This function can be used to construct custom routing engines that iterate through a list of possible routes, attempting to match an incoming request against each route's compiled regular expression. Each field is converted to a named group, so that when a match is found, the fields can be easily extracted using :py:meth:`re.MatchObject.groupdict`. This function does not support the more flexible templating syntax used in the default router. Only simple paths with bracketed field expressions are recognized. For example:: / /books /books/{isbn} /books/{isbn}/characters /books/{isbn}/characters/{name} Also, note that if the template contains a trailing slash character, it will be stripped in order to normalize the routing logic. Args: template(str): The template to compile. Note that field names are restricted to ASCII a-z, A-Z, and the underscore character.
