Writing a scanner and parser in Ada

[Yves Cloutier <yves.cloutier@gmail.com>]

Hi there, 

I'm new to Ada, but not to programming.

I'd like to know if there are any examples of how to write a scanner and parser in Ada.

I have a pet project where I have a DSL that I want to use as input, scan, parse, then output as Groff code.

I've done a working prototype in Perl, but have been putting off writing it in a real :) programming language.

I'd rather not touch C. I started a skeleton in D but I've always wanted to put some effort into learning Ada.  From what I've seen it seems like a strong and mature language, but the very small number of books out there (and most only covering until Ada95) have made it a bit offputting. But lets see what I can do anyways!
