Re: [Pharo-users] [Teaser] Using Pharo to script Unreal

by Dimitris Chloupis

I would not have been able to use Pharo with Unreal if this had failed to work. Also this opens the door for me to use Pharo anywhere I want even outside Unreal, with Python , .Net , Java , assembly and any other programming language. It's a very flexible and powerful solution. The alternatives would have been very hard to achieve or much slower in terms of performance which matters a lot for me.

Re: [Pharo-users] Pharo catalog

by Jeff Gray

Thanks. Is there somewhere I can see the projects and their versions or is that just by investigating via google? E.g. I just found some posts re version of Seaside and followed the advice, so that's now loading. If I want to get others, like bootstrap for example, then I just google it to find out project name and version number of does metacello have a list/browse? -- View this message in context: http://forum.world.st/Pharo-catalog-tp4922782p4922814.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
