asn1c VS ruby-skyjam

I had to use it at work in a C++ environment and ended up settling on patching a copy of https://github.com/vlm/asn1c

Can't say I'd feel confident putting any of this stuff in a public service. Too complex and prone to bugs.

I've used ASN.1 at work quite a bit, and the reason you won't see it much are pretty much:

- HORRIBLE schema format.

- Very few FOSS libraries, most of which are terrible. I used Lev Walkins asn1c[0], which I patched slightly and coupled with some semi-generic code to emit JSON (for debugging purposes).

I found code generation to be useful in Ruby with protobuf. This:

gives that:

I would certainly enjoy having a DSL to write descriptive code to validate using JSON schema, but it would be even better if the Ruby definitions could be generated and persisted in Ruby files using that DSL.

Also, storing things in basic hash/array types works, but having dedicated types is useful, so that one can ensure not shoving one kind of hash in place of another unrelated kind of hash.

As for types themselves in general, there's RBS and Sorbet. One could have type definition generation as well for even deeper static and runtime checks.
