Thanks for helping me out pharo -v pharo: command not found ldd pharo Â Â Â linux-gate.so.1 =>Â (0xf779f000) Â Â Â libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf7755000) Â Â Â libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf7750000) Â Â Â libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf7734000) Â Â Â libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf758a000) Â Â Â /lib/ld-linux.so.2 (0xf77a0000) Yes my project is called "Ephestos" and yes I could still target Blender, though I am also considering focusing more on extending Pharo. If I get it to work that is , because I am certainly motivated but learning all these stuff is very time consuming so far. My goal is to keep adding new graphic , music and IDE tools to pharo. Blender integration is relatively easy since I am quite familiar with python. My ambition so far is to offer an interactive tutorial tool, flexible GUI designer and a painting application (basic funcionality at first)Â in the next 1-2 years to pharo, together of course with the blender / python bridge. I am also interested in creating a pharo front end for super collider for audio synthesis and music composition. Thats tons of stuff, but I am not in any hurry if pharo can accomodate my needs I can invest even decades if that is what it takes.

That was an obvious one, I should have guessed it . I did try it , it report the same permission denied error. I will continue searching for a solution for it. Again thanks for helping me out. Regarding audio or music synthesis coding I am not interested in doing that myself because its a lot of work. Supercollider is a live coding enviroment , its basically a server app that can be controlled through socket messages to be precise, the osc protocol. Its a tool used by professional musicians and is both extremely flexible and very fast. http://supercollider.sourceforge.net/ Doing what supercollider does in smalltalk would be an insane amount of work at least for me. I try to minimise coding as much as possible and I am a big fan of code and tool reusageÂ and repackaging. So the only thing I am going to do is just make the gui for it. Of course my gui will offer limited access to the power of supercollider. I like to note here that I plan to avoid as much coding as possible with Ephestos because I know such a big project can become insanely demanding, so I don't want to reinvent the wheel. Gui designer wise, its funny because the part that does not interest you is exactly what interests me. I want to target with Ephestos not experienced smalltalk coders but users that have not done any coding in their lives and they are scared of starting it. I want Ephestos to be the 6 minute solution , 6 minutes will take you to figure out how to do something in it. So my goal is "Morpheas" a cut down version of Morphic, simplified, very well documented and very easy to use and understand with its own designers. I am considering using Athens and NBOpenGL for Morpheas will see how that goes. I really like Athens. Still I will try my best to build Morpheas on top of Morphic so you can still have your pie and eat it too.Â You are correct though most GUI designers out there do suck , but there is one exception ... Delphi / Lazarus and I am a huge fan of it. Unfortunately or fortunately i prefer dynamic languages like smalltalk and python from object pascal. Hence why I am trying to code for Pharo and not Lazarus. For the time being my sole focus is the interactive tutorial tool and figuring out how morphic works. Then will start working on Morpheas , which together with Proteas (IDE tools ) and Orpheas (the supercollider front end) form Ephestos. I dont want to overwhelm myself so I will just work on a single tool at a time and take it slowly step by step. But I will definetly keep you informed of my progress.Â ________________________________ From: Goubier Thierry <thierry.goubier(a)cea.fr> To: dimitris chloupis <thekilon(a)yahoo.co.uk> Sent: Monday, 10 December 2012, 17:25 Subject: Re: [Pharo-project] Unable to run pharo on Ubuntu 12.10 Le 10/12/2012 16:14, dimitris chloupis a Ã©crit : > Thanks for helping me out > > pharo -v > > pharo: command not found Ok.

