Show HN: How I used Chicken Scheme to build registromat.com

I recently became Scheme-curious...

I'm not particularly interested in a web framework at the moment but I am interested in the process of making Scheme bindings for C libraries

Clearly it's fairly straightforward, at least for libs with small interfaces https://github.com/Mathieu-Desrochers/Schemings/blob/master/...

I've never used them directly but I know in Python there are libraries which can (partially?) automate the process of generating bindings, e.g. https://pythonhosted.org/PyBindGen/tutorial.html#header-file... ...it seems like this would be useful for libraries with a large API surface

Is anyone aware of such a tool in any of the Schemes?

Let me google that for myself...

There is SWIG http://www.swig.org/Doc1.3/SWIG.html which can auto generate bindings from a .h header file (though they recommend manually writing interface files instead of blindly binding everything)

and SWIG has output templates for Chicken and Guile Schemes http://www.swig.org/Doc1.3/Chicken.html http://www.swig.org/Doc1.3/Guile.html

Is this the best way to go? Other tools?

I had to read it a few times to understand what it is. It is something like "Chicken Scheme+Batteries"? You wrote the wrappers for the libraries and the autoinstaler?

Bravo. FFI for the win.
