Custom QMK Library for international layouts.

This library is designed to provide support for international layouts in QMK. Currently Cyrillic ЙЦУКЕН with Mac and PC layouts are supported only, but feel free to ask for another layouts or implement yours in MRs.

This library supports the following features:

• Cyrillic ЙЦУКЕН keycodes (both WIN and MAC symbol layouts), typing them is based on standard unicode mechanisms in QMK
• Every keycode is independent from input sources in your OS and other layouts. In other words, you may use DVORAK for English layer (and shortcuts) and ЙЦУКЕН (or any other configuration) for Russian layer.
• Shift support. E.g. tapping CYR_YA will produce 0x044F unicode symbol (which is я), tapping shift + CYR_YA will produce 0x042F (which is Я)
• Other modifiers support for shortcuts. E.g. tapping ctrl + alt + CYR_YA will find a keycode in underlying layer and will send it to system (e.g. with ЙЦУКЕН + QWERTY layouts that would be interpreted as ctrl + alt + z)
• One-shot mods support, both shifts and other modifiers
• Weak mods support, both shifts and other modifiers
• Caps word support
• Combo support
• Easy installation and usage (can't make it easier than that)
• NO LT() and MT() support. That's kinda tricky to implement. If you need it, please leave your vote in corresponding issue on github
• Ask for your features and layout support in issues on github

1. Enable unicode support in your QMK firmware. Usually you need to add UNICODE_ENABLE = yes to your rules.mk file. See QMK Unicode Official Documentation for more information.

2. Clone sm_layouts.h and sm_layouts_keycodes.h into your QMK keymap directory (next to your keymap.c file)

3. Edit your config.h

   3.1. Enable desired layouts (see "List of available layouts and keycodes" below). You can enable several layouts, for example:

   #define SM_LAYOUTS_CYR_ENABLED
   #define SM_LAYOUTS_CYR_WIN_SYMBOLS_ENABLED

   3.2. (Optional) Specify shortcut layer. By default, it's 0 (base layer). You can change it by adding #define SM_LAYOUTS_SHORTCUT_LAYER 5 (5 — your desired shortcut layer index) to your config.h file.

4. Edit your keymap.c

   4.1. Add #include "sm_layouts_keycodes.h" and #include "sm_layouts.h" at the top. It's important to include sm_layouts_keycodes.h first.

   4.2. Add if (!process_sm_layouts(keycode, record)) return false; in the beginning of your process_record_user function. It should look like this:

   bool process_record_user(uint16_t keycode, keyrecord_t *record) {
     if (!process_sm_layouts(keycode, record)) return false;
   
     // Rest of your code here
     return true;
   }

   4.3. Add SM_LAYOUTS_KEYCODES to your keymap's enum custom_keycodes list. It should look like this:

   enum custom_keycodes {
     YOUR_CODE_1 = SAFE_RANGE,
     YOUR_CODE_2,
     // Rest of your custom keycodes here
   
     SM_LAYOUTS_KEYCODES,
   };

   If you didn't have added any custom keycodes before, you need to create one with explicit beginning. It should look like this:

   enum custom_keycodes {
     CUSTOM_KEYCODES_BEGIN = SAFE_RANGE,
     SM_LAYOUTS_KEYCODES,
   };

   Please note that you can put SM_LAYOUTS_KEYCODES anywhere except the beginning of the enum. It's important to explicitly define the beginning of your custom keycodes range with SAFE_RANGE.

   4.4 Once you have SM_LAYOUTS_KEYCODES in your enum custom_keycodes, you can add extra keycodes to your keymap PROGMEM keymaps. List of available keycodes depends options you have enabled in config.h. See "List of available layouts and keycodes" below for more information. Also check "Copy-paste keymaps", there are typical keyboard layouts, so you can just copy and paste them.

