I'm not sure there is a documentation of this API, but looking at the source code is *very* easy: - download a SmalltalkHub image: https://ci.inria.fr/pharo-contribution/job/SmalltalkHub/ - open the image - look at ShHandler, ShVersionsHandler, and all Sh*Handler - all the methods with a <get>, <delete>... pragma is a REST entry point. You can also, open the web console of your favorite web browser and look at the network messages. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Yes, additional files are not of a problem while loading. Problem is that they are not preserved, so when I open the package in unmodified pharo and save it again, all extra files are gone. That's no-go for me :-) Jan > > On 2013-05-29, at 02:01, Jan Vrany <jan.vrany(a)fit.cvut.cz> wrote: > >> Hi there, >> >> I need to store a sort of a metadata along with the code >> in the .mcz.

SmalltalkHub browser ?

by laurent laffont

Hi, I would like a sort of dedicated metacello browser for SmalltalkHub that only shows my projects & watch projects on SmalltalkHub. So the scenario is: - open SmalltalkHub browser - first time enter login & password - voilÃ , all my projects can be downloaded & saved (no more add repository, add to package, .... bla bla bla). - select a project / package in the browser -> open in nautilus I ask that because I had to evaluate many projects of my students in different repositories & packages, tiring :) Is there's an ongoing project for that ? If not, is there an API for SmalltalkHub to get needed data ? Cheers, Laurent

So, what do we do ? - Don't model and don't track overrides, even if some packages are effectively using them. - Model overrides so that we can: - Detect when a package is creating an override (a Lint rule?) - Signal an error for an override of an override (upon loading, for example). - Signal an error when updating a package changes an extension to an override.

Is it important to classify overrides as such, or just let them be extensions ? The thing is that overrides don't work. As soon as 2 packages override the same method ==> which one is it? Therefore, overrides as a *concept* make no sense. And thus modeling them makes no sense. Nobody ever should do overrides, because it will just not work as soon as it is used a lot. Marcus

Yes, that is very much needed. We should do that, at least as an option.
