2452 :: Wrapping C library

• sdwfrost (orginal) [2016-08-09T11:57:00+02:00] view original

  Dear All,

  As my first try in Nim, I'm wrapping libRmath (actually a patched version https://github.com/JuliaLang/Rmath-julia). I have used c2nim to process the header. If there is a true/false argument in the function (as cint), how can I use Nim's bool type - automatic conversion to 0/1 doesn't happen.

  In general, is it better to make a low-level library, then write a higher level one that contains type conversions, default arguments, etc.? If so, what's the best way to do this?

  Best Simon

  I would suggest creating a low-level wrapper first, directly wrapping each function with the exact same C type arguments, so cint in this case. On top of that you can manually create a cleaner Nim library that uses the underlying wrapper, but converts regular Nim types to the C types and does some other bookkeeping.

  Dear @def,

  Do you mean something like this?
