Re: [Pharo-project] Is there a good reason why ifEmpty: and ifNotEmpty: return nil rather than the receiver (as they do in Squeak) when the condition is false?

thanks for reporting can you open a pharo bug entry else there is 80% of chance we will forget.

Re: [Pharo-project] Question: How can I add a items to System Browser Window menu?

by Mariano Martinez Peck

what would be create is to step by step make all menus easily extenesible. Like nowadays with the world menu and pragmas Carla, once I had a similar problem and the only solution was to override that method with a *MyPackage in that method, and add there the menu entried I wanted...this is completly wrong and sucks...but was the only thing I found cheers 2010/8/10 Carla F.

Sean, I didn't read all the thread, but did you know that Metacello let you handle platform specific code? Thus, you can define this in the ConfigurationOFfExternalWebBrowser, and not depend on a class side initialize. cheers mariano On Tue, Aug 10, 2010 at 9:14 AM, Norbert Hartl <norbert(a)hartl.name> wrote: > > On 09.08.2010, at 20:48, Sean P.

I just uploaded the file and thought it would be interesting from today's perspective. As I just uploade the stuff to slideshare, it was easy to pushlish the link. But this is now not that important... if I would have known that it's not that easy to view, I would not have send the link in the first place. The idea is to have the ESUG archive available in more than just slideshare... but everything takes time and I can do things only step by step. And the step right now is slideshare. Doing *anything* with an archive of 14 years of confrences takes a looong time....
