What kind of parser is it?
It's a direct parser with aritmetic subparser. Main parser is
grub_bash_execute, arithmetic subparser is grub_bash_eval_arith.
grub_bash_execute determinates the special cases (loops,conditions,
functions,...) for other cases (commands,assignments, function

I have never seen this in a top-down or bottom-up parser I have
I don't like to write the things reffering every time to algorithm.
Genereally I take some ideas and I write myself, at my own.
What do you mean?
The problem is that I like proven concepts. And when you use a
commonly known parser design many people will be able to understand
it. To me this is REALLY important. I wonder what other developers
think of that.
I agree. Hand-written parsers are very hairy to implement, with nasty
bugs and corner cases. Although I haven't studied the theory, I know
that there are traditional parsing/lexing/whatever techniques that are
In fact, there's a whole bunch of tools like flex and bison that we
could use to avoid hand-written errors. Why don't we use those?
