[Pharo-project] Morph's #flags instVar
by Bernat Romagosa Dec. 1, 2011

Dec. 1, 2011

Hi list, In order to get Scat to be able to import Scratch projects, we'd need to add the 'flags' instVar to Morph, but whenever we try an error is triggered. Is there a reason for this behaviour? How can we get to add this variable? Thanks! -- Bernat Romagosa

[Pharo-project] Windows disappear in saved image on startup
by Larry Kellogg Nov. 30, 2011

Nov. 30, 2011

Hello, So, I have saved some Pharo 1.0 images, Pharo-1.8.image, for example, that contains a lot of changes that I have made, and packages that I have loaded. Now, when I bring up one of my saved images, I see all the windows the way they were for about three seconds, and then they all disappear. The image is still running but has none of the code I loaded. I tried to interrupt the image in startup (Command . on my Mac) but have been unsuccessful. Is there any way I can fix this problem? I have seven images that all display the same problem. I'm on Pharo 1.0 and running in an Amazon EC2 micro instance.

[Pharo-project] RB API
by Sean P. DeNigris Nov. 26, 2011

Nov. 26, 2011

Is there any documentation on using AST & RB? I didn't find anything enlightening via google, the tests, or the class/method comments. In trying to replace all calls to #deprecate: and #deprecate:in: to #deprecate:on:in: (Issue 4718), it took me hours to step through OB's refactoring and learn the syntax. In case anyone else can benefit, I eventually ended up with: RBParseTreeRewriter new replace: '``@object deprecated: ``@arg1 ' with: '``@object deprecated: ``@arg1 on:(''', dateString, ''') in:(''Pharo', versionNumber asString, ''')'.

[Pharo-project] Unsubscribing for Announcements
by Sean P. DeNigris Nov. 18, 2011

Nov. 18, 2011

I really like Announcements! It's so much easier to update complex GUIs when you can pass state :) I hit one glitch when unsubscribing... The CollaborActive book suggests unsubscribing in #delete. For complex UIs, this doesn't seem to work because #delete is only called for the one morph that was deleted, not for its submorphs (which may need to unsubscribe). I tried this: MyMorph>>delete super delete. "Must come first. Deleting a submorph before self = emergency evaluator" aSubmorphThatNeedsToUnsubscribe delete. SubmorphMentionedAbove>>delete self inventory announcer unsubscribe: self. super delete. But it seems like a lot of work and coupling. Is there no hook that is guaranteed to be called when a morph is going away - i.e. it or a morph in the owner chain is being deleted? Thanks.

[Pharo-project] keymappings question
by Tudor Girba Nov. 4, 2011

Nov. 4, 2011

Hi, I wanted to play with Keymappings, but I got stuck right at the start :). I have two problems: 1. I would like to add a simple shortcut (e.g., "$o command") to a text morph instance. So I have: textMorph := TextMorph new contents: 'abcdefgh'. "what is the magic invocation here ?" textMorph openInWindow The question is what should I write in the second line? 2. I would like to disable existing shortcuts from the text morph. How should I do that? Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

[Pharo-project] Comment Syntax
by Sean P. DeNigris Nov. 3, 2011

Nov. 3, 2011

Would it be difficult/valuable to create an alternate comment syntax? I often find myself wanting to comment a large block itself containing comments. It would be nice to have something like C++'s /* */. I feel like this may have been brought up before, but couldn't find it searching the lists.

[Pharo-project] Issue tracker states
by Marcus Denker Nov. 3, 2011

Nov. 3, 2011

Hi, We started to improve the states defined in the tracker... this now has: FixToInclude = QA has verified that the fix worked, needs to be integrated FixReviewNeeded = Code is there, but a review is needed NoSourcesAvailable = fix proposed, but machine readable code missing Workneeded = Next action is defined but not yet completed NextActionNeeded = What is the next action? Accepted = Problem reproduced / Need acknowledged New = Nobody looked at this yet OnHold = We will come back later to this issue, no action possible now The issue tracker by default sorts the items to show the ones on top that have progressed the most: http://code.google.com/p/pharo/issues/list The idea is that the "FixToInclude" status should be integrated very quickly (within a day), later maybe even automatically.