Ok. A good suggestion then is, for audio synthesis and music composition, look at the work of Steven Travis Pope : he's done music synthesis tools in Smalltalk for a very long time (I met him in Paris around 1997/1998 and his tools were already impressive). For the GUI builder, I'm not too keen on that personaly. A gui builder is often a dumbing down of the underlying GUI toolkit, to be usable and general enough, and this is particularly true of Morphic which is a lot more advanced than Pharo shows it. In a way, the original Morphic has an integrated GUI builder... and the code is still there in Pharo and the GUI, but hidden. Still, I believe Spec is probably looking for help for that GUI builder. And, if I get to start it, I may propose some simpler Morphs which would work wonder with a GUI builder.

no I was not aware that it could not be done, worked fine for Macos (I am mostly a mac developer which is what I use at home, I use pcs only at work)Â so I assumed the same applied for Ubuntu I installed the package , still its unable to run it. Getting the same error I used the second answer to this question as a guide to install the package --> http://askubuntu.com/questions/107230/what-happened-to-the-ia32-libs-package " If you get that error, try: sudo apt-get update Then try it again: sudo apt-get install ia32-libs" I just did a fresh install of 12.04, that package is still available in the repositories.

[Pharo-project] strange == behavior
by Ciprian Teodorov Dec. 10, 2012

Dec. 10, 2012

Hi guys, Playing with some recursive data-structure I have found some strange piece of behavior in Pharo. If in an workspace we try to evaluate: a := Association new. a key: 3. a value: a. a == a value. the first time we get "true", the second we get an infinite loop... A simple workaround is to declare "a": |a| a := Association new. a key: 3. a value: a. a == a value. My question now is: Is this a bug or a feature ? By the way the same thing happens in 1.4 and 2.0 equally. By the way, in Pharo 2.0 doing cmd + . erases the lines selected in the workspace replacing them by "."

[Pharo-project] eating some obsolete dog food
by Nicolas Cellier Dec. 9, 2012

Dec. 9, 2012

This is a long time since I did not contribute to Pharo, so I tried with something easy... http://code.google.com/p/pharo/issues/detail?id=7108 I downloaded latest successful build, Pharo2.0a Latest update: #20433 Then I updated the 5 methods from a MC merge, and... Err... I cannot type my initials ^H^H^H^H^H^H^H^H full name The dialog insists on selecting any letter I type and next letter will override the previous one. I finally published anonymously, that does not matter... But you know the impact of a first bad UI impression... It would ruin tons of efforts I know you spent cleaning the infrastructure. I believe such cleaning is very ambitious and rarely rewarding in the short term... But I'd really like to be more supportive, it's so essential for building the future. So before ranting loud, I digged a bit further: could it be this warning I had at startup about obsolete VM, yes that was it! So if you are episodic user like me : ******** DON'T FORGET TO DOWNLOAD A PHARO SPECIFIC VM ************* I already spent way more time on this than I wished, hope my mistake helps someone else. ( over-estimating pharo planned obsolescence period is indeed a mistake ;) why would the VM be handled differently ? ) Last thing, maybe you should insist on the download page that 2.0 REQUIRES a pharo specific VM. Not sure I would have read it, but then it would be entirely my fault. Nicolas

[Pharo-project] Progress Update
by Camillo Bruni Dec. 8, 2012

Dec. 8, 2012

I promised to fix my partial refactoring for the ProgressBar. Finally this evening I hacked on the whole progress mess :), now I am almost done with one little bug left. - the progress bar is always responsive - all processes showing a progress with priority <60 can be interrupted - refreshes periodically 16 times per second - only forces a manual refresh when blocking the UI - no more out of bounds progress bars - no more ugly display buffer pattern when resizing the screen during a running progress this is a massive improvement for me :) For instance now you can simply interrupt the test runner with a click on the progress bar. I have one bug left, that is when I run the test runner, the UI event handling gets somehow disturbed. Windows no longer receive events, but everything is directly forwarded to the World. Opening the World menu is the only thing you can do :/ Anyone has a clue? The slice is in the inbox, see issue http://code.google.com/p/pharo/issues/detail?id=7103 best cami

[Pharo-project] [ANN] Pharo 2.0 enters BETA
by Esteban Lorenzano Dec. 7, 2012

Dec. 7, 2012

Hi, Today I finished the pending integrations for move to Pharo 2.0. There is still a problem with the VMs (for NB), but that's not a stopper for moving on. What does this means? Starting now, no new changes of API will be allowed, just bug fixes and minor enhancements that does not change the system behavior. We still have a long stabilization path until we can release, but we hope a couple of months will put us in shape :) Esteban
