waiting for a user needing this module and merging monitors.
The C++ binding fail to expose the `outputs()` method to iterate over
the outputs of a monitor. This seems to be a bug in XPP. The field is
correctly defined in the RandR XML file and it works with the Python
binding.
```xml
<struct name="MonitorInfo">
<field type="ATOM" name="name" />
<field type="BOOL" name="primary" />
<field type="BOOL" name="automatic" />
<field type="CARD16" name="nOutput" />
<field type="INT16" name="x" />
<field type="INT16" name="y" />
<field type="CARD16" name="width" /> <!-- pixels -->
<field type="CARD16" name="height" /> <!-- pixels -->
<field type="CARD32" name="width_in_millimeters" />
<field type="CARD32" name="height_in_millimeters" />
<list type="OUTPUT" name="outputs">
<fieldref>nOutput</fieldref>
</list>
</struct>
```
Falling back to C only to access the list of outputs is not enough
because the list is appended to the structure and not visible through
the public API. When copied, the structure loses the list of monitors.
Also, change the mention "XRandR monitor" to "no output" when there is
no output attached. People using monitors know what it means and it is
useful to catch a future regression where we don't have an output at
all (which would break the brightness plugin).

This adds the 'send' action to the ipc module that can be used to send arbitrary text to the module:
polybar-msg action "#ipc.send.%{F#4444ff}hello%{F-}"
* feat(ipc): allow receiving arbitrary text on IPC socket
Instead of just allowing hook numbers to be executed, the user can
send arbitrary text and the IPC module will put it in the bar. The IPC
payload format is extended to accept an arbitrary string if the first

XCB_BACK_PIXMAP_PARENT_RELATIVE requires that the client has the same
depth as the tray window.
There was an issue with dropbox having a depth of 32 and the tray window
having a depth of 24 that caused the configuration of the icon to fail.
It would then be displayed outside of the bar because the catch block
was not hit (different exception).
We now just don't configure XCB_CW_BACK_PIXMAP. This seems to work and
is also what stalonetray does.
This does not fix the issue with dropbox having an arbitrary background.

* Add wm-restack=generic to lower polybar to the bottom of the stack
Previously wm-restack only supported bspwm and i3. Both have a special
top-level window that polybar detects and places itself directly above.
This patch adds wm-restack=generic which simply lowers polybar to the
very bottom of the stack. This option was tested and confirmed to work
with xmonad which doesn't have a special top-level window and therefore
doesn't require special handling like bspwm and i3.

Fixes#2398
When `pin-workspaces` is set to true using `show-urgent` will show
urgent workspaces on the bar even when the workspace is not associated
with the current monitor.
The renderer now only stores the positions of the actions because that
is specific to the renderer and because the actual position can only be
finalized after all the rendering is done because intitially the
positions are relative to the alignment and not the bar.
The variables storing the current colors, attribute activations and font
were only used in a single place and can easily also be read from the
context.
This allows us to remove a lot of the state of the renderer.

* module: Implement proof of concept action router
Action implementation inside module becomes much cleaner because each
module just registers action names together with a callback (pointer to
member function) and the action router does the rest.
* Make input function final
This forces all modules to use the action router
* modules: Catch exceptions in action handlers
* Use action router for all modules
* Use action_ prefix for function names
The mpd module's 'stop' action overwrote the base module's stop function
which caused difficult to debug behavior.
To prevent this in the future we now prefix each function that is
responsible for an action with 'action_'
* Cleanup
* actions: Throw exception when re-registering action
Action names are unique inside modules. Unfortunately there is no way to
ensure this statically, the next best thing is to crash the module and
let the user know that this is a bug.
* Formatting
* actions: Ignore data for actions without data
This is the same behavior as before.
* action_router: Write tests
Modules can now also be shown and hidden using ipc commands:
$ polybar-msg [-p PID] cmd hide.mymodule # Hides module mymodule
$ polybar-msg [-p PID] cmd show.mymodule # Shows module mymodule
$ polybar-msg [-p PID] cmd toggle.mymodule # Toggles visibility of mymodule
* Hopefully implement visibility checking
* Implement hide command
* Implement `show` and `toggle` commands
* Refactor and add some logging
* Run style checks and update CHANGELOG
* Get around unused parameter warnings
* Change `set_visible` to return nothing
* Make errors more informative

