The member functions of the union now take all arguments const, meaning
that it is not possible to modify this value somehow. This reduces the
chance of subtle bugs and widens the contexts in which these member
functions can be used.
Furthermore, one signature took a `Key' by value while all functions
take `Key' by reference. For the sake of consistency, this was adapted
to.
Making the member functions of Key `const' explicitly flags that they
will not change the union. This will allow to use Key in const contexts.
Adding the `constexpr' specifier to the function makes it possible to
rely on the results at compile time. This puts some kind of restrictions
on the function, especially when using C++11 and not a newer standard,
but these restrictions were already fulfilled, so this seems to be safe.

With this redesign, we introduce a new way to create plugins, which is easier to
extend with new hook points, provides a better interface, uses less memory, less
program space, and is a tiny bit faster too.
It all begins with `kaleidoscope::Plugin` being the base class, which provides
the hook methods plugins can implement. Plugins should be declared with
`KALEIDOSCOPE_INIT_PLUGINS` instead of `Kaleidoscope.use()`. Behind this macro
is a bit of magic (see the in-code documentation) that allows us to unroll the
hook method calls, avoid vtables, and so on. It creates an override for
`kaleidoscope::Hooks::*` methods, each of which will call the respective methods
of each initialized plugin.
With the new API come new names: all of the methods plugins can implement
received new, more descriptive names that all follow a similar pattern.
The old (dubbed V1) API still remains in place, although deprecated. One can
turn it off by setting the `KALEIDOSCOPE_ENABLE_V1_PLUGIN_API` define to zero,
while compiling the firmware.

With the previous algorithm, once every 65 seconds, there would be a significant jump in
the brightness of the "breathing" LEDs as the 16-bit value recorded from `millis()`
overflowed. Instead of dividing by 12, I changed it to a bit shift (4 bits; equivalent to
division by 16), so when the integer overflow occurs, the next value is what it should be.
This is a somewhat unwieldy fix for all the out of bounds (attempted) array addressing at
both ends. When `pos` goes out of bounds in either direction, the test is the same because
it's an unsigned integer. However, after the change of direction, the trailing LED will
still be out of bounds, so we check that every time we call `setCrgbAt()` for `pos2`.
It's rather ugly, but it does ensure that we don't call `setCrgbAt()` with an
out-of-bounds address.
Before this change, we couldn't use the full functionality of the plugin's
warp feature to drag an item (by holding down a mouse button key). The
plugin would reset the warp state during each scan cycle, so we could
only warp the pointer to a cell in the top-level grid. This fix enables
warping repeatedly into sub-cells while holding a mouse button.
This prevents an insignificant error, but it is more correct to handle the integer
overflow instead of ignoring it. I've also changed syncTimer from a 32-bit to 16-bit
integer, which results in a smaller code size, and changed the computation of the timeout
slightly, so the LED update interval is always the same (we add `syncDelay` to the
previous update's start time, not it's end time), rather than varying based on when
LEDControl's `loopHook()` function is called relative to the last timeout.
There already exist 2 rainbow LED effects, this adds a third, using
the LED-Stalker effect.
When you press a key, the LED on that key will cycle through all the
colors of the rainbow, independent of the colors of other keys.
I had failed to check that the queue length was non-zero before checking release delay
timeouts, causing reading past the end of the `key_queue_` array an repeatedly sending
essentially random input to the host.
In the process of fixing that bug, I realized that I was also assuming that layer changes
weren't happening earlier in the queue and checking whether or not a key is a qukey when
it wasn't the head of the queue. Now we only enact a release delay when `flushKey()` is
called, and always call `setQukeyState()` when enqueuing new keys so that we can
distinguish between keys that should be immediately flushed in the primary state, and ones
that should have keypresses delayed.
When releasing a qukey, allow a short timeout in case a subsequent key was released
effectively simultaneously, treating that near-simultaneous release as intended to use the
alternate (i.e. modifier) keycode.
Any keyswitch events without real physical addresses were injected by other plugins and
should not be processed by Qukeys. There was an interaction with OneShot that prevented
the two plugins from working together because OneShot sends events with a (row, col)
address of `UNKNOWN_KEYSWITCH_LOCATION` (i.e. 255, 255). This meant that if a OneShot
modifier was on when a Qukey was pressed, it would fill up the queue with bogus-address
versions of the Qukey, which would then get flushed in the primary state, cancelling the
OneShot and producing an un-modified, repeating primary keycode, causing both plugins to
fail.

