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

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.

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

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.