The intention was to remove tags that won't have an effect and join
together consecutive tags.
However the patterns used can just as well appear in regular text, so
this can replace characters inside user defined text and not just
formatting tags.
Fixes#2331
Each major target of polybar can now be enabled/disabled while
configuring (even polybar itself).
The cmake code specific to each target will only run if the target is
enabled.
This allows us to for example just build the documentation without
having to run all the cmake code related to compilation or having the
polybar dependencies installed (other than sphinx).
* Added .ini extension check to default config
* Added change to changelog and man page
* Added change to changelog and man page
* removed .vscode folder
* removed new lines in changelog
They were required before, but could technically be deactived (the
compilation would fail, but configuration was possible).
The WITH_XRANDR and WITH_XCOMPOSITE now no longer appear in the cmake
part. It still appears in the source code, but is always set to 1
Fixes#1536
* Add variant support to xkeyboard layout label
Solves #316
* Run style checks, I guess?
* Add comment
* Return nothing if there is no variant
* Update CHANGELOG
* Fix xkeyboard module spacing between the layout and indicators when indicators are empty.
* Simplify the empty label check.
* Remove permanently enabled SCROLL_LOCK, sorry.
* Another mistake.
* Update src/modules/xkeyboard.cpp

* refactor(color): Use enum class for color type
* Add testcases for tag parser
* Make tag parser a pull-style parser
Being able to parse single elements at a time gives us more fine-grained
error messages, we can also parse as much as possible and only stop
after an exception.
* fix(color): Parser did not check for invalid chars
* tag parser: First full implementation
* tag parser: Fix remaining failing tests
* tag parser: Replace old parser
* tag parser: Treat alignment as formatting tag
Makes the structure less complex and the alignment tags really are
formatting tags, they are structurally no different from the %{R} tag.
* tag parser: Cleanup type definitions
All type definitions for tags now live in tags/types.hpp, the parser.hpp
only contains the definitions necessary for actually calling the parser,
this shouldn't be included in many places (only places that actually do
parsing). But many places need the definitions for the tags themselves.
* Rename components/parser to tags/dispatch
* tag parser: Cleanup
* Add changelog
Since the forked processes are still our children, we need to wait on
them, otherwise they become zombie processes.
We now fork twice, let the first fork immediately return and wait on it.
This reparents the second fork, which runs the actual code, to the init
process which then collects it.
Ref #770
For some reason when passing some non-const strings to convert, the
convert(T&& arg) method was used instead of the one specialized for
strings.
This caused an error in clang because you can't pass objects with
non-trivial types to varargs functions.
The best solution I found was to just add a specialized function for
non-const strings.
This was a backwards-incompatible change introduced in #2199, however it
was caused because `module_formatter.has` throws an exception when the
format doesn't exist instead of just returning false.
Fixes#2262
Ref #2199
If two WM events arrive withing 25ms of one-another, the second one does
not trigger a bar update.
The module state is still correct, it is just not reflected in the bar.
This somehow caused updates being swallowed in fluxbox, but only after
PR #882 was merged, even though that 25ms restriction existed long
before that.
Fixes#2272
Since 3.5.0, we use m_interval for a modulo operation, this crashes the
bar if the interval is 0. A non-positive interval shouldn't be allowed
anyway, so we now throw an exception in that case.
Fixes#2273
Pre 3.5.0, any key starting with 'inherit' was treated as an inherit
directive. This allowed for multiple inheritance even though it was
never inteded in that way.
3.5.0 removed that bug/feature by doing a strict check against 'inherit'
It seems people were relying on this behavior, so we are adding it back.
However multiple inheritance with multiple keys is also deprecated in
favor of the `inherit` key now supporting multiple space separated
sections.
This is because the config doesn't have a key order, but inheritance
does depend on the order the different section keys are copied over (if
multiple inherited sections define the same key).

It was not quite clear how try_apply_alpha should behave if the given
color was not ALPHA_ONLY. The implementation just returned 'this'.
However, the build relied on it returning the given color.
This broke all bg and fg settings in the entire bar.
To clear this up, we switch this around take the alpha channel of 'this'
and also return 'this' if it isn't ALPHA_ONLY.
Fixes#2255
New config option `speed-unit = B/s` will be used to suffix the upload and download speeds.
* mod::network: udspeed-unit to set network speed unit suffix
* Changed udspeed-unit to speed-unit
Shell commands triggered from action tags used to block polybar until
they finished.
Since we are not actually interested in the output of the commands, it
makes sense to run them completely detached from polybar and have
polybar not block when executing these commands.
Now the spawned child processes no longer get killed when polybar
exits. This is fine because polybar is not responsible for these
processes since they were explicitly started by the user through click
commands.
