Re: [Pharo-project] System browser in Pharo 1.4

by Benjamin

In the previous version of Pharo, I think you used OBBrowser. But the default browser has always been Browser (the one in 1.4 with a flat display of classes). Indeed it's hard to read, that's why I can propose you to have a look at Nautilus (the new default Browser which is working on 1.4) Gofer new squeaksource3: 'Nautilus'; package: 'ConfigurationOfNautilus'; load. ConfigurationOfNautilus loadRelease Have fun :) Ben On Apr 26, 2012, at 3:43 PM, Olivier Auverlot wrote: > Hi, > > This is probably a stupid question.

[Pharo-project] System browser in Pharo 1.4

by Olivier Auverlot

Hi, This is probably a stupid question. Why in Pharo 1.4, the system browser does not display classes hierarchically in the column instances / class. Each class is displayed at the same level. It's not easy to read. How to get the same behavior as in previous versions of Pharo ? Best regards Olivier

Re: [Pharo-project] Confused about #isDirectory

by Camillo Bruni

we changed that not so long ago :) but it will do the same.... the problem will be that the VM primitive might not follow symlinks (that would explain the first line) no clue though why it should return false for '/private/var'...
