Re: [Pharo-project] [ANN] Alternative view of a system browser

Hi, nice work. Looking forward to play with it. Is it similar to the Newspeak browser? Where methods expand in place.

[Pharo-project] TextMorph: how to change its bounds/extent?
by Gareth Cox July 24, 2012

July 24, 2012

Hi All The default behaviour of a TextMorph is for it to grow down as you enter text. How can I change that behaviour so that the TextMorph grows both up AND down as I enter text? Kind Regards Dusty

[Pharo-project] Change in MCCacheRepository that affects Metacello loading
by Mariano Martinez Peck July 24, 2012

July 24, 2012

Hi Dale. http://code.google.com/p/pharo/issues/detail?id=6405 renames MCCacheRepository #default to #uniqueInstance. Therefore, to be able to bootstrap Metacello we need to change: ConfigurationOfMetacello class >> bootstrapPackage: aString from: aPath | repository version | repository := (*MCCacheRepository uniqueInstance* includesVersionNamed: aString) ifTrue: [*MCCacheRepository uniqueInstance*] ifFalse: [MCHttpRepository location: aPath user: '' password: '']. repository versionReaderForFileNamed: aString , '.mcz' do: [:reader | version := reader version. version load. version workingCopy repositoryGroup addRepository: repository] I could commit, but I don't want to break Metacello loading in other images and I don't know how do you handle these cases. Thanks, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] athens for strikefonts

Hi Igor, I just wanted to ask: is the little fix of having Athens work with StrikeFont still on the roadmap :)? As I mentioned before, this would make the adoption easier, because we can switch the Athens even with the regular CogVMs. Cheers, Doru -- www.tudorgirba.com "It's not what we do that matters most, it's how we do it."
