moving moose to pharo 3.0
by Tudor Girba Nov. 4, 2013

Nov. 4, 2013

Hi, We essentially finished moving Moose to Pharo 3.0 (we still have 6 yellow tests but they needed attention anyway). It took about 4 people looking into issues for a total probably around 2 man-days of effort. The largest impediment was actually SmalltalkHub being down for one day :). What posed problems: - RB visitor now has correct visit* methods instead of accept* methods. The deprecation messages helped quite a bit. This meant (1) that we had to rename in our visitors the methods, and (2) that we had to change the old accept* messages. - RB nodes do not answer to #isLiteral anymore. Instead, they answer correctly to #isLiteralNode so that to avoid confusion with Object>>#isLiteral. This is good, and this meant that we had to hunt all #isLiteral usages in Moose. - Categories are no longer mapped on RPackages through 1-to-1. This is also good because it is an important step in Pharo. Although originally we said we want to keep 1-to-1, this is probably a better solution now. For Moose, this meant that some of our older tests setup had to be modified a bit to rely on RPackage only. - Some Morphs rely now on Announcements, and this had a little impact on the assumptions we make when we suspend announcements (to avoid infinite loops) that are being sent between Morphic and Glamour. We fixed this in Glamour. - In FileSystem #ensureDirectory was renamed to #ensureCreateDirectory without a deprecation. For this one, we should add a deprecation for the old method. - flatCollect had a conflicting behavior in Pharo. We are now integrating the Moose version so that it returns the same species. - The new SpecDebugger expects the registered Inspector to be based on Spec, and this causes problems with the GTInspector. This problem still has to be fixed in Pharo. All in all, we encountered no significant problems and the problems we faced came from deep into Pharo. So, if your code is not relying directly on RB, RPackage or the Debugger, you are likely to have a smooth transition. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Building a simple UI with Spec. Problem with menus.
by nacho Nov. 3, 2013

Nov. 3, 2013

Hi, this is my first post in the Pharo group. I'm developing a simple Text Editor with some nice features as a way to understand how Spec works. It seems that Spec will be the default UI framework from Pharo 3 onwards, I know it's changing and evolving but I'll take the risk. The problem I'm facing is that I'm lost at trying to add a "Save as..." option in the menu. It seems that Spec is still using the Morphic MenuMorph>>ToggleMenuItemMorph but it's not clear to me hoy to add this item. On the other hand, inspecting the ComposableModel class, it seem that in the future this will be done directly in Spec as suggested by the ComposableModel>>addMenuItemsToWindowMenu: But so far that method simply says "do nothing". Any help? Thanks in advance Cheers Nacho -- View this message in context: http://forum.world.st/Building-a-simple-UI-with-Spec-Problem-with-menus-tp4… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I would rather pay for Smalltalkhub than use Github for free.
by MartinW Nov. 3, 2013

Nov. 3, 2013

Just a thought on the discussions about Smalltalkhub beeing down and people would love to use Gibhub instead: I would rather pay for Smalltalkhub than use Github for free. And there is all this talk about building a business with Pharo - why not make a business from Smalltalkhub? The thought of course is that when Smalltalkhub would be a business, itâs makers could spend more time and effort keeping it up and running and adding new features. This may have been quoted a lot but still: "The lesson: People are happy to pay for things that work well. Never be afraid to put a price on something. If you pour your heart into something and make it great, sell it. For real money. Even if there are free options, even if the market is flooded with free. People will pay for things they love.â From: http://37signals.com/svn/posts/2794-how-to-get-good-at-making-money -- View this message in context: http://forum.world.st/I-would-rather-pay-for-Smalltalkhub-than-use-Github-f… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Transforming JPEG Images into Morphs
by Bruce Prior Nov. 2, 2013

Sven wrote: It is trivially easy to open a JPEG (or GIF or PNG) and turn it into a Morph: '/Users/Sven/Desktop/test.jpg' asFileReference readStreamDo: [ :in | (JPEGReadWriter on: in) nextImage asMorph openInWindow ]. I tried this in Pharo 1.4 one-click but got an MNU: 'reset'. It does work, however, in Pharo 3 one-click.

Roassal design question
by Peter H. Meadows Nov. 1, 2013

Nov. 1, 2013

When using ROLightlyHighlightable the color is changed by giving the element to ROBlink which then sends #color: to the element's shape. What is gained by doing it like this? Wouldn't it be simpler for the element itself to be able to set the color of it's shape? (Also couldn't each shape be a subclass of element?)
