C compiler for SCM

This program is currently part of the SCM Scheme implementation.

Hobbit is a small optimizing scheme-to-C compiler written in R4RS Scheme and intended for use together with SCM scheme. It compiles full R4RS (with the exception of mutual tail recursion and hygienic macros) and supports defmacros.

Hobbit treats SCM files as a C library and provides integration of compiled procedures and variables with the SCM interpreter as new primitives. It compiles scheme files to C files and does not provide anything else by itself (eg. calling the C compiler, dynamic loading).

Hobbit (derived from hobbit5x) is included in SCM since 2007. Hobbit4d has also been ported to an old version of Guile.


Documentation included.

Previous version available in HTML and PDF format.
