VSCode Extension Developer-tool for VSCode extension development.

Example

Suppose a developer is creating a new extension that requires a custom command. The developer can request a code snippet for registering a command. VSCode Extension Developer will provide a snippet similar to: ```typescript import * as vscode from 'vscode'; export function activate(context: vscode.ExtensionContext) { let disposable = vscode.commands.registerCommand('extension.helloWorld', () => { vscode.window.showInformationMessage('Hello World!'); }); context.subscriptions.push(disposable); } ``` This code snippet registers a command 'extension.helloWorld' that displays 'Hello World!' in an information message.

Scenario

A developer building an extension to automate certain tasks in VSCode could use this function to quickly generate the boilerplate code necessary to implement specific commands, saving time and reducing the likelihood of syntax errors.

Example

When a developer is unsure about the lifecycle events in a VSCode extension, they can inquire about how activation and deactivation work. VSCode Extension Developer will explain that the `activate` function is called when the extension is activated, typically when the first command it contributes is invoked, and the `deactivate` function is called during shutdown. It would provide a detailed explanation along with example code: ```typescript export function deactivate() { // Cleanup resources here } ```

Scenario

This is particularly useful for developers who are new to the VSCode extension ecosystem and need a clear understanding of how and when their code will be executed.

Example

A developer might run into issues where their extension is not behaving as expected. They could ask for help in debugging the extension. VSCode Extension Developer could suggest adding logging statements or using the VSCode built-in debugger to set breakpoints. For example: ```typescript console.log('Extension activated'); ``` It might also guide them on how to configure `launch.json` for debugging the extension.

Scenario

In real-world scenarios, when an extension fails to activate or perform as intended, the developer can quickly get assistance in identifying and resolving issues, ensuring a smoother development process.
