Hi,
I tried to update PetitParser so that it converts a stream into the PPContext. Therefore an entry point to the parsing looks like this:
PPParser>>parse: anObject ^ self parse: anObject withContext: PPContext new
The PPContext enwraps the PPStream and should provide the stream protocol.
I also updated the PetitSmalltalk project (version JanKurs.71).
The drawback of PPContext (that I am aware of) is approximately 10% slowdown. If there is anything else, please let me know so that I can work on it.
Cheers, Jan

Here's a screenshot of the debugger that popups when I execute some tests with the recent changes. It seems to be related to the problem of PPParsers knowing a context object instead of a stream. [image: Inline image 1]

Hi,
These changes should be backward compatible. What kind of impact did you experience? Can you give concrete examples?
Cheers, Doru

Hi all,
Recently, there have been changes in PetitParser related to support for island grammar and parsing context which requires some modifications in the tools using PetitParser. Not all tools can be adapted immediately to use the new version. Hence, I have created a new version of PetitParser that loads the packages prior to these changes for backward compatibility.
Name: ConfigurationOfPetitParser-usmanbhatti.49 Author: usmanbhatti Time: 28 September 2014, 8:58:00.540857 pm UUID: 54877ca2-77b0-4c5e-937d-5124dd76b075 Ancestors: ConfigurationOfPetitParser-JanKurs.48
adding a baseline and a version that loads packages before changes made to petitparser related to parsing context and island grammar.
