[Pharo-project] about the transcript: Model vs Morph
by Fernando Olivero April 27, 2011

April 27, 2011

Hi, I wanted to better understand the issues raised agains the (new) Transcript. Many people are arguing against the current Morph widget displaying the Transcript, complaining that it is read only. The fix is simple, provide a new implementation of TranscriptMorph , which provides cut & paste, scrolling , and the other functionality previously there. This is the announcement on the benefits of the new transcript made by Juan. New Transcript Fast (Calls return quickly) Fast (Updates are immediate) Thread safe Can log to file in addition to Display Display output is optional (for headless images) Can work on a bare bones image (Doesn't need UI, dependency, events, processes) Optional morphic window for seamless integration in Morphic UI framework agnostic. Can be used to debug Morphic, even with the morphic window open, without crashing the image! No longer a text editor. Display is read only. So according to the mails in the list, Pharo disagrees on the last issue, but this means only improving the TranscriptMorph. I dont have time to work on it, but will next week. Are people actually complaining against the (new) Transcript model? or just the TranscriptMorph missing features ? I recall Igor, wanting the Transcript to be polymorphic with the protocol of a WriteStream. Which is already there. Thanks, Fernando

[Pharo-project] squeaksource is down - a different perspective
by Tudor Girba April 27, 2011

April 27, 2011

Hi, squeaksource.com is down a lot. People get frustrated at times. The situation clearly needs rectification. But, here is the thing: I love it! It simply means that the future that seemed to work just fine only a couple of years ago was long overpassed. This is phenomenal growth. And I can afford to love it because the promise of SmalltalkHub is right around the corner. That is so great. I am looking forward to move to it, and then I will be looking forward to getting it on its knees in a couple of years :). Cheers, Doru -- www.tudorgirba.com "To lead is not to demand things, it is to make them happen."

Re: [Pharo-project] Pharo 1.2.1 to Pharo 1.2.2
by Marcus Denker April 27, 2011

April 27, 2011

Hello, In 1.2 we did a bad change: updating is not possible as soon as there is no letter in the version name. This means that you need to change the version number before you can updated. I fixe that in 1.2.2, though, so this is the last time this is needed.
