Thank you! The problem is of course less one's own packages, but the big packages we depend on, Seaside, Glorp, XMLSupport, â¦ Sven

Re: [Pharo-project] Morphic replacement

by Fernando Olivero

Thanks Sean, for now not much, once i release it would be nice if people try out the examples, run the tests, and hopefully prefer it over current UI frameworks and start building apps (widgets) on top of it, and helping me improve it. I'm kinda stuck with finding a name for it, because Gaucho is the name of IDE that will be built on top of it. Fernando On Mon, Nov 28, 2011 at 4:35 PM, Sean P.

Re: [Pharo-project] Athens work in progress: couple screenshots

by Igor Stasenko

Thanks, Fernando. There's one more thing: it takes like 20 seconds to load a library. When i first time run the example, i thought that it is going to crash, because of colorful wheel appeared instead of mouse pointer (usually a sign that VM going to crash ;). But it worked from first start. I don't know however why it takes so much time to initialize the library, when you first time loading it with VM.
