Because is cleaner and as the releases of Pharo diverge a lot more, the code to install package becomes full of conditionals to handle the distinct issues with each pharo release. For example, Magma. Magma 1.1r1 worked good in any pharo 1.0, 1.1 and 1.2. But Magma 1.1r2 doesn't work anymore on Pharo1.0 because Pharo 1.0 doesn't have the classes DirectoryEntryDirectory and DirectoryEntryFile that are used by the new magma version. So I had to modify the configuration with conditionals an several variations of preDoits and postDoits and test what version image is ConfigurationOfMagma is being ran. After a couple of hours I gave up. The correct solution is to have a specific ConfigurationOfMagma for each released pharo version. This have benefits also: - It permits the unstable repository to heavily update the ConfigurationOfXXX without disturbing or broke the stable ones. - It permits the ConfigurationOfXXX code to remain clean, without a conditionals for every posible combination of release image version and package to be installed version - It permits the maintainer of a ConfigurationOfXXX to decide when to stop supporting old version of a certain package by deleting the old versionXX: methods of the ConfigurationOfXXX in the newer pharo releases. Not always is good to be able to install each and every version of a package in the newest release of pharo (maybe even old versions won't work in the new releases, like the menu registration issue or classes that doesn't belong to the core image) - It permits to issue maintenance ConfigurationOfXXX releases for a stable or "old-stable" image releases, without altering the configurationOfXXX in other repositories Cheers > > 2010/8/4 Miguel Enrique Cobá Martínez <miguel.c...@gmail.com>: > > El mié, 04-08-2010 a las 11:46 +0200, Torsten Bergmann escribió: > >> Hi Miguel, > >> > >> hey, nice!
