Hi,
just forwarding to this list (is originally on d...@daffodil.apache.org).
It would be a nice addition to mspec (no worries chris, we'll keep that, ofc)
but it is way more powerful, I guess.

Hi guys,
I just had a discussion yesterday with Mike and Steve and we already had
several discussions before in the PLC4X project.
We like Daffodil but have the issue that we do not fit with the
“Interpreter” Runtime it currently is.
Mainly for two issues, performance and interoperability.
So Ideally, I would like to have a piece of code which takes a DFDL Schema
file and generated Code which is specifically to parse the given schema,
probably in a given output. Ideally in multiple languages.
As its not (yet) Christmas, I guess I will not get that for free so I
played around a bit with the code and tried to understand it as good as
possible and for me it seems that it is not that undoable as I initially
thought (I already checked some months ago).
In fact, if I get it right, the key would be to add another method
`translate: AstNode` to the `Parser` trait.
This should then generate an Ast (Sub-)node which represents all the action
that would be done in the regular `parse` method.
Then, we could finally, try to translate this Ast to Code and dump it to a
file (I guess this is the rather easy part).
This is just a rough thought, but I wanted to get it to the list and
probably we will find some time to discuss it at ACNA.
Julian
