在 vscode 中设置字符 $ 以将文本包装为括号

问题描述

假设存在以下代码.

sample text

当用户双击text，然后按{或(，它只是在保留文本的同时包装文本.

When user double click text, then press { or (, it just wraps the text while keeping it.

sample {text}
sample (text)

但我不知道如何将此规则应用于 VS Code 设置中的 $.我期待的是

But I don't know how to apply this rule to $ in VS Code Settings.What I expect is

sample $text$

VS Code 中的哪些设置与此功能相关?

Which setting in VS Code is related to this feature?

推荐答案

是 vscode 中的设置.但它只适用于引号和括号，如 ()、{}、<>和 [] (可能还有一些其他语言定义的情况).不幸的是，您无法更改该设置以包含另一个字符，例如 $.

is the setting in vscode. But it only applies to quotes and brackets like (), {}, <> and [] (and possibly some other language-defined cases). You cannot change that setting to include another character like $ unfortunately.

这是您可以尝试的键绑定(在 keybindings.json 中):

Here is a keybinding you might try (in keybindings.json):

{
  "key": "alt+4",         // or whatever keybinding you wish
  "command":  "editor.action.insertSnippet",
  "args": {
    //  "snippet": "\\$$TM_SELECTED_TEXT\\$"

       // to have the text still selected after the $'s are inserted, use this
    "snippet": "\\$${1:$TM_SELECTED_TEXT}\\$"
  },
  "when": "editorTextFocus && editorHasSelection"
},

这样，当您选择任何选定的文本时，它都会被 $ 和 +(其中 $ 在英文键盘上).如果您经常进行该操作，那可能是值得的.

So that any selected text will be wrapped by a $ when you select it and + (where the $ is on an English keyboard). If you do that operation a lot it might be worth it.

如果您在上面的代码段中使用这一行:

If you use this line instead in the snippet above:

    "snippet": "$1$TM_SELECTED_TEXT$1"  // or

    "snippet": "$1${2:$TM_SELECTED_TEXT}$1"

然后更一般地选择要环绕的文本，触发该键绑定并键入要环绕选择的任何字符和数量.

then more generically select text to surround, trigger that keybinding and type whichever and how many characters you want to wrap the selection.
