[Pharo-project] Class not showing in the browser
by Hernan Wilkinson April 22, 2009

April 22, 2009

Hi, I'm having a problem when filing in classes from Squeak, the do not appear in the browser althoug they are in the image. Does somebody know how to fix it? BTW, I fixed a bug when trying to redefine a class. If you press the button "Cancel" (not the option cancel) it does not work. How do I summit the fix? (sorry for asking this to the list, but I do not have too much time to look in the web page to see how to do it...) Hernan.

[Pharo-project] syntax highlighting - how?
by Cameron Sanders April 21, 2009

April 21, 2009

Sorry to ask such a basic question, but how do I enable syntax highlighting in Pharo? I updated to the 4.0-closure vm (on a Mac) two weeks ago. Shout is not in the package list in Monticello, so do I need to add some repository? I have searched the preferences on words like color, syntax, highlight, and variations, and I struck out. And when I have a question like this, what is the best place to look for the answer? Many squeak specific notes (historical postings) do not seem to always apply to Pharo. 4.0 seems to be working great! thanks in advance, Cam S

Hi all I published a ThreadSafeTranscript on Squeaksource (same name). Lukas already fixed some of my terribly obvious mistakes :). I would like that we see if this little guy is getting well and replace the old one. Since for teaching concurrency having a strange transcript is a pain. Stef
