[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!

Re: [Pharo-users] Generate latex from Pharo

http://smalltalkhub.com/#!/~Pier/Pillar "LaTeX embedding: LaTeX is very useful to write mathematical formulas for example. It would be nice to be able to embed LaTeX formulas inside a Pillar document and get these formulas fully exported. Org mode does something similar already."

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