如何从代码段变量$ {TM_FILENAME}中删除扩展名？

Question

我使用vscode。

我想使用costum代码段，但{TM_FILENAME}有一个扩展名。

如何从{TM_FILENAME}删除扩展程序？

像这样：“

在文件MyModule.js中：

转换：${TM_FILENAME/(\w+)\.js/\1/g}

输出：

MyModule

Answer 1

如果知道文件扩展名，则可以尝试这样的操作

${TM_FILENAME/(.js)//}

它将FileName.js转换为FileName

Answer 2

您可以使用TM_FILENAME_BASE仅获取文件名：

${TM_FILENAME_BASE}

Answer 3

实际上，由于提出了问题，所以添加了一些新的内置变量，  包括TM_FILENAME_BASE。参见snippet variables documentation。因此，无需进行转换即可获取不带扩展名的文件名。这是当前的变量列表：

    TM_SELECTED_TEXT      The currently selected text or the empty string
    TM_CURRENT_LINE       The contents of the current line
    TM_CURRENT_WORD       The contents of the word under cursor or the empty string
    TM_LINE_INDEX         The zero-index based line number
    TM_LINE_NUMBER        The one-index based line number
    TM_FILENAME           The filename of the current document
    TM_FILENAME_BASE      The filename of the current document without its extensions
    TM_DIRECTORY          The directory of the current document
    TM_FILEPATH           The full file path of the current document
    CLIPBOARD             The contents of your clipboard
    WORKSPACE_NAME        The name of the opened workspace or folder

    CURRENT_YEAR            The current year
    CURRENT_YEAR_SHORT      The current year's last two digits
    CURRENT_MONTH           The month as two digits (example '02')
    CURRENT_MONTH_NAME      The full name of the month (example 'July')
    CURRENT_MONTH_NAME_SHORT   The short name of the month (example 'Jul')
    CURRENT_DATE            The day of the month
    CURRENT_DAY_NAME        The name of day (example 'Monday')
    CURRENT_DAY_NAME_SHORT  The short name of the day (example 'Mon')
    CURRENT_HOUR            The current hour in 24-hour clock format
    CURRENT_MINUTE          The current minute
    CURRENT_SECOND          The current second

For inserting line or block comments, honoring the current language:

    BLOCK_COMMENT_START      Example output: in PHP /* or in HTML <!--
    BLOCK_COMMENT_END        Example output: in PHP */ or in HTML -->
    LINE_COMMENT             Example output: in PHP // or in HTML <!-- -->

The snippet below inserts /* Hello World */ in JavaScript files and <!-- Hello World --> in HTML files:

{
  "hello": {
      "scope": "javascript,html",
      "prefix": "hello",
      "body": "$BLOCK_COMMENT_START Hello World $BLOCK_COMMENT_END"
  }
}

目前您无法执行此操作，但在vscode GitHub页面上有一个功能请求，可以满足您的需求：https://github.com/Microsoft/vscode/issues/6920。
