按文件名或扩展名过滤片段，例如 .spec.ts 和 .spec.js?

Question

我想添加几个片段以在创建 javascript/typescript 单元测试时使用，但我找不到任何方法将片段的全局范围设置为 *.spec.ts 或 *.spec.js

这可能吗？ In the documentation they say that the scope is bases on the language identifier 但我刚刚看到一种方法可以为那里的每种语言添加另一个扩展。

Answer 1

您可以对片段执行此操作。在你的 keybindings.json:

{
    "key": "shift+alt+2",
    "command": "editor.action.insertSnippet",

    "when": "resourceFilename =~ /\.spec\.[tj]s$/",

    // with the snippet text directly in the keybinding   

    "args": {
      "snippet": "console.log()[=10=]"
    }
},

或此键绑定：

{
  "key": "shift+alt+2",
  "command": "editor.action.insertSnippet",
  "when": "resourceFilename =~ /\.spec\.[tj]s$/",
  "args": {
    "name": "unit tests"
  }
}

在代码片段文件中使用此代码片段：

"unit tests": {
    //  "prefix": "",  // not used here

    "body": [
      "console.log()[=12=]",
    ],

限制代码段范围的关键是这个 when 子句：

"when": "resourceFilename =~ /\.spec\.[tj]s$/",

作为正则表达式，它会查找以 .spec.ts 或 .spec.js 结尾的文件名（请注意，您需要在句点之前进行两次转义）。因此，使用 resourceFileName 并构建一个查看其末尾的正则表达式。

现在您选择的键绑定仅在 *.spec.ts 或 *.spec.js 文件中有效。

见a when clause acting as a regular expression, in keybindings documentation:

key-value when clause operator

There is a key-value pair operator for when clauses. The expression key =~ value treats the right hand side as a regular expression to match against the left hand side. For example, to contribute context menu items for all Docker files, one could use:

"when": "resourceFilename =~ /docker/"

由于这个问题，我找到了这个：resourceExtname with two dots not working
