My image appears for an instant and then crashes. Is there any way to recover from this? Thanks. Sean -- View this message in context: http://forum.world.st/Oops-I-put-a-halt-in-a-startup-method-tp3800163p38001… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

by StÃ©phane Ducasse Feb. 18, 2012

Feb. 18, 2012

Hi guys we have a roadmap for Esteban and we would like to share it with you. We have extra items that we would like to see fixed and we are welcoming your feedback/suggestions. Note this is typically the way we want to work with the consortium in the future: Build an initial roadmap and refine it based on the input of the community. - A website for the consortium registration (esteban is expert on that). - This is important for INRIA and for the visibility of the consortium. We should get new members :) - Integration with SmalltalkHub - Working on fixing bugs! - Debugger fixes - Continuous bug fixing. - Improving release process: faster, more people involved, simpler. - Working on metacello repositories for each distributions (everything is there but missing last bits) - Metacello tools - Automatic release validations - Automatic validation of fixes Now the free items with probably igor involvement - Multiwindowing support - Fully working multithreaded FFI with ***Documentation*** - Filesystem fix and integration - Integration of OPAL - RPackage integration Igor related - Ephemerons - Object format - VM branding - Use of new canvas - Event cleaning So we are waiting for your suggestions.

[Pharo-project] object format of true, false, nil and others...
by StÃ©phane Ducasse Feb. 18, 2012

Feb. 18, 2012

Hi imagine that I want to bootstrap our nice kernel. I will need to somehow create a new nil, true, false, instances of new classes Undefined, True, False. Such instances will then be put on the SpecialObjectArray somehow. Now I can create a dummy object playing such roles and then use SystemTracer to substitute my placeholder with the true nil falseâ¦. or another trick to swap them. Now anybody has other ideas? Stef

[Pharo-project] Now you can use Fuel with FileSystem
by Mariano Martinez Peck Feb. 18, 2012

Feb. 18, 2012

Hi guys. Now you can use FileSystem streams for Fuel. Fuel only needs one small package 'FuelFileSystem' which has just 3 extension methods, and that's all ;) There is also 'FuelFileSystemTests' which let's you run all fuel tests using FS. If you want to do that, change FLSerializationTest >> setUp to send #useFileSystemFileStream rather than #useStandardFileStream and that's all. To install: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFuel'; load. (ConfigurationOfFuel project version: #bleedingEdge) load: 'withFS'. An example: | sourceArray loadedArray serializer stream materializer | sourceArray := Array with: 'a string' with: Transcript with: [ Transcript show: 'a string' ]. "Create a file and serialize on it" stream := (FSLocator imageDirectory / 'example.fuel') writeStream. serializer := FLSerializer newDefault. serializer serialize: sourceArray on: stream. stream close. "Load from the file" stream := (FSLocator imageDirectory / 'example.fuel') readStream. materializer := FLMaterializer newDefault. loadedArray := (materializer materializeFrom: stream) root.

[Pharo-project] a fix to KomServer
by Milan Mimica Feb. 14, 2012

Feb. 14, 2012

oops, looks like I have committed something... I have committed a patch to http://www.squeaksource.com/KomHttpServer I wanted to have it checked by someone first, didn't really think it would let me commit just like that. Sorry for the inconvenience. Anyway, now that it's there someone has to look at it. :) It's not much. The problem was KomServer threw MNO when a request was made with an absolute URL in the HTTP request, which is valid as I read it [1][2]. [1] http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2.1 [2] http://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html#sec5.2 -- Milan Mimica http://sparklet.sf.net

[Pharo-project] Pharo Morphic View Application Framework
by S Krish Feb. 5, 2012

Feb. 5, 2012

http://skrishnamachari.wordpress.com/2012/01/31/pharo-application-framework… Obliged for feedback ... For details and links.. Sharing this little framework that should go some way to ease creating large applications ( currently morphic oriented). AbstractMorphicView subclass: #MyNewView â¦ #createMorphsSpecs ^{ âpanel1â² -> #SomeOtherView. âlabel1â² -> #LabelMorph. âtext1â² -> #PluggableTextMorph. âbutton1â² -> #PluggableButtonMorph. } layoutSpecsArray ^{ âwidgetNameInMorphsDictionaryâ -> { #fractions -> (0 @ 0 corner: 1 @ 0.5). â fractional value 0 to 1 range â #offsets -> (10 @ 10 corner: 0 @ 0). â offsets relative to the fractional position â }. ââ¦ add other widgetspecsâ¦â } Thats it.. you should have a prototype UI neatly laid out.. and then specify: #morphsPrimaryPropertiesSpecs and #morphsSecondaryPropertiesSpecs for full functionality that composes views inside views and scales well. AbstractSimpleMorphicView can make it simpler for TableLayout stuff without requiring #layoutSpecsArray. ..... the main post has other details and links to package...

[Pharo-project] Command Line Interface using FFI
by Guillermo Polito Feb. 3, 2012

Feb. 3, 2012

I've spent a few hours playing with Alien+FFI and I did want to have a Command line interface to play and use as a quick browser. Gofer it squeaksource: 'CLInterface'; package: 'ConfigurationOfCLInterface'; load. ConfigurationOfCLInterface load. To play with it write a script, for example startCLI.st, with the following: *CLInterface start* And then, from the command line CogVM -vm-display-null <image> startCLI.st What it does support? - executes smalltalk expressions - handles the errors and shows them into the stdout (so it does not explode :P) - stores variables as a workspace Since I used standard C functions (fgets and printf only) this should work on every platform from scratch (having a VM with FFI working, of course)... The problems I've ran so far: - blocking FFI blocks the vm. I've not tried yet to use threads through FFI (and I don't know if it works. Does it?). But It should be great to start a headless seaside server with a command line :/. Ok, it's a very simple thing, but it allows to execute a expression from a remote server via ssh without doing much :). Guille
