[Pharo-project] ProfStefBrowser, a GUI for ProfStef

by Danny Chan

Hi! Some of you know, that I made my first dabblings in the Smalltalk world in the last weeks by writing a GUI for ProfStef. The result so far can now be found in the ProfStef repository. There is no Metacello configuration, because I don't know how to make one. Load ProfStef-Core-DannyChan.8 and ProfStefBrowser-DannyChan.18 and start with 'ProfStefBrowser go'. I've implemented some navigation buttons and some buttons to edit the tutorial in the browser. The idea is that people can annotate the tutorials on the fly and may even be able to submit their changes as improvement requests directly from the browser. It would be nice to have some buttons to remove tutorials and lessons as well, but I don't know how to remove classes and methods programmatically. And of course the GUI could have a better look. Have fun, Danny

Re: [Pharo-project] Metacello - the missing information??

Ok, now I think I got what you meant with your question. This question is difficult to answer as it doesn't depends on Metacello. If you want to know which version exactly to load of a particular project, then you need to know about that project or ask the developers/maintainers. It is not a Metacello responsibility. If the person who writes the Configuration is cool, it will put the whole changes/changelog in the #description: of the version method. So that you can at least read it. On the other hand, there are also the blessings. For example, if you are just a user, I would download the last stable release. You can choose also the last beta, or whatever. If you are a developer, you may want to download the latest, even if it is in development. For all these cases, Metacello helps you with methods like lastVersion, etc. Finally, as I said, it doesn't depends too much in the tool. The same question you ask, apply to Universes, SqueakMap or whatever. In all of them you have different versions. And which version to load depends on the project and on the user (what do you want to do with it).

If that is in fact how things can work, there should be an abstract super class for all configurations (or at least a trait they all use to avoid duplicate code) and a method that loads the baseline. ProfStef would be a lot more useful if it made use of Polymorph: a table of contents in a left pane, select an item and the righ pane shows the content, actions replaced with buttons rather than forcing a lot of right-clicking. To the extent that those things are difficult, we need easy-to-use tree models. From what I have been able to figure out of the tutorial, a wiki page would be more helpful and more likely to be read. If you "force" loading of code, then there should be some benefit in the form of interaction. Danny Chan has written ProfStefBrowser (in the same repository as ProfStef) which has both browsing and interactive (ProfStef next) capabilities. Tudor Girba has also written a proof-of-concept using Glamour: Gofer new squeaksource: 'glamoroust'; package: 'ConfigurationOfGlamoroust'; load. (Smalltalk at: #ConfigurationOfGlamoroust) perform: #loadDefault. And then: GTProfStef open (You spawn the new lesson by command+o) Cheers Laurent Laffont My question stands.

[Pharo-project] Transparent World

by Fernando olivero

The last time i tried this, I found out that the LinuxVM is the only one that would accept transparency in the world. Just try out the HoleLW widget in the CUIS image . It does not work with windows or mac vms. John, is this correct for the Mac VM's?

Would'nt it be possible to set the background color to transparent so that you could have squeak windows directly on the desktop?

It seems to work well. A list is opened in a second whatever the number of items. the drawback (a serious one for very long list) is the scrolling because rows are recomputed when they become visible. try it with LazyClassListExample new openOn: Object (for 1.0, get it from www.squeaksource.com/Momo10) So maybe an example to start with ....
