Should regexes in path params be automatically removed?

[Wim-De-Clercq]

Failing test here: https://github.com/Wim-De-Clercq/pyramid_openapi3/commit/e15ebc369197c5b2dc0523b153ff6bcab040b426

We can't add the regex definitions in the openapi yaml because openapi doesn't support them. Neither is there really a need for this, because the Openapi schema works fine as it is in the test.

The problem is that to guarantee correct routing within pyramid we need to:
A. Either not use regexes in the path and rely on the order of the routes in pyramid. This isn't great and a bit prone to failure when the routes are included from other projects, or the routes are automatically added via scanning the @view_config (I think).
B. Do use regexes in the path. This guarantees correct routing, but doesn't currently work with pyramid_openapi3.

I think pyramid_openapi3 could simply remove the regex definitions similar to how it removes the prefixes at

pyramid_openapi3/pyramid_openapi3/__init__.py

Lines 327 to 336 in 60e803a

	def remove_prefixes(path):
	path = f"/{path}" if not path.startswith("/") else path
	for prefix in prefixes:
	path = path.replace(prefix, "")
	return path
	paths = list(openapi_settings["spec"].paths.keys())
	routes = [
	remove_prefixes(route.path) for name, route in app.routes_mapper.routes.items()
	]

Is this something you agree with?

Should we instead raise an error in pyramid_openapi if we come up against a regex in view path? I'm a bit afraid of silently removing parts of the path, I prefer to be specific with an error saying "Hey, regex paths are not supported in OpenAPIv3 but you gave me a path with regex so I don't know what to do here, please fix".

Hey @Wim-De-Clercq, do you have any further thoughts on this?
