Lots of things were already under the `kaleidoscope` namespace, but were in the "wrong" directory. This big patchset moves everything under `kaleidoscope/`, and namespaces `Layers_`. There are a few un-namespaced things, but because their use is so widespread, and they're used so commonly, we don't want to namespace those (like `handleKeyswitchEvent`), at least not yet. As a minor side-effect, this moves a few global statics that were once in `Layers.cpp` into the `Layer_` class itself, for clarity and encapsulation. Non-namespaced headers that were used outside of Kaleidoscope itself will still work, but will emit a compile-time warning. Signed-off-by: Gergely Nagy <algernon@keyboard.io>pull/364/head

|

* First of all, we use caches because looking up a key through all the layers
|

* is costy, and the cost increases dramatically the more layers we have.
|

*
|

* Then, we have the `liveCompositeKeymap`, because to have layer behaviours
|

* we want, that is, if you hold a key on a layer, release the layer key but

* continue holding the other, we want for the layered keycode to continue
|

* repeating.
|
||||
*
|
||||
* At the same time, we want other keys to not be affected by the
|

* now-turned-off layer. So we update the keycode in the cache on-demand, when
|
||||
* the key is pressed. (see the top of `handleKeyswitchEvent`).
|
||||
*
|
||||
* On the other hand, we also have plugins that scan the whole keymap, and do
|
||||
* things based on that information, such as highlighting keys that changed
|
||||
* between layers. These need to be able to look at a state of where the
|
||||
* keymap *should* be, not necessarily where it is. The `liveCompositeKeymap`
|
||||
* is not useful here. So we use `activeLayers` which we update whenever
|
||||
* layers change (see `Layer.on` and `Layer.off`), and it updates the cache to
|
||||
* show how the keymap should look, without the `liveCompositeKeymap`-induced
|
||||
* behaviour.
|
||||
*
|
||||
* Thus, if we are curious about what a given key will do, use `lookup`. If we
