A cleverly organized set of utilities to make JavaScript and TypeScript development easier.

function file(callStackLevel = 0) {
	// Sadly, we cannot use import.meta.url because it will return the file path of THIS script, not the calling script.
	
	const stack = new Error().stack;
	if (!stack) return "INVALID";
	
	const line = stack.split('\n').slice(2 + callStackLevel, 3 + callStackLevel)[0];
	if (line.indexOf("(") === -1) return "INVALID";
	
	const path = /(?<path>[^\(\s]+):[0-9]+:[0-9]+/.exec(line)?.groups?.path || "";
	
	return path.replace("file://", "");
}

function directory(callStackLevel = 0) {
	// Sadly, we cannot use import.meta.url because it will return the file path of THIS script, not the calling script.
	
	const stack = new Error().stack;
