I'm trying to figure out how to prevent my recursive spec-based generators from StackOverflowing. From what I can tell the checks that are built in based on *recursion-limit* are moot as soon as you use with-gen.

I currently have two places where I'm using with-gen that cause recursion, https://github.com/lambdaisland/regal/blob/master/src/lambdaisland/regal/spec_alpha.cljc#L44-L47

https://github.com/lambdaisland/regal/blob/master/src/lambdaisland/regal/spec_alpha.cljc#L85-L95

The second one I could get away without the custom generator, it'll just do some extra work until it finds a valid value, but the first one is annoying. The spec boils down to (s/and (s/cat ...) vector?), but (s/cat ...) never generates vectors so when generating this tries 100 times and gives up

maybe there's a better way to write that? can I use regex specs but still convey that I really only want to match/generate vectors?

Not easily (this is something we’ve added in spec 2)

Hello! I've recently done some reading on clojure spec and have added it to some side projects of mine, but I'm a little lost on how/when to use instrumentation (or orchestra). I've spec'd multiple functions in my project, but realize those are useless (aside from readability) without running some sort of instrumentation. Are there any resources explaining how to integrate instrumentation in a clojure project? I don't want to permanently leave a call to instrument inside my clojure files, and only want them to really be run during development phase. Aside from just running instrumentation in the REPL during the dev process, are there any best practices for instrumenting in my project? Thanks 🙂

most useful in dev at the repl

but could also be useful to turn on/off in a fixture around tests
