At least looking description on their web site, there is a cool integration with Moose/Famix. My package is at POC stage right now, probably far less elaborated and more oriented towards runtime checking and debugging than contract designing . Very interesting, I'll digg into that. Thank you for the pointer -- Alain

changes in garage config

by Usman Bhatti

Hi, I changed ConfigOfGarage to make the stable load in Pharo 4. Stable now loads Garage-OpenDBX-VincentBlondeau.24, before there was no version specified for the package. Name: ConfigurationOfGarage-usmanbhatti.17 Author: usmanbhatti Time: 26 February 2016, 1:31:24.092763 pm UUID: ae741a54-d2c6-4bce-bfdd-52b71653f217 Ancestors: ConfigurationOfGarage-EstebanMaringolo.16 making stable load in pharo 4.0 and stable 0.4 is now Pharo 4-specific.

(cf http://www.oracle.com/us/technologies/java/assertions-139853.html "...The program will be aborted if the expression evaluates to false..") With java it is possible, since the IDE and program are separated. With Pharo you cannot, if you assert or throw an error in a sensible place, you are likely to hang your image or to go for multiple errors poping everywhere since you will break the state of an important object. Another thing is that with dbc paradigm (assertions about your code), there is no 'one invariant' but lots of, you will not be able to express them in a single method, even if you could it would be hundreds lines and you would have to copy them in all methods you will want to check. The complete horror to maintain when you change your code. The use of pragmas make it possible to activate or deactivate those contracts at compilation time, there will no overhead in standard execution without contracts. Think of the pragmas as a way to "inject" invariant compiled code into the compiled method for testing, then you recompile without for release. Adding invariants will have *big* performance impact, probably several orders of magnitude, I'll measure. The overhead will of course come from calls of the checking framework, but no doubt that with run-time reflexivity checking, you will have something as sluggish too and you'll want to deactivate them at compile time ... I'm ready to bet on that one beer ... :) -- Alain
