Iceberg regex

by Ian Ian

Yes. That is how it is on github but there are private hit serveers. My own, for example. I found it usable after I changed the regex in both classes where it exists.

Running your drgeo.image on a recent linux pharo 64 bit vm gives this error message first: /home/nicolai/devel/pharo/Pharo7.0-32bit-52a28a8.sources.

After some looking into it I believe Mongo Voyager is the easiest given the current options. Too bad Gemstone limits usage after a given number of Gems. Too bad ObjectDB does as well.

Hi Hilaire your P7 image is older and has problems with FreeType fonts initialization that should be fixed in the newest builds. Maybe that is cause of the Athens issues you are facing.
