What i do in Java is count "}" and ";".

To get a reasonable physical line count in Scheme, you could read each expression from the orignal scheme file and then pretty print it and then count those lines.

Ward Cunningham has an interesting way summarizing a java class by squeezing out all the characters that aren't "{", "}", or ";":

It gives you a quick summary where each Java file is one line, and you can see some interesting patterns.

I've recently been keeping metrics on programming tasks in C, and want
to do that on code in Scheme as well.  For C, I'm using the usual
"Physical SLOC" definition, which removes all comments and then all
blank lines (yes, this means that coding style makes a difference).
There are a number of definitions of Logical SLOC, but they do not
agree.  So, I took a stab at Logical SLOC for Scheme (taking advantage
of the clean syntax) and declared each '(' to be a single LSLOC.
(-LSLOC seems about 50% higher than PSLOC, at least for the
SLOC-counting program.
