Hello!
No, I don't know D... It's incredible how many languages still keep emerging.
I have used Bison to process some languages (C headers and one language called
TTCN3) and to parse execution logs, nothing special I guess.
One thing that I have always encountered funny in Bison is the way to describe
lists. For example, if you expect comma-separated list called my_list, you
would write:
my_list: element | my_list ',' element;
I believe there could be some more elegant syntax to avoid that kind of loops.
I don't know how much we can make up, but creating a simplified expression like
this would help:
my_list: %list ',' element;
The directive %list would expand that expression into the previous one.
I've also had problems generating the grammar in C++. Right now I only use C
version of the code because of compilation/interaction problems with the lexer
(I used flex). I don't know in which side is the problem, but every time I had
to mix up C++ code from the project and C code from the parser/grammar resulted
in a mess... Especially when I wanted to wrap different parsers in different
classes and objects. Solving this would be a big improvement for me.
I can use github if it's more convenient. I can adapt to anything right now.
I will take a look again at the pending tasks.
BR,
Victor

Sure. It makes a lot of sense :)

I'll also send you a disclaimer form: contributions to Bison must be comply
with FSF rules.

I would say that you should start with something you are interested in, i.e.,
that you would like to use in Bison. What's your current use of it?

Good to know, thanks! You would be good at D too by any chance? We need
someone for D :)

M4 is special, no doubt about it. But in a sense, it's a functional
programming language. At least, most part of our use of M4 is FP style.

Whatever it needs.

See all the information Adrian sent. I would also add that if you plan to work
on GitHub, it would make sense to fork my repo
(https://github.com/akimd/bison). And them, take some time to read README and
README-hacking.
