[Pharo-project] Scat - Public Release and announcement
by Bernat Romagosa Jan. 17, 2012

Jan. 17, 2012

Hi list, Joan GÃ¼ell and I have been working on Scat -the Scratch port to Pharo- quite a lot recently. We wanted to push it to a point where we could release the first reasonably working version, which we've just managed today. Please take a look at the release announcement<http://code.google.com/p/scat/wiki/PublicRelease> (which should be read in a bit of a humorous tone), in which we explain what's up with the project and what future is left for it. For the tl;dr version, please read: - Many things are working, many aren't, but the state of the project allows us to move into more interesting stuff based on the graphic programming metaphor. - Scat is a time-consuming, brain-smashing, life sucking-project. - We no longer will be maintaining this massive unmaintainable code. - Suddenly: free time for other projects! Cheers everyone! -- Bernat Romagosa.

[Pharo-project] Styling in Inspector
by Guillermo Polito Jan. 17, 2012

Jan. 17, 2012

I added the following method to inspector and styling turned on: shoutAboutToStyle: aPluggableShoutMorphOrView ^ true Should we add it? Also, I've tryed to remove the styling from the PreDebugger window on warning messages by setting it a NullTextStyler and it doesn't work :). I'll continue hacking.

[Pharo-project] loading subclasses of non existing superclasses with Monticello
by Mariano Martinez Peck Jan. 17, 2012

Jan. 17, 2012

Hi guys. I noticed that when loading a package with classes whose superclasses are not present in the image, and the Monticello popup appears, then those subclasses are not loaded at all. I think I remember they were loaded anyway as a subclass from an obsolete class. But I have just checked in pharo 1.2, 1.3 and 1.4 and the subclasses are not loaded at all :( So...I am just crazy or it used to be that way and then it changed? thanks -- Mariano http://marianopeck.wordpress.com

[Pharo-project] reading *exactly* n bytes from socket
by Max Leske Jan. 16, 2012

Jan. 16, 2012

Hey guys I'm having a problem with Socket / SocketStream. When I know that the next packet of data from the server is going to be 10'000 bytes I want to ask the socket for exactly 10'000 bytes of data (I don't care how long it takes). However, the comments in the Socket class suggest that the buffer might not be filled entirely when the message answers. As a consequence, my code fails because the ByteArray sometimes has a number of zero bytes at the end which obviously wasn't expected. I also tried to use SocketStream to get around this problem but wasn't successful. Am I supposed to handle this case myself or did I overlook something? Cheers, Max

It presets some dictionary structures as described at [1a] 8.1.

[Pharo-project] Monticello mirror not installing in Pharo 1.4
by Guillermo Polito Jan. 16, 2012

Jan. 16, 2012

First, it needs ObjectAsMethodWrapper, which is not any more in the 1.4 image :) Second, ObjectAsMethodWrapper uses MethodReference, causing an infinite recursion when installing the mirror. I fixed this changing the method *#on:selector: *by on: aClass selector: aSelector ^self on: (RGMethodDefinition class: aClass selector: aSelector) Guille

hi guys I'm playing with Hazeltracer and I generate 3.4 mb image with Opal. Now I have one single process that one :) and I do not understand because the following code work: I get 33 in the file. No stack dump. freshProcessWorkingWithOpalLoaded ^ [ |file| [ file := StandardFileStream fileNamed: 'loglog.txt'. file nextPutAll: 'Start'. [ file nextPutAll: ((OCClosureCompiler new compile: 'foo ^ 33.' in: Object classified: nil notifying: nil ifFail: []) generate valueWithReceiver: Object new arguments: #()) asString] on: Error do: [:ex | ex outer errorReportOn: file]. ] ensure: [file close]. [true] whileTrue: [Beeper primitiveBeep. ]] newProcess while this one does not :). I do not get the influence of the on:do: freshProcessWorkingWithOpalLoaded ^ [ |file| [ file := StandardFileStream fileNamed: 'loglog.txt'. file nextPutAll: 'Start'. file nextPutAll: ((OCClosureCompiler new compile: 'foo ^ 33.' in: Object classified: nil notifying: nil ifFail: []) generate valueWithReceiver: Object new arguments: #()) asString ] ensure: [file close]. [true] whileTrue: [Beeper primitiveBeep. ]] newProcess any idea? Stef
