Guts: Lexical Analysis -
The Perl Journal, Fall 1998.
This is a nice informal discussion of some of the complexities
in Perl's lexical analyzer. The interesting thing is that
lexical analysis in Perl is context dependent; so that a "{"
in one place is actually a different token than a "{" in
another place. Most programming languages are not written
that way.
In case you feel I'm short-changing parsing, how about the
yacc file (bison is gnu's version of yacc) for Perl:
perl.y.
Notice that it makes heavy use of associativity and
precedence declarations so that the grammar itself stays simple.
Yacc's shift-reduce parser uses these declarations to
resolve parsing "conflicts", i.e. to make the parse tree unique.
