Hi, is it possible to hijack Configuration Browser and put there references to my own _local_ projects? Thanks, Peter

Pharo-Launcher Windows 8.1
by Sebastian Heidbrink March 22, 2015

March 22, 2015

Hi, I recently mentioned issues with the installation of the pharo-launcher on Windows 8.1 Turned out I just needed to download the PharoV30.sources file and place into the installation folder. Now everything seems fine. Is this also a topic for the pharo bug list, or is there another place where I can mention this? Sebastian

The Grapher charting engine
by stepharo March 21, 2015

March 21, 2015

Alex Roassal is really cool now I have one question why we cannot say serie1pointsAndVariations :- given series2pointsAndVariations := given RGrapher new axisX; axisY; seriesWithDeviation: {serie1pointsAndVariations . serie2pointsAndVariations}; maxXAxis: 100; My point is why the line connection is not hidden from the user. I think that roassal is a cool scripting engine but it got ***trapped*** there. A primary user wants to have abstractions Then in a second time he wants to open the trunk and script its own. also why don't you have nice default dec := RTDevVarDecorator new. dec moveBehind; desviation: 0.5; color: (c alpha: 0.3); points: pts. => dec := RTDevVarDecorator new. desviation: 0.5; color: c; points: pts. why the decorator should be added to the builder? So see what I mean why do you expose to the user all the design challenges? I strongly suggest that during 1 month you stop to think in term of script. Imagine that you do not have a workspace anymore.

We would like to stabilize Grapher and make it sure it happily fits everybody needs. You can help on it: - When you are tempted to look at the dark side of the planet (this is where R, JFreeChart, gnuplot, D3 and all their friends live), let us know. We will make sure to make you are happy again. - Share your wishlist with us. We already have a long todo list, but your opinion does matter and will take it seriously - we are open to contributions, which could be financial, bug fixe, enhancement, or simply encouragement. I am very happy to be surrounded by very smart engineers. Your encouragement are making them happy :-) Cheers, Alexandre, in the name of the Object Profile Team NB: sorry for the cross-list posting, but this email is very important for us, and for you we hope. -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. _______________________________________________ vwnc mailing list vwnc(a)cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/vwnc

Logic in Pharo ?
by Alain Busser March 21, 2015

March 21, 2015

Hello, I am currently working on mechanical means to solve Aristotle's syllogisms. My project is here: https://github.com/AlainBusser/LogicGame (programmed in CoffeeScript for a webApp). When I will present it (in a little more than two months) I plan to solve the same syllogisms with a software tool which must be free, of course. I am thinking about a lightweighted Prolog. Does this exist on Pharo? Or anything which would be similar (computing in a boolean algebra, something like alt-ergo etc)... and, if it runs on Raspbian it will be even better ;-) Alain

Search and replace source code
by Laura Risani March 21, 2015

March 21, 2015

Hi all, How do you replace all 'expression1' in source code by 'expression2'? I can find them with Finder but don't see any easy way to replace them. My problem is i want to change parameter names in many methods. Best, Laura

Fwd: Re: [ANN] BioSmalltalk

-------- Mensaje reenviado -------- Asunto: Re: [Pharo-users] [ANN] BioSmalltalk Fecha: Wed, 18 Mar 2015 20:53:05 -0500 De: Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> Para: pharo-users(a)lists.gforge.inria.fr Hi, I just found this old mail. I know that BioSmalltalk is well and advancing and I have a friend who works on biocomputing. I Saw the Google Code page of the project, but as a not-programmer I found difficult to understand what is the "selling point" of Biosmalltalk for a biologist... Anyway I'm just curious about which new experience brings Smalltalk to old fields. In my own case, making my notebook for data narratives and visualization has been very enriching and even if there are external tools in other ecosystems to work on it (pandas, Jupyter, LaTeX), the integration with them inside a moldable and modifiable tool is hard to beat.
