[Pharo-project] SocketStream>>atEnd
by Igor Stasenko Jan. 15, 2010

Jan. 15, 2010

Hello guys, today, by examining closely the #atEnd implementation , i came to conclision that is can be made as simple as: atEnd ^ self isDataAvailable not Because, take a close look at old implementation: atEnd self isInBufferEmpty ifFalse: [^false]. ----***--- ^self isConnected not and: [self isDataAvailable not] and: isDataAvailable self isInBufferEmpty ifFalse: [^true]. ---***--- ^socket dataAvailable ifFalse: [false] ifTrue: [self receiveDataIfAvailable; isDataAvailable] a Socket>>dataAvailable answers false on closed or invalid socket. You can check it quite simply: (SocketStream openConnectionToHostNamed: 'google.com' port: 80) socket closeAndDestroy dataAvailable (SocketStream openConnectionToHostNamed: 'google.com' port: 80) close socket dataAvailable Socket new dataAvailable => all 3 answer false Therefore, a complex logic in #atEnd, could be simplified. Please, try to find a flaw in my conclusions. I think there's not. But 2 (or more) heads always better than 1. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Time for a new election in squeak.org soon
by GÃ¶ran Krampe Jan. 14, 2010

Jan. 14, 2010

Hi all! This is a post to the Squeak election-list, but I am CCing to squeak-dev AND pharo (just to keep you guys in the loop). NOTE: If you reply to this post, no need to harass the pharo list with the actual thread, let's keep that on squeak-dev/election-list. Ken Causey wrote (on the election list): > It's coming up another Squeak Oversight Board election season. > There's a bit of time yet but if you have any thoughts of making any > significant changes this year, it's time to get started on that. Yeah, I know. :) I haven't had the energy to get it all going yet... Community check: - Are there any "ideas" about changes to the election process? - Are we satisfied with how it all works or are there things we need to address? - Does the SOB have any thoughts on it (although of course partial to the issue)? This was last year: http://wiki.squeak.org/squeak/6116 ...the first post usually explains how it works: http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-February/133840… regards GÃ¶ran PS. I still consider Pharo and Squeak to be highly intertwined communities so input from Pharons/Pharaos/Pharooosies/p... ah, what are you guys called? :) ...is also welcome.

[Pharo-project] Comments on Metacello and ConfigurationOfExternalWebBrowser
by Torsten Bergmann Jan. 14, 2010

Jan. 14, 2010

>Two little remarks of the conf: you are using for FFI '1.0-baseline', not a >version, this means that it will ALWAYS bring the latest version (maybe >unstable). That's why I always try to put a particular version that I know >is stable. Thought about that again and looked at other examples. Now the baseline of ExternalWebbrowser depends on a baseline of FFI. And the version itself uses the version. See ConfiguratonOfExternalWebBrowser-tbn-5.mcz This is similar to what Dale did in the seaside 3.0 config with grease and follows the rules from #lesson11Blessing: "Since the latest #baseline version should reflect the most up-to-date project structure, ... should load the absolute bleeding edge of the project." >Come on!!! That's not an excuse ;) Have access now - typos in the tutorial are fixed. Included in 1.0-beta.20 of metacello conf. Just run "ConfigurationOfMetacello loadLatestPackages" Bye T. -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

[Pharo-project] [ANN] JQueryWidgetbox and Metacello
by Torsten Bergmann Jan. 14, 2010

Jan. 14, 2010

Hi, the JQuery Widget box project now switched to Metacello: - there is now a "ConfigurationOfJQueryWidgetBox" project/class in htp://squeaksource.com/MetacelloRepository - this configuration includes a baseline and a first version 1.0 - the old "loader" project (JQWidgetBox-Loader) - in http://squeaksource.com/JQueryWidgetBox can be used as before - it now internally uses Metacello How to get started: =================== We assume a clean image - for instance the latest pharo core (PharoCore-1.0-10506rc1.image) - without any Seaside here: A. THE OLD WAY -------------- To get the old loader (which is now ALWAYS loading the latest version from the metacello configuration) evaluate: Gofer new squeaksource: 'JQueryWidgetBox'; package: 'JQWidgetBox-Loader'; load. Answer yes - and see how Seaside 3.0 and the widget project is loaded. When finished start a webserver through WAKom startOn: 9092 and point browser to http://localhost:9092/browse/jquery-widgets This is working as before - but not as flexible as with Metacello. B. THE NEW (METACELLO) WAY -------------------------- First you need to load the Metacello configuration for the project Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfJQueryWidgetBox'; load. You can now decide to get: ========================== B.1. the latest version (including all tests, examples and widgets - similar to the old loader in A.) (Smalltalk at: #ConfigurationOfJQueryWidgetBox) loadLatestVersion B.2. a specific version (currently there is only one) ((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.0') load B.3. load a specific widget for your seaside project from Widget box version 1.0 (without tests and examples) ((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.0') load: 'JQWidgetBox-Growl-Core' B.4. load a specific widget for your seaside project from Widget box version 1.0 (including tests and examples) ((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.0') load: 'JQWidgetBox-Growl-Dev' B.5. load three widgets for your seaside project from Widget box version 1.0 (two with tests/examples and the first without tests/examples) ((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.0') load: #('JQWidgetBox-Growl-Core' 'JQWidgetBox-Calculator-Dev' 'JQWidgetBox-Calculator-Dev') B.6. load all the latest packages from the 1.0 baseline - with all widgets, respective tests and examples to do development ((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.0-baseline') load If an example for a widget is loaded it will automatically appear at http://localhost:9092/browse/jquery-widgets Things to note: =============== If one wraps and adds new jquery widgets to the widget box project he must now add it in the metacello configuration. The old loader project should stay unchanged and remains for compatibility reasons. Have fun, T. -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT!

Hi marcus jannik and me got fun and fixed some cycles. Here are some extra notes I took - PreferenceBrowserMorph and friends should be removed. - MethodReference could be closer to CompiledMethod (to avoid cycle with tools when in fact people just wanted to report aCompiled method list and return a methodReference list). - Services -> split into Services-Morphic and Services-Core -> but services should be removed for now - Symbol could has its own scanning function (isLiteralSymbol) to avoid to depend on Scanner - URL should be replaced by URI - WordArrayForSegment -> ImageSegment - FilePackage -> Tools - TextDiffBuilder -> in its own package.
