AspectS, PHANtom - Aspects in Pharo

by phil＠highoctane.be

Hello, I was wondering what the state of Aspect programming was in Pharo. Googling a bit turned the title mentioned projects. Do we anything loadable and more or less stable for Pharo2.x? I'd like to use some of that. TIA Phil

Indeed but the right level is important ;) I help maintaining Moose and its several couple of tenth of packages as well as the pharoExtras packages so I think that I'm exposed to API changes. Just today I fixed the PharoSound package (full of ugly code BTW) > Currently the package maintainers are the most affected, who would like to provide the same codebase for various versions of Pharo, and/or other Smalltalk dialects. there is a bit of utopia there but why not.

I can control when I want to migrate my apps. > As time passes, and the number of users increases, you'll have to give in, and provide it some way. What I was thinking for example (and I will build it) is an automatic stub creation to support the loading of package where a class is missing in the existing system. I also love the evolution analysis made by andre that generates rules to check migration we should add automatic code transformation. I would like to keep refactoring that we can apply when people want to migrate. And we will get there because we start to have a good infrastructure. So once the infrastructure does not suck all our time then we will build the next generation tools.

You will complain about the fogbuz stuff and we will answer that we hate that google forced us to move. And this is like that. > I see that you're making big changes, but I still haven't seen the breakthrough: I don't see the advantage of using Pharo over another open source Smalltalk dialect, from business point of view. It is just a question of view. For me a new compiler, debugger, inspector, filesystem, http server and many more is enough. And in addition the consortium means that slowly we will give an autonomous live to Pharo not based on free time of people. Stef

About BitBlt current -> BitBlt (Fuel)

by StÃ©phane Ducasse

Hi I just pushed a change cleaning some strange usage. BitBlt was sometimes invoked via BitBlt current (which just returned the BitBlt class). Apparently in Squeak they removed it too. Now it touches Fuel so Fuel guys can you merge on your side too? https://pharo.fogbugz.com/f/cases/12009/BitBlt-current-BitBlt Stef

xD yes, DeepCopier, our old friend! mmmm but it's not about replacing by Fuel or something like that. It was just a random pick for "fix a triviality a day", what Marcus proposed some weeks ago.
