From 7e983796e18e7401c062c158f23966aeb7b1405b Mon Sep 17 00:00:00 2001 From: Pete Sevander Date: Fri, 6 Aug 2021 02:44:57 +0300 Subject: Process combos earlier & overlapping combos (#8591) * Combo processing improvements. Now it is possible to use ModTap and LayerTap keys as part of combos. Overlapping combos also don't trigger all the combos, just exactly the one that you press. New settings: - COMBO_MUST_HOLD_MODS - COMBO_MOD_TERM - COMBO_TERM_PER_COMBO - COMBO_MUST_HOLD_PER_COMBO - COMBO_STRICT_TIMER - COMBO_NO_TIMER * Remove the size flags from combo_t struct boolean members. This in the end actually saves space as the members are accessed so many times. The amount of operations needed to access the bits uses more memory than setting the size saves. * Fix `process_combo_key_release` not called correctly with tap-only combos * Fix not passing a pointer when NO_ACTION_TAPPING is defined. * Docs for `COMBO_ONLY_FROM_LAYER` * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update quantum/process_keycode/process_combo.c Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Add `EXTRA_SHORT_COMBOS` option. Stuff combo's `disabled` and `active` flags into `state`. Possibly can save some space. * Add more examples and clarify things with dict management system. - Simple examples now has a combo that has modifiers included. - The slightly more advanced examples now are actually more advanced instead of just `tap_code16()`. - Added a note that `COMBO_ACTION`s are not needed anymore as you can just use custom keycodes. - Added a note that the `g/keymap_combo.h` macros use the `process_combo_event` function and that it is not usable in one's keymap afterwards. * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Change "the" combo action example to "email" example. * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Fix sneaky infinite loop with `combo_disable()` No need to call `dump_key_buffer` when disabling combos because the buffer is either being dumped if a combo-key was pressed, or the buffer is empty if a non-combo-key is pressed. * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> Co-authored-by: Drashna Jaelre --- quantum/keymap_common.c | 3 + quantum/process_keycode/process_combo.c | 548 ++++++++++++++++++++++++++------ quantum/process_keycode/process_combo.h | 36 ++- quantum/quantum.c | 23 +- 4 files changed, 498 insertions(+), 112 deletions(-) (limited to 'quantum') diff --git a/quantum/keymap_common.c b/quantum/keymap_common.c index e0fd6d4793..780c71ab9b 100644 --- a/quantum/keymap_common.c +++ b/quantum/keymap_common.c @@ -40,7 +40,10 @@ extern keymap_config_t keymap_config;
