Re: [Pharo-users] Deleting an instance

by Mariano Martinez Peck

Hi. No, in most object oriented languages there is no other way to remove an object that remove all the references to it and then force a garbage collector. As Laurent suggested, in this case, the better option is to explore the pointers to such objects to see who are ponting to it. cheers mariano On Mon, Feb 28, 2011 at 9:08 PM, laurent laffont <laurent.laffont(a)gmail.com>wrote: > If instance is not referenced anymore, you can: > > Smalltalk garbageCollect. > > If still here, you can search (but not easy) for references with: > > PointerExplorer new openExplorerFor: myInstance. > > > Laurent. > > > On Mon, Feb 28, 2011 at 8:54 PM, DougEdmunds <dougedmunds(a)gmail.com>wrote: > >> 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'.

On the hudson management there is plugin section there one should be able to load plugins by uploading files. Other approach is to copy the plugin to the hudson plugin directory.

For example, the shell script solution of Lukas looks for Debug.log and then suspends the process if one appears. No. But I can easily implement the file checking. The "problem" is that Philippe Marschall has apparently done similar plugin. I don't know if it wise for this small community to develop two similar plugins... I have to check what are Phillippe's plans. My idea was to develop plugin that asks information about ConfigurationOfXXX and desired version and could do building, testing and reporting based on that information. -- Panu

If instance is not referenced anymore, you can: Smalltalk garbageCollect. If still here, you can search (but not easy) for references with: PointerExplorer new openExplorerFor: myInstance. Laurent.

Deleting an instance

by DougEdmunds

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.

Indeed, it uses Moose but just for computing some things, and basically provides a Glamour browser for concerns: unit tests, lint rules, metrics and basic visualizations...

Simple plugin for Jenkins to run Pharo/Squeak VM images

by Panu Suominen

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] rounding errors

by David T. Lewis

Good catch! It looks to me like the root cause is that the argument 2.3 is being treated as a floating point value, whereas in this context it is really intended as a format specifier (i.e. a string, such as you might use in a sprintf() function). I wrote a test to document this bug, and added the fix to Squeak trunk. The test and the modified #printPaddedWith:to: method are in the attached change set.

rounding errors

by t olschewski

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.

Monticello: how to update package-cache listing?

by DougEdmunds

I deleted a mcz file manually from the package-cache directory (outside of Pharo), but when I go into the package-cache repository, through Monticello, the deleted file still appears on the list for that package. What code do I run to refresh the listing of the contents of the package-cache repository for Monticello? -- View this message in context: http://forum.world.st/Monticello-how-to-update-package-cache-listing-tp3325… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Provided packages from Metacello project configuration

by Panu Suominen

This is probably wrong mailing list for this question... Is there a way to define what categories/packages/classes are provided by the given configuration? For example ConfigurationOfXXX project latestVersion providedPackages This would not include the packages that are required by the project and are actually provided by other configurations/projects. If there is a way to produce this kind of package list it would help implementing CI-testing. Testing script would not have to explicitly list what packages to test but could refer to the project definition. Currently one has to alter the testing script every time the packages are changed. With this kind of information one could implement project CI-builds with something like this: whatToBuild := ConfigurationOfXXX project lastVersion. whatToBuild load. HDTestReport runPackages: whatToBuild providedPackages. HDLintReport runPackages: whatToBuild providedPackages. And then it would be easy to build custom Job plugin to Jenkins that would simply ask about the name and the location of ConfigurationOfXXX. -- Panu

Re: [Pharo-users] Package browser?

The latest PDF download is dated 2009-10-28. I would be very happy to purchase a book that was updated. Either through and autobuild or one of the writers could once a month publish a manual build. I spent in total a day trying top get a Laytex environ working on my Mac. I couldn't get the book to build and it left me tons of stuff installed without a clear way to remove. I do understand you are trying to balance having the book open and still make some cash. Maybe you should jside more with making some cash. The barrier to building the boook on your own is high. Just go ahead and strike a deal with one of the book vendors that will manage this for you. Pragmatic Programmers has a great beta books system.

Like Miguel said you should use the image from the website. As you could see on the website a second edition of the book is in the make. I would advize you to start with the current book.

IMHO the only fix is to use the image from the website. There is a reason for this image. If you are a newbie than everything that does not work like it is written in the book is distracting. Giving advize to load a browser that is neither in the book nor is it used by a lot of people is definitely not a good idea. Norbert

What to do after vm crash?

by DougEdmunds

XP SP3 box, Pharo.exe v 4.0.2.0 Image: PharoCore-1.2 I've been using this image for several days. This time when I opened it, it immediately crashed. I've tried starting it several times, including after a reboot, with the same results. I get a popup entitled "Fatal VM error', with some numeric details. When I click ok, it writes a crash.dmp file and closes. 1) Is there a way to to recover the image, if I start with a clean image? 2) Is there anyone who wants a copy of the crash.dmp report? It's about 100 lines long, and I could post it or email a copy to someone.

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Re: [Pharo-users] StandardWindow and SystemWindow

by laurent laffont

StandardWindow is part of Polymorph (so you have all Polymorph helpers defined in TEasilyThemed). You may want to use SystemWindow if you want to distribute a smaller image (Polymorph unloaded) or don't use/like Polymorph. BTW the tutorial is inconsistent, I will change it to use StandardWindow everywhere. Laurent.

StandardWindow and SystemWindow

by DougEdmunds

I'm looking at the tutorial on GUIs at: http://book.pharo-project.org/book/GUI/PolymorphTutorial/Layout/?_s=J-fOIjG… The examples sometimes use StandardWindow and other times SystemWindow. When and why should I use SystemWindow? -- View this message in context: http://forum.world.st/StandardWindow-and-SystemWindow-tp3318409p3318409.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
