[ANN] DBPedia: Query Wikipedia from Pharo
by HernÃ¡n Morales Durand March 2, 2014

March 2, 2014

I have uploaded a new configuration so you can query the english Wikipedia dataset from Pharo 3 using SPARQL. Some examples follow: 1) Retrieve in JSON movies from the beautiful Julianne Moore: | jsonResults | jsonResults := DBPediaSearch new setJsonFormat; timeout: 5000; query: 'SELECT DISTINCT ?filmName WHERE { ?film foaf:name ?filmName . ?film dbpedia-owl:starring ?actress . ?actress foaf:name ?name. FILTER(contains(?name, "Julianne")) FILTER(contains(?name, "Moore")) }'; execute To actually get only the titles using NeoJSON: ((((NeoJSONReader fromString: jsonResults) at: #results) at: #bindings) collect: [ : entry | entry at: #filmName ]) collect: [ : movie | movie at: #value ] 2) Retrieve in XML which genre plays those crazy Dream Theater guys : DBPediaSearch new setXmlFormat; setDebugOn; timeout: 5000; query: 'SELECT DISTINCT ?genreLabel WHERE { ?resource dbpprop:genre ?genre. ?resource rdfs:label "Dream Theater"@en. ?genre rdfs:label ?genreLabel FILTER (lang(?genreLabel)="en") } LIMIT 100'; execute More examples are available in DBPediaSearch class side. You can install it from the Configuration Browser. If you want to contribute, just ask me and you will be added as contributor. Best regards, HernÃ¡n

Question on FUEL & Simple Persistence

Google for it. I would recommend: http://www.pharocasts.com/2010/04/sandstonedb-simple-activerecord-style.html Just open the config browser in a fresh Pharo 3.0, click on "Tools" -> "Configuration Browser" and load SimplePersistence. Then implement a subclass of SpFileDatabase for your custom simple persistence as in the tutorials. Bye T.

Question on FUEL & Simple Persistence
by nacho March 1, 2014

March 1, 2014

Hi there, When I try to install FUEL in a fresh Pharo 3.0 (latest) image, I get the following warning: "This package depends on the following classes: Debugger You must resolve these dependencies before you will be able to load these definitions: encodeDebugInformationOn: serializeTestFailureContext:toFileNamed: serializeStack Select Proceed to continue, or close this window to cancel the operation. " Will this prevent FUEL to work ok? Now going to Simple Persistence, reading through the comments it seems that depends on FUEL, isn't it? Are there any tutorial or example using SP? Thanks in advance! Nacho ----- Nacho Smalltalker apprentice.

Spec problem creating dynamci UIs
by kmo March 1, 2014

March 1, 2014

I'm probably doing this all wrong, but I have a problem creating a dynamic UI with Spec. I want a small window which shows more information when a /Show more details/ button is clicked. Here's an example. <http://forum.world.st/file/n4747139/PharoScreenshot.6.png> when I click /Show More/ I want something like this (a bigger window with more fields): <http://forum.world.st/file/n4747139/PharoScreenshot.8.png> But when I change the Spec layout the window size remains the same as it was set in /initialExtent/ - so it does not display properly with the extra fields. <http://forum.world.st/file/n4747139/PharoScreenshot.7.png> I can't find any way of rebuilding the window so that it shows the bigger layout properly. Here's the spec for the basic window: *basicSpec* <spec: #default> |row1| row1 := SpecLayout composed newRow: [ :row | row add: #label1; add: #field1 ] height: self inputTextHeight; yourself. ^SpecLayout composed newColumn:[:column| column add:row1; addSplitter; add:#btnMode height: self toolbarHeight ; addSplitter]. Here's the spec for the detailed window: *detailedSpec* <spec> |row2 row3| row2 := SpecLayout composed newRow: [ :row | row add: #label2; add: #field2 ] height: self inputTextHeight ; yourself. row3 := SpecLayout composed newRow: [ :row | row add: #label3; add: #field3 ] height: self inputTextHeight ; yourself. ^SpecLayout composed newColumn: [ :column | column add: self basicSpec; add: row2; add:row3 ]; yourself. Here's the code that switches Spec layouts: *initializePresenter* super initializePresenter. btnMode action: [ self needRebuild: false. self label1 needRebuild: false. self field1 needRebuild: false. self btnMode needRebuild: false. self buildWithSpecLayout: self class detailedSpec. ] Is this a problem in Spec or just me being stupid? -- View this message in context: http://forum.world.st/Spec-problem-creating-dynamci-UIs-tp4747139.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Multiple Browsers
by Thomas Worthington March 1, 2014

March 1, 2014

Is it expected that two browsers open on the same class don't reflect the same state if one of them is used to edit the class? I'm sure this used to work, although I might be getting mixed up with Emacs. TW

Snippet for demo - being in control moving the Pharo logo
by btc＠openinworld.com March 1, 2014

March 1, 2014

As a general rule, people feel more confident about systems they can control. So I was thinking this might be a good snippet for demos to give that sense of control. "Evaluate one line at a time." logo := ActiveWorld submorphs last. logo center: ActiveWorld center. logo top: 0. cheers -ben

[ANN] Fuel 1.9.3
by Max Leske March 1, 2014

March 1, 2014

Dear fellow Smalltalkers Mariano, Martin and myself are happy to announce Fuel version 1.9.3 which includes the follwing changes to 1.9 (1.9.1 and 1.9.2 were never officially announced): - (feature) the #fuelReplacement selector offers the ability to statically replace an object (e.g. with nil) during analysis. This can lead to significantly smaller graphs and improved speed when serializing large graphs - (feature) serialize the same graph that was analyzed instead of retrazing the graph during serialization. This prevents changes in the graph from happening between analysis and serialization - (change) store source when serializing CompiledMethod objects. Needed because Opal does not allow decompilation - (fix) migrate variables across hierarchy - (feature) Object>>serializeToFileNamed: shortcut for serializing arbitrary objects - (fix) better compression for LargeNegativeIntegers (https://pharo.fogbugz.com/f/cases/12052/Fuel-could-store-LargeNegativeInteg…) Pharo30 already includes most of these changes (integration request: https://pharo.fogbugz.com/f/cases/13000/Integrate-Fuel-1-9-3) This release runs with: - Pharo: 1.1.1, 1.1.2, 1.2, 1.2.2, 1.3, 1.4, 2.0, 3.0 - Squeak: 4.1, 4.2, 4.3, 4.4, 4.5 The documentation is not up to date yet but we will remedy that situatoin within the next couple of days (http://rmod.lille.inria.fr/web/pier/software/Fuel) If you encounter any bugs or have suggestions, please contact us on the Fuel mailing list (http://lists.gforge.inria.fr/cgi-bin/mailman/roster/pharo-fuel) or create a new issue in our bug tracker (https://code.google.com/p/fuel/) We want to thank everyone who contributed to this release (by keyboard or opinion) and also all of those people who actively use Fuel. Cheers, Max
