extesion.ts 함수입니다.
계속 Hello World 만 쳐야 하는게 싫어서 Hi 로 바꿔봤습니다.

// The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
import { window, commands, Disposable, ExtensionContext, StatusBarAlignment, StatusBarItem, TextDocument } from 'vscode';

// This method is called when your extension is activated. Activation is
// controlled by the activation events defined in package.json.
export function activate(context: 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('Congratulations, your extension "WordCount" is now active!');

    // create a new word counter
    let wordCounter = new WordCounter();

    // sayHello 를 sayHi 함수로 변경
    let disposable = commands.registerCommand('extension.sayHi', () => {
        wordCounter.updateWordCount();
    });

    // Add to a list of disposables which are disposed when this extension is deactivated.
    context.subscriptions.push(wordCounter);
    context.subscriptions.push(disposable);
}

class WordCounter {

    private _statusBarItem: StatusBarItem =  window.createStatusBarItem(StatusBarAlignment.Left);

    public updateWordCount() {

        // Get the current text editor
        let editor = window.activeTextEditor;
        if (!editor) {
            this._statusBarItem.hide();
            return;
        }

        let doc = editor.document;

        // Only update status if a Markdown file
        // markdown 체크
        if (doc.languageId === "markdown") {
            let wordCount = this._getWordCount(doc);

            // Update the status bar
            this._statusBarItem.text = wordCount !== 1 ? `${wordCount} Words` : '1 Word';
            this._statusBarItem.show();
        } else {
            this._statusBarItem.hide();
        }
    }

    public _getWordCount(doc: TextDocument): number {

        let docContent = doc.getText();

        // Parse out unwanted whitespace so the split is accurate
        docContent = docContent.replace(/(< ([^>]+)<)/g, '').replace(/\s+/g, ' ');
        docContent = docContent.replace(/^\s\s*/, '').replace(/\s\s*$/, '');
        let wordCount = 0;
        if (docContent !== "") {
            wordCount = docContent.split(" ").length;
        }

        return wordCount;
    }

    dispose() {
        this._statusBarItem.dispose();
    }
}

JSON 파일도 수정해줍니다.

JSON 은 주석이 안되서 사진만 빠르게..

이제 HI 라고 쳐도 반응을 합니다 !

아래에 3단어라고 표시됩니다.

Hi 라고 호출해야지 Words 가 표시되는데

자동으로 쭉 ~ 표시되는 방법은 다음편에 계속하겠습니다.
