I wrote the below code

    pattern = '\\#\\s*include\\s*"(?P<filename>[a-zA-Z0-9\\_\\-\\.\\/]+)"'
    regex = re.compile(pattern)
    includes = []
    def replace(match):
        filename = match.group('filename')
        if (filename not in includes):
            includes.append(filename)
            path = glsl.find(filename)
            if (not path):
                logger.critical(('"%s"    not    found' % filename))
                raise RuntimeError('File    not    found', filename)
            text = ('\n//    ---    start    of    "%s"    ---\n' % filename)
            with open(path) as fh:
                text += fh.read()
            text += ('//    ---    end    of    "%s"    ---\n' % filename)
            return text
        return ''
    for i in range(10):
        if re.search(regex, code):
            code = re.sub(regex, replace, code)
        else:
            break
    return code
