I need to write a lexer / parser for a language like SQL and thougth this was the perfect change to learn D. Any comments, advice or tutorials that you can recomend.

Thanks.

Look at Walter's frontend source code...

How would a D parser in C help with writing a parser for a SQL-like language in D?

It helps writing parsers in general. IMHO there is no big difference between C and D for Parsers. The concept is still the same.

A while back, I converted a program called D2HTML into another program that attempts to produce syntax-highlighted webpages. I haven't spend much time on the SQL analysis part of it, so there's probably a lot of unnecessary code. In case it makes a difference, it was targeted at Microsoft Access-style SQL.

Maybe this will help you figure out how to accomplish your goal, so I'm attaching the code and the other files needed to use it.


If you're looking for general D tutorials, try: http://www.prowiki.org/wiki4d/wiki.cgi?D__Tutorial

A small digression, being in a suitably bleak mood at the moment:

"Microsoft Access-style ___Standard___ Query Language"

In all honesty, go use a prebuilt solution, and do something less painful to learn D!

Check out www.antlr.org for a great parser toolkit that already has a SQL grammar for it.

For a very calm introduction, you may like

It doesn't cover many things, but i liked it. I work somewhat differently for my purposes, but the basic ideas are the same. Don't hesitate to ask me questions, we will work out some solutions.

Otherwise, you may want to use some parser generator - i half-way even ported COCO/R to D, but then decided to change the direction and change the C version instead of porting the Java one. If i have time next days, i do that.
