vscode-tasks - 有没有办法在 VS Code 任务中动态填充 pickString？

Question

我想提供一个字符串列表作为任务的pickString。字符串列表将是文件夹名称列表，我可以从 PowerShell 获取，但我不确定如何在任务中显示此列表。

如何设置我的任务和输入以便可以填充此列表？

{
  "version": "2.0.0", 
  "tasks": [
    {
      "label": "Test Task", 
      "type":  "shell", 
      "windows": {
        "command":  "echo",
          "args": [
            "-opt",
            "${input:optionsList}"
          ]
      }
    }
  ], 
  "inputs": [
    "id": "optionsList", 
    "type": "pickString", 
    "options": [<insert something here>]
  ]
}

我希望用户在任务运行时查看文件夹列表。

Task/Launch Input Variables显示了一种使用 command input variable 执行此操作的方法.该命令可以来自 vscode 的内置命令或扩展。在您的情况下，没有内置命令可返回给定工作区中的文件夹列表。但是在扩展中执行它是相当简单的。该文档没有给出如何执行此操作的完整示例，因此我将在此处展示一个示例。首先是它的演示到 ls任务中选定的文件夹:
.
这是整个tasks.json文件:

    {
      "version": "2.0.0",
      "tasks": [
    
        {
          "label": "List Folder Choice files",
          "type": "shell",
          "command": "ls",            // your command here
          "args": [
            "${input:pickTestDemo}"  // wait for the input by "id" below
          ],
          "problemMatcher": []
        }
      ],
      
      "inputs": [
        {
          "id": "pickTestDemo",
          "type": "command",
          "command": "folder-operations.getFoldersInWorkspace"  // returns a QuickPick element
        },
      ]
    } 

您可以在输入变量中看到从 folder-operations 调用的命令。延期。由于该命令返回 QuickPick运行任务时将看到的元素。
这是扩展的内容:

    const vscode = require('vscode');
    const fs = require('fs');
    const path = require('path');
    
    /**
     * @param {vscode.ExtensionContext} context
     */
    function activate(context) {
    
        let disposable = vscode.commands.registerCommand('folder-operations.getFoldersInWorkspace', async function () {
    
        // get the workspaceFolder of the current file, check if multiple workspaceFolders
        // a file must be opened
        const wsFolders = await vscode.workspace.workspaceFolders;
        if (!wsFolders)  vscode.window.showErrorMessage('There is no workspacefolder open.')
        const currentWorkSpace = await vscode.workspace.getWorkspaceFolder(vscode.window.activeTextEditor.document.uri);
    
        // filter out files, keep folder names.  Returns an array of string.
        // no attempt made here to handle symbolic links for example - look at lstatSync if necessary
    
        const allFilesFolders = fs.readdirSync(currentWorkSpace.uri.fsPath);
        const onlyFolders = allFilesFolders.filter(f => fs.statSync(path.join(currentWorkSpace.uri.fsPath, f)).isDirectory());
    
        // showQuickPick() takes an array of strings
        return vscode.window.showQuickPick(onlyFolders);
        });
    
        context.subscriptions.push(disposable);
    }
    
    exports.activate = activate;
    
    // this method is called when your extension is deactivated
    function deactivate() {}
    
    module.exports = {
        activate,
        deactivate
    }

这是 folder-operations 的链接演示扩展，因此您可以查看完整的扩展代码及其 package.json。设置好扩展发布凭据后，发布更多内容真的很容易。
