Re: [Pharo-users] Ring package, when to use it?

by Juraj Kubelka

Thank you Marcus for the explanation. So now I understand that if I want to analyse existing packages/class/methods/etc in the image, Ring is not a kind of interest. But as I think about it, if someone uses Ring as a base to analyse environment, then it could be useful to use the same analysis tool for any source, e.g. not loaded packages. Am I right or are the some limitations? Thanks.

This is really cool! How does SQLite scale in terms of table size and so on? I was surprised to know it is based on an old version of PostgreSQL according to this presentation: http://www.pgcon.org/2014/schedule/events/736.en.html Regards! Esteban A.

This is needed often and everyone implements their own model: Monticello (MCClassDefiniion), FilePackage (Pseudoclass/PseudoMethod), RB (RBClass, RBMethod). Ring is a first step to propose one model that everyone can use who needs to model code that is not installed in the system. e.g. if you want to analyse and mcz package, instead of loading it (with all the side effects), you could load it as a Ring model. Like everything that exists it is not perfect (else it would not exist)... e.g. we actually should replace PseudoClass and PseudoMethod by Ring, for example. Any improvement (both to the model or its use) are very welcome. E.g. one thing I am slowly doing is to simplify it (e.g. removing the RGFactory class) Marcus

Glorp + NBSQLite3

by Pierce Ng

Hello, I am pleased to report that I have gotten Glorp working with NBSQLite3 enough to run Sven's Reddit.st. As mentioned in my blog post, there is more work to be done to get Glorp fully integrated with NBSQLite3, but preliminary results are encouraging. http://www.samadhiweb.com/blog/2014.09.24.glorp.nbsqlite3.html Pierce

Ring package, when to use it?

by Juraj Kubelka

Hi! I am trying to understand in what scenarios is good to use Ring package instead of objects of compiled methods, classes and r-packages. It is not clear to me. For example if I want to ask for where a method/class/package is referenced should I consider the Ring package? When I should consider to use Ring? Thank you a lot, Juraj

It looks interesting but requires the user to install 0install before being able to install Pharo. A big drawback ...

Right click on the app and click Open. This time around it will bring up the same screen but with a second button that says Open. After you click that it will never ask again.

Mac VM - developer unidentified

by Usman Bhatti

Hi, Today I downloaded Pharo vm from pharo.org. When I try to open the VM I get this security notification from Mac and it didn't happen with earlier versions of Pharo VM. I'm running: OS X 10.9.4 (13E28). [image: Inline image 1] I should be able to change my security settings to run it but I prefer not to and for less knowledgable it can be a negative message. regards, usman
