我的可视代码调试扩展不执行我的调试器

Question

我创建了一个Visual Code Debugger扩展，在扩展激活例程中，当我调试示例*.xyz文件时，我可以判断它是激活的，因为它将xyz Debugger activated写入控制台。问题是，我的调试器可执行文件名为debugger.exe(这是一个用C#编写的控制台应用程序(无法执行。

当我关闭*.xyz文件时，我在停用扩展函数中的断点会被击中。这让我相信，在大多数情况下，扩展在一定程度上起作用，但并非完全起作用。

我做错了什么？

这是我的扩展名.ts文件

'use strict';
// The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
import * as vscode from 'vscode';
import { WorkspaceFolder, DebugConfiguration, ProviderResult, CancellationToken } from 'vscode';
import * as Net from 'net';

// this method is called when your extension is activated
// your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {
// Use the console to output diagnostic information (console.log) and errors (console.error)
// This line of code will only be executed once when your extension is activated
console.log('XYZ-Debugger Activated');   
}
// this method is called when your extension is deactivated
export function deactivate() {
console.log('XYZ-Debugger Deactivated');
}

这是我的package.json文件：

您没有在activate中注册您希望VSCode执行的操作。

像这样的东西会做你想做的事：

let factory: XYZDebugAdapterDescriptorFactory
export function activate(context: vscode.ExtensionContext) {
const debugProvider = new XYZDebugConfigProvider();
factory = new XYZDebugAdapterDescriptorFactory();
context.subscriptions.push(
vscode.debug.registerDebugConfigurationProvider(
'xyz', debugProvider
)
);
context.subscriptions.push(
vscode.debug.onDidReceiveDebugSessionCustomEvent(
handleCustomEvent
)
);
context.subscriptions.push(vscode.debug.registerDebugAdapterDescriptorFactory('xyz', factory));
context.subscriptions.push(factory);
}

然后，您需要为配置提供一个适配器。这个将连接到提供端口上的DAP服务器或启动xyz.exe

class XYZDebugConfigProvider implements vscode.DebugConfigurationProvider {
resolveDebugConfiguration(folder: WorkspaceFolder | undefined, config: DebugConfiguration, token?: CancellationToken): ProviderResult<DebugConfiguration> {
const editor = vscode.window.activeTextEditor;
const defaultConfig = vscode.extensions
.getExtension("YOUR EXTENSION NAME HERE")
.packageJSON
.contributes
.debuggers[0]
.initialConfigurations[0];
if (!config.request && editor.document.languageId === 'xyz') {
return defaultConfig;
} else if (!config.request) {
// Not trying to debug xyz?
return undefined;
}
config = {
...defaultConfig,
...config
}
config.execArgs = (config.args || [])
.concat(`-l${config.port}`);
return config;
}
}
class ElpsDebugAdapterDescriptorFactory implements vscode.DebugAdapterDescriptorFactory {
private outputchannel: vscode.OutputChannel
constructor() {
this.outputchannel = vscode.window.createOutputChannel(
'XYZ Debug Log'
);
}
createDebugAdapterDescriptor(session: DebugSession, executable: DebugAdapterExecutable | undefined): ProviderResult<DebugAdapterDescriptor> {
if (session.configuration.type !== "xyz") {
return undefined
}
if (session.configuration.request == "launch") {
const args = [...session.configuration.execArgs, session.configuration.program]
this.outputchannel.appendLine(`Starting XYZ with "${session.configuration.executable}" and args "${args.join(" ")}"`)
const debugee = spawn(session.configuration.executable, args)
debugee.stderr.on('data', (data) => {
this.outputchannel.appendLine(data.toString())
})
debugee.stdout.on('data', (data) => {
this.outputchannel.appendLine(data.toString())
})
debugee.on("close", (data) => {
this.outputchannel.appendLine(`Process closed with status ${data}`)
})
debugee.on("error", (data) => {
this.outputchannel.appendLine(`Error from XYZ: ${data.message}:n${data.stack}`)
})
}
return new vscode.DebugAdapterServer(session.configuration.port)
}
dispose() {}
}

最后，您需要将您可能想要使用的配置的其余部分添加到您的package.json和debuggee中的launch.json中——示例调试器的文档中已经很好地介绍了这一部分https://code.visualstudio.com/api/extension-guides/debugger-extension