When a keyswitch has been off in the previous cycle and is still off now, do not

In practice, handling fully idle keys is not useful. There are many plugins
which explicitly look for this case and return early, because it isn't an
interesting event. As such, not calling the event handler in this case makes
sense, as we save not only a few needless checks in plugins, but our performance
improves greatly too.

When there are no state changes, and no keys pressed on a row, instead of
iterating through a byte bit-by-bit, just fire idle events without checking the
bits. In all other cases, do the bit-walking like we did before.
The reason this is useful is because bit-walking is costly, and slow. If we can
avoid that, we win quite a lot of performance. Since rows being idle is the most
common case on a keyboard, this is a huge net win. Even in the worst case, where
no rows are idle, this is just one byte comparison and a branch slower than our
previous implementation.
As part of this optimization, `actOnHalfRow` was lifted out into its own
function, to reduce code duplication.

I made a bunch of changes to improve SpaceCadet for the better.
1. I resolved issue #9 ( https://github.com/keyboardio/Kaleidoscope-SpaceCadet/issues/9 ) to support mappings on Alt keys under Windows. This change in behavior means that we don't send the initial key value (the key with a mapping) until we hit the timeout (if held) or if we hit another key in combination in the mean time (to keep modifiers working as expected in combination with other keys). This means that when you place a mapping on Alt, we don't send Alt if you are just tapping -- we only send the other key value. This prevents Alt capturing the menu bar in Windows apps, and probably means we can better support SpaceCadet on non-modifier keys.
2. I added support for enabling, disabling, and determining if SpaceCadet is currently enabled. This allows other plugins and macros to better interact with SpaceCadet, and allows us to temporarily disable the behavior if that's desired.
3. I added two new virtual Key entries for placing on the user's keymap. One key disables SpaceCadet, and the other key enables SpaceCadet.
I also updated the README.md with all of the relevant changes.
It seems that if we inject the release of the mapped modifier key before injecting the press of the alternate key, we avoid the need to call `hid::sendKeyboardReport`, which in turn fixes#7. Which is nice.

This restricts the data type of the enum to uint16_t, so if anyone ever adds enough values
to it to overflow the 16 bits that are available in the Key structure, even if they do it

error instead of runtime errors.
These macros were copied and pasted, I'm guessing from the USB HID Usage Tables document,

`AC Download (Save Target As)`. When automatically converted into a preprocessor macro, it

When the value returned by `millis()` overflows (after ~two months of runtime), a straight
comparison to the end time would fail. This wasn't a really big deal, but it is possible
to do it correctly, and in the process, reduce the size of the time values stored from 32
bits to 16 bits (~one minute), since the largest conceivable useful timeout is measured in
seconds (at most).
We need to prevent infinite loops, and also stop handling keyswitch events when flushing
the queue, but if we do this by setting the `INJECTED` bit in `keyswitch_state` when
calling `handleKeyswitchEvent()`, then other plugins will ignore those events, which is
not what we want; we need them to process those events as if they were real
keypresses. The solution is to use a static boolean to let us know if the queue is being
flushed.
As we guarantee backwards compatibility throughout a major version, it helps if
we have that version available, so plugins / sketches can check if they are
compatible, and issue a helpful error if they are not. As further convenience,
defining `KALEIDOSCOPE_REQUIRED_API_VERSION` before including `Kaleidoscope.h`
will result in a check being done by Kaleidoscope, and an error printed if it
does not match the API shipped.

