Vim備忘

代碼摺疊

經常使用快捷鍵 ——不必定準確，僅供參考。

• za 打開/關閉在光標下的摺疊
• zA 循環地打開/關閉光標下的摺疊
• zc 關閉 (close) 在光標下的摺疊
  • 摺疊，只摺疊最外層的摺疊
• zC 循環關閉 (Close) 在光標下的全部摺疊
  • 對所在範圍內全部嵌套的摺疊點進行摺疊，包括嵌套的全部摺疊.
• zd 刪除 (delete) 在光標下的摺疊。僅當 ‘foldmethod’ 設爲 「manual」 或 「marker」 時有效。
• zD 循環刪除 (Delete) 光標下的摺疊，即嵌套刪除摺疊。
  • 僅當 ‘foldmethod’ 設爲 「manual」 或 「marker」 時有效。
• zE 除去 (Eliminate) 窗口裏「全部」的摺疊。
  • 僅當 ‘foldmethod’ 設爲 「manual」 或 「marker」 時有效。
• zfap 將光標移到段落內，而後按zfap，就能夠自動對整個段落添加摺疊標籤
• zj 向下移動。到達下一個摺疊的開始處。關閉的摺疊也被計入。
• zk 向上移動到前一折疊的結束處。關閉的摺疊也被
• zm 這將摺疊更多 (M-ore)。你能夠重複 「zr」 和 「zm」 來打開和關閉若干層嵌套的摺疊，否則得一個一個的用zc來摺疊.
• zM 關閉全部摺疊
• zo 打開 (open) 在光標下的摺疊
  • 展開摺疊，只展開最外層的摺疊.
• zO 循環打開 (Open) 光標下的摺疊
  • 對所在範圍內全部嵌套的摺疊點展開，包括嵌套摺疊.
• zr 假定你已經建立了若干摺疊，而如今須要閱覽所有文本。你能夠移到每一個摺疊處，並鍵入」zo」。若要作得更快，能夠用這個命令:zr
• zR 打開全部的摺疊
• 你能夠用 |zn| 命令快速禁止摺疊功能。而後 |zN| 恢復原來的摺疊。|zi| 切換於二者 之間。
• [z 到當前打開的摺疊的開始處。
• ]z 到當前打開的摺疊的末尾處。

Alpha helix     (Hh) :   323 is  43.89%
310  helix       (Gg) :     0 is   0.00%

將 Alpha helix (Hh) : 替換成 Alpha helix :

%s/\s\+([^()]\+)\s\+/ /

關鍵點：括號

2015.5.7

一行變多行，這樣子能夠：1s/; /\r/g

換行符替換成空格：1,$s/\n/ /
