vim

一个有趣的idea

programming vim through its interface

• vim接口(interfaces)自身就是一个编程语言

• 我们可以组合多种按键以达到难以置信的effect

• 一旦形成肌肉记忆，我们就能以思考的速度来编辑文件！

vim模式

• normal
• insert
• replace
• visual
  • plain
  • line
  • block
• command-line

vim基础

navigation

• w move the cursor foward by one word

• b move the cursor backward by one word

• e move to the end of the word

• 0 move to the begin of the line

• $ move to the end of the line

• ^ move to the first non-empty word of the line

• ctrl-D scroll down

• ctrl-U scroll up

• G move to the end of the buffer

• gg move to the begin of the buffer

• L move the cursor to the lowest line shown on the screen

• M move the cursor to the middle line shown on the screen

• H move the cursor to the highest line shown on the screen

• f+charactor find(and move the cursor on top of it) the first charactor of the line after the cursor

• F+charactor find (and move the cursor on top of it) the first charactor of the line before the cursor

• t/T works same but stop until it finds the charactor

• % jump between pairs like ([],{}, …)

edition

• o open a new line below the cursor
• O open a new line above the cursor
• d + movement key only delete
• c + movement key delete and change

select, copy & paste

• v & motion key select

• V & motion key select lines

• ctrl-V & motion key select rectangle region of text

counts

modifier

• d & i & [ delete things in []

• c & i & [ delete things in [] and change

• d & a & [ delete things in [] (include [])

vim控制命令

:help + key(命令)

查看key或命令的用途(帮助文档)

:qa

退出全部打开的文件

Buffers、Tabs、Windows

buffers又叫打开的文件，在vim中打开的文件与windows没有一对一的对应关系。这样有好处，可以同时看同一个文件的两个不同位置的内容

window

• 打开一个Window :sp

tab

• 打开一个Tab :tabnew
• 在tab间切换 gt
