I'm tinkering around with the original dmdscript a little bit, but it seems tedious. Even if V8 is better, I'd like to see, if I can get a proof of concept together at least, using vibe.d and dmdscript.

Here is the relevant parts:

char[] name;
int value;
char[] ident;
}
Msgtable errtable[] =
[

DMDScript was probably written for D1 and has never been ported to more
recent D.

RE: dmdscript osx.mak
Hi Robert and Dmitry, Thanks for your replies and the heads up on the current status of DMDScript! Josh
dmdscript osx.mak
Hello, I apologize if this is the wrong forum to post this question, but I couldn't find a corresponding learn mailing list for DMDScript. I wanted to play around with DMDScript but cant seem to get started. I downloaded the source and attempted to make it via: $ make -f osx.mak But I get the following error: textgen.d(132): Error: cannot implicitly convert expression ~ some string ~ of type string to char[] Am I doing the right thing? Or how do I go about getting building 'ds' so I can run simpleton scripts? Josh

Someone has updated dmdscript for D2, there's an announcement on digitalmars.D.announce about it somewhere. Using that version will fix your issues. -- Robert http://octarineparrot.com/

Still the D2 port should work with no problems. And even though I did it in the first place, the only benefit of it right now is that it's written in D and thus could be integrated with D projects slightly better. Still if you are up for some hacking give it a try. As for speed, yeah, it's something like around 20-200x slower at various workloads (e.g. numerics in JavaScript and such), so wouldn't recommend if you have performance in mind. -- Dmitry Olshansky
