- fixed the ambiguous access to 'collection' in PositionableStream
I think that should fix your problem.

Ahh, of course as a temporary workaround you can use:
aParser parse: (StandardFileStream fileNamed:
'/some/path/to/file/atextfile.txt') contents

After further analysis, it seems that the problem
comes from asPetitStream
in PositionnableStream. This method checks if the attribute collection is
nil and uses the collection if it is not nil. In our case, the collection is
not nil but does not contain our file data, it only contains whitespaces.
The problem is about the behavior of our FileStream where before reading,
collection is not nil.
The question: does anyone have seen a similar problem with PP.
thanx

I do not understand what you are saying or asking.
Normally #asPetitStream should convert any non-memory stream to an
efficient in-memory representation. Maybe this does not work properly
in the Pharo version you are using? Or maybe your file is too big to
be loaded into memory?
While it is technically possible to use PetitParser on an external
stream (such as a file or socket stream) it is not advisable.
PetitParser requires highly efficient random access to the parsed data
and anything else than an indexed in-memory collection slows down the
parsing by magnitudes.

Hello all,
We are using petitParser with a Stream by the parse method on a
PPParser.
This parse method calls asPetitStream on our stream which is supposed to
return a stream with a valid format for PPParser. The problem is that
this
stream do not represent our test file but a lot of white spaces. this
code:
(StandardFileStream fileNamed: '/some/path/to/file/atextfile.txt' )
asPetitStream proves that.
Did someone else have a similar problem with petit parser?
thanx,
Usman & Guillaume
