Hi.
I'm working on yet another VIM emulation mode.
Currently I'm implementing EX commands. I've looked through VIM source
and found that EX commands are parsed by do_one_cmd function in
src/ex_docmd.c line 1686.
It is 1069 lines long...
After looking at it I have a question: is there some PEG, CFG, BNF,
... spec for EX commands?
Googling didn't help much, only some very basic stuff is done in Ragel
or LEMON parser generators.
Thank you.
Regards, Daniel.
