I am not a c partisan myself, but we haven't got much choice :)

Check out this one:
http://wit.mcs.anl.gov/~selkovjr/foldit.tgz
It may be incomplete for your task but it shows how to do it in
principle. You may want to add more character translations, and you
can do that without changing the code too much, by editing rules in
folditscan.l (at least, this is a lot easier than coding in c).
You won't have to touch the c code as long as the objects you want yylex()
to return will remain single characters. In case you want something bigger,
such as strings, the interface between yylex() and foldit() should be
changed
Further questions welcome,
