续VS Code英汉词典插件v0.0.7-尝试词性搭配, 下一个功能打算实现文件的批量命名翻译: 批量代码汉化工具 · Issue #86 · program-in-chinese/overview

功能仍未完成. 下面仅为效果演示之用. 并未实际调用英汉词典数据:

相关源码

新建编辑器内容提供者:

'use strict';

import * as vscode from 'vscode';

export default class Provider implements vscode.TextDocumentContentProvider{

    static scheme = 'references';
    private _演示字典: Map<String, String> = new Map([
        ["BasicCalculator", "基本的计算器"],
        ["Calculator", "计算器类"],
        ["calculator", "计算器"],
        ["add", "加"],
        ["subtract", "減"],
        ["multiply", "乘"],
        ["divide", "除"],
        ["first", "第一"],
        ["second", "第二"],
        ["number", "数"],
        ["divisor", "被除数"]
    ]);

    dispose() {
    }

    provideTextDocumentContent(uri: vscode.Uri): string | Thenable<string> {
        var 新内容 = vscode.window.activeTextEditor.document.getText();
        for (var 原命名 of this._演示字典.keys()) {
          新内容 = this._replaceAll(新内容, 原命名, this._演示字典.get(原命名));
        }
        return 新内容;
    }

    private _replaceAll(str, find, replace) {
    return str.replace(new RegExp(find, 'g'), replace);
  }
}

let seq = 0;

export function encodeLocation(uri: vscode.Uri, pos: vscode.Position): vscode.Uri {
    const query = JSON.stringify([uri.toString(), pos.line, pos.character]);
    return vscode.Uri.parse(`${Provider.scheme}:test.java?${query}#${seq++}`);
}

添加并列编辑器("状态框"为现有功能):

    const provider = new ContentProvider();

    const providerRegistrations = Disposable.from(
        workspace.registerTextDocumentContentProvider(ContentProvider.scheme, provider)
    );

    const commandRegistration = commands.registerTextEditorCommand('editor.翻译标识符', editor => {
        const uri = encodeLocation(editor.document.uri, editor.selection.active);
        return workspace.openTextDocument(uri).then(doc => window.showTextDocument(doc, editor.viewColumn + 1));
    });

    const 状态框 = window.createStatusBarItem(StatusBarAlignment.Right, 100);
    状态框.command = 'extension.翻译选中文本';
    context.subscriptions.push(
        provider,
        commandRegistration,
        providerRegistrations,
        状态框
    );

发现问题

似乎vscode对中文命名的高亮有些问题:

对比英文命名的高亮:

尴尬的彩蛋:

经VS Code 英汉词典进化效果演示: 翻译文件所有命名 - V2EX指出, "演示字典"部分有个错误: divisor是"除数". 当然, 本身英汉词典数据是正确的(如下). 功能实现之后应该不会有此问题:
