[Pharo-project] About danny help :)

by StÃ©phane Ducasse

Hi danny I would like to integrate your help system in pharo so we will have see how we can proceed. I would like to add it in a modular way. Does anybody has a nice idea? Now I would really like to see how we can produce some help automatically like by tagging and commenting some cool SUnit tests. At least we should have it in pharo-dev. Stef

Other than that, very nice chapter! Especially liked 1.9 - 1.13, with the thorough explanation of the different ways an exception can be returned from. Cheers, Henry PS.

Re: [Pharo-project] running pharo on iPad

by David Li

Well, I have tried the Pharo-iPhone tree under 3.2 simulator. It works. I am working on making it work with iPad's native resolution. Due to the NDA of that dev kit, I can't really talk much here. Anyone interested in this, please contact me in private message. I do need help in figuring out the canvas drawing codes in the Pharo-iPhone. My goal is to get Scartch to run on this. ;) David