KeyboardioHID isn't going to get a function to copy the previous

previous HID reports public. This is a much better solution all
around, as it allows us to save and restore the current report in the
midst of a scan, while still sending a modified version of the old
report.
`updateActiveLayers()` makes it impossible to turn off the default
layer, so there's no point searching past it for the highest layer,
and `defaultLayer` can be set to numbers higher than zero.
Now that `layer_count` is (potentially) available, we can start
looking for active layers at the top _defined_ layer instead of the
top _possible_ layer. This ought to be more efficient, especially for
sketches that don't have lots of layers defined.

By starting the lockout end timer at the moment of the last keypress

already spent not typing.
If we call updateLiveCompositeKeymap() on key release the keymap gets
updated before the release event occurs, and any ShiftToLayer(N) key
with a different definition on layer N won't work properly. Before its
release event is processed, it gets updated to the new value, and
layer N doesn't get turned off. If we only update the live keymap on
key press events, we don't have this problem.
replacing the Key_16bit macro with CONSUMER_KEY macro allowed us to

If it's an old sketch, LayerCount will default to 0, so in order for

LayerCount == 0.
Declaring LayerCount as a weak symbol in layers.cpp lets us override
it if the CREATE_KEYMAP macro is used to define the keymap in the
sketch file, but still allows old sketch files to compile without
errors.
Still some changes necessary to allow old sketches to work
properly (Layer.on() will abort before doing anything).
This macro allows the definition of the LayerCount variable and the

probably not all that's necessary; LayerCount still doesn't get

By moving the IS_CONSUMER flag to B00001000 instead of
B00000010 (swap with IS_INTERNAL) we can detect the if the key is a

saw, it was never used elsewhere, thus, this change should be safe.

As discussed in #190, and later on IRC, this renames ToggleLayer to

This introduces `ToggleLayer(n)` and `MomentaryLayer(n)`, which make it
easier to switch to layers higher than five, and allow one to use enum

`MomentaryLayer(FUNCTION)`.

Requiring the end-user to use a macro to have the NumLock effect is a bit
confusing. We can do better than that, by using an event handler hook, and
catching `Keypad_NumLock` presses, and toggle on keypress.
This way, the macro is not necessary, and all the user has to do, is to use the
plugin, configure `numPadLayer`, and done.

The plugin should not try to set the colors of a layer higher than

The `OneShot.isActive(key)` method was returning true even if a key timed out,
when `OneShot.isActive()` already returned false. It now takes the timeout into
consideration too.
Signed-off-by: Gergely Nagy <kaleidoscope@gergo.csillger.hu>
OneShot has a convenient way to tell us if any OneShot keys are active:
`OneShot.isActive()`. Thus, if we are using oneshots only, we can skip scanning
the whole keymap if no one-shots are active, saving us a whole lot of time per
cycle we would be spending needlessly.
The optimization is off by default, and must be turned on by the user's sketch.

We want to start with a pre-cached state, so we have both less work to do when

For all cases outside of Kaleidoscope itself, we are good with the value of
`highestLayer`, and do not need to re-scan the layer state. For this reason -
upon @obra's suggestion - rename `Layer.highest()` to `Layer.top()`, and the old
`Layer.top()` to `Layer.updateHighestLayer()`, and make the latter private, and
update the `highestLayer` member variable instead of returning the number.

Sometimes we would like to know the highest active layer, which is available in
the `highestLayer` private variable, and via `.top()` too. We do not want to
make `highestLayer` public, because we want to be the only ones changing it. And
while `top()` gets us roughly the same information, it does so at a cost. For a
lot of purposes, the cached `highestLayer` would be perfectly adequate.
The new `Layer.highest()` accessor does just this.
Signed-off-by: Gergely Nagy <kaleidoscope@gergo.csillger.hu>
Now that we only care about the highest active layer, make sure we only do work
if that changed between two cycles. This way, `onActivate()` will take care of
the initial setup, `update()` will be an almost no-op for most of the time, and
`refreshAt()` will take care of refreshing keys other plugins may have changed.
This makes us about twice as fast as we were, on average.

