DvorakJP とは

DvorakJP とは、 Dvorak 配列での入力を行い易くするために改良されたローマ字入力です。類似のものに AZIK(qwert y配列向け) や ACT(AZIK の Dvorak 配列版) があります。これらは元々 uim に入っています。

uim-skk と DvorakJP を組み合わせようとした時の問題点

uim-skk で DvorakJP を入力しようとすると、以下の問題があります。

そもそも DvorakJP 配列が定義されていない。
DvorakJP 配列定義を用意しても「q」を「onn」として扱えない。
変換候補一覧の選択キーが a, s, d, f, ... で、 Dvorak では選択しにくい。

そもそも DvorakJP 配列が定義されていない

対策: 配列定義を準備する。

DvorakJP 配列定義を用意しても「q」を「onn」として扱えない

DvorakJP の配列を見てみると、「q」の位置に「onn」とあります。
ところが、 SKK では、▽モード中の「q」は、平仮名、片仮名を反転したもので確定、という意味になっています。uim-skk の実装では、ローマ字入力の途中でもこの反転して確定という動作が優先されるため、子音+「q」が子音+「onn」になってくれません¹。

対策: ローマ字入力中の「q」は、SKK 操作の「q」とみなさないようにパッチを当てる。

変換候補一覧の選択キーが a, s, d, f, ... で、 Dvorak では選択しにくい

対策: Dvorak に合わせた、 a, o, u, i, ... を用意する。

対策内容

ファイルひとつと、別のファイルへのパッチ適用を行います。
パス名は、 uim の共通ファイルが /usr/share/uim/ に置かれていると仮定したものです。
ファイル・パッチのいずれも 文字コードは EUC-JP として下さい。

DvorakJP 配列定義ファイル

まずは DvorakJP 配列の定義ファイル。いくつかミスってるところがあった気もするけどそのままアップ。
また、これは "US 配列" 用です。JP 配列の場合は、「ai」「an」(それぞれ2文字目が "'"、";" になっているもの) の変更が必要です。

skk.scm へのパッチ

次に、skk.scm に対するパッチ。
DvorakJP 配列を Anthy などでも使いたければ、そちらも変更する必要がありますが、私は専ら SKK ですのでこれだけ。

なお、これは uim-1.8.6 のファイルに対するパッチですが、uim-1.6.* の頃から hunk 位置の微妙な変更か、手で簡単に修正できる軽微なコンフリクトが発生するのみで、ほぼ同じものが使えています。

今後の課題

と言いつつ、数年間使い続けていて、大体満足しているのでほったらかしにする可能性大。

「ai」「ann(の大文字版)」がJP配列とUS配列で異なっているが、これのうまい扱い方はないか。現状は使っているキーボードに合わせてファイルを差し替えています。1 台の PC に多種類のキーボードを接続する使い方をしませんので。
uim-1.9 以降の対応確認 (カスタマイズ以前にそもそもビルドできてません……)。
変換候補一覧の選択キーが、今度は Dvorak 専用になってしまっている。

同じ問題が uim に元々入っている ACT にもあると思うのですが未確認です。 ↩
