Ruby.h (et al.) documentation for D bindings


I’m writing a library for developing Ruby native extensions in D

One of the most important parts of it is a set of bindings – ruby.d
converted from ruby.h via a special program for that (D language
cannot read C .h files). As for now I’ve been OK with (sparse)
documentation in README.EXT and pickaxe book, with occassional
googling thrown in. But I’m in bigger and bigger need for a decent
Ruby API .h reference, with explanations on what do functions do (for
instance, what’s the difference between rb_str_new, rb_str_new2 and
rb_str_new3) – their names are sometimes not enough.

I know about Doxygen, but it’s just listing methods and references,
not giving a lot of helpful explanation. So, could you point me to
some resource documenting Ruby’s C API with all its subtleties?

Question as for now: I have a C float/double variable, I want to
convert it to Ruby’s Float. Only function I’ve found is rb_dbl2big and
I’d love to convert to Float, not BigNum. It’s documentation and
implementation on Doxygen is quite cryptic, to be honest.

Thanks in advance!

OK, I’ve found rb_float_new – so my last question is irrelevant.
Corelib.rubyonrails with “view source” for the win!

Question about good API reference still prevails though :slight_smile:
