// Caps Word, activated by pressing both shift keys at the same time.
//
// This library implements "Caps Word", which is like conventional Caps Lock,
// but automatically disables itself at the end of the word. This is useful for
// typing all-caps identifiers like `MOD_MASK_ALT`.
//
// Caps Word is activated by pressing the left and right shift keys at the same
// time. This way you don't need a dedicated key for using Caps Word. I've
// tested that this works as expected with one-shot mods and Space Cadet Shift.
// If your shift keys are mod-taps, activate Caps Word by holding both shift
// mod-tap keys until the tapping term, release them, then begin typing.
//
// For full documentation, see
// https://getreuer.info/posts/keyboards/caps-word

// Call this function from `process_record_user()` to implement Caps Word.
bool process_caps_word(uint16_t keycode, keyrecord_t* record);
// Activates or deactivates Caps Word. For instance activate Caps Word with a
// combo by defining a `COMBO_ACTION` that calls `caps_word_set(true)`:
//
// void process_combo_event(uint16_t combo_index, bool pressed) {
// switch(combo_index) {
// case CAPS_COMBO:
// if (pressed) {
// caps_word_set(true); // Activate Caps Word.
// }
// break;
//
// // Other combos...
// }
// }
void caps_word_set(bool active);
// Returns whether Caps Word is currently active.
bool caps_word_get(void);
// An optional callback that gets called when Caps Word turns on or off. This is
// useful to represent the current Caps Word state, e.g. by setting an LED or
// playing a sound. In your keymap, define
//
// void caps_word_set_user(bool active) {
// if (active) {
// // Do something when Caps Word activates.
// } else {
// // Do something when Caps Word deactivates.
// }
// }
void caps_word_set_user(bool active);
// An optional callback which is called on every key press while Caps Word is
// active. When the key should be shifted (that is, a letter key), the callback
// should call `add_weak_mods(MOD_BIT(KC_LSFT))` to shift the key. The callback
// also determines whether the key should continue Caps Word. Returning true
// continues the current "word", while returning false is "word breaking" and
// deactivates Caps Word. The default callback is
//
// bool caps_word_press_user(uint16_t keycode) {
// switch (keycode) {
// // Keycodes that continue Caps Word, with shift applied.
// case KC_A ... KC_Z:
// add_weak_mods(MOD_BIT(KC_LSFT)); // Apply shift to the next key.
// return true;
//
// // Keycodes that continue Caps Word, without shifting.
// case KC_1 ... KC_0:
// case KC_BSPC:
// case KC_MINS:
// case KC_UNDS:
// return true;
//
// default:
// return false; // Deactivate Caps Word.
// }
// }
//
// To customize, copy the above function into your keymap and add/remove
// keycodes to the above cases.
//
// NOTE: Outside of this callback, you can use `caps_word_set(false)` to
// deactivate Caps Word.
