Adding validation check for meta files

[arjunsuresh]

CM scripts can fail with unexpected errors if there is a syntax error in _cm.json/_cm.yaml files. It'll be good to add a quick syntax check for these files.

Interesting. I think scripts will report an error in the _cm.json/_cm.yaml file if there is a syntax error? Do you mean that we should we make error more user-friendly? Or you want some extra syntax check? We can discuss it during the conf-call ... Thanks!

Hi @gfursin , actually I'm referring to the internal semantics specific to CM like the type of tags being a string, env being a dict, deps being a list, adr being a dict etc. Sure, we can discuss this.

Oh, yes, that's very important! The idea of CK/CM is to enable very quick prototyping of ideas while gradually adding tests and safety including information about types. There are several ways of doing it. Let's discuss it at one of our future conf-calls. I agree that it becomes important now. Thanks a lot!
