使用微软Monaco Editor 编写代码比对工具
前言
微软之前有个项目叫做Monaco Workbench，后来这个项目变成了VS Code，而Monaco Editor就是从这个项目中成长出来的一个web编辑器，所以Monaco Editor和VS Code在编辑代码，交互以及UI上几乎是一摸一样的，有点不同的是，两者的平台不一样，Monaco Editor基于浏览器，而VS Code基于electron，所以功能上VSCode更加健全，并且性能比较强大。本文主要介绍ng-zorro 框架集成Monaco Editor实现文本比对。Monaco Editor 不仅能做文本比对，同样可以做代码编辑器，可以查阅《使用微软Monaco Editor 编写在线调试工具》。
环境及组件
Monaco Editor 微软 Monaco Editor 编辑器
Ant Design of Angular NG-ZORRO
ngx-monaco-editor monaco-editor angular npm 包
实现
根据 ngx-monaco-editor 文档按angular版本安装指定版本的npm包
注意：版本对应不上会导致资源404错误
- Angular <= 4: v3.x.x
- Angular 5: v5.x.x
- Angular 6: v6.x.x
- Angular 7: v7.x.x
- Angular 8: v8.x.x
- Angular 9: v9.x.x
npm install [email protected] --save
接下来配置全局静态资源
Angular 6 之前版本 添加到.angular-cli.json文件中
{
"options": {
{
"assets": [
{
"glob": "**/*", "input": "node_modules/ngx-monaco-editor/assets/monaco", "output": "./assets/monaco/" }
],
...
}
...
},
...
}
Angular 6 之后版本 添加到.angular.json文件中
{
"apps": [
{
"assets": [
{
"glob": "**/*", "input": "../node_modules/ngx-monaco-editor/assets/monaco", "output": "./assets/monaco/" }
],
...
}
...
],
...
}
Angular 模块文件中配置 DiffEditorModule
import {
NgModule } from '@angular/core';
import {
DiffEditorRoutingModule } from './diff-editor-routing.module';
import {
DiffEditorComponent } from './diff-editor.component';
import {
NgZorroAntdModule } from 'ng-zorro-antd';
import {
CommonModule } from '@angular/common';
import {
ClipboardModule } from 'ngx-clipboard';
import {
FormsModule } from '@angular/forms';
import {
MonacoEditorModule } from 'ngx-monaco-editor';
@NgModule({
imports: [
CommonModule,
DiffEditorRoutingModule,
NgZorroAntdModule,
ClipboardModule,
FormsModule,
MonacoEditorModule.forRoot(),
],
declarations: [DiffEditorComponent],
exports: [DiffEditorComponent]
})
export class DiffEditorModule {
}
Monaco Editor 支持选择文本语言、编辑器主题等等配置，我们同样在页面上也支持这些配置项动态配置，结合阿里的NG-ZORRO框架，完整代码如下：
<div nz-row [nzGutter]="16">
<div nz-col class="gutter-row" [nzSpan]="24" *ngIf="isCompared">
<nz-select [(ngModel)]="selectedLang" class="lang-select ditor-config" (ngModelChange)="onChangeLanguage($event)">
<nz-option *ngFor="let option of languages" [nzValue]="option" [nzLabel]="option">nz-option>
nz-select>
<nz-select [(ngModel)]="selectedTheme" class="lang-select ditor-config" (ngModelChange)="onChangeTheme($event)">

nz-select>
<nz-switch class="ditor-config" [(ngModel)]="switchValue" [nzControl]="true" (click)="onChangeInline()" nzCheckedChildren="开启内联差异"
nzUnCheckedChildren="关闭内联差异">nz-switch>

<div nz-col class="gutter-row diff-editor-row" [nzSpan]="24" *ngIf="isCompared">

<div nz-col class="gutter-row" [nzSpan]="24" *ngIf="!isCompared">
<button class="ditor-config" nz-button nzType="primary" (click)="onCompare()">比对文本button>
div>
<div nz-col class="gutter-row" [nzSpan]="12" *ngIf="!isCompared">
<textarea nz-input placeholder="请输入比对文本" [nzAutosize]="{ minRows: 10, maxRows: 29 }" [(ngModel)]="text1">textarea>

运行结果如下：
完美运行
