[Pharo-project] Trait methods in Nautilus

We don't show the methods coming from superclasses so I don't see any reason why methods coming from traits should be visible. And yes, I'm aware that trait methods are in the method dictionary of the class, but this is implementation detail :-) -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."

[Pharo-project] SmallHarbour questions
by GermÃ¡n Arduino Feb. 8, 2012

Feb. 8, 2012

Hi: I'm trying to start using SmallHarbour and found several problems or is me that don't know how to do the things: 1. How to delete a folder? (If I create a folder and click on it and then press delete nothing happens). 2. How to delete images and changes files? (If I click in an image it says "file to big to download", but I don't have a place to select it to delete. 3. I uploaded a sample image and somethings start and somethings not and when starts can't reach it on the url (Not found log info still). Some advices about sort of images/apps, etc to upload? TIA. -- ============================================ GermÃ¡n S.

[Pharo-project] Trusting Trust
by Ben Coman Feb. 8, 2012

Feb. 8, 2012

This is slightly paranoid thinking, but considering the long evolution of Smalltalk live images (apparently all the way from the original Xerox PARC ST80 [1] ) in relation to Ken Thompson's "Reflections on Trusting Trust" [2] - are there any mechanisms to prevent trojan code living undetected inside a Smalltalk compiler/decompiler ? Bruce Schneier [3] provides a shorter overview of [2] if that is not to your taste. To what degree might this ever be an issue with Pharo and how might it be mitigated ? cheers, -ben [1] http://lists.squeakfoundation.org/pipermail/squeak-dev/1999-January/011116.… [2] http://www.ece.cmu.edu/~ganger/712.fall02/papers/p761-thompson.pdf [3] http://www.schneier.com/blog/archives/2006/01/countering_trus.html

[Pharo-project] Resource Descriptor Framework
by Ben Coman Feb. 8, 2012

Feb. 8, 2012

Is there much being done with Resource Description Framework in Squeak/Pharo? I have some RDF data files that I need to load for my masters project and am seeking advice on how to approach this. I am only just learning about RDF for the first time. For anyone else interested the best short overview I found so far is [ http://logicerror.com/semanticWeb-webdev ] Apparently it this is a Simplified RDF Syntax as described at [ http://www.langdale.com.au/CIMXML/PSModelExchange.pdf ] A data file looks like like this... <?xml version="1.0" encoding="UTF-8"?> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:cim="http://iec.ch/TC57/2007/CIM-schema-cim12#"> <cim:ACLineSegment rdf:ID="_7814201"> <cim:Conductor.length>95</cim:Conductor.length> <cim:IdentifiedObject.name>AMHE400MARCLINE</cim:IdentifiedObject.name> <cim:ConductingEquipment.BaseVoltage rdf:resource="#_400000302"/> <cim:Equipment.MemberOf_EquipmentContainer rdf:resource="#_487038201"/> </cim:ACLineSegment> The most obvious project on Squeaksource is Rakaiko [a] which says "RDF is an essential part of the new web technologies and a fundamental layer of the semantic Web 2.0 [...] This API, compliant with the W3C RDF specification will allow a developer to handle an RDF graph in its various forms (RDF/XML, N3, abstract graph). In other words, it would be the Squeak equivalent of the Jena Java RDF API." However there has been no activity on Rakaiko since 2007 and there is no apparent documentation. Has anyone used this and/or is this abandoned? Page 20 of "ESUG 2006 Welcome" mentions a "RDF Framework for Smalltalk." Did anything come of this? Alternatively I could fake it and learn just how to parse the XML directly and manually translate it into the class model. (It seems processing an a RDF Schema might be able to automatically create the class definition as well as the instance creation ) There is PetitXML, which however is not included by ConfigurationOfPetitParser.24 loaded on Moose 4.6. What is the status of PetitXML ? Also Moose 4.6 has XML-Parser. Which of XML-Parser or PetitXML would be the better approach ? I've watched http://www.tudorgirba.com/blog/simple-xml-browser-with-glamour but not sure whether than will help me actually load the data into a model. You opinion of these various approaches would be appreciated, and of course pointers to any examples/documentation.

[Pharo-project] Debugger in 1.3
by Schwab,Wilhelm K Feb. 8, 2012

Feb. 8, 2012

Hello all, Somewhere in my misadventures trying to build an image, I lose the ability to open a debugger. Expressions like 'hello' at:200 open one in a clean image, and after loading Migrate and setting preferences (fonts, etc.). It is starting to look like saving after metacello has been doing its thing is the problem - but that's preliminary. Any ideas? Bill

Re: [Pharo-project] Nautilus 4.0
by Fernando Olivero Feb. 7, 2012

Feb. 7, 2012

great! looking forward to use it. Could you provide again the loading gofer script. How does Nautilus deal with Traits, i remember we discussed in the last ESUG, that currently the browser fails to distinguish between methods belonging to the class, and acquired via the use of a trait, which results in an error prone interface.
