(Kind of urgent) Phratch: operators don't work at all on last verion!

by Offray Vladimir Luna CÃ¡rdenas

Hi all, Today we started to use phratch to a group of people without much of any experience with computer programming. The idea is to have a workshop today and tomorrow start with more symbolic and abstract approach using Pharo and give them a taste of the several levels of programmig and exploration this environment provides. But my main problem is that operators dont work on Phratch. We get a MNU as soon as we select the operators button which is a real stoper for any advance stuff. We're using the currently available package from the download page. Can somebody help me on this? Also: Â¿How can we erase a line drawn with the pencil on the background? I will be sharing more questions as they come. Thanks, Offray

Re: [Pharo-users] PharoJS

What is PharoJS ? Are you talking about Pharo on top of the Bert's SqueakJS VM ? If so, it starts, but some primitives fail making it freeze after a short while as you describe. It would be fun to have it running even though most of the Pharo folks went into the Amber direction for Pharo on Javascript. 2015-07-14 19:46 GMT+02:00 Esteban A.

Copy-Paste form external sources does not work on Windows 8.1

by Dominique B.

Hi dear all, I am currently taking a couple of tutorials on Pharo and I noticed that cutting and pasting code snippets from the web, pdf, notepad, ... to Pharo 4.0 was not working on my Windows 8.1 installation. I double checked that versions 3.0 and current 5.0 exhibited the same behavior on 8.1.I double-checked this problem does not manifest on Windows 7. Am I the only one to experience it?Thanks in advance,Â Dominique

yesâ¦ I introduced that problem in Pharo 5.

Re: [Pharo-users] Saving image sometimes corrupts it

by Blondeau Vincent

Hello, I have the same problem and it seems to be random. It is related to font cache. I opened a bug related to it: https://pharo.fogbugz.com/f/cases/15944/Image-crash-on-Pharo-due-to-fonts-o… I will raise the priority because it is very painful... I am at ESUG too maybe we can discuss of it ;) Vincent Blondeau ________________________________________ De : Pharo-users [pharo-users-bounces(a)lists.pharo.org] de la part de Jan BlizniÄenko [bliznjan(a)fit.cvut.cz] Date d'envoi : mardi 14 juillet 2015 11:38 Ã : pharo-users(a)lists.pharo.org Objet : [Pharo-users] Saving image sometimes corrupts it Hello I come with another probably-only-mine-windows-related problem which I am unable to reproduce from a clean image. I use latest image 50170, latest (9th July 2015) Windows VM, Windows 7 64bit. So there is my vague description: When I load some project, modify it few times and save it, then SOMETIMES (seems random to me) when I try to open this saved image, it immediately crashes VM and does not even produce crash.dmp file (well, it creates it, but empty). For example, I have such image... I save it, do not close it, try to open it, crash, save it again, try to open it, it runs, save it again, close, try to open it, crash. Without any change inside the image by my hand. I tried doing something similar with clean image, but it never corrupted it. I am unable to open such image even on my Linux machine. It at least generates output when segmentation fault happens: http://pastebin.com/KLry40Hu HDD I am saving it to does not show any signs of damage, everything else is working (and saving) just fine. Here is such crashing image: http://www.mediafire.com/download/h5vhh7c40cl1w15/Pharo+5.0+%28beta%29-5017… and here is the same image saved again which runs fine: http://www.mediafire.com/download/86djppsn1ds3c0o/Pharo+5.0+%28beta%29-5017… However, when I open this "ok" image in linux, it causes segfault too. I tried also opening working image in VM marked as stable (2015-09-24), then I saved it and there was the same problem. This is probably all I know about it, although I am aware that it is not much, but I am in the dead end and this problem is really huge for me. I am on ESUG so if you are here too and think you might be able to help, I can show it to you personally.

Re: [Pharo-users] Pharo on 64bit Ubuntu

by Leo Noordhuizen

Markus, If you read the messages in this thread, you can see that it has been more or less solved. 'More or less' because Pharo runs fine now, but when I reboot Ubuntu I get a systemerror with as subject Pharo-vm. This has been probably caused by my different attempts to make this work (with different methods) which may have left some 'rubble' causing this. I should probably re-install Ubuntu soon. Which I do now and then anyway.
