What you need is a way to access a zip file containing the resulting image and changes files (either via a ReST API or just plein html urls). To use plain HTML urlrs, take a look at PhLFixedURLsTemplateGroup and PhLHTTPListingTemplateGroup classes. If you come with something generic enough, we could add it to the Pharo Launcher so that others can also use it (if you want).

Reading data from a USB HID device

by Alistair Grant

Hi Everyone, I've got a USB connected heart rate monitor that I'd like to access from Pharo. I found libusb-pharo at https://github.com/tamerescrl/libusb-pharo which appears to do exactly what I want. It was updated only 5 months ago, but doesn't load in Pharo 6.1 or 7, failing with package UFFI-dev not found. Does anyone have a better idea, or know if there is a working version available? Otherwise I'll have a go at getting it working in Pharo 7. Thanks! Alistair

I'll keep you posted! If you want to do so, you can instantiate a PhLJenkins2Server class: PhLJenkins2Server name: âSean''s Jenkins' url: 'https://jenkins.mine' asZnUrl Than add it to the groups class method of PhLTemplateGroupRepository. It should be enough. This mechanism is not good because everything is hardcoded. The list of displayed sources of templates should be defined in a configuration file instead so that it is easily customizable.

Re: [Pharo-users] Question about GLORP class models

by Esteban A. Maringolo

This is a question best suited to the Glorp mailing list (which I'm cc'ing in this email). What you need is an HorizontalTypeResolver, and define a common class as the ancestor for both of your classes. You'll have to define a descriptor for it, and you will use it to reference the "parent" of these (e.g. AbstractQuestion). So in your Glorp Descriptor you'll end up with something like: QuestionDescriptorSystem>>#typeResolverForAbstractQuestion ^(HorizontalTypeResolver forRootClass: AbstractQuestion) QuestionDescriptorSystem>>#descriptorForAbstractQuestion: aDescriptor "..." (self typeResolverFor: AbstractQuestion) register: aDescriptor abstract: true. QuestionDescriptorSystem>>#descriptorForQuestion: aDescriptor "..." (self typeResolverFor: AbstractQuestion) register: aDescriptor. QuestionDescriptorSystem>>#descriptorForQuestionGroup: aDescriptor "..." (self typeResolverFor: AbstractQuestion) register: aDescriptor. Then classModelForSection: aClassModel aClassModel newAttributeNamed: #questions collectionOf: AbstractQuestion I don't know about your model, but if both classes work polymorphically and have a common semantic root (it is "Question"), it is hard for me to see why they don't have a common ancestor. Disclaimer: the above code was written without testing it, based on my memory only :) Regards, Esteban A.
