Hej List!

I just pushed a ANTLR4 LEF grammer into[1]. My plan would be to:

• finish the DEF grammer
• do the LEFDEF c++ datastructures
• do a writer to ALF/LEF/DEF from this datastructures (allowing to write the subset of LEFDEF in ALF)
• integration in Qtflow
• make a extension for the LEFDEF datastructures for supporting ALF
• integration in Qtflow

Its my first ANTLR gramer, so feel free to critizise and improve.

As I just copied and rewrite the rules from the manual it should be more or less standart conform. In the listener or visitor patterns the logic has to be checked as specified in the refmanual (ie. increasing values, range limits, interpretation as int or float)

Sorry for being of in communication. I am in columbia visiting my girlfriend, next week will be without internet ^^

Greatings, Paul

Well, the right repository is IMHO
https://github.com/libresilicon/alf_parser

If there is someone beside arBmind who is interested in writing the ALF
parser - please drop me a note. I am currently the admin for
libresilicon on github and could give the permissions to commit there.

Regards,
Hagen.
