Re: [Pharo-users] Making objects persistent

Sergio, I'D say you first need to define what you mean by "persistent" If all you need is to have them survive a Garbage Collection, you just need to make sure these objects are referenced by som eother objects. Depending on your use case, this can be Seaside Sessions, Global variables (probably the worst idea), TestCase subclasses or even a TestResource. If you want to persist them for longer, we are talking about storage of objects, which is another beast. What comes to mind are options like Fuel, STON, Json, Voyage/Mongo or Glorp with some Database - the choices are endless.

Could we keep Pharo-dev for Pharo-dev?

by stepharo

Hi guys I will start to be picky about the mails to which I reply or even read. We should be more disciplined. Pharo-dev should be about Pharo-dev this is important for our concentration. I really like the other discussions but we should have them in Pharo-users. I think that it makes sense. Stef

Re: [Pharo-users] How to keep the system updated?

by stepharo

Hi laura The update mechanism is sometimes updating part of the systems that are currently used and hence it is difficult to control what is happening. What I suggest is to download new version using the PharoLauncher or scripts Stef Le 15/1/15 05:30, Laura Risani a Ã©crit : > How do i keep the system updated?

Making objects persistent

by sergio_101

I am building a seaside application, and am in the process of building my models and unit tests. I have a few objects that build up my data by creating objects. when i run the data creation methods, everything is fine. immediately afterward, since these objects to belong to anything, they are cleaned up by garbage collection. is there a way to create these objects so that they persist? if this is possible, how would you go about deleting such a tenacious object? thanks!

How do i keep the system updated? Should i just wait to the next version release or should i do something in the the midtime?

Re: [Pharo-users] Useful tools?

by laura

i'm afraid i posed the question too broadly to be answerable, so reformulating... What are some tools you frequently use to ease development which are neither built in the current official distribution nor domain-specific? (for example i added TilingWindowManager, RBConfigurableFormatter, many shortcuts ) Some Class Browser plug-in? I've tried adding PackageTasksPlugin beacause i found the idea interesting, but it doesn't work properly, a Predebug window keeps showing each time i move to another package. -- View this message in context: http://forum.world.st/Useful-tools-tp4799187p4799636.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Becoming proficient in Pharo

by kilon alios

you asked and I delivered. A video tutorial on the debugger , deeper into live coding and a powerful tool to understand the internals of objects and their structure https://www.youtube.com/watch?v=ZE2T2D8hikE I will of course follow it with additional tutorials since its a rather big subject but this tutorial should be more than enough to get you started and make you dangerous with Pharo. Always remember to save images before changing code , for example a self halt inside Morph initialize method was more than enough to freeze my image.
