### Description
|
|
Enables hot-reloading of dwl; meaning almost all logic can be changed at runtime.
|
|
This obviously requires some black magic so for now there's a glibc 2.0 or later
|
|
dependency to this.
|
|
In particular this allows for every option in config.h to be changed at runtime.
|
|
|
|
#### Reloading
|
|
To reload rebuild dwl.so, perhaps reinstall it and then run trigger reload function (bound to Mod+Shift+R by default).
|
|
This currently calls `notify-send` in order to inform you of a reloading taking place.
|
|
So in short:
|
|
1. make changes to `config.h` or `dwl.c`
|
|
2. run `make` to rebuild dwl.so
|
|
3. run `sudo make install` to reinstall dwl
|
|
|
|
|
|
#### Limitations
|
|
Reloading the compositor will replace all functionality except for `main`, `setup`, `run` and the reload logic.
|
|
Note that you're responsible yourself for reloading ressources like fonts, which may only get acquired once.
|
|
A lot of components of dwl will also only get run on a trigger (the tiling for example).
|
|
So not every change will be immediate.
|
|
|
|
#### Notes
|
|
##### reduce compile errors
|
|
This patch triggers `-Wpedantic` a bunch (I don't think there's a way around this, `dlsym` yields `void*` pointers to functions).
|
|
This will show a lot of warnings but cause no errors.
|
|
So you may want to disable this compile option in order to get readable compiler output.
|
|
##### runtime dependencies
|
|
This does depend on you having a notification daemon like `dunst` or `mako` running as well as
|
|
having `notify-send` installed in order for the compositor to inform you of the reload.
|
|
|
|
#### How?
|
|
Most of all dwl functionality is moved into a shared object file `dwl.so`, which can be reloaded at runtime.
