from flask import Flask
from werkzeug.routing import BaseConverter

app = Flask(__name__)

class RegexConverter(BaseConverter):
    def __init__(self, url_map, *items):
        super(RegexConverter, self).__init__(url_map)
        self.regex = items[0]


app.url_map.converters['regex'] = RegexConverter

@app.route('/<regex("[abcABC0-9]{4,6}"):uid>-<slug>/')
def example(uid, slug):
    return "uid: %s, slug: %s" % (uid, slug)
