Support for git in Pharo
by Stephan Eggermont March 6, 2014

March 6, 2014

How is git support for Pharo going to work? Because currently it takes extra effort. I noticed some Pharo users moving their code to github, making it less accessible. I know a few different ways to get git installed on a mac: (finkproject, brew, macports, xcode, git-osx-installer, git-scm.com) and they result in git not always being /usr/bin/git. Then there are the differences between system wide installs and installs for specific users, and the different OS versions. Stephan

But can that account for a delay not being executed (or prematurely terminated)? In the example I posted, the 10 second delay takes no time at all (second precision unfortunately because of the division by 1000). Max > > Dave

About inspectors
by Pharo4Stef March 6, 2014

March 6, 2014

hi guys how could we make clear that class (the second item when inspector an object) is not part of the object itself. I found that confusing to get mixed self/class/allinstvars and the instVar. When navigating nested structures this is annoying to ask ourselves what do we see exactly. Stef

Where are the Pharo sources?
by Oscar Nierstrasz ＠ gmail March 6, 2014

March 6, 2014

Just downloaded the latest Pharo image from the project page. I can find the VM, image and changes files, but no sources. I tried various older downloads too, but I can't find them anywhere? Can anyone fix it? Oscar

https://developers.google.com/glass/tools-downloads/client-libraries Is anyone working trying out Pharo API to Google glass? Pharo-Android per se being the base in this.
