更改活动文件时不生成代码

Question

我正在编写一个 vscode 扩展，它可以根据您选择的语言生成更漂亮的配置。 Javascript 和 JSON。该代码在第一个文档上运行良好，但如果您更改为另一个文件并尝试再次单击按钮生成。代码无法启动。有没有办法检查当前文档是否已经更改谢谢

import * as vscode from "vscode";
import { TextDocument } from "vscode";
import {
    activeEditor
} from "./constants";

var statusBar: vscode.StatusBarItem;

export function activate(context: vscode.ExtensionContext) {
    context.subscriptions.push(
        vscode.commands.registerCommand("prettier-config.prettierConfig", async () => {
            var changedDocument = false;
            const fileType = await vscode.window.showInformationMessage(
                "Which file to generate the Prettier Config for?",
                "Javascript",
                "JSON"
            );
            if (fileType === "Javascript" && changedDocument === false) {
                const javascript = activeEditor.edit(
                    (edit: { insert: (arg0: any, arg1: string) => void }) => {
                        edit.insert(
                            new vscode.Position(0, 0),
                            `module.exports = {\n   singleQuote: true,\n   printWidth: 120,\n   tabWidth: 4,\n   trailingComma: all,\n   endOfLine: auto\n};`,
                        );
                    }
                );
            }
            else if (fileType === "JSON" && changedDocument === false) {
                const json = activeEditor.edit(
                    (edit: { insert: (arg0: any, arg1: string) => void }) => {
                        edit.insert(
                            new vscode.Position(0, 0),
                            `{\n   "singleQuote": true,\n   "printWidth": 120,\n   "tabWidth": 4,\n   "trailingComma": "all",\n   "endOfLine": "auto"\n}`,
                        );
                    }
                );
            }
        })
    );
    statusBar = vscode.window.createStatusBarItem(
        vscode.StatusBarAlignment.Right,
        100,
    );
    statusBar.command = "prettier-config.prettierConfig";
    context.subscriptions.push(statusBar);
    context.subscriptions.push(
        vscode.window.onDidChangeActiveTextEditor(updateStatusBar),
        vscode.window.onDidChangeTextEditorSelection(updateStatusBar),
    );
    updateStatusBar();
}

function updateStatusBar(): void {
    statusBar.text = `$(edit) Prettier Config`;
    statusBar.show();
}

function deactivate() {
    statusBar.dispose();
}

如果您需要活动编辑器，只需通过以下方式获取：

const editor = vscode.window.activeTextEditor;

或使用

vscode.commands.registerTextEditorCommand

它以活动编辑器作为参数。

要获取文档的更改状态，请使用：

editor.document.isDirty

更改活动文件时不生成代码
