Re: [Pharo-users] Using a private git repository with Metacello

by Thierry Goubier

Hi Julien, it should be possible on Linux and Mac OS by loading GitFileTree and using an url like: 'gitfiletree://bitbucket.com/owner/reponame&protocol=git'.

Re: [Pharo-users] About Zinc http components

by Alain Rastoul

Sorry, I think I have screwed my tests, I wasn't able to reload it right now (I think I was browsing the changeset while loading 0mq package in another image). There are missing references and lot of errors I will investigate later, I have other works in progress, and this one is in my list later, If I get it working I will contribute with my changes ... :) BTW this link is worth knowing about, thank you for the link.

Yes, Athens works with Floats.

Anyway it improves the accuracy in my case to redefine this center method in my Morph context. And it looks like Athens works with Float.

Ok, found my mistake. It should be 'pharo3.x' etc., not 'Pharo3.x' (case sensitive) -- View this message in context: http://forum.world.st/Configurations-based-on-version-of-Pharo-tp4783486p47… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Faulty point seems to be Rectangle>>center. May be some other ones to find. But not sure what to do with it, should it lands on float and not integer?

Configurations based on version of Pharo

by Jan BlizniÄenko

Hello In our project we have different versions of packages for Pharo 3 and Pharo 4. I would like to make ConfigurationOfOURPROJECT which will automatically detect Pharo version and use correct package. I tried development: spec <symbolicVersion: #development> spec for: #'Pharo4.0' version: 'Pharo4'. spec for: #'Pharo4.x' version: 'Pharo4'. spec for: #'Pharo3.0' version: 'Pharo3'. spec for: #'Pharo3.x' version: 'Pharo3' but it does not understand this 'PharoNumber' condition, it always looks for #'common' in both Pharo 3 and 4. If I insert line spec for: #'common' version: 'Pharo4', it always uses that one and loads version Pharo4, even in Pharo 3. If I keep it like this, without 'common', it throws error that no version found for #development Jan BlizniÄenko -- View this message in context: http://forum.world.st/Configurations-based-on-version-of-Pharo-tp4783486.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
