Re: [Pharo-project] 1.2 Dev and Hudson

In Moose, we load the default baseline (this is a baseline that is meant to be changed) :). With the new Metacello, when you will have the symbolic versions, you should simply load that one.

I guess I could convert it to a ByteArray. But I still think there's a bug here: printing the hex value of a Character should add the leading zero, because they're represented by a full byte. So, I propose this change: Character>>hex ^value printStringBase: 16 nDigits: 2

Yes, as Guille said, using #lastVersion would be more interesting here: "Dev image" Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPharo'; load. ((Smalltalk at: #ConfigurationOfPharo) project lastVersion) perform: #silently: with: true; perform: #load. And even more, what about loading the baseline directly? cheers mariano On Mon, Dec 20, 2010 at 8:45 AM, Marcus Denker <marcus.denker(a)inria.fr>wrote: > > On Dec 20, 2010, at 4:21 AM, Guillermo Polito wrote: > > Marcus, > > How are we building 1.2 dev?

In other words, how would I modify an object after it's already been created? Hello there are plenty of ways to do that but I think that this is not what you want to do. Tell us what you are trying to achieve? Did you read smalltalk by example from my web page? There is a chapter on object creation and instantiation. Stef > > Thanks, > Elliot >
