First, let me say that we really appreciate your project and we are happy with it :) Now, to avoid reinventing the wheel, I want to point you some stuff. 1) There is a GlorpDBX connection pool available. This is the package GlorpDBX-ConnectionPool. Documentation: http://www.squeakdbx.org/documentation/SqueakDBX%20connection%20pool%20for%… 2) There is a general purpose pool (for any kind of object) that also work in Glorp or DBXTalk. http://www.squeaksource.com/ObjectPool There is a package ObjectPool-GlorpDBX :) I cc'ed Panu, the developer.

I will take a look. For the pools, the expert is Diogenes and Panu :) Best regards, -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-users] Parsing XML into sorted elements

Anyone have anything better? > Why do need to sort while the parser is parsing? Can't you sort just afterwards? I think this is the cleanest approach. If you want to sort the elements immediately than you need custom classes like you wrote. Did you have a look at XMLPluggableElementFactory ? You can set a nodeFactory in the XMLDOMParser that should emit your classes while parsing. In your custom class there should be a possibility to override nodesClass in a clean way to get the list changes done. If not that would be a needed enhanced to the parser. Norbert

I think, the more you know the system, the less you use the finder ...

Browser Panes (or is it Pains??)

by Tony Giaccone

I downloaded squeak to try out the UI Generator created by the Haso Plattner Institiute. When I did that I noticed that the squeak system browser has a feature that solves one of my constant annoyances in pharo. The panes of the browser are re-sizeable in the x direction. I can make different panels different sizes. Is there a setting or someway to easily add this capability to the Pharo System Browser? Tony Giaccone

Actors library

by Alex Schenkman

Hi list, Is there an Actors library already available in Pharo? The part I'm interested in is the asynchronous message passing. If it has been done already, why not reuse? Thanks in advance!
