Hi Stefan, FWIW
Each of the different target languages is created and maintained by different people/groups. See http://www.antlr.org/wiki/display/ANTLR3/Code+Generation+Targets If you check http://www.antlr.org/wiki/display/ANTLR3/Antlr3PythonTarget you will see "Please note that the Python target is (compared to most other targets) rather young. I would consider it to be in *beta state*." Since Terence creates and maintains the Java version, the decision is obvious; pick the Java target. My guess is that most of your work will be in creating a PERL grammar for ANTLR and doing the AST rewrites. You will probably need to write some Java for the predicates but that will be a lesser of your worries. Note: I did not find a PERL grammar at http://www.antlr.org/grammar/list Best Wishes, Eric On Thu, Sep 15, 2011 at 9:43 AM, Stefan Mätje (d) < stefan.mae...@esd-electronics.com> wrote: > Hi, > > I'm facing the task to build a language to language translator that should > translate the programming language PEARL to C++.
