Hi all I would like to be able to use regex as part of the

FromProviderState

matcher. This would look like something like this

FromProviderState(expr, example, regex)

. This would allow me to enforce a tighter rule on the format of that field, which could be useful because I have no guarantees that the the value returned from provider state complies with the format the consumer is expecting. I cannot implement a custom matcher because the

Matcher

interface (in

matchers/matcher.go

) has a private method

isMatcher

-- preventing implementations outside of the

matchers

package. Is anyone aware of an alternative ? Is it worth creating a issue to convert the

isMatcher

into a public method ?

It’s private because you can’t just add new user-defined matchers

Thanks @Matt (pactflow.io / pact-js / pact-go) Any idea how I could validate the attribute matches the regex? Short of building that validation on the state handler -- I don't like this approach because it wouldn't be reflected on the contract.

I don’t believe you can put a regex matcher in there, it can only check the type of the value provider

Thank you Matt
