[Pharo-project] How to execute code before and after a package is load?
It need to turn off system notifications for TestCase while gofer updates SUnit. One way I see would be to execute some code snippet before and after loading. However the Script button in Monticello seems to be broken. I cannot add scripts to the package. What can I do? So the current way to load akuhn SUnit is [SystemChangeNotifier uniqueInstance noMoreNotificationsFor: TestCase. Gofer it displabePackageCache; squeaksource: 'akuhn'; package: 'SUnit'; package: 'SUnitGUI'; load ] ensure: [ TestCase initialize ]. which is well ... quite ugly for a Gofer script. --AA
To obtain the after behavior, the classical way is to define an 'initialize' method on the class side of one your class. Cheers, Alexandre On 29 Dec 2009, at 04:09, Adrian Kuhn wrote:

I **never** used scripts. I have no idea what they are (even if I guess) and more important the door that they open into a space that we do not control is dangerous. (Imagine people publishing a hell of scripts with no tool and metamodel support for them). So please do not use them. Use the model with have, class, method, package. In metacello there is a preload and postload if I remember. May be Gofer should have a silent: #TestCase

They are pre- and postload code snippets. If you add 4 missing methods on package info you get them in monticello (but sometimes they seem not to execute when loading a package, so I gave up at that point...)
In metacello there is a preload and postload if I remember.
How do I use metacello, any documentation / tutorial available? cheers, AA

http://code.google.com/p/metacello/wiki/Tutorial I would recommend the "Image-based Tutorial". If you want more examples you can check the http://www.squeaksource.com/MetacelloRepository Yes, Metacello does support post and pre doits but the problem is that it is only at package level, not project. Dale is aware of this and already put in his todo list to have pre a post scripts for a whole project. A simple hack is to put the post script to the last package. Cheers Mariano
