yes we should not use scriptLoader for that because scriptLoader should not be part of the default image. stef On Sep 21, 2009, at 1:40 PM, Laval Jannik wrote: > > On Sep 21, 2009, at 13:14 , Damien Cassou wrote: > >> On Mon, Sep 21, 2009 at 11:44 AM, Laval Jannik >> <jannik.laval(a)gmail.com> wrote: >>> I have just done a "ScriptLoader loadOB", and the same bug appears. >> >> Why do you use this old and not working script when I'm generating >> new >> images three times a month? > > because it is present in the image :) > > If it is an old version, maybe we must clean ScriptLoader. > > >> >> http://pharo-project.org/pharo-download >> >> -- >> Damien Cassou >> http://damiencassou.seasidehosting.st >> >> "Lambdas are relegated to relative obscurity until Java makes them >> popular by not having them."

how did you load it because it works for me when I open it using the mc browser drop it into the package-cache.

Re: [Pharo-project] Gofer vs Installer

This is something that I can't understand. Is this supposed to be a package management system per se, a la Metacello, aptitude, yum?? Isn't just a installer of MC packages but tries to manage the MC database of packages in a way that is clean and *atomic*? So, there will be a registry of gofer installed operations so that can be utilized after the install operation (maybe months later)? Or will just be for trying to install some group of packages and if some error happens immediatly revert? Can you relate the scenarios showing how gofer is intended to use, because until now (maybe my narrow perspective) the examples shown can be done also with ScriptLoader and Installer. Other thing, I tried to convert my image install script but I can't finish because I install packages from monticello configurations (magma 1.0r42) and from my local directory repository. Neither of those options can be handled by gofer (as far as I can see). Of course this can be corrected, it is just to integrate the correct MC installer classes. That reminds me other thing, Installer can handle monticello configurations, is the corresponding way of loading the packages using gofer to list each package in the mcm file in a gofer script? So mcm will not used or it is just that there have no been time to add those capability to gofer? Thanks -- Miguel CobÃ¡ http://miguel.leugim.com.mx

Hi all, I've changed the new setting implementation. The new proposition is attached. I think that this implementation is in sync with Lukas remarks; and yes, I think it is much better now, thanks! I also removed PragmaHandler and SettingHandler classes as Stephane suggested. It temporarily includes several (stupid) examples for testing purpose. Comments have not yet been changed. I will do it asap. Remarks, comments etc are welcome. Cheers Alain Lukas Renggli a Ã©crit : >> - A setting with value is an instance of SettingValue or of one of its >> subclasses.
