* @file achordion.h
|
|
||||||
* @brief Achordion: Customizing the tap-hold decision.
|
|
||||||
*
|
|
||||||
* Overview
|
|
||||||
* --------
|
|
||||||
*
|
|
||||||
* This library customizes when tap-hold keys are considered held vs. tapped
|
|
||||||
* based on the next pressed key, like Manna Harbour's Bilateral Combinations or
|
|
||||||
* ZMK's positional hold. The library works on top of QMK's existing tap-hold
|
|
||||||
* implementation. You define mod-tap and layer-tap keys as usual and use
|
|
||||||
* Achordion to fine-tune the behavior.
|
|
||||||
*
|
|
||||||
* When QMK settles a tap-hold key as held, Achordion intercepts the event.
|
|
||||||
* Achordion then revises the event as a tap or passes it along as a hold:
|
|
||||||
*
|
|
||||||
* * Chord condition: On the next key press, a customizable `achordion_chord()`
|
|
||||||
* function is called, which takes the tap-hold key and the next key pressed
|
|
||||||
* as args. When the function returns true, the tap-hold key is settled as
|
|
||||||
* held, and otherwise as tapped.
|
|
||||||
*
|
|
||||||
* * Timeout: If no other key press occurs within a timeout, the tap-hold key
|
|
||||||
* is settled as held. This is customizable with `achordion_timeout()`.
|
|
||||||
*
|
|
||||||
* Achordion only changes the behavior when QMK considered the key held. It
|
|
||||||
* changes some would-be holds to taps, but no taps to holds.
|
|
||||||
*
|
|
||||||
* @note Some QMK features handle events before the point where Achordion can
|
|
||||||
* intercept them, particularly: Combos, Key Lock, and Dynamic Macros. It's
|
|
||||||
* still possible to use these features and Achordion in your keymap, but beware
|
|
||||||
* they might behave poorly when used simultaneously with tap-hold keys.
|
|
||||||
*
|
|
||||||
*
|
|
||||||
* For full documentation, see
|
|
||||||
* <https://getreuer.info/posts/keyboards/achordion>
