[Pharo-project] SystemTracer
by Benjamin March 15, 2012

March 15, 2012

Hello guys, for one of my projects, I'm trying to use SystemTracer to create anew image, but it appears that it doesn't work on Pharo ... I can create a new image, but I can't open it. I've tried with an older VM (Squeak 3.8.18beta1U), but it's the same ... Did someone already have this problem ? Does someone have a solution ? Thanks in advance, Ben

[Pharo-project] startup errors
by Camillo Bruni Jan. 16, 2012

Jan. 16, 2012

While working on Coral we encountered a rather annoying behavior of pharo images when starting up. We wanted to check if we can debug the CoralScriptLoader, but of corse since this happens at image startup time this is not a good ideaâ¦ HOWEVER we were no longer able to run the image as it immediately crashes during the startup. Now I wonder if it would make sense to add a couple of on:do: in SmalltalkImage >> snapshot:anQuit: to collect the errors of all the startup scripts and then only show them after all other startupListItems are processed. All in all the behavior would not much differ from what is going on right now, but would prevent stupid users like me from losing a whole image. camillo

[Pharo-project] Send a notification
by Alexandre Bergel Dec. 2, 2011

Dec. 2, 2011

Hi! Together with Ivan we have been looking for an easy way to send notifications. We first thought about sending email directly from Pharo, but apparently it is not easy to send email. Anyone has experience with this? We then thought about emitting twitts, but there is a need to authorize the client. Anyone has experience? Maybe producing a RSS could do the thing? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[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] 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.
