Cleaning up Voyage Documentation

by Johan Fabry

Hi all, I am building a small app that uses Voyage and MongoDB as the database, and so I had many questions regarding how to use it and found the documentation lacking. After conversing with Esteban, I proposed that I improve the 'Pharo for the enterprise' chapter on Voyage, based on his responses to my questions. (See https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… and https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english/tr… for the sources) So a heads-up: I would like to take a 'lock' on that text for some days (to avoid conflicts and the associated unpleasantness), as I go improving and expanding it in the next few days. Also, if you have questions and/or remarks about Voyage and/or the documentation, shoot! I will do my best to address them.

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .

by Hilaire Fernandes

Hello, You may want to calculate the distance between the mouse position and your path (I guess a bezier curve). Then given this distance and a tolerance to zero you decide if the mouse position is more or less on your path. Calculating the distance you will also get for free the place where to add a point on your path. http://blog.gludion.com/2009/08/distance-to-quadratic-bezier-curve.html Hilaire Le 14/11/2013 21:07, kilon alios a Ã©crit : > In order to do that I will have to check that the line passes through a > specific pixel. Or to be more correct that the place that mouse has > clicked is where my path passes through. How I do that ? Can Athens do > that ? Can athens tell me which pixels my path passes through ? > -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] Writing a GUI - Where to start?

I recommend you to go with Spec. It is the newest and designed to be the most capable. It is also the way forward, it will be the 'standard' GUI builders in the future. We know that the documentation right now is far from optimal. Ben and I will work on that in January.

Re: [Pharo-users] How to discover which test fails (pharo 2.0)

by Davide Varvello

Hmm, I think it is more comfortable to select packages and run all the tests. Within the test runner you have to filter for packages than select all tests, than if you add a TestCase you have to mind to select it because the tool does not automatically add the new TestCase in the tests to run. I think that select packages and hit test run is faster and cozy.

Help with SQLite3 package

by Michel

Hi pharoers, I am a newbie with Pharo. I installed the SQLite3 package in the Pharo2 image with the MetacelloConfigurationBrowser and tried a test with this script : db := SQLiteConnection fileNamed: '/home/michel/base_CD/BaseCD.db'. resu := db executeQuery: 'SELECT * FROM T_album'. resu inspect. And I got this error : External module not found. I am on Fedora linux and I think that I should give somewhere (in SQLiteReference class ?) the address of the libsqlite3.so file. Am I right ? Kind Regards, Michel.

Polymorph is not a layer on top of morphic, itâs just a (relatively unstructured) extension. We actually need to take PolyMorph and Morph an restructure the package -> extensions of Polymoprh need to be moved to Morphic -> the widgets of both PolyMorph and Morpic needs to be moved to a Morphic-Widgets package -> everything needs to be cleaned up. There are far too many specialised subclasses and strange duplication (we have still how many button classes?) Marcus

Hi everyone, Nobody mentioned Polymorphic. My understanding is that both Spec and Polymorph are built on top of Morphic. I only looked at code example and brief tutorial for both of them, but it seemed to me that Polymorph was easier to grasp: it's quite obivous in the code where and how the widgets are built. I have trouble understanding how the job is done in Spec. On the other hand, Spec seems to have a lot of users in this mailling list.

How to discover which test fails (pharo 2.0)

by Davide Varvello

Hi! I'm on Pharo 2.0. When I run a bunch of tests I usually select a lot of packages from Nautilus and click cmd-t to run them, but unfortunately if one test fails, only a yellow box in the lower left appears and it's time consuming to look for which test fails in which package. I'd love to have the good old dialogs with all the failing tests. Is there a way, in the configuration, to have them back?

If your sockets are connection oriented (it is. TCP) using IP Multicast won't be an option. Multicast was made with Datagrams in mind instead of Packets. Though there was a multicast solution that numbered the datagrams to request retransmission in case of packet loss. Regards, Esteban A.

Hi all! Im making some performance enhancement on PhaROS, i realised that one of my common scenarios is having several sockets that should receive exactly the same information, in order to do that, im using n calls to the vm, which does n system-calls. I was wondering if there something done in: - send the same data to all the sockets in just one primitive - send the same data to all the sockets in just one syscall.
