Re: [Pharo-project] Versionner in pharo 2.0

by Norbert Hartl

Hi, I fixed the announcements already and got to the metacello toolbox problems. It is complaining a version (actually a baseline version) does not exist although it is defined in the configuration. If you are on it I'm happy to shy away. My time frame for it is over anyway. Just to let you know that you have one lucky customer for anything you'll achieve. Let me know!

btw... why is there a ConfigurationOfVersionner in verified repo for 2.0 if it is not working (and therefore, it is not "verified")?

Hi Norbert, Here is a patch for announcements (and some other things) for Versionner on Pharo2. Unzip, add this folder as repository in Monticello and load latest packages versions. After that, I'm not sure it will help you because there are issues with MetacelloToolbox. I'm working on that and I hope to have good news soon. Regards, Christophe.

Re: [Pharo-project] bump: pharo wikipedia page sucks

by stephane ducasse

Yes but also I do not want that people think that I want to have less Squeak on the pharo page. To me a Pharo page should be about: all the history about the squeak fork is now history for me. As a newbie I wante to get excited by pharo not understand the history of ant fighting while elephants are running around. The license story is also a pain. I would move all that into history.

In pharo 2.0 when you rename a method and then click on the old selector both methods are selected and shortcut invocation for deleting deletes both. Which is quite annoying. In my opinion there is no reason for two methods being selected.

When PluggableIconListMorph updates the list selection it calls the MethodWidget to set true on the new method selected.
