I found a bug in Pillar syntax when I type 3 + 4 , it seems like it takes + as part of the pillar syntax and uses latex syntax and when it tries to generate the pdf it fails so I am forced now to type it as raw text like this : {{{3+4}}} also I would like the ability to have a dark background for text like we do with smalltalk syntax . Pharo Tour chapters proceeds well, I compile to both latex html and pdf , I see no problems so far with my text, I copy my text directly from the latex files of the original PBE in github. I also improved the Readme. On Thu, May 8, 2014 at 9:16 AM, stepharo <stepharo(a)free.fr> wrote: > > > I also added Chapter 1 - Quick Tour in Pharo.

well I will keep an eye on it , its certainly interesting . I also love that you expose the full Pharo IDE to the user. I may contribute at some point, I promise nothing but creating a tool that is easy to use for adults with no knowledge of coding is certainly my goal too.

Now, I extended and created phratch for adult. The idea is to prototype easily, without remembering the source code, or learning source code. For example, to use the robot Ev3, it is really easy to obtain something that works without knowing the API. I have a lot of idea to extend phratch, for example: - add an API on top of Roassal - add an API for Arduino All should be done, but I need time or contributors :) Cheers, Jannik > > > On Sat, May 10, 2014 at 10:16 AM, stepharo <stepharo(a)free.fr> wrote: > >> Superb! >> >> Stef >> >> >> On 10/5/14 08:27, jannik laval wrote: >> >> Phratch 3.0 is out of the box, good news ! >> >> Phratch 3.0 is cleaner, faster and more stable. >> Phratch 3.0 is on top of Pharo 3.0 >> >> Thanks to the 30 students of Ecole des Mines de Douai, who use Phratch >> + Jetstorm, we improved a lot the stability and the rapidity of phratch. >> Now, we can say that it is usable. >> >> There is no new feature in phratch3.0.
