Hello All,

I stopped development at DGrammar months ago (perhaps more than a year 
ago). Nevertheless, I have come back and have made some decisions about 
what to do with it.

1 ) DGrammar was build using YACC, and thus C, C++, Flex and Bison where 
necessary to get the beast compiled, and it didn't even do it's job the 
way I would like it.

2 ) DGrammar was a bit of "make one messy file" architecture, which of 
course isn't about a professional environment.

3 ) I've began at first writing boiler plate Machines. The first one is 
a PDA Machine (Stack machine), and I like it to be tested. Simply run 
"build" over dmachine.d. And enter something like:

"dmachine aabbbbbaa"

This is just an example, try to make some machines with it, I try to 
make it working better with the lambda problem I'm still having (it is 
solved Q&R now, which isn't the way I like it, any solutions would be 
welcome)

Regards,
Sjoerd

Sjoerd, have you considered using Enki to help you get development restarted? I know that the two projects share some basic similarities - heck, DGrammar is what inspired me to write it in the first place. Anyway, the whole thing is BSD licensed, so feel free to use it as you see fit. - EricAnderton at yahoo

Definitely consider Enki. The only difference is the way it is processed. At the end I want to let DGrammer use a "BDF" styled input file, and let it generate a parser. When that's done, I'd like for it to be able (just as in the first trials) to run it through some kind of interface architecture, making it a two-step process: Parsing and Processing, just as SAX does.
