Re: [Pharo-users] SocketStream persistence

by Daniel Klein

I just discoverd the 'noTimeout' message in the 'configuration' protocol, so that solves my persistence problem. But the question remains: When this process is running, it blocks until it completes. How can I fire it up so that I can continue to interact with Pharo while it is running?

As I recall, I just downloaded the one-click .zip file, unzipped it, changed into whatever directory it was, then ran the pharo.sh script. I think I might have needed to `chmod u+x pharo.sh`, but I've been playing with a lot of different smalltalk versions lately, so that easily could have been one of the other dialects.

How are you running it? Maybe you're editing it... Can you do right-clic + run instead of double click?

Hi! The simplest way is downloading the All in One image, and run the .sh in there.
