VisualStudio 代码任务和变量 [英] VisualStudio Code Tasks and Variables

问题描述

Visual Studio 2010 在创建外部工具以定义初始目录(如 $(ItemDir))时有一个选项，该目录将基于当前处于焦点的文件.我正在尝试在 Visual Studio 代码中做类似的事情，但我找不到等效的环境变量来做同样的事情.任何建议将不胜感激.

Visual studio 2010 had an option when creating external tools to define an initial directory like $(ItemDir) which would be based on the file currently in focus. I am trying to do something similar in visual studio code but I cannot find an equivalent environment variable to do the same thing. Any suggestions would be much appreciated.

推荐答案

只是为了将信息形式化为答案:

Just to formalize the info into an answer:

以下是可用于任务的预定义变量列表:变量参考

Here is a list of predefined variables that can be used in tasks: Variables reference

这里有更多关于在任务中使用变量的信息:变量替换

and here is more info on using variables in tasks : Variable substitution

从上面的最后一个链接来看，这真的很有趣:

And this is really interesting from the last link above:

同样，您可以通过以下方式引用您项目的配置设置在名称前加上 ${config:.

Similarly, you can reference your project's configuration settings by prefixing the name with ${config:.

例如，${config:python.pythonPath} 返回 Python 扩展设置python路径.

For example, ${config:python.pythonPath} returns the Python extension setting pythonPath.

以下是自定义任务配置的示例，其中使用您选择的项目在当前文件上执行 autopep8Python 可执行文件:

Below is an example of a custom task configuration which executes autopep8 on the current file using your project's selected Python executable:

{
        "label": "autopep8 current file",
        "type": "process",
        "command": "${config:python.pythonPath}",
        "args": [
            "-m",
            "autopep8",
            "-i",
            "${file}"
        ]
    }

从第一个链接我们看到您甚至可以将命令(如键绑定和命令面板中使用的那些)合并到您的任务中:

From the first link we see that you can even incorporate commands (like those used in keybindings and the command palette) into your tasks:

设置和命令变量

您可以参考 VS Code 设置和使用以下语法的命令:

You can reference VS Code settings and commands using the following syntax:

${config:Name} - 示例:${config:editor.fontSize}${command:CommandID} - 示例:${command:explorer.newFolder}

${config:Name} - example: ${config:editor.fontSize} ${command:CommandID} - example: ${command:explorer.newFolder}

最后，相关但因为有些人可能最终会在这里搜索这些，所以有一些变量可以在代码片段(但不是任务)中使用.请参阅代码段变量

Finally, related but because some people might end up here searching for these, there are variables that can be used in snippets (but not tasks). See Snippet Variables
