[Pharo-project] Call for your input on questions you ask yourselves during merge
by StÃ©phane Ducasse Dec. 1, 2011

Dec. 1, 2011

Hi guys We are writing some articles on the work of veronica to support merging activities. We need your input great smalltalk community :) What are the questions that you ask yourselves when you are/want to merge some code in your project? We would like to do a compilation of questions and also evaluate how the solution of veronica solves them or part of them. Here are some typical questions we asked ourselves. - What other changes did this change require? - Can I integrate this change right now? - How large it is? - Who made it? - Is it still valid (when I'm working on an old change)? - Is this change impacted by a change that happened in another branch of my software? Stef D., Andy K. and Veronica U.

[Pharo-project] Morph's #flags instVar
by Bernat Romagosa Dec. 1, 2011

Dec. 1, 2011

Hi list, In order to get Scat to be able to import Scratch projects, we'd need to add the 'flags' instVar to Morph, but whenever we try an error is triggered. Is there a reason for this behaviour? How can we get to add this variable? Thanks! -- Bernat Romagosa

[Pharo-project] fuel and a factory
by StÃ©phane Ducasse Dec. 1, 2011

Dec. 1, 2011

Just out of curiosity is there a way to specify the class that should be used when loading a fuel saved objects. For example I would like to know if it is possible to save Booleans and load them as instance of another class MBoolean of course boolean is a bit extreme :) but for a bootstrap we may need that.

But I missed that 0 was answering the executable name. It makes no sense for Smalltalk getSystemAttribute: 0 and Smalltalk getSystemAttribute: -1 to answer the same thing. I will change it (back) to 0 => executable name -1 .. -n => VM arguments *including* image (if explicitly supplied). and do so on all platforms. Thanks for spotting this. Alex > -- best, Eliot

Yes, i hit cmd . a couple of times! Regarding the Rome related classes, they are part of what should be cleaned out right? The same with Tweak. I've been planning to add Pango support, should i create a new repo, or put it alongside Athens? Fernando pd:What about moving to squeaksource 3?

[Pharo-project] Windows disappear in saved image on startup
by Larry Kellogg Nov. 30, 2011

Nov. 30, 2011

Hello, So, I have saved some Pharo 1.0 images, Pharo-1.8.image, for example, that contains a lot of changes that I have made, and packages that I have loaded. Now, when I bring up one of my saved images, I see all the windows the way they were for about three seconds, and then they all disappear. The image is still running but has none of the code I loaded. I tried to interrupt the image in startup (Command . on my Mac) but have been unsuccessful. Is there any way I can fix this problem? I have seven images that all display the same problem. I'm on Pharo 1.0 and running in an Amazon EC2 micro instance.

Re: [Pharo-project] Morphic replacement
by Fernando Olivero Nov. 30, 2011

Nov. 30, 2011

Thanks Sean, for now not much, once i release it would be nice if people try out the examples, run the tests, and hopefully prefer it over current UI frameworks and start building apps (widgets) on top of it, and helping me improve it. I'm kinda stuck with finding a name for it, because Gaucho is the name of IDE that will be built on top of it. Fernando On Mon, Nov 28, 2011 at 4:35 PM, Sean P.

[Pharo-project] New Cog VMs available at...
by Eliot Miranda Nov. 29, 2011

Nov. 29, 2011

VM.r2518/ <http://www.mirandabanda.org/files/Cog/VM/VM.r2518/>. CogVM binaries as per VMMaker.oscog-eem.139/r2518. Add access to VM arguments to Mac. Make Windows, Mac and Unix consistent: Smalltalk getSystemAttribute: -1 => executable name -2 .. -n => VM arguments *including* image (if explicitly supplied). Replace win32 command line parsing with unixesque code using CommandLineToArgvW. linux launch script: Cope with old linuxes use of /lib/tls hack for an optional thread-local-storage version of libc/libpthread. The launch scripts add /lib/tls:/usr/lib/tls: to LD_LIBRARY_PATH instead of /lib:/usr/lib: if the VM is linked to /lib/tls/libc. -- best, Eliot

[Pharo-project] Problem with NonInteractiveUIManager
by Norbert Hartl Nov. 29, 2011

Nov. 29, 2011

I'm trying to do some Katas in deploying pharo images on my server. After finding my image crashing all the time I tried to research what I need to take care of. I came to the conclusion that UIManager default: UIManager default nonInteractiveManager. NonInteractiveUIManager snapshotErrorImage: true. would be the right thing to do in a server environment. But I only get the stack trace attached. So I'm asking myself if I need to do something different in order to get the stack trace of my own application in case something goes wrong.
