Re: [Pharo-users] [ANN] Arff generator for Pharo
Took me 1 hour to create 1 object/concept and the visitor. My classmates probably did it with Python but not in the spirit to share it so I guess it took them less time but it is not reusable... :) Then some time to document, write the baseline and the mail.

[Pharo-users] [ANN] Arff generator for Pharo
Hello everyone, For a university project in ''Datamining and Datawarehousing'', I have to convert data stored as text files in different formats to the Weka[1] ARFF format[2]. I did it with Pharo of course! :) So, I wrote this little project [3] to share what I have done with you, just in case someone else needs to export data from Pharo objects to an ARFF string for further analysis with Weka.
