示例1: colorize

	public static colorize(modeService: IModeService, text: string, mimeType: string, options: IColorizerOptions | null | undefined): Promise<string> {
		let tabSize = 4;
		if (options && typeof options.tabSize === 'number') {
			tabSize = options.tabSize;
		}

		if (strings.startsWithUTF8BOM(text)) {
			text = text.substr(1);
		}
		let lines = text.split(/\r\n|\r|\n/);
		let language = modeService.getModeId(mimeType);
		if (!language) {
			return Promise.resolve(_fakeColorize(lines, tabSize));
		}

		// Send out the event to create the mode
		modeService.triggerMode(language);

		const tokenizationSupport = TokenizationRegistry.get(language);
		if (tokenizationSupport) {
			return _colorize(lines, tabSize, tokenizationSupport);
		}

		const tokenizationSupportPromise = TokenizationRegistry.getPromise(language);
		if (tokenizationSupportPromise) {
			// A tokenizer will be registered soon
			return new Promise<string>((resolve, reject) => {
				tokenizationSupportPromise.then(tokenizationSupport => {
					_colorize(lines, tabSize, tokenizationSupport).then(resolve, reject);
				}, reject);
			});
		}

		return new Promise<string>((resolve, reject) => {
			let listener: IDisposable | null = null;
			let timeout: TimeoutTimer | null = null;

			const execute = () => {
				if (listener) {
					listener.dispose();
					listener = null;
				}
				if (timeout) {
					timeout.dispose();
					timeout = null;
				}
				const tokenizationSupport = TokenizationRegistry.get(language!);
				if (tokenizationSupport) {
					_colorize(lines, tabSize, tokenizationSupport).then(resolve, reject);
					return;
				}
				resolve(_fakeColorize(lines, tabSize));
			};

			// wait 500ms for mode to load, then give up
			timeout = new TimeoutTimer();
			timeout.cancelAndSet(execute, 500);
			listener = TokenizationRegistry.onDidChange((e) => {
				if (e.changedLanguages.indexOf(language!) >= 0) {
					execute();
				}
			});
		});
