Hi guys, It is a project from Noury - at the Mines school. Just do a google for Noury and PharoJs I found out about it from Torsten's blog - always worth reading :-) AIUI, what it does is convert Pharo code - in the fly - to JavaScript. I can't say much more because I haven't got it to run. However, it is on small talk hub, so ease give it a go.

Saving image sometimes corrupts it
by Jan BlizniÄenko July 14, 2015

July 14, 2015

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. Jan BlizniÄenko

Copy-Paste form external sources does not work on Windows 8.1
by Dominique B. July 14, 2015

July 14, 2015

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

SubscriptOutOfBounds: 0 in blocks evaluating nil
by Jose San Leandro July 14, 2015

July 14, 2015

Hi, I'm experiencing an issue when using whileFalse:, in Pharo 4. I've just looking for opened bugs in pharo.fogbugz.com but I don't see any matching my problem, apparently. In the following example, I get a SubscriptOutOfBounds: 0. Object subclass: #WhileFalseIssue instanceVariableNames: 'myFlag' classVariableNames: '' category: 'MyTests' WhileFalseIssue>>attemptUninitialized [ myFlag ] whileFalse: [myFlag := true ]. ^ myFlag. WhileFalseIssue>>attemptInitialized myFlag := false. [ myFlag ] whileFalse: [myFlag := true ]. ^ myFlag. Calling attempt like this: WhileFalseIssue new attemptUninitialized. launches the debugger with "SubscriptOutOfBounds: 0" (see attached screenshot), whereas WhileFalseIssue new attemptInitialized. works fine. Should I file in a bug in fogbugz? I will try with Pharo 5. Kind regards, Jose.

how to extend GTSpotter to handle XMLs
by Tudor Girba July 12, 2015

July 12, 2015

Hi, The default search options that come with GTSpotter are nice, but the power of a moldable tool like GTSpotter stems from how it can be extended by external packages. To get an idea of how this works in practice, you can find an example of how to make GTSpotter to extend the search through files with the ability of diving in an XML file in the XMLParser project. For example, the screenshot shows that we dived in an XML file, and in that file we can directly search for XML elements: [image: Inline image 2] Here are some more details of how this works: http://www.humane-assessment.com/blog/searching-xml-with-gtspotter/ Remember that GTSpotter competes at the ESUG Innovation Awards :).

Starting TWM
by Sean P. DeNigris July 12, 2015

July 12, 2015

TWMBar's class comment says, "Open with: TWMBar new open.", but the setting does "TWMBar showTWMBar: true". Are they equivalent? Or should something be updated? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Starting-TWM-tp4837025.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

PharoPro support for companies and business has as sole objective to make Pharo a strong and reliable choice for developing business critical applications. PharoPro will make sure that Pharo companies can fulfill their needs using Pharo as a platform for business. Offering this new service will bring Pharo to another level of business acceptance. We propose to offer it in the umbrella of the Consortium. We sketch the PharoPro services here: http://consortium.pharo.org/web/pharopro <http://consortium.pharo.org/web/pharopro> We worked hard to on it and we will be at ESUG to discuss with you about business opportunities. Do not hesitate to send us feedback about your needs! Esteban, in behalf of Pharo Board

<example> pragmas and example* methods use-cases
by Peter UhnÃ¡k July 9, 2015

July 9, 2015

Hi, there was a long discussion about the meaning of example* methods and <example> pragmas, however I do not know what was the final resolution. Basically I am interested in two use-cases 1. executable example (the one where Nautilus shows nice play icon) This is as I understand only through example* naming (on class-side). 2. returning examples (example that returns some value that I can reuse) Is this what <example> pragma is for? How would I go about naming it considering that having play icon there would be counter-productive (user would be clicking on it and nothing would happen). Thanks, Peter

Meta repo for pharo 5.0 / pharo catalog
by Norbert Hartl July 9, 2015

July 9, 2015

I just added the class side information to my metacello configuration in order to have it displayed better in the pharo catalog. In the pharo catalog it says that my package (mustache) has not been tagged for pharo 5.0. I don't know how this information is derived. And I cannot see a meta repo for pharo 5.0 where I can put the configuration. Has this process changed. Are there any pointers I can get information about. Thanks Norbert
