An experience with antlr, java and python

Help With My Hw I was trying first to create the parser using GNU Flex and Bison in C, probably the best way for a very performancing parser. http://verkehrsverein-guntersblum.de/william-lane-craig-masters-thesis/ William Lane Craig Masters Thesis Yeah, that’s right.. but looking at the antlr syntax I realized that’s easier and easier. Childrens Dictionary And Homework Helper Moreover I start using this very useful eclipse plugin for antlr debugging which made my life easier!

Everything works fine also for python, but I realized that the python script were so much slower than the java one!

So I run the python hotshot profiler to see which could be the bottleneck in the python script and I found most of the problems were due to unuseless antlr (the python module) method’s calls.
After making corrections to the antlr.py file the same script took exactly half of the time. Now 3 seconds. Wow 🙂
But not fast enough.
So I enabled for the antlr python script psyco module and this time the same script took Research Paper On Business only 1.6 seconds.
Now the python script is fast enough, even if I’m sure I can make more optimizations in the antlr module…
