* keycode_string(): Format keycodes as strings. This adds the `keycode_string()` function described in https://getreuer.info/posts/keyboards/keycode-string/index.html as a core feature. * Fix formatting. * keycode_string review revisions. * Rename keycode_string() -> get_keycode_string() for consistency with existing string utils like get_u8_str(). * Revise custom keycode names with separate _user and _kb tables. * Correct indent in builddefs/generic_features.mk. Co-authored-by: Ryan * Add KC_NUHS, KC_NUBS, and KC_CAPS. * Fix linking error with custom names. * Attempt at simplifying interface. * Formatting fix. * Several fixes and revisions. * Don't use PSTR in KEYCODE_STRING_NAME, since this fails to build on AVR. Store custom names in RAM. * Revise the internal table of common keycode names to use its own storage representation, still in PROGMEM, and now more efficiently stored flat in 8 bytes per entry. * Support Swap Hands keycodes and a few other keycodes. * Revert "Formatting fix." This reverts commit 2a2771068c7ee545ffac4103aa07e847a9ec3816. * Revert "Attempt at simplifying interface." This reverts commit 8eaf67de76e75bc92d106a8b0decc893fbc65fa5. * Simplify custom names API by sigprof's suggestion. * Support more keycodes. * Add QK_LOCK keycode. * Add Secure keycodes. * Add Joystick keycodes. * Add Programmable Button keycodes. * Add macro MC_ keycodes. * For remaining keys in known code ranges, stringify them as "QK_+". For instance, "QK_MIDI+7". * Bug fix and a few improvements. * Fix missing right-hand bit when displaying 5-bit mods numerically. * Support KC_HYPR, KC_MEH, HYPR_T(kc), MEH_T(kc). * Exclude one-shot keycodes when NO_ACTION_ONESHOT is defined. --------- Co-authored-by: Ryan
