Grammar railroad diagram

[mingodad]

I've done an extension to CocoR grammars to a kind of EBNF understood by https://www.bottlecaps.de/rr/ui to generate railroad diagrams see bellow the converted xcompiler/cocoR/abap_clean.atg and with some hand made changes to allow view it at https://www.bottlecaps.de/rr/ui the order of the rules could be changed to a better view of the railroad diagrams. Copy and paste the EBNF bellow on https://www.bottlecaps.de/rr/ui tab Edit Grammar then switch to the tab View Diagram.

Your grammar breaks other extensions I did in https://github.com/mingodad/CocoR-CPP and makes it enter a infinite loop trying to print a tree-view of the ambiguities, anyway I manually deactivated the problem and generated the EBNF bellow that I think would help debug/develop this grammar.

I'm interested in your project https://github.com/jackieju/xcompiler but could not see /understand it clearly (it seems tied to ruby only).
