Hi Usman,
Thanks for the script.
@Jan: could you look at it? I do not think it is a big problem.

Hi Doru,
We are using Platyplus to generate a language grammar and it uses
PetitParser for this purpose. When trying to synchronize the definitions
with Platyplus in the latest version of Moose, there are some errors
related to PPContext not understanding #position. And it seems to be
associated to the new changes.
Here's a script to reproduce the problem in Moose:
Gofer new
url: 'http://smalltalkhub.com/mc/AlainPlantec/Platypus2/main';
package: 'ConfigurationOfPlatypus';
load.
(Smalltalk at: #ConfigurationOfPlatypus) loadDevelopment.
PlatypusExpressEditor new synchronize
We might later in time try to adapt platyplus to the recent changes in
PetitParser but currently we have to concentrate on other things.
regards.

Hi Usman,
Could you let us know how you trigger the parsing? Could it be that you
are using some internal methods?
Could you reproduce this on any other parser?
Cheers,
Doru

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.
