Hi Kenton- I only see:

Knowing what file housed a particular node would be nice, but not strictly necessary. I'm writing software which takes in a capnp schema along with a bunch of other stuff. It's basically a message passing compiler which can #include capnp schemas to use for message schemas. Only there's no language associated with it, so a source-to-source translator (codegen) doesn't apply. ~John On Thu, Jun 18, 2020 at 4:59 PM Kenton Varda <[email protected]> wrote: > Hi John, > > `capnp::SchemaParser` will parse capnp files and give you a > `capnp::ParsedSchema`, which is like `capnp::Schema` but also has the > `getNested()` method which allows you to traverse the whole tree of child > nodes.
