broken GitFileTree/IceBerg on Windows because of ProcessWrapper

by Peter Uhnak

Hi, GitFileTree / IceBerg is now broken, because ProcessWrapper (one of the deps on Windows) is downloading plugin from http://leves.web.elte.hu/ProcessWrapper/ProcessWrapperPlugin.dll But of course since the domain is down, it breaks everything. Not the mention downloading dll over http. Peter

IceBerg and push for projects vs packages

by Peter Uhnak

Hi, one thing that I wanted to ask about IceBerg --- during the IceBerg talk Nico mentioned that we need to think in terms of projects. Now I understand that perspective, because that's how git behaves and that's how _I_ think, however at the same time, there is a strong push for focusing on packages... having each package describing it's dependencies, etc. So my question is, how do those two views interact with each other? Because I feel like they are going against each other. Peter

Re: [Pharo-dev] About asClass and friend

by Ben Coman

Here is an example where asClass is useful. Someone posts something in the mail list like this... Gofer it smalltalkhubUser: 'hernan' project: 'CodeGenerator'; configuration; loadDevelopment. CGSmalltalkExamples exampleNSISPharo4. and pure laziness (apparently a sign of a good programmer??[1]), I'd like to be able to select from the web page, paste and evaluate the whole thing in one go, but CGSmalltalkExamples is unknown and cannot compile. But for my personal use, that is my only example. I wonder if the following proposal may be a reasonable alternative approach to put on a project's documentation page... Gofer it smalltalkhubUser: 'hernan' project: 'CodeGenerator'; configuration; loadDevelopment; eval:'CGSmalltalkExamples exampleNSISPharo4'.
