This is also understandable. and a price to pay to have this system going forward. My point is the change was made, and no care for the users was made in either: - stating somewhere (maybe the list, a wiki, a faq) the consequences of this change and the advantages over the old code. - a way to migrate old code to the new code. This, at least for someone that has never used shared pools, isn't obvious. The issue tracker says something about importing the shared pool in the class using it so it can access its values. But there are package extensions that add methods to other classes that use TextConstants, how is one to work out this case, adding TextConstant sharedpool to the class (array in the case of magma that is augmented by a couple of methods that uses TextConstants) > Then TextConstants had different and bad use: > - storing constants > - storing volatile information about fonts and all sorts of registrations for fonts!!! in textConstants > "oh yes this is the dictionary so lets us mess there" > instead of using adequate classVariables in adequate classes (we should still clean this part). > TextSharedInformation below is for the moment containing all the crap. > I understand. > > What is the reason of this change?

Yes, I now, but this means that all the code using the at: message in TextConstants is broken in the new Pharo1.2. Maybe this hasn't been noted (at least for me it hasn't) because PharoCore 1.2 wasn't stable but now that is stable people will try to load code that uses TextConstants and if uses the at: message it won't work. Don't get me wrong. I am for the progress of Pharo and this change is in that direction but it appears to me that was without notice and without a deprecation warning akin to the method deprecation. This was released to the world without time for package to catch up and prepare either a patch to the code or a PharoCompatibility package that copes with usage of TextConstants. > > Now I do not really understand why a database has to change that kind of text information. > I don't know either because I'm not expert on magma but that is besides the point. Now what I will do is to add (after consulting with Chris) a Pharo specific package to magma, or if that isn't possible, an add-on in PharoTaskForces that is loaded after magma packages and overwrites the methods using TextConstants with the Pharo specific shared pool implementation. This I suppose will dirty the Magma package and I don't like it so much. So, dear Magma on Pharo users, the ConfigurationOfMagma isn't usable yet. Please wait a couple of days more. :/ Cheers -- Miguel CobÃ¡ http://twitter.com/MiguelCobaMtz http://miguel.leugim.com.mx

Hi guys, as Alex said we are currently working on a quite simple 3d library entirely based on Morph.
