* 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 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

This only happens for commands and empty actions.

* 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.

* Implement dimming using timer handles
* Remove taskqueue

* Cleanup & Comments
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).
* Add toggle_visible action
* Add set_visible and set_invisible actions
* Rename toggle_visible method to match
`action_toggle_visible` -> `action_toggle_visibility`
Matches with `EVENT_TOGGLE_VISIBILITY`
* Update CHANGELOG
* Revert #2320 IPC commands
IPC commands are no longer necessary now that the actions are
implemented. Changed some method permissions as well to reflect this.
* Add logging and change action names
- `module_toggle`
- `module_show`
- `module_hide`
Delineate common actions to all modules with a `module_` prefix (for
future actions too)
* Update documentation
* 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
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.
Ref: #770
Ref: #1680
Only modules can now be action handlers.
This also slightly simplifies the controller because we don't need to
keep track of input handlers, we can just use the module list.
