Re: [Pharo-users] Dr Geo: A point needs to be animated over a preexisting object?

You refer to something else but scripting. Ideas are cheap, implementations are expensive, so if there are no more coder behind Dr. Geo but me, cheap ideas will not get there quickly. So in between I will stick to the hacking open mustang model (i.e. Dr. Geo Smalltalk sketch and Dr. Geo scripting) Hilaire Le 25/09/2015 14:21, Offray Vladimir Luna CÃ¡rdenas a Ã©crit : > Thanks Hilare, > > My students have choosen Geogebra for their work.

The main difference is philosophical: Dr. Geo is an open box, Geogebra a close box. Dr. Geo is a mustang car you may want to mix in. Geogebra is a bmw car you don't want to mix in. Of course the analogy is over simplified. Hilaire -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

Hi Jimmie, Iâm happy to be of help. Yes, Spec is also the standard UI builder in Pharo 5 and probably will stay that way for a long time. > On Sep 25, 2015, at 00:53, Jimmie Houchin <jlhouchin(a)gmail.com> wrote: > > Hello Johan, > > Thanks for the information.

My wife is a maths teacher and they do Geogebra too. Tried to get her on DrGeo, still not won but we'll get there. What is a key differentiator of DrGeo ?

Thanks Hilare, My students have choosen Geogebra for their work. Mainly because of the many videos and the ability to mix scripting with graphical interface like shown in [1] and the use of spread sheet view in the interface [2], which is closer to what they want to do with their students. [1] https://www.youtube.com/watch?v=Wwtv2aZwf4s [2] https://www.youtube.com/watch?v=VtYdHTNwjmU May be these videos and interface could help in cross-pollination of ideas for Dr Geo.

Is this possible? Yes, in that case you use Dr. Geo script. But again, Dr. Geo Smalltalk sketch fit better your situation, as you described it. If you have 100 samples, you will have to use 100 times the same script in a the mouse environment, tedious. Hilaire -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

Breakpoint ?

by Nic

Hi all, on the ESUG 2014 was a demonstration of Breakpoints in Pharo. Did somebody know what project I can load to get them or how far they are with it? Regards, Nic

Re: [Pharo-users] Problem Loading Roassal 2 development in Pharo 4

by Offray Vladimir Luna CÃ¡rdenas

Thanks Alexandre, This week we're on our second version of the dataweek[1]. After installing grafoscopio (based on Roassal and GT-Tools) the next activity was to browse the examples, but in the workshop we got an error, so we weren't capable of see anything. In our previous workshop, browsing the examples was one of the first motivational activities to see the power of visualization on Pharo... now this doesn't work... We move on in our workshop to the pharo tutorial and data scrapping, but the browsable gallery was certainly a really good experience to newbies. [1] http://mutabit.com/dataweek/ Grafoscopio is still pretty alpha and I didn't release it because there still a lot to learn and to improve and Pharo 4 was coming. I'm trying to create a new GUI which uses Spec-Glamour and having a stable platform to develop on is important. Nice to have a dynamic environment, but sometimes it seems that you're chasing a moving target.

Re: [Pharo-users] Integrating a custom spotter, reusing current code

by Andrei Chis

Hi Stefan, Now when using a filter you can configure each processor individually. Here is a full example of an implementors browser on a method with dive in support: http://ws.stfx.eu/GK4T298XWAS8 I just added the minimum API to configure individual processors. I added more examples that you can see by inspecting the GTSpotter class and selecting the 'Examples' presentation. For now this only works in the latest moose image.
