Terminal 生活
始めに
普段の生活環境(?)であるターミナルの設定アレコレ.
現状は rxvt-unicode-256color をメインで利用中. 驚きの軽さが理由の全てかな.
EAW 対応: ロケールの入れ替え
EAW については
などを参照.
手元の環境では East Asian Ambiguous Char と絵文字の文字幅を強制的に "2" とする 修正ロケールを使っている.
微妙に間違っている気もしないではないが, まあ良いか, 的な.
UNICODE の Box drawing char は "1" にした方が良いかなぁ…
自作合成フォント:
「プログラミング」とか「等幅」とかで検索すると イロイロな合成フォントが見つかりますが, いまいち気にいるフォントが無かったので, 自作することにしました.
- uwabami/isfit-plus: Icon Symbols Font In Terminal plus
- uwabami/fsmrmp: FSMRMP - Patched Font: 'Fantasque Sans Mono' + 'Rounded Mgen+'
現状はとりあえずこれで良しとする感じ.
tmux
以前は GNU screen を使っていたのだけれども, 接続先の環境の多くが UTF-8 をサポートしてくれたので, tmux に移行した.
設定は以下の通り.

obsolete
以下は最近やってないこと.
rxvt-unicode の patch 当て
Obsolete 合成フォントを自作するようになったので最近はここまで凝ったことしてないです.
Debian では configure オプションの変えた urxvt のパッケージが提供されていた.
(256色が使いたいので rxvt-unicode-256color を使っていた).
最近はこれらは dummy になっていて, rxvt-unicode を入れれば良い模様
% apt-cache search rxvt-unicode aterm - dummy transitional package for rxvt-unicode aterm-ml - dummy transitional package for rxvt-unicode rxvt - dummy transitional package for rxvt-unicode rxvt-ml - dummy transitional package for rxvt-unicode rxvt-unicode - RXVT-like terminal emulator with Unicode and 256-color support rxvt-unicode-256color - dummy transitional package for rxvt-unicode rxvt-unicode-lite - dummy transitional package for rxvt-unicode
ただ, フォント表示に関して幾つか気になるところがある. 詳細はrxvt-unicodeのフォントレンダリングを改善する - emonkak's Blog
パッチは以下. これに Debian パッケージをこのパッチを当てて rebuild して使っている.

Obsolete EAW対応としてロケールを入れ替えるようになったので, 最近は patch はあててないです.
tmux EAW 文字幅問題の扱いに多少(?)不満があるので, 以下二つのパッチを当てて rebuild して使っている.
一つ目は pane-border 等、全て ASCII で描くパッチ.
