rounding errors
by t olschewski March 1, 2011

March 1, 2011

Hi, using formatted number output recently I got the following output: 1.0 printPaddedWith: $0 to: 2.1. "'01.0'" 1.0 printPaddedWith: $0 to: 2.2. "'01.00'" 1.0 printPaddedWith: $0 to: 2.3. "'01.00'" <-- wrong 1.0 printPaddedWith: $0 to: 2.4. "'01.000'" <-- wrong 1.0 printPaddedWith: $0 to: 2.5. "'01.00000'" running Float>>printPaddedWith:to: in the debugger showed me that the reason of this odd behaviour seems to be produced by Float>>truncated and/or Float>>fractionPart. I can provoke errors of that kind even easier: (2.3 fractionPart * 10) truncated. => "2" (instead of 3) In Primitive 51 (primitiveTruncated for Float>>truncated) I read frac = modf(rcvr, &trunc); so the problem looks like an issue with rounding errors in Math-Library's modf function. Indeed, I can reproduce the odd result of "(2.3 fractionPart * 10) truncated." in C++ using modf: // g++ -lm truncate.cpp && ./a.out #include<iostream> #include<cmath> using namespace std; int main(){ double f1, f2, f3; modf(10 * 0.3, &f1); cout << f1 << endl; modf(10 * modf(2.3, &f2), &f3); cout << f3 << endl; } // output: // 3 (ok) // 2 (error - should be 3) Question: what can be done about this? As a matter of fact, several important methods spread over a number of classes (Float, Number, Morph ... being among them) are senders of Float>>truncated or Float>>fractionPart, so rounding errors in primitive 51 or 52 could provoke unexpected behaviour in surprising places. -- View this message in context: http://forum.world.st/rounding-errors-tp3327130p3327130.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

left scrollbars
by t olschewski March 1, 2011

March 1, 2011

Hi, what is the default way of getting left scrollbars - is there a setting? Obviously I can modify ScrollPane>>initialize to set scrollBarOnLeft := true, but maybe there is a better way. When I am pulling a scrollbar, I am always looking at the line starts not ends for judging how far I've got to scroll, so left scrollbars are more usable to me. -- View this message in context: http://forum.world.st/left-scrollbars-tp3329476p3329476.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Deleting an instance
by DougEdmunds Feb. 28, 2011

Feb. 28, 2011

Is there a way to delete/remove/kill an instance other than by quitting and starting Pharo up again? In my example, I installed the ContactListEditor package from http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html After several "ContactListEditor open" doIts, I closed most of the windows. I inspected "ContactListEditor allInstances" and it has an array of instances, one for each 'doIt'. The instances are still 'alive', including those whose windows were closed. If I save and quit Pharo, and restart it, the only instances that are alive are the ones that have open windows. -- View this message in context: http://forum.world.st/Deleting-an-instance-tp3328590p3328590.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Is there a metric server for Pharo
by Panu Suominen Feb. 28, 2011

Feb. 28, 2011

This time I ask before implementing something that has already been done. :) I know there are quite good tools for metrics and code quality control. However I don't know if there is any software to publish these kind of results. In Java world there is Sonar (http://www.sonarsource.org/) So, are there any tools to publish code quality metrics? If not I am going to see if sonar can be used to archive this task... someday. -- Panu

Simple plugin for Jenkins to run Pharo/Squeak VM images
by Panu Suominen Feb. 28, 2011

Feb. 28, 2011

I don't know if there will be any use for this, but I had couple of free hours last weekend and I made simple plugin to run Squeak/Pharo images inside Jenkins CI-server (formerly Hudson). After installation one should be able to configure Squeak/Pharo VM under hudson management. After that one is able add build step that runs Pharo/Squeak image. One can define parameters, image and script that is passed to the given image. I will improve documentation and such when I have time. However I will do it faster if there is some interest towars this kind of plugin. Codes can be loaded form the github. (mvn package should compile plugin under target dir). https://github.com/pnuz3n/Jenkins-Pharo-Plugin There is precompiled version currently available at URL. http://users.jyu.fi/~pajumasu/jenkins-pharo-plugin/jenkins-pharo-plugin.hpi -- Panu

Re: [Pharo-users] SimpleWebDoc question
by laurent laffont Feb. 27, 2011

Feb. 27, 2011

Hi Marco, I've put the working image here: http://lolgzs.free.fr/pharo/simplewebdoc.zip Note it uses Pharo pre-1.0 and Seaside 2.8. The nice url http://localhost:8080/Collections is handled by SWDocView>>initialRequest: I don't know if it works with Seaside 3. I haven't looked back at SimpleWebDoc for more than one year, and I've written it to learn so it's hacky. No problem to post future questions, but I think that posting on pharo-users list is even better (I read it). And thanks to look at this project. Cheers, Laurent.
