Swap-Words

English | 中文

简介

开发此插件的初衷是实现 "快速交换算式两边的式子, 而符号留在中间" 的功能, 避免总是需要两次剪切粘贴+后续调整空格的麻烦;

采用了 "交换首尾单词" 的简单逻辑来实现;

使用示例

使用空白字符 (空格,制表符,换行符) 区分单词:

• 选中 a = b 快速交换得 b = a
• 选中 中文 | English 快速交换得 English | 中文

如果文本中只含一个单词, 则交换首尾字符;

• 选中 abc 快速交换得 cba
• 选中 ”中文引号“ 快速交换得 “中文引号”

额外支持一些分隔符, 这些情况下没有空格也能正确区分:

• 选中 13,12,11 快速交换得 11,12,13;

目前支持的分隔符已全部在此列出:

• 常见分隔符: ,, ;, |, ",
• 常见运算符: <, >, =, <=, >=, !=;

使用方式

鼠标:

• 在编辑器中选中文本。
• 右键选择 "SWAP: 交换首尾"

键盘：

• 目前没有设置默认快捷键
• 需要的话可自行添加:

keybindings.json

{
  "key": "ctrl+shift+left",
  "command": "swap-words.swapWords",
  "when": "editorTextFocus && editorHasSelection"
}

TODO

• 后续可能支持括号识别, 把带括号的内容识别为一个整体;
• 未来可能支持不等式变号, 例如 a > b 交换后变为 b < a;

Introduction

This extension was created to quickly swap the two sides of an expression while keeping separators in the middle, so you do not need repeated cut-paste and manual spacing fixes.

It is implemented with a simple "swap head and tail words" strategy.

Examples

Words can be split by whitespace (space, tab, newline):

• Select a = b to get b = a

If the selected text contains only one word, the first and last characters are swapped:

• Select abc to get cba

Additional separators are also supported, so swapping works even without spaces:

• Select 13,12,11 to get 11,12,13

All currently supported separators are listed below:

• Common separators: ,, ;, |, "
• Common operators: <, >, =, <=, >=, !=

Usage

Mouse:

• Select text in the editor.
• Right-click and choose SWAP HEAD & TAIL.

Keyboard:

• No default shortcut is assigned.
• Add one manually if needed:

keybindings.json

{
  "key": "ctrl+shift+left",
  "command": "swap-words.swapWords",
  "when": "editorTextFocus && editorHasSelection"
}

TODO

• Support bracket-aware parsing so bracketed content can be treated as a whole.
• Support inequality inversion in the future, for example a > b becomes b < a after swapping.
