There is test.chuck, a library that can create generators from regex.

That is what I am doing but I then have to remember to add all the extra generators. I want to be able to create my own schema and generator like the ones provided

Create a custom generator that uses a custom leaf generator seems the way to go. https://github.com/plumatic/schema-generators/blob/master/src/schema_generators/generators.cljc#L192
