Hi alberto,
i'm not sure about the solution of your problem although i would try to prepare a simple st script were you basically say to the parser which file to parse and simply flush on a file the output of the parser. Than you can start an headless image passing the st file as input. Hope this will help.

Cheers,
Fabrizio

Hi all,

�I have a small parser written in PetitParser ;) I would like to call
it from a non Smalltalk application (e.g., Java, javascript) or, more
generally, from a Unix command line.
I was thinking about something like:

./myParser -i fileToParse.txt -o outputFile.txt

Is there any possibility to do that? Can a headless Pharo be a
solution? If so, how can I start and use a headless Pharo? Is there
any useful documentation/email about it?

Thank you a lot for any help.

Cheers,
�Alberto
