Yes.

With respect to that...

awhile ago, I wrote a little Python script to convert a certain subset of C++ (that which is used by DMD) to D.  It handles most everything I've tested it on. (#ifdef, pointers, arrays, etc)

To use it, just pass the name of the .c/.h pair as an argument, eg:

    python c2d.py expression

It will parse expression.c and expression.h, and produce expression.d.

Maybe it will save you some time. :)

Thanks. I am sory that i don't have more time so i can explore python because i have never used it before, so when i do get some free time i think it will be easier for me to convert Walter's lexer from C++ to D.

so can we do ctor() instead of this()?
and the postfix var.cast(TYPE) ?

Well i like this so the first answer is no ;)-
I'm going to do the postfix cast these days.
And add it to dsource, it will be part of lr-lalr
project. So anyone can add things.

This is very cool!  A substitute for array arith ops till 2.0 maybe :) ?  Lots of other cool uses Im sure.

Where can we get it ?

Thanks. Each looks like a good substitute for array ops.

It will be added to lr-lalr parser project on dsource in a couple of
days but it is still mostly a toy because i don't have much time to conect
it to a real lexer (like Walter's).

hey is there any chance i can get this c2d.py from someone?

Well, Andy's URL is now http://aegisknight.org/~andy/d/, but I'm not sure if that particular file is there since I'm having trouble reaching his website right now. I don't know if the server is overloaded or if the server is just ticked off at me.

If the file isn't at the new website, I should have it burned onto a CD at home. If I remember, I'll try to find it this weekend.