Instead of using `Kaleidoscope-Ranges` and custom helper functions with magic
constants to decide whether we need to highlight a key, refresh it, or leave it
alone, use an if-else chain and inner ifs for activity.
Leverages the new `OneShot.isOneShotKey(key)` and `OneShot.isActive(key)`
methods.
The net result is slightly cleaner code (though it can still be improved), and
about 0.2ms saved, along with some PROGMEM space.

There were a number of issues with the model we had before, namely that plugins
that changed LED colors outside of LED modes had no way to signal "go back to
whatever color this key was". To this end, the `LEDMode.refreshAt` method is
introduced, which these plugins can call to tell the mode to update a given key.
As part of this, the API was redesigned, with code that is common between all
LED modes moving to the base class, among other things, much better names, and a
flow of control that is easier to follow.
In the new setup, there are four methods a LED mode can implement:
- `setup()` to do boot-time initialization (registering hooks, etc).
- `onActivate()` called every time the mode is activated.
- `update()` called each cycle.
- `refreshAt()` may be called by other plugins to refresh a particular key.
All of these are protected methods, to be called via `LEDControl` only.
Much of the new API design was done by @cdisselkoen, huge thanks for his work!

Refactor the momentary layer handling part of `handleKeymapKeyswitchEvent`.

If we have two keys on our keymap that momentarily go to the same layer (which
is the case for the factory firmware), we hold both, and release one, we want
the layer to remain active still.
To this effect, in `handleKeymapKeyswitchEvent` we will handle the case when a
momentary layer key is pressed, but not toggled on (that is, it is held): if it
is not a next/previous switch, we re-activate the layer if it wasn't on.
This fixes#154, thanks to @ToyKeeper for the report.
Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>
With the new implementation, there are two lookup functions, because we have two
caches, and different parts of the firmware will want to use either this or
that (or perhaps both, in rare cases).
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 `effectiveKeymapCache`, 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 or released. (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 `effectiveKeymapCache`
is not useful here. So we use a `keymapCache` 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 `effectiveKeymapCache`-induced
behaviour.
Thus, if we are curious about what a given key will do, use `lookup`. If we
are curious what the active layer state describes the key as, use
`lookupUncached`.
Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>
Only update the keymap cache if the layer state changed for real. If we turn a
layer that was already on, on again, we do not need to update. Same for turning
them off.
This results in a tiny speedup if we have code that calls `Layer.on()` or
`Layer.off()` often.

When we change layers, we want to update the key cache for the whole keyboard,

To find layer keys and layer keys only, we need to make sure that `key.flags`
has only these two bits set, and none of the others. Otherwise it may light up
keys as if they were layer keys, while they aren't, because they happen to have
`SYNTHETIC` and `SWITCH_TO_KEYMAP` set, `RESERVED` unset, but have other flags
that make the event handler loop treat them properly. Mouse keys are one such
thing.

If the `RESERVED` bit is set, that means the key is outside of the control of
the core firmware, and as such, can't be a normal layer key. As it happens,
`OSM(LeftControl)` (and other OSM keys) triggered this branch of code, and
resulted in one-shot modifiers getting highlighted too.

If we do not turn `should_cancel_` off, the next time one taps a one-shot key,
the flag will still be on (because nothing else turned it off, and it was set
before `hold_time_out_` happened, because the normal one-shot timeout is shorter
than that). If the flag is on, the loop hook will turn any and all one-shot
effects off.
In practice, this resulted in one-shot keys not working properly if they were
held for a longer period before.
