I can currently write Ruby code in C, using Ruby's C API. This is much faster
than native Ruby code and allows me to use the C-code from within the Ruby
object model. For this to work, the C code must be structured in a certain way,
and using pre-defined types, macros and function signatures, example
[here](https://gitlab.com/snippets/1661089) .
I would like to be able to produce this code from Nim. My question is: how can
I do this? The way I see it, I have 3 options:
* Modify the Nim compiler. May be create a cgen-like module that understands
the Ruby C-API semantics and generates appropriate C code. Then I could do
something like
nim c --cc:gcc --ext:rb mycode
* Create a new DSL (macro) library that generates Ruby-structured C code from
templates (a bit like [emerald](https://flyx.github.io/emerald) I guess)
* Create a token-based generator that formats C-code according to
tokens/annotations (a bit like the docgen tool)
I'm thinking out loud here and any opinions / suggestions are welcome.
cheers
