So can you try the pharo image on the squeak vm because this is probably a problem with a plugin. Stef

vincent which vm are you using? On which OS are you? Because on mac lion I used the cocoa blessed VM and it works that is on jenkins. Now on 64 bits I do not know.

Re: [Pharo-users] Package browser

by S Krish

The PBE is not in Sync with 1.2 onwards in details like there.. Pick the stable 1.3 release : OBSystemBrowserAdaptor is correct one for the OBBrowser to show up. Easy to recognize with lots of Refactor menu when you right click on Classes... and also a text box on the top of the browser Browser: Gives you a plain vanilla browser Both of them should show Pacakges.

I use it mainly for teaching at the university: - Free (no cost) and Free (open source) - The easy setup allows my beginner students to focus on OOP topics - Several integrated tools: programming environment + test framework + coverage tool + source control tool. All other popular langages (java, ruby, python, etc, etc) requires several downloads (and setups) to do the same - It is portable between different OS and the features we use work exactly the same way everywhere Saludos!

Package browser

by Vincent Lesbros

I did not find how to get the OB Package Browser. My Browser displays categories, but not packages. in the top right menu of the Browser, item "Choose new default browser" I have only two choices : Browser OBSystemBrowserAdaptor In the book PBE1-2009-10-28.pdf "Pharo by Example " it is showned a OB Package Browser ... But how can I get it ? (I did read FAQ 5, p. 318.).

Memory

by Vincent Lesbros

Hi What is the maximum size supported for Arrays in Pharo ? I have to manipulate a lot of Pixmaps and large sound files. for example : 30 minutes of 4 channel sounds in 32bit at 48000 Hz = 30 * 60 * 48000 * 4 * 4 = 1 382 400 000 bytes. 1 picture 3648 * 2736 pixels 24bits/pixel = 29 942 784 bytes. How many pictures can I load in memory ? My physical memory is 8 GB. VL.

Sounds / Silence

by Vincent Lesbros

Hi, I am new to Pharo, I try to get a sound from the SoundPlayer. I use : Pharo-1.3-13315-OneClick.app I did : BaseSoundSystem soundEnabled: true I create an instance of AbstractSound, from the beep example, or an instance ofPluckedSound... whatever. And, when I send the message play, the primitive to play the sound fails. *primSoundStartBufferSize: bufferSize rate: samplesPerSecond stereo: stereoFlag* "Start double-buffered sound output with the given buffer size and sampling rate. This version has been superceded by primitive 171 (primSoundStartBufferSize:rate:stereo:semaIndex:)." "ar 12/5/1998 Turn off the sound if not supported" <primitive: 'primitiveSoundStart' module: 'SoundPlugin'> *SoundSupported := false.* La primitive Ã©choue et le flag *SoundSupported est remis Ã false.* * * *My environnemt is windows 7 64bits,* *I do have a sound card !! * * * * * *Where is the good plugin and how should I activate it ?* * * *thanks,* * * *VL.* * * * *

The core is simple. Easy prototyping. It's a place to learn. Nice community. So this is my platform of choice to try things, prototype, create my tools. The Plastic metaphor seems correct. But keep in mind we have to choose programming systems because they solve problems. - what kind(s) of problems Pharo will solve best ? - what kind(s) of users Pharo want to have ? It looks like Pharo has a real place on tablets (Hilaire proves it with DrGeo). Now I'm not sure about "essence of agile". TDD in Pharo does not seem so popular - there's more and more tests, but feedback on testing practices is low. I would like to see timeboxed iterations with goals for Pharo development process - that would be agile and provide a rhythm.
