From fd3dc3a997d86be0ab9cdccd0099c4f4c219747a Mon Sep 17 00:00:00 2001 From: Pete Sevander Date: Sat, 14 Aug 2021 07:45:52 +0300 Subject: Fix `combo_disable` (#13988) - Dump key buffer when combos are disabled. - Recursive calls to `dump_key_buffer` need to start dumping the buffer from index i+1 to avoid possible infinite loops. - Handle combo key releases even though combo processing is disabled. --- quantum/process_keycode/process_combo.c | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) (limited to 'quantum') diff --git a/quantum/process_keycode/process_combo.c b/quantum/process_keycode/process_combo.c index b4e698decd..e8661839c7 100644 --- a/quantum/process_keycode/process_combo.c +++ b/quantum/process_keycode/process_combo.c @@ -164,11 +164,15 @@ void clear_combos(void) { } static inline void dump_key_buffer(void) { + /* First call start from 0 index; recursive calls need to start from i+1 index */ + static uint8_t key_buffer_next = 0; + if (key_buffer_size == 0) { return; } - for (uint8_t key_buffer_i = 0; key_buffer_i < key_buffer_size; key_buffer_i++) { + for (uint8_t key_buffer_i = key_buffer_next; key_buffer_i < key_buffer_size; key_buffer_i++) { + key_buffer_next = key_buffer_i + 1; queued_record_t *qrecord = &key_buffer[key_buffer_i]; keyrecord_t *record = &qrecord->record; @@ -189,7 +193,7 @@ static inline void dump_key_buffer(void) { record->event.time = 0; } - key_buffer_size = 0; + key_buffer_next = key_buffer_size = 0; } #define NO_COMBO_KEYS_ARE_DOWN (0 == COMBO_STATE(combo)) @@ -340,9 +344,9 @@ static bool process_single_combo(combo_t *combo, uint16_t keycode, keyrecord_t * return false; } - bool key_is_part_of_combo = !COMBO_DISABLED(combo); + bool key_is_part_of_combo = !COMBO_DISABLED(combo) && is_combo_enabled(); - if (record->event.pressed && !COMBO_DISABLED(combo)) { + if (record->event.pressed && key_is_part_of_combo) { uint16_t time = _get_combo_term(combo_index, combo); if (!COMBO_ACTIVE(combo)) { KEY_STATE_DOWN(combo->state, key_index); @@ -472,10 +476,6 @@ bool process_combo(uint16_t keycode, keyrecord_t *record) { return true; } - if (!is_combo_enabled()) { - return true; - } - #ifdef COMBO_ONLY_FROM_LAYER /* Only check keycodes from one layer. */ keycode = keymap_key_to_keycode(COMBO_ONLY_FROM_LAYER, record->event.key); @@ -550,6 +550,8 @@ void combo_disable(void) { #endif b_combo_enable = false; combo_buffer_read = combo_buffer_write; + clear_combos(); + dump_key_buffer(); } void combo_toggle(void) { -- cgit v1.2.3
