Re: [Pharo-project] why TextMorph and PluggableTextMorph are not

Lukas I think that we should try it. Because I think that is still dust and bugs there (like the possiblyChanged I encountered yesteday). I will have a look soon.

Re: [Pharo-project] Syntax errors while loading a package

by Schwab,Wilhelm K

This is a fairly big usability hassle, but I have typically been doing even worse things to the code (SIF, followed by search/replace with the regex package), so I typically have gone hunting for the snag (usually an improperly terminated cascade, which Dolphin 5.x happily compiles, hence the large number of them in my code), exit Pharo, re-run, re-load and look for the next error. It's a pleasant surprise when it finally loads cleanly. It would be better to have a clean way to cope with these things.

Thank you Sean, it load now. I only wish the library had some test cases or description since it's not obvious how to use it. On Wed, Aug 18, 2010 at 2:55 PM, Sean P.
