Re: [Pharo-users] Pharo-Launcher Windows 8.1

by kilon alios

Bottom line is that reporting a problem in the mailing list first makes much more sense because a) Way more likely to get an answer b) Avoid adding to the list on non existent bugs in fogbugz c) Bring the bug if it really exists to the attention of more people, hence increase that chance of the bug getting a fix. d) Far easier to remind people of the bug later on by just bumping on the thread which everyone on the list will get notified compared to fogbugz that if you are not subscribed to a bug you wont be notified. So yes definitely want to discourage people from starting from fogbugz. Also personally I dont like fogbugz because its so isolated.

Re: [Pharo-users] Logic in Pharo ?

here's another one http://www.smalltalkhub.com/mc/goonsh/Prolog/main works in pharo 2.0. I think they are copies of AOKI Atsushi's version.

As long as you can list the detailed steps reproduce the problem, then its worth putting in fogbugz. However fogbugz has a lot of old issues and sometimes a new issue is like a lost tree in the forrest. Its generally beneficial if you socialise it on the mail list as well. A good workflow is: 1. Search fogbugz for similar issues. 2. Ask on the mail list if its a known issue, or if you should create a new one. List your steps to reproduce and ideally a solution. 3. Log a new issue on fogbugz, copying the mail list discussion there. Paste the link back to the mail list thread. So in general: * the mail list has a broader audience and gets a better triage * fogbugz tracks history to ensure it doesn't get lost - and nothing happens except what goes through the tracker.

The Grapher charting engine

by Alexandre Bergel

Dear all, As many of you know, Grapher is a Ã¼ber-cool charting engine, part of Roassal. For people who do not know what Grapher is, here is a (compelling we hope) example: Which is obtained by the following script: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | b colors points ds pts dec lb | b := RTGrapher new. colors := Array with: Color red with: Color blue. points := OrderedCollection new. colors do: [ :c | ds := RTStackedDataSet new. pts := ((1 to: 100) collect: [ :i | 50 atRandom - 25 ]) cumsum. points add: pts. ds points: pts. dec := RTDevVarDecorator new. dec moveBehind; desviation: 0.5; color: (c alpha: 0.3); points: pts. ds connectUsing: (RTLine new color: (c alpha: 0.5); width: 1 ). b add: ds. b addDecorator: dec. ]. b axisX; axisY. b build. lb := RTLegendBuilder new. lb view: b view. colors doWithIndex: [ :c :i | lb addColor: c text: 'Series ', i printString ]. lb build. b view @ RTZoomableView. b view -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= In our grand vision of making Roassal the best visualizing engine of the Universe (we also know to be modest time to time, but not today :-), Grapher will play a very important role. 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 ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Re: [Pharo-users] A Pillar language package for Atom editor?

by HernÃ¡n Morales Durand

Ok, alternatively, is someone generating Pillar chapters in Windows? My problem is GT-InspectorExtensions-Pillar highlights the syntax but not properly (see attachment). Could I be using a wrong syntax? I also figured out a command line to execute pdflatex passing a modified PFTE.tex, but latex errors are cryptic (and I don't want to follow there).
