扩展API-任务提供程序-构建任务示例 [英] Extension API - Task Provider - Build Task example

问题描述

我为使用的编程语言构建了扩展，并创建了热键快捷方式，用于使用当前打开的文档的URI调用编译器可执行文件.我想将其转换为扩展程序中的构建任务.我已经用构建任务制作了一个tasks.json文件，该文件可以工作并捕获错误等，但是只有将其放在当前工作空间中后，该文件才能工作.

I've built an extension for a programming language that I use and I've created hotkey shortcuts for calling the compiler executable with the currently open document's URI. I want to convert that to a build task in my extension. I have made a tasks.json file with a build task that works and catches errors and such, but it only works if I put it in the current workspace.

绝对没有在任何地方添加构建任务的示例，并且 API文档用于任务提供程序专门用于Ruby Rakefiles或其他东西.我只是想做一个带有问题匹配器的shell可执行构建任务.谁能给我一个例子吗?

There are absolutely no examples of adding a build task anywhere and the API documentation for task providers is specifically for Ruby Rakefiles or something. I'm just wanting to make a shell executable build task with a problem matcher. Can anyone give me an example of that?

推荐答案

这是最小的 TaskProvider 实现，只需在外壳中运行echo "Hello World":

'use strict';
import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
    var type = "exampleProvider";
    vscode.tasks.registerTaskProvider(type, {
        provideTasks(token?: vscode.CancellationToken) {
            var execution = new vscode.ShellExecution("echo \"Hello World\"");
            var problemMatchers = ["$myProblemMatcher"];
            return [
                new vscode.Task({type: type}, vscode.TaskScope.Workspace,
                    "Build", "myExtension", execution, problemMatchers)
            ];
        },
        resolveTask(task: vscode.Task, token?: vscode.CancellationToken) {
            return task;
        }
    });
}

任务定义(new Task()的第一个参数)需要通过package.json和可以根据需要具有其他属性:

The task definition (first argument for new Task()) needs to be contributed via package.json and can have additional properties if needed:

"contributes": {
    "taskDefinitions": [
        {
            "type": "exampleProvider"
        }
    ]
}

执行 Tasks:Run Task 命令时，应激活带有任务提供程序的扩展:

Extensions with a task provider should activate when the Tasks: Run Task command is executed:

"activationEvents": [
    "onCommand:workbench.action.tasks.runTask"
]

最后，要引用的问题匹配器需要在package.json的contributes.problemMatchers部分中提供.

And finally, the problem matcher(s) you want to reference need to be contributed in the package.json's contributes.problemMatchers section.