To enable this keycodes add #define SM_LAYOUTS_CYR_ENABLED to your config.h file. This will give you the following keycodes:

• CYR_A — а or А (shifted)
• CYR_B — б or Б (shifted)
• CYR_V — в or В (shifted)
• CYR_G — г or Г (shifted)
• CYR_D — д or Д (shifted)
• CYR_E — е or Е (shifted)
• CYR_YO — ё or Ё (shifted)
• CYR_ZH — ж or Ж (shifted)
• CYR_ZZ — з or З (shifted)
• CYR_I — и or И (shifted)
• CYR_YY — й or Й (shifted)
• CYR_K — к or К (shifted)
• CYR_L — л or Л (shifted)
• CYR_M — м or М (shifted)
• CYR_N — н or Н (shifted)
• CYR_O — о or О (shifted)
• CYR_P — п or П (shifted)
• CYR_R — р or Р (shifted)
• CYR_SS — с or С (shifted)
• CYR_T — т or Т (shifted)
• CYR_U — у or У (shifted)
• CYR_F — ф or Ф (shifted)
• CYR_H — х or Х (shifted)
• CYR_CC — ц or Ц (shifted)
• CYR_CH — ч or Ч (shifted)
• CYR_SH — ш or Ш (shifted)
• CYR_SCH — щ or Щ (shifted)
• CYR_SLD — ъ or Ъ (shifted)
• CYR_YI — ы or Ы (shifted)
• CYR_SFT — ь or Ь (shifted)
• CYR_YE — э or Э (shifted)
• CYR_YU — ю or Ю (shifted)
• CYR_YA — я or Я (shifted)

To enable this keycodes add #define SM_LAYOUTS_CYR_WIN_SYMBOLS_ENABLED to your config.h file. This will give you the following keycodes:

• CYR_W1 — 1 or ! (shifted)
• CYR_W2 — 2 or " (shifted)
• CYR_W3 — 3 or № (shifted)
• CYR_W4 — 4 or ; (shifted)
• CYR_W5 — 5 or % (shifted)
• CYR_W6 — 6 or : (shifted)
• CYR_W7 — 7 or ? (shifted)
• CYR_W8 — 8 or * (shifted)
• CYR_W9 — 9 or ( (shifted)
• CYR_W0 — 0 or ) (shifted)
• CYR_WDOT — . or , (shifted)
• CYR_WSLASH — \ or / (shifted)

To enable this keycodes add #define SM_LAYOUTS_CYR_MAC_SYMBOLS_ENABLED to your config.h file. This will give you the following keycodes:

• CYR_M1 — 1 or ! (shifted)
• CYR_M2 — 2 or " (shifted)
• CYR_M3 — 3 or № (shifted)
• CYR_M4 — 4 or % (shifted)
• CYR_M5 — 5 or : (shifted)
• CYR_M6 — 6 or , (shifted)
• CYR_M7 — 7 or . (shifted)
• CYR_M8 — 8 or ; (shifted)
• CYR_M9 — 9 or ( (shifted)
• CYR_M0 — 0 or ) (shifted)
• CYR_MSLASH — / or ? (shifted)
• CYR_MBRC — [ or ] (shifted)

Please note that CYR_SLD and CYR_YO don't have a free key in 3x6, so I moved them a bit. You can change it to your needs.

Normally QMK sends R_OPT + unicode for macOS. It's not very convenient due to many applications have R_OPT + Number or R_OPT + A/B/C/D/E/F shortcuts. MacOS also accepts unicode symbols with R_OPT + R_SHIFT + unicode combination. To make it work you will need to patch unicode.c or process_unicode.c (depends on firmware version) file in QMK yourself.

1. Open quantum/process_keycode/process_unicode.c and quantum/unicode/unicode.c (if you have it in your QMK directory).
2. Replace register_code(UNICODE_KEY_MAC); with

   register_code(KC_LEFT_ALT);
   register_code(KC_LEFT_SHIFT);

3. Replace every unregister_code(UNICODE_KEY_MAC); with

   unregister_code(KC_LEFT_SHIFT);
   unregister_code(KC_LEFT_ALT);

4. Rebuild your firmware and flash it to your keyboard.

Go to page chrome://extensions/shortcuts and update shortcuts for your extensions. There is an option Focus on inactive dialogs that uses ALT + SHIFT + A shortcut. You'd better change it to another one. Otherwise, you will have a conflict with R_ALT + R_SHIFT + A unicode combination.

Please check your applications shortcuts and update them if needed. In my cases I had to review shortcuts for JetBrains IDEs, iTerm2, and VSCode.
