Re: [Pharo-project] TalkFFI: automatic FFI generation for Pharo

by Ciprian Teodorov

hi Igor, Yes I have tried some little external libraries, nothing big yet (besides llvm, and libclang). For the moment I did not see any show-stopper problems... But there are still some rough edges. What I have under scrutiny right now are: - adding unions to NB - supporting vectors (and constant arrays, which are flattened right now). Vectors appear to be used in cblas. - there are some problems with my callback naming scheme, which I found trying to map Cairo. Besides these there are some improvements to NB, to simplify code generation and maintenance like: - an unified parser for the simplified c declarations. - unifying fieldDecl, enumDecl, fnSpec under a single naming convention... Maybe nativeSpec, or nativeDecl For the customizations I think right now is to early to say that I have a good interface. But certainly over time we will have different filters. Right now you can customize fct names using a block, and u can specify a prefix for the generated classes. I am also thinking about a graphical interface, somewhat on the lines of the dllcc in vw. Anyways I think using libclang offers nice opportunities, maybe retrieving comments from headers, or even autocomplete-like ffi generation... So yeah for now I will call TalkFFI a tech-preview... We will see how it goes ;) Cheers On Jan 7, 2013 1:13 AM, "Igor Stasenko" <siguctua(a)gmail.com> wrote: > > Wow.. that's great. > Having a way to automatically generate bindings makes life much easier :) > > Few questions: > - did you tried to run it against some libraries around there, except > from LLVM? > > - i saw, in video, you can customize generation a bit.. to what > extent?

Wow.. that's great. Having a way to automatically generate bindings makes life much easier :) Few questions: - did you tried to run it against some libraries around there, except from LLVM? - i saw, in video, you can customize generation a bit.. to what extent? Is there interface (suppose i want to use own naming prefix, suppress generation of certain declaration etc)? -- Best regards, Igor Stasenko.

Thanks Ciprian.

Hi guys, I have just uploaded a short presentation video on youtube (generation of LLVM mapping), so that you can get the taste of it. http://youtu.be/y_zfgUh27m0 On Sun, Jan 6, 2013 at 7:18 PM, Marcus Denker <marcus.denker(a)inria.fr>wrote: > > On Jan 6, 2013, at 7:07 PM, Mariano Martinez Peck <marianopeck(a)gmail.com> > wrote: > > That's super awesome.

[Pharo-project] TalkFFI: automatic FFI generation for Pharo

by Ciprian Teodorov

Happy new year everybody! I am pleased to announce today the initial release of TalkFFI. TalkFFI enables *automatic* FFI generation for Smalltalk. It uses libclang <http://clang.llvm.org> to parse *unmodified* C header files and generate FFI bindings to c libraries. For now it supports the generation of NativeBoost FFI bindings. The project is released under MIT license, and you can find it on the smalltalkhub site. http://smalltalkhub.com/#!/~CipT/TalkFFI Please do not hesitate send me your comments/critics/ideas.
