Feature: suppose to vue-tsc supported custom cli options for settings own tsconfig.json path.

[tsukuha]

Thanks for looking my suggest.

Abstract

vue-tsc is a cli tool, so I think good for supported custom cli options for settings own tsconfig.json path.

CLI Example

npx vue-tsc --project ${TS_CONFIG_PATH} ${VUE_FILE_PATH}

Code Example

• packages/tsc/index.ts

import { runTsc } from '@volar/typescript/lib/quickstart/runTsc';
import * as vue from '@vue/language-core';

const windowsPathReg = /\\/g;

function createCliOptions(processArgs: string[]) {
	const args = structuredClone(processArgs);
	const parsedOptions: Record<string, string> = {};
	const ARGS_ACCESS_NUM = 2;
	args.slice(ARGS_ACCESS_NUM).forEach((arg, i) => {
		const options = ['project'];
		const optionStrings = options.map(t => `--${t}`);
		if (!optionStrings.includes(arg)) {
			return;
		}
		if (args[i + 1] == null) {
			return;
		}
		const findIndex = optionStrings.findIndex(s => s === arg);
		if (findIndex !== -1) {
			parsedOptions[options[findIndex]] = args[i + 1];
			// required to remove custom options and value for executing runTsc()
			process.argv = processArgs.filter((_, j) => j !== i + ARGS_ACCESS_NUM && j !== i + ARGS_ACCESS_NUM + 1);
		}
		args.slice(1);
	});
	return parsedOptions;
}

export function run() {
	let runExtensions = ['.vue'];
        // this changed
	const cliOptions = createCliOptions(process.argv);

	const extensionsChangedException = new Error('extensions changed');
	const main = () => runTsc(
		require.resolve('typescript/lib/tsc'),
		runExtensions,
		(ts, options) => {
                        // this changed
			if (cliOptions['project']) {
				options.options.configFilePath = cliOptions['project'];
			}
			const { configFilePath } = options.options;
			const vueOptions = typeof configFilePath === 'string'
				? vue.createParsedCommandLine(ts, ts.sys, configFilePath.replace(windowsPathReg, '/')).vueOptions
				: vue.resolveVueCompilerOptions({});
