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.

adding a baseline and a version that loads packages before changes made to
petitparser related to parsing context and island grammar.

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

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.

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

using some internal methods?
Could you reproduce this on any other parser?

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.

Hey,
I added #position: and #contents selectors to the PPContext. The script
should pass now. Please, let me know, if there are any other problems.
Originally, I decided not to include these selectors so that the developers
of new parser combinators are aware of the changes in the PetitParser (and
the integration of the PPContext is reasonably easy). Now, it seems it will
be better to include these selectors to make it easy for the users of
PetitParser.
Cheers,

just tried it and there is another error (method deprecation) in
PPExpressIdentifierParser>>failureTokenFrom: token
^ PPFailure message: 'Identifier expected' at: token position
no time to look at it now, but just substituting message:context: to
message:at: does not work

Hey,
I added #position: and #contents selectors to the PPContext. The
script should pass now. Please, let me know, if there are any other
problems.
Originally, I decided not to include these selectors so that the
developers of new parser combinators are aware of the changes in the
PetitParser (and the integration of the PPContext is reasonably easy).
Now, it seems it will be better to include these selectors to make it
easy for the users of PetitParser.

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.

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.

Hey,
this is actually a bit different issue. The PetitParser now reports the
furthest failure, not the last failure, as it is supposed to give more
precise error locations. And the furthest failure is remembered in
PPContext, if you don't specify the context, you can't remember it.
Therefore the method is deprecated.
I am not sure, if it is a good approach (I would rather see reporting
errors in a proper way), but I un-deprecated that, so all the tests from
PetitStepExpress package pass.
Cheers,
Jan
