2939 :: Writing Ruby-C extensions in Nim

• RedFred (orginal) [2017-05-03T22:30:23+02:00] view original

  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 .

  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
  
  Run

  • Create a new DSL (macro) library that generates Ruby-structured C code from templates (a bit like 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
