neo json and valueSchema for integer attributes ...
by itlists＠schrievkrom.de March 24, 2014

March 24, 2014

I have a class with an instance attribute "x" and this one contains an integer value. No when exporting this to json I want to write a string instead of this number to the json string ... neoJsonMapping: mapper mapper for: self do: [ :mapping | (mapping mapInstVar: #x to: 'x') valueSchema: #AsString. ]. mapper for: #AsString customDo: [ :mapping | mapping encoder: [ :anInteger | x asString ]. mapping decoder: [ :aString | ... ] ]. But whatever I do ... only numbers are written out ... and yes of course I could add additional accessors doing the conversion. -- Marten Feldtmann

NeoJSON and inheritance
by Norbert Hartl March 22, 2014

March 22, 2014

How is inheritance supposed to work in NeoJSON? I only figured it out by doing that manually: neoJsonMapping: aMapper super neoJsonMapping: aMapper. (aMapper mappingFor: self) mapInstVar: #longitude; mapInstVar: #latitude. Is there a better way to do? Norbert

index of element matching block
by Norbert Hartl March 4, 2014

March 4, 2014

I just discovered that there is no method like indexOf: aBlock where the index of the element matching the block is returned. What would be the usual way to achieve this functionality? Norbert

Spec question
by Glenn CavarlÃ© March 3, 2014

March 3, 2014

Hi all, i'm new (first post) and my english is very poor so please don't blame me :). I would like to use Spec for display a collection of domain objects and i would like to specify the layout which apply to each items, not just display a String or a Text like "ListModel>>displayBlock:" but a more complexe layout with rows, columns and images within (for example). To illustrate, an equivalent would be the component ListView in Android. I turn to you to know if it's possible to do that with Spec. Thanks, Regards, Glenn ----- Glenn CavarlÃ© -- View this message in context: http://forum.world.st/Spec-question-tp4741608.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Multiple Browsers
by Thomas Worthington 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
