Hi, short: we need some advice/help on the parser :) This mail was posted to jython-dev as well. Please reply if you have some answers to the following questions.
We're working on a Eclipse IDE Python Refactoring plug-in (open-source, LTK based), see http://sifsstud2.hsr.ch. We're facing 2 main *challenges* using the jython parser (working on PyDev's jython parser provided for Python 2.4/2.5 grammars): 1. BeginColumn provided are wrong sometimes (we really need correct values here for correct indentation) 2. Visitor pattern is not applied for all nodes as expected (sometimes nodes just get traversed.. unnoticed by the visitor) .. less important: 3. Num-Node didn't provide enough information (fixed by providing numType). 4. Comments may disappear BeginColumn: We would really appreciate some advise/help on this issue! ClassDef/FunctionDef e.g. have correct beginColumn values... but e.g. Assign-Nodes usually not. Can someone check this behaviour and confirm ... give some advice how to fix it or even provide a fix? Visitor: I wrote an AST rewriter visitor (AST -> source code, works quite well) and noticed that *not* all AST nodes are "properly" handled by the visitor pattern. 1. Is there any reason why some nodes shouldn't be noticed by the visitor (accept(VisitorIF visitor) just traversing its "child" nodes, not calling any visit...-method provided) 2. We would like to contribute our change proposals later ... is the Jython/PyDev project working together? Where should be post change proposals? Currently certain nodes are handled differently, but it would be helpful if the visitor would work like expected. Please visit http://sifsstud2.hsr.ch/peptic/wiki/Rewriter#Nodeswithoutvisitorcallback for a more detailed description.
