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
* 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
All modules now expose their actions as public static constants
Issues: The menu module no longer closes when an item is clicked (before
it would intercept any executed command and look if it matches one of
its exec commands)
Removing monitors is not really necessary when selecting the monitor
where to render the bar or choosing the backlight. Since both monitors
occupy the same coordinates rendering can be done on both and it's
better to give people felxibility for the backlight.
Fixes#1191
This adds `monitor-exact = true` in the bar section
This also properly does best-match instead of first-match if multiple
matches exists. For example if there are two monitors HDMI2 and HDMI-2
and we try to match HDMI-2 with monitor-exact = false, until now HDMI2
would be matched. Now exact matches are always preferred.
Fixes#1532
Be less strict when matching randr outputs
against specified name. This is a workaround
to fix the output naming issue when switching
between graphic drivers.
On my system the output names include a dash
when using the nvidia drivers but the intel
driver does not.
nvidia:
HDMI-1
eDP-1
xf86-video-intel:
HDMI1
eDP1
When strict mode is disabled the matching
won't care about the connection state.
The user can re-enable exact matching and
connection state testing by setting the
config parameter `monitor-strict = true`
