Well, actually, generally gdb is able to provide the backtrace without any particular help from DMD. For some reason, it works better without debug info turned on in later versions (but without line numbers).

Sorry about that <g>. It is pretty awful. But goto roolz.

Lack of goto is one reason why I don't program in Java, I don't like languages trying to be my mom. There's no technical reason why Java can't have one, I know, I wrote a Java compiler.

It does in a limited form via labels and break/continue, but this obviously has far less utility than goto.

Some people even eschew break and continue as impure thoughts that must be cast out.

I ran across this. Hope it might help.

Already knew, but yes, it's a good article.

However, you seem to be far ahead of I've done. You say you've converted the whole D frontend to Java? (to descent\internal\core\dom\Parser.java I presume) That must have been a lot of work.

Porting c++ to Java was not an easy task, especially since Java has no powerful "goto" (oh my, 732 in the whole code), so I had to change some of the code, or duplicate it (I don't want to break anything at first).

Let me know when you get back. I have a lot of questions, it would be nice if we could exchange IM contacts (MSN, YM?), for now, I'm usually at the D IRC channel (bruno_m).
For starters: "Ported most of DMD lexer and parser code. " - What do you mean "most" ? And what task are you planning to do next?

My original planning was for me to do first an IDE-decoupled command-line tool that would perform some operations useful-even-outside-of-an-IDE, like code beautification or refactoring. This isn't just for project phased planning or code abstraction, I think it's a worthy goal of itself. Such IDE-decoupled tool could then be used by developers who use another IDE,editor (or none at all). Perhaps it could also be useful (by porting or direct use) to other IDEs in the future. (like Poseidon maybe?)
Anyways, I'm gonna keep looking at you code and what it can do, I still have only taken a quick look at it.

Which server? I didn't find it. My MSN is asterite ĉe hotmail punkto com.

In http://www.dsource.org/projects/descent/wiki/WikiStart I added a section below, "How to help?". There you'll find the explantation for "most". Actually, the lexer and parser code are ported, but the source ranges for elements are still missing for a lot of elements, as well as the nice AST interfaces.

Sounds like an interesting project, but I don't like the idea of a plugin using command lines. But that's just me.

> Anyways, I'm gonna keep looking at you code and what it can do, I still have only taken a quick look at it.

If you have any questions, don't hesitate. I suppose the little explanation on the dsource page won't suffice, but taking a look at which lines don't get covered by the tests gives a big hint on what to program next.

Party over at #D WOO WOO! Actually, there isnt one right now, but THERE COULD BE!
