Regex Editor & Tester

This regex matches an API annotation block that begins with ##api followed by arbitrary content, then a marker ##, and later a function definition line in Russian where 'Функция' (meaning 'Function') precedes the function name and its parenthesized parameters. It captures the API description (apicont), the function name (funcname), and the parameter list (funcparam). Useful for extracting structured API documentation from source code or markdown-like comments with a specific format.
