Is Rockit abandoned?

[Yuri Leikind]

Hello all,


Looks like Rockit, the OO parser generator for Ruby, is abandoned.

It doesn't work with its own examples:


leikind@pc324:~/rockit-0-3-8/examples/calculator$ ruby calculator.rb
/usr/local/lib/ruby/site_ruby/rockit/rockit.rb:24:in
`generate_parser': undefined local variable or method
`rockit_grammars_parser' for Parse:Module (NameError)
from calculator.rb:36:in `calculator_parser'
from calculator.rb:52

And some others have had similar troubles:

Anyone worked with Rockit recently?


Best regards,
Yuri Leikind

Hello all,
Hi,

Looks like Rockit, the OO parser generator for Ruby, is abandoned.

Its been abandoned for some 2 years but I'm now working on it again.
Instead of fixing the old version I've decided to do a new one
with a C backend. Expect release in 3 weeks.

Sorry for the bad support these 2 years,

Robert Feldt

Hmm, do I smell speed?

Does / will Rockit support scannerless parsing? i.e. allow me to combine 2
separate grammars (e.g. Cobol and SQL) and not have a lexer that imposes
Cobol keywords as restricted words in the SQL sub-expressions?

Thanks ...

Its not top prio but parsing is one of these things
were speed really can matter so yes, I think it will have
enough of it to be generally useful.

My goal now is to generate a Ruby C extension that gives
a parser. I think for many uses this will be good enough.
Long-term, yes, a pure-Ruby solution as an option would
be good (especially to experiment with intelligent
error reporting which is much harder in C) but don't
expect it anytime soon.

Regards,

Robert
