No doubt about that - if it is being used.

Probably changes in GEGL - I will try to take a look this weekend - I was already using a non-standard constructor as I said (maybe it was Sabo's wrapper you mentioned in the other message.

There are tests in my module - possibly not many as there could be - I'd like to keep the its git separated due to the Python packaging ecosystem (and merging the histories would be a mess, I guess). Do you think it could work as a git submodule in GEGL? js -><- > > > > > -- > Jon Nordby - www.jonnor.com _______________________________________________ gegl-developer-list mailing list List address: email@example.com List membership: https://mail.gnome.org/mailman/listinfo/gegl-developer-list
