VS Code Vim 速记

https://marketplace.visualstudio.com/items?itemName=vscodevim.vim

VS Code 的 Vim 扩展，除了复现标准的 Vim 键位之外，默认启用了几个插件，在此简单罗列平时常用的几个。

vim-surround

Based on surround.vim, the plugin is used to work with surrounding characters like parentheses, brackets, quotes, and XML tags.

t or < as <desired> or <existing> will enter tag entry mode. Using <CR> instead of > to finish changing a tag will preserve any existing attributes.

Surround Command	Description
y s <motion> <desired>	Add desired surround around text defined by <motion>
d s <existing>	Delete existing surround
c s <existing> <desired>	Change existing surround to desired
S <desired>	Surround when in visual modes (surrounds full selection)

Some examples:

• "test" with cursor inside quotes type cs"' to end up with 'test'

• "test" with cursor inside quotes type ds" to end up with test

• "test" with cursor inside quotes type cs"t and enter 123> to end up with <123>test</123>

vim-commentary

Similar to vim-commentary, but uses the VS Code native Toggle Line Comment and Toggle Block Comment features.

Usage examples:

• gc - toggles line comment. For example gcc to toggle line comment for current line and gc2j to toggle line comments for the current line and the next two lines.

• gC - toggles block comment. For example gCi) to comment out everything within parentheses.

vim-indent-object

Based on vim-indent-object, it allows for treating blocks of code at the current indentation level as text objects. Useful in languages that don't use braces around statements (e.g. Python).

Provided there is a new line between the opening and closing braces / tag, it can be considered an agnostic cib/ci{/ci[/cit.

Command	Description
<operator>ii	This indentation level
<operator>ai	This indentation level and the line above (think if statements in Python)
<operator>aI	This indentation level, the line above, and the line after (think if statements in C/C++/Java/etc)

VSCodeVim tricks!

• gd - jump to definition.

• gq - on a visual selection reflow and wordwrap blocks of text, preserving commenting style. Great for formatting documentation comments.

• gb - adds another cursor on the next word it finds which is the same as the word under the cursor.

• af - visual mode command which selects increasingly large blocks of text. For example, if you had "blah (foo [bar 'ba|z'])" then it would select 'baz' first. If you pressed af again, it'd then select [bar 'baz'], and if you did it a third time it would select "(foo [bar 'baz'])".

• gh - equivalent to hovering your mouse over wherever the cursor is. Handy for seeing types and error messages without reaching for the mouse!
