Re: [Pharo-users] [vwnc] The Grapher charting engine

Hi! > If you're heading to make "Roassal the best visualizing engine of the Universe" then what are your intentions with connecting it to the outer world ? This is a rather broad question :-) While our visualizations are meant to run in a standard Smalltalk environment, they are exportable to HTML. Interaction are also preserved. Here are two simple examples: https://dl.dropboxusercontent.com/u/31543901/TMP/memoryBlueprintExample.html <https://dl.dropboxusercontent.com/u/31543901/TMP/memoryBlueprintExample.html> https://dl.dropboxusercontent.com/u/31543901/online/WebReport/seisms.html <https://dl.dropboxusercontent.com/u/31543901/online/WebReport/seisms.html> And a larger and more complex example is in the file https://dl.dropboxusercontent.com/u/31543901/TMP/ExampleReport.zip <https://dl.dropboxusercontent.com/u/31543901/TMP/ExampleReport.zip> check the file Example.pillar.html > Will it remain a multiplatform toolbox ? Or are you heading towards a BI desktop or Web app ? Roassal will remain closely linked to Smalltalk (VisualWorks & Pharo).

Re: [Pharo-users] [Moose-dev] Re: [Pharo-dev] The Grapher charting engine

Yes. Although RTDevVarDecorator is not rooted into strong maths. It was more an experiment. If you look at the class RTDevVarDecorator, you will see it is quite simple. Adding decoration in a chart made with Grapher is very simple.

Cleaning/Simplifying Nautilus
by stepharo March 22, 2015

March 22, 2015

Hi I want to clean Nautilus and to simplify its code and functionality. In addition I want to reduce to student load in the context of the Mooc we will start to work on. So I want to remove the lock mechanism and the multiple methods. This was an experience that did not really work. It was nice to try but it is time to remove that. So I hope that not many people use this feature. https://pharo.fogbugz.com/default.asp?15199 After I will start to clean the group to keep a consistent and useful subset. Stef

Why this: [ 1/0 ] on: ZeroDivide do: [:ex | ex resume: 1 ]. returns 1, but this: [ 1.0/0 ] on: ZeroDivide do: [:ex | ex resume: 1 ]. hangs (causes infinite loop) ? -- View this message in context: http://forum.world.st/Confusing-ZeroDivide-tp4813627.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

about Groups in Nautilus
by stepharo March 22, 2015

March 22, 2015

Hi I'm analysing the behavior of groups in nautilus. - Add group works well. This is really cool to be able to promote a package in the top focus list. The problem is that the group is not polymorph to a package so we cannot publish.... but for now this should be ok. -2 Now Add as Groups & Browse does not work for me since it open a browser that only contains the groups but the refresh ... does not work. Then this is strange because after we can still find a class that is not in the original package. - 3 Now Add Matching ... could work if ask for a pattern and stop to browse (cf above). - 4 Add in group does not propose the currently available groups (only Work) - merge groups -> raises a DNU So I will remove 2 and implement 3 https://pharo.fogbugz.com/default.asp?15202 Stef
