Hello Sina,
Well for me reading a source code and learning from it is harder than
understanding the algorithm and figuring out how to write a already
well underwstood and planned thing. I don't know nothing about
parsers, like if you ask me now to do a c++ syntax analyzer I don't
think I can do it right now, because I can't figure out by my self
what steps are necessary and how to implement it. I have been looking
for tutorials on it, but most part of them use graphycal
representations of concepts or are more concentrated to show "how to
do" and not "how it works".
As Jamal is a nice guy in terms of helping I wanted to study his code
and ask him questions, but a book on the subject would be cool. I am
not a bite counter, and I am better in using logic then in pure math.
I am also a programmer used to do medium level programming, so it
would need to be a not advansed, but not so basic book or something
similar.
I am not doing parsers in my work, this is a subject I am just
interested for but I ahve not still been able to find helpfull
material. I would like to try first doing simple parsers, but after
this when I am good at it I really would like to implement a pre
processor like the C one to parse other language files, but this is a
pretty advansed thing I plan to do latter.

When you say "I wrote a program that crashed Windows," people just
stare at you blankly and say "Hey, I got those with the system, for
free."
