[Pharo-project] Traits...
by Alexandre Bergel Aug. 31, 2008

Aug. 31, 2008

Hi! Marcus, Stef and I were wondering whether there is fix for copying compile methods instead of sharing when using traits. The idea is to prevent a shared compiled method to answer wrongly when asking for its properties, class belonging ...

[Pharo-project] Cadence enhancement
by StÃ©phane Ducasse Aug. 31, 2008

Aug. 31, 2008

Hi all I got the cadence enhancements: - win32OSProcess - MonticelloSVN - base system enhancement. The last one seems important. Now I do not know how we could share it to go over it. Because this is a bit large. Also the license of this code is SqueakL. So may be we should ask if the code could be license under MIT? Stef

Re: [Pharo-project] Search archives??

Alexandre, Understood, but my real goal was to search the Seaside archives where the analogous downloadable files are a bit less friendly (though appreciated and valuable). Gmane appears to do the job nicely; now I have to read what it found =:0 I added a page to the Wiki, so please add anything you find useful. Bill Wilhelm K.
