Re: [Pharo-users] GSOC 2015 Call for Ideas

I am not an expert in Pharo in any conceivable way, but I have tried to learn it over the past few weeks. I think that an area where the interactive tools of Pharo would really shine is that of data visualization, inspection and mining. Pharo already has very good tools - such as Roassal2 - for da

Re: [Pharo-users] GSOC 2015 Call for Ideas

Andrea, not sure if I would call Sinatra lightweight. If you want to build a RESTFul API, there is absolutely no need for Seaside at all. You can just use the underlying HTTP server layer, in Pharo that would be Zinc. There also is a REST interface for Zinc, so all you need is there already.

[Pharo-users] What happens to saved inspectors?

Hello I am using Moose 5, which is essentially Pharo 3, downloaded late December 2014. I have a development project which mainly consists of a collection of workspaces and inspectors (I really do intend to turn it into a properly structured set of classes one day!). I have noticed that, wheneve

Hey, Inspectors are different between Moose and Pharo 3. Can you precise, are you using the Glamour inspector, the EyeInspector or the old Morphic inspector ? I have never seen that in Pharo. Are your titles dynamic (I mean, when the object changes, can your title change ?) ? 2015-02-18 11:35 GM
