Use codegen for FFI / style builder about taffy HOT 2 OPEN

Is it worth looking at diplomat (used by icu4x)? (I don't know the answer.)

I think I looked at diplomat, but I'll take another look on your recommendation. So far every tool I've looked at has lacked I'm both language support (they all support a different subset of languages) and flexibility (making it hard to support different approaches in different languages). A lot of them also use a proprietary DSL which isn't always super clear for those unfamiliar (which will be most people as such tools are not widely used).

My feeling is that a small, well-documented 400-500 line script that does simple string-based code generation powered off a JSON file or similar would be easier to maintain and for newcomers to understand. Especially if the generated code is checked into source control and can be easily inspected and played with.
