Hi, I noticed that http://www.squeaksource.com/JSON.html has no license specified. Is that on purpose or is it actually open source?

Hi, I am using latest pharo image. I installed scouchdb and other libraries from squeaksource. As isaid before the inspected stream content looks ok. I will try with a fresh image. May be it works.

Re: [Pharo-users] Pharo-users Digest, Vol 4, Issue 9

It is just classes. If you want to develop your "home office" separately from your "study" then you should look to put them in separate packages that you can load separately. However, consider your dependencies carefully. The problem with every object able to touch every other object leads to spaghetti issues. cheers, Mike On Tue, Apr 6, 2010 at 2:07 PM, DeNigris Sean <sean(a)clipperadams.com> wrote: > Thanks for all the replies - this is great! >>> Got it.
