C-bsaed S-expression implementation

[Dave Bakhash]

Hi,

I was wondering if anyone's had success with a particular C
implementation of an S-expression parser. I'm looking for one that's
very small and tight, and writtin in ANSI C, without need tons of other
libraries. I guess I don't need it to support the full set of CL sexps,
but a reasonable subset at least.

thanks,
dave

We have been using the CRSCL (Contains a Reimplementation of a Subset
of Common Lisp) library to read S-exprs in a variety of programs. The
library is based on an old one originating from Berkeley (and it bears
the same licensing style). I kept tweaking it over the years to make
sure that the reader behavior gets closer to CL, but it ain't a full
blown CL Reader (no reader macros!) and there is still a huge amount
of kruft in it.

It serves our purposes and it does a good job at reading simple
S-expressions.

Write me if you need it.

Cheers

I've successfully used SIOD (http://people.delphi.com/gjc/siod.html) for
this purpose. It's yet another dialect of Scheme, but is culturally
close to CL (car and cdr of the empty list don't error), and obvious
S-expression utilities like assoc are close at hand.

Someday, in my Copious Free Time(tm), I must ball up my SIOD hacks and
submit them...
