Agda ではUnicodeな括弧を良く使うわけなんだけど、show match して欲しいよね?
( [ { ⁅ ⁽ ₍ 〈 ⎴ ⟅ ⟦ ⟨ ⟪ ⦃ 〈 《 「 『 【 〔 〖 〚 ︵ ︷ ︹ ︻ ︽ ︿ ﹁ ﹃ ﹙ ﹛ ﹝ ( [ { 「
) ] } ⁆ ⁾ ₎ 〉 ⎵ ⟆ ⟧ ⟩ ⟫ ⦄ 〉 》 」 』 】 〕 〗 〛 ︶ ︸ ︺ ︼ ︾ ﹀ ﹂ ﹄ ﹚ ﹜ ﹞ ) ] } 」
このあたり。evil.el は dot (command の repeat ) が馬鹿過ぎて諦めました。たぶん、agda-mode との干渉もあるんでしょう。
結論的には以下のコードを ~/.emacs.d/init.el に入れればよい。まぁ、少し動作はおかしいが、良しとする。
(space は全角間隔にしてるのでコピペでは動きません)
