Discussions about the virtues of Lisp syntax arise perenially. Although
I personally like prefix notation, I have to deal with customers who do
not, and who will not change their minds any time soon. Therefore, I
have written a partial C syntax parser in Common Lisp. Currently it
handles expressions only, not statements (e.g.: x=foo.baz[3+z] ==>
(setf x (aref (struct-ref foo 'baz) (+ 3 z))) ) It should be easily
extensible to parse C control constructs, although how much of that
would be desireable is debatable.
In any case, I have two questions:
1. Has anyone else done something similar that they are willing to
release? I prefer not to reinvent wheels.
2. Is anyone interested in a copy of my parser? It is of limited
utility as it stands, but it might make a useful building block.
