epaew's Enhanced Dvorak layout for Japanese Programmer

Layout overview

This is a sample. You can swap any symbol keys and modifier keys.

Base layer (for ansi layout)

  //+----+----+----+----+----+----+----+----+----+----+----+----+----+---------+
      `  , !  , @  , #  , $  , %  , ^  , &  , *  , (  , )  , [  , ]  ,  BSPC   ,
  //+----+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+-------+
      TAB  , '  , ,  , .  , P  , Y  , F  , G  , R  , W  , Q  , /  , =  ,   \   ,
  //+------++---++---++---++---++---++---++---++---++---++---++---++---+-------+
      CAPS  , A  , O  , E  , I  , U  , D  , T  , N  , S  , M  , -  ,    ENT    ,
  //+-------+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-----------+
       LSFT   , ;  , X  , C  , V  , Z  , B  , H  , J  , K  , L  ,     RSFT     ,
  //+------+--+---++----++---+----+----+----+----+-+--+---++----++------+------+
      LCTL , LGUI , LALT ,          SPACE          , RALT , RGUI , MENU , RCTL
  //+------+------+------+-------------------------+------+------+------+------+

Base layer (for iso layout)
- Two C keys are placed, it's on purpose.

  //+----+----+----+----+----+----+----+----+----+----+----+----+----+---------+
      `  , !  , @  , #  , $  , %  , ^  , &  , *  , (  , )  , [  , ]  ,  BSPC   ,
  //+----+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+-------+
      TAB  , '  , ,  , .  , P  , Y  , F  , G  , R  , W  , C  , /  , =  ,
  //+------++---++---++---++---++---++---++---++---++---++---++---++---++
      CAPS  , A  , O  , E  , I  , U  , D  , T  , N  , S  , M  , ;  , -  , ENT  ,
  //+-------+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+------+
       LSFT   , Q  , X  , C  , V  , Z  , B  , H  , J  , K  , L  , \  ,  RSFT   ,
  //+------+--+---++----++---+----+----+----+----+-+--+---++----++---+--+------+
      LCTL , LGUI , LALT ,          SPACE          , RALT , RGUI , MENU , RCTL
  //+------+------+------+-------------------------+------+------+------+------+

Additional layer (common, blanks are transparent)

  //+----+----+----+----+----+----+----+----+----+----+----+----+----+---------+
         ,    ,    ,    ,    ,    ,    ,    ,    ,    ,    ,    ,    ,         ,
  //+----+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+-------+
           , AI , OU , EI ,    ,    ,    ,    ,    ,    ,    ,    ,    ,       ,
  //+------++---++---++---++---++---++---++---++---++---++---++---++---+-------+
            , A  , O  , E  , I  , U  ,    , Y1 , N  , Y2 ,    ,    ,           ,
  //+-------+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-----------+
              ,ANN ,ONN ,ENN ,INN ,UNN ,    ,    ,    ,    ,    ,              ,
  //+------+--+---++----++---+----+----+----+----+-+--+---++----++------+------+
           ,      ,      ,                         ,      ,      ,      ,
  //+------+------+------+-------------------------+------+------+------+------+

And you can see my iris keyboard layout for sample implementation, too.

for Japanese

日本語入力用のキーを追加
- IME 切り替えキー
  - 長押しでレイヤー切り替え、短押しでIME切り替え
  - macOS(かな/英数)、Windows(Alt+`)の両方に対応
- DvorakJP(http://www7.plala.or.jp/dvorakjp/)を参考にした日本語入力用キーの導入
  - 拗音入力用のYキーを追加配置
  - 二重母音入力用のキー(AI, OU, EI)
  - 撥音入力用のキー(ANN, ONN, ENN, INN, UNN)
  - いずれかの子音を押下することで Additional layer が出現し、いずれかの母音を押下することで Base layer に戻ります（※1※2）
    - ※1促音の入力に使うため、また連続で同じ指での打鍵を減らすために、
      FGRDTNBHJ を押下した場合はy1が、それ以外の子音を押下した場合はy2が出現しません
    - ※2撥音の入力のため、nを2連打すると、Base layerに戻ります
Define some custom keys for typing Japanese
- IME switching
  - act as LOWER/RAISE when hold, act as IME switching when tapped
  - for macOS(かな/英数), for Windows(Alt+`)
- oneshot combination keys, inspired from DvorakJP (http://www7.plala.or.jp/dvorakjp/)
  - additional Y key to enter a contracted sound
  - diphthong keys (AI, OU, EI)
  - syllabic nasal (ANN, ONN, ENN, INN, UNN)
  - Additional layer is appeared when you taps any consonant keys, and disappeared when you taps any diphthong keys.

for Programmer

Dvorak 配列をベースに、ショートカットでよく利用される XCV は QWERTY 配列の位置を維持
Vimユーザのために、HJKL キーを横並びで配置
デフォルトレイヤーには、数字キーの代わりに記号 !@#$%^&*() を配置
mainly based on Dvorak layout, but XCV is available in the same position of QWERTY layout
HJKL is lining side by side, for Vim users
we can type !@#$%^&*() keys without shift keys in base layer
