[Article] Reddit.st - In 10 Cool Pharo Classes

by Sven Van Caekenberghe

Hi, I published another introduction/tutorial article Reddit.st - In 10 Cool Pharo Classes Implementing a Reddit style web application in Pharo using Seaside, Glorp and PostgreSQL https://medium.com/@svenvc/reddit-st-in-10-cool-pharo-classes-1b5327ca0740 The focus is not so much on the smaller size or the higher developer productivity in Pharo, but more on the fact that we can cover so much ground using such powerful frameworks, as well as the natural development flow from model over tests and persistence to web GUI. This is a more intermediate level article that assumes basic knowledge about Pharo (language and IDE). https://ci.inria.fr/pharo-contribution/job/Reddit/ http://www.smalltalkhub.com/#!/~SvenVanCaekenberghe/Reddit Enjoy! Sven PS: This article is actually an update of an article that I wrote in 2010 and that became unavailable/outdated. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

Re: [Pharo-dev] Spec license

Thx.. Here I repost, an alternative framework to wire up Morphic UI: * Implicit spec, full layout described spec and table layout based spec options: http://skrishnamachari.wordpress.com/2014/09/01/reviving-pharo-morphic-view/ Model / View / Controller hooks exists, the additional parts of the 2012 works, needs to be refactored for Pharo 3.0 and will be posted later. Specially the ValueHolder capability for all morph widgets. The framework works on 3 base and minimal support classes on top of the existing morphic framework.
