Happy new year’s eve, everyone! I’m working on writing some form validation for a web application. In my web app, most of my requests have well-formed request bodies that are known ahead of time. However, some of the requests have fields / properties whose structure is determined by metadata entries in my application’s database. Is there a good example somewhere of programmatically generating Clojure specs for handling these at runtime? So far, I’ve found that I can create a spec with (s/spec int?) (for example), but then I’m not sure how to use that with (s/keys) as all of the s/keys examples I’ve seen require specs to be registered in the global spec registry. Any ideas on how I can do this? Do I need spec2 for this? Also, it’s worth noting that changes to these metadata DB rows are infrequent enough that I could probably create the specs by reading the DB when the application first starts, but I’d like to avoid doing that if possible.

you certainly can register the specs dynamically but it requires a bit of care with macros or eval to do so. spec 2 is a little friendlier for this use case but is not ready for real use yet

Okay, thank you, Alex. I just found https://github.com/metosin/spec-tools, which might fit my use case. TBD
