[Pharo-project] CategorySaver
by Sebastian Nozzi Nov. 13, 2012

Nov. 13, 2012

Dear Pharo Community, I would like to share with you the work of my past weekend, and announce "CategorySaver". It is a simple utility to periodically save (file-out) a list of categories given (wildcards accepted). You can find it here: http://smalltalkhub.com/#!/~sebnozzi/CategorySaver And invoke it like this: CategorySaverPanel new openInWorld What motivated me to do this was loosing hours of work after image "hang-ups", without having saved before. In those cases I thought that it would be cool to have some kind of background process, that at least saved some recent version of the code I was working on. But only now I got myself to write it. Hopefully you are not like me, you know what you are doing, the VM never hangs on you, and don't need this utility ;-) For all others I hope you might find it helpful. Best regards, Sebastian P.S. I am kind of a Smalltlak newbie. So if you find things to improve in the code, I am glad about any tip / critique. P.S. 2 -- I was amazed at how easy it was to code the UI! UI programming in Squeak/Pharo was always an area where I thought must be incredible complicated, but thanks to UITheme's builder (Polymorph?) it's a breeze. Good work! P.S. 3 -- Did I have to manually add [ANN] to the subject? My apologies in this case. Also my apologies if this kind of mails correspond to only one of the lists.

[Pharo-project] Is the one-click image *really* self contained?
by roberto.minelli＠usi.ch Nov. 13, 2012

Nov. 13, 2012

Hi all, Since this morning every time I open Pharo 2.0 an error pops out. Here's the full trace: Parser>>notify:at: Parser>>expected: Parser>>braceExpression Parser>>primaryExpression Parser>>messagePart:repeat: Parser>>expression Parser>>statements:innerBlock:blockNode: Parser>>statements:innerBlock: Parser>>method:context: Parser>>parse:class:category:noPattern:context:notifying:ifFail: in Block: [methNode := self method: noPattern context: ctxt]...etc... BlockClosure>>on:do: Parser>>parse:class:category:noPattern:context:notifying:ifFail: Compiler>>translate:noPattern:ifFail: Compiler>>evaluate:in:to:notifying:ifFail:logged: Compiler class>>evaluate:for:notifying:logged: Compiler class>>evaluate:for:logged: Compiler class>>evaluate:logged: DoItDeclaration>>import CodeImporter>>evaluateDeclarations in Block: [:decl | value := decl import] OrderedCollection>>do: CodeImporter>>evaluateDeclarations CodeImporter class>>evaluateFileStream: FileReference(AbstractFileReference)>>fileIn in Block: [:stream | CodeImporter evaluateFileStream: stream...etc... FileReference(AbstractFileReference)>>readStreamDo: in Block: [aBlock value: stream] BlockClosure>>ensure: FileReference(AbstractFileReference)>>readStreamDo: FileReference(AbstractFileReference)>>fileIn StartupLoader>>loadPreferences in Block: [:file | file fileIn] OrderedCollection>>do: StartupLoader>>loadPreferences So, I downloaded a new one-click image, believing the error would disappear since I supposed that everything is self contained butâ¦ this is not the case: In every new Pharo one-click image I have this errorâ¦ Do you have any intuition on that? Cheers, Roberto

[Pharo-project] NB Capabilities
by Jimmie Houchin Nov. 12, 2012

Nov. 12, 2012

I am developing an application which needs to access a proprietary business API to access data from their servers. Currently because I don't know how to do that from within Pharo, I have been using Python/COM. But that API is deprecated and expires soon. Now I have to move to an app which accesses via either a C/C++ app which accesses a DLL, a .NET library or a Java jar. There are a number of objects that have to be created from the dll/jar, and a number of interfaces which have to be implemented from the dll/jar. Presently I am studying Clojure in order to work from the Java side. I do not know Clojure or Java. If I could learn sufficient C and do this with NB in Pharo, that would be very nice. I have never done anything like what NB does, so I do not know what all it does or can do. Can Pharo implement the interfaces provided in the DLL in the Smalltalk side? Or would the interfaces have to be implemented on the C side and then Pharo access the objects? Any advise greatly appreciated. Thanks. Jimmie

[Pharo-project] selectors vs. localSelectors in condenseChanges
by Pavel Krivanek Nov. 12, 2012

Nov. 12, 2012

Hi, in the condenseChanges method the message moveChangesTo: is heavily called. And this method exports changes for all selectors of the behavior. But I suppose that we want to process only local selectors here. Can some traits guy confirm that we should replace call of the message #selectors with #localSelectors here? Cheers -- Pavel

I've moved the MongoTalk project to SmalltalkHub: http://www.smalltalkhub.com/#!/~francois/MongoTalk/ The original repo is still available but please use the new one. I don't know how to put a repo in global read/write on Smalltalkhub (is it possible?)

[Pharo-project] TimeProfiler and primitives
by Mariano Martinez Peck Nov. 11, 2012

Nov. 11, 2012

Hi guys. I remember some improvements made to TimeProfiler regarding primitives. I am profiling something which does a lot of primitive calls, and the TimeProfiler is quite dumb. It shows almost everything as #finalizationProcess but I know that the time is not actually spent there. I remember someone that fixed this (maybe Eliot telling me that on Teleplace?). Anyway, any help is appreciated. Thanks, -- Mariano http://marianopeck.wordpress.com
