[OT] Pharo pi machine

by Torsten Bergmann

Got my Raspberry Pi B+ with a TontecÂ® 3.5 touch screen display to bootstrap into Pharo. The Raspberry Pi from CI (https://ci.inria.fr/pharo/view/RaspberryPi/) worked out of the box on Raspbian. Nice!

To help the person who'll need to use Pillar from Pharo I added some documentation about it on the Pillar's documentation: https://ci.inria.fr/pharo-contribution/view/Books/job/EnterprisePharoBook/l… On 17 May 2015 at 13:03, Jan ValÃ¡Å¡ek <valasja7(a)fit.cvut.cz> wrote: > Dne 2015-04-20 14:12, Damien Cassou napsal: > Hi Damien, > > Finally, I have used both ways in my work.

Re: [Pharo-users] Generate latex from Pharo

Is there anything already done to generate code related to math environment? I would like messages like: Fraction>>asMathLatex that returns $\frac{numerator}{denominator}$.

Re: [Pharo-users] how to see methods implemented in super classes

by stepharo

The problem is that you have to flatten inheritance so this means that we would have to prefix methods based on the classes because just putting grey does not help. Long time ago there was such browser but it was not really good so we removed it. Now put yourself in inheritance mode and you can quickly browse the superclass.
