I'm trying to port QuasiQuote package from Lukas Renggli to Pharo 3.0/4.0. This package use the RBCompiler class from the AST-Compiler package available here: http://source.lukas-renggli.ch/helvetia
If I understand RBCompiler, this is a Compiler that use RB parser nodes. I guess this is something that is no more relevant with the new Opal compiler ?
Yes, this is the PetitParser based Smalltalk parser that created RB ParseNodes.
Opal has a pluggable architecture for the parser, right now it just uses the hand-written RB Parser that came with the refactoring browser.
It would be very nice small experiment to plug in the Petitparser based one.
Especially interesting: Would it be much slower? Hi Markus,
Jan Kurs and me are now working on some PetitParser stuff. If we succeed then PetitParser-based parser would be as fast as current hand-written RBParser. We're at the beginning but preliminary benchmarks are very promising.
Error recovery and incremental reparsing are in the queue (if we find a time :-)
