I just realised, it was not your grammar, which I tried to convert. It was the grammar I found in the lr-lalr project on dsource.org. (it seems
to be an abandoned project)

Now I spent the whole day to extract the grammar from the spec and bring it in a valid GOLD grammar. I fixed the first few conflicts, but I realized, that it will be an endless story to fix them all. It's to much to overlook at once. One should write the grammar in small steps. But anyway, I abandoned int and will use the JSON output for now. It's quite simple to parse and I think it's enough for the first step!

It's still in its early stages and there is a lot of work to do, but it will be finished soon (hopefully). It could probably become a part of an official distribution, eventually. :)

Hi, Denis!

I am beginner in D, but this theme is interesting for me - I very much would like to take part in creation IDE.

I am interesting. I'd like to help.
I hope I'll be able to help you?

Contact me please at sableteeth@gmail.com
Sincerelly, Sergey
