Please note that there are about 10 tests related to dictionaries that fail now.

Re: [Pharo-project] Shall we forbid updating?

by Adrian Lienhard

It would be interesting to understand what exactly the problem is. Has anybody looked into it? If it is hard to fix, we should disable the update function. When we create an update, we (or at least I) only test with the core image.

Re: [Pharo-project] KnownLands: a Class dependency explorer

by David Goehrig

Thanks Alexandre! This actually works in one of my images, after a few tweaks. I finally figured out what was causing the issue and it had to do with my old image had a half installed version of Mondrian that couldn't unload. That said, Mondrian is conceptually so far away from what I'm aiming for I'm not likely to ever use it :) Dave On Mon, Jul 20, 2009 at 10:01 AM, Alexandre Bergel <alexandre(a)bergel.eu>wrote: > > Doru spent already a lot of effort. > > me as well. > > Mondrian works on Pharo.

Re: [Pharo-project] Shall we forbid updating?

by John E.

I just tried it last week and it failed horribly, and yet tried it today and it worked great. I'm new to Pharo and tried it as I was used to updating Squeak frequently. If it's going to work in the future I'd say leave it. If it's part of core only it would be nice to not see it other builds. - John Damien Cassou wrote: > > > in the Pharo images I produce, there is a System->Update that never > works.

[Pharo-project] Housekeeping of objects and variables (was: Where declared global reside... how can they be removed?)

by John E.

I appreciate all the feedback. I learned a lot about the SmallTalk Dictionary this way. "Smalltalk removeKey: #MyGlobal" worked great of course, however I'm now just using "reset variables" in the Shout Workspace window. Even though the latter will clear them all, is there a clear path towards "show me all the variables I've made in the Workspace" ? I realize building full objects would be more correct for a final project, however the tutorials (and my own tinkering) usually find me creating quick things in a Workspace to experiment and I'm just making sure I know and understand how to clean it up later. Will Pharo possibly add any visual behavior to keep track of "floating" objects or add a "variables" window for workspaces? -- John John E. wrote: > > For most tutorials (I'm using squeak tutorials), one does a lot of > work in a workspace. > > If I make a new global variable such as: > > MySquare := Morph new > > ...once I define "MySquare" as a global variable I know I can send it > many messages like: > > MySquare openInWorld > MySquare color: Color yellow > > When I'm done and I close the workspace, save the image and save the > image.

[Pharo-project] Creating graphics and UI in Pharo

by John Escobedo

Thanks everyone for the help with clearing the Smalltalk Dictionary variables (and best practices to avoid setting them). Since about Squeak 2.x I'd discovered smalltalk and have been learning as I go. One of the most confusing aspects is that there is very old documentation that still holds up well (the book "Inside Smalltalk") mixed with documentation that is only a few years old yet outdated. One area where this has given me the hardest time is trying to learn how to create interfaces and graphics for my programs. I know morphic has gone through and is going through many changes, but what is its future with Pharo and what would be the "best practices" for making images and UI for programs I am writing? - John

Yes, your example works fine. I appreciate your work. I am not familiar with scamper and just want to try it as easily as I can.

[Pharo-project] Shall we forbid updating?

by Damien Cassou

Hi, in the Pharo images I produce, there is a System->Update that never works. A lot of people are confused by it and don't know it only works on the core. Shall we remove this item from the menu?
