Yes, I need to rely on this position afterwards, for example, for relating model pieces to
the source code. The question is how to retrieve and how to store this information.
What you could do is just keep line + column number
since that stays fixed. Just increment newline on the systems newline sequence, and set
column back to 0.
Indeed. The problem is that the token of PetitParser only knows the character position
from the stream. This would mean that we would have to modify the tracking of the position
with extra information.
Is there no other option?

Hi,
I have a small problem related to file line endings and storing the token information of
PetitParser.
Sometimes, we parse the sources on Windows and then manipulate the model on Linux or Mac.
In this context, if I store the token positions in a string, I encounter problems because
CR and LF are considered characters, but the line endings can vary.
('abc', Character cr asString , 'd') findString: 'd'.
==> 5
('abc', Character cr asString , Character lf asString, 'd') findString:
'd'.
==> 6
How would you approach this problem?
Cheers,
Doru
