我可以在 VS 代码中为 Powershell 保存带有制表符间距的代码片段,但是当我调用代码片段时,它通过不显示变量的 $ 来一直忽略我的变量。它只会粘贴名称并省略 $

当您选择代码片段时,如何让 VS 代码粘贴到 $ 中?

这是我用于"template"片段的 VS Code JSON 文件

{
    // Place your snippets for powershell here. Each snippet is defined under a snippet name and has a prefix, body and
    // description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
    // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the
    // same ids are connected.
    // Example:
    // "Print to console": {
    //  "prefix": "log",
    //  "body": [
    //      "console.log('$1');",
    //      "$2"
    //  ],
    //  "description": "Log output to console"
    // }

"Template": {
    "prefix": "template",
    "body": [
        "<#",
        ".SYNOPSIS",
        "\t<Overview of script>",
        "",
        ".SYNTAX",
        "\t<Cmdlet-Name> -Parameter <value>",
        "",
        ".DESCRIPTION",
        "\t<Brief description of script>",
        "",
        ".PARAMETER <Parameter_Name>",
        "\t<Brief description of parameter input required. Repeat this attribute if required>",
        "",
        ".INPUTS",
        "\t<Inputs if any, otherwise state None>",
        "",
        ".OUTPUTS",
        "\t<Outputs if any, otherwise state None - example: Log file stored in C:\file.log>",
        "",
        ".EXAMPLE",
        "\t<Example goes here. Repeat this attribute for more than one example>",
        "",
        ".REMARKS",
        "\tVersion:        1.0",
        "#>",
        "",
        "#---------------------------------------------------------[Variables]------------------------------------------------------------",
        "",
        "$var1 = <stuff>",
        "$var2 = <stuff>",
        "",
        "#---------------------------------------------------------[Import Modules]--------------------------------------------------------",
        "",
        "Import-Module <name>",
        "",
        "#-----------------------------------------------------------[Functions]------------------------------------------------------------",
        "",
        "Function <FunctionName> {",
        "\t[CmdletBindinging()]",
        "\tparam(",
        "\t\t[Parameter()]",
        "\t\t[string]$MyOptionalParameter,",
        "",
        "\t\t[Parameter(Mandatory)]",
        "\t\t[int]$MyMandatoryParameter",
        "\t)",
        "",
        "\tTry{",
        "\t\t<code goes here>",
        "\t}",
        "",
        "\tCatch {",
        "\t\tWrite-Host $Error.Exception",
        "\t\t$Error.Exception | Out-File Out-File $env:TEMP\file.log",
        "\t\tBreak",
        "\t}",
        "",
        "\tFinally {",
        "\t\t$time = Get-Date",
        "\t\tcompleted at $time | Out-File $env:TEMP\file.log",
        "\t}",
        "}",
        "",
        "#-----------------------------------------------------------[Execution]------------------------------------------------------------",
        "",
        "<FunctionName>",
    ],
    "description": "test"
}

}

当我调用此代码段将模板粘贴到新的 .ps1 文件中时,它省略了所有 $ 。你如何让那些留下来?

最佳答案

在 Visual Studio 代码片段主体中使用 \\$ 嵌入文字 $

例如,要嵌入 PowerShell 变量 $HOME ,请使用 \\$HOME

注意:从片段解析器的角度来看,转义需要单个 \,但由于片段被定义为 JavaScript 字符串,它们本身使用 \ 作为转义字符,因此需要 \\ 以便将单个 \ 传递给片段解析器。

the docs

作为旁白:

不小心使用 $$ ,有些工作,但它的目的不是逃避,它会导致不同的行为:
$$ 前缀标识符的位置变为制表位,因为 Visual Studio Code 将序列解释如下:

第一个 $ 变成文字[1],但第二个 $ 和后面的标识符被解释为 Visual Studio Code 变量引用;如果该名称的内置变量不存在,则将其用作占位符文本。

[1] 任何后面没有跟有效 Visual Studio Code 占位符名称或变量引用的 $ 都按字面处理。
