Hi. For building PharoDev images, we take a PharoCore and just evaluate something like: (ConfigurationOfPharo project version: '1.1-beta1.10517') load So....Metacello would be boostraped from ConfigurationOfPharo>>ensureMetacello which does a (Smalltalk at: #ConfigurationOfMetacello) perform: #loadLatestVersion and ConfigurationOfMetacello>>loadLatestVersion does a "self project latestVersion load" ... and, the default of ConfigurationOfMetacello is Core....so, in summary, only core is loaded. Perfect. Now I was thinking that we should load more packages in PharoDev image. First, we want the Metacello tests. For all packages we include by default in PharoDev, we also include its tests (by default). This is cool because people test it, we can give you quick feedback, be sure all green tests, etc. They are cool as documentation, blah blah blah. So, first question, which tests package should I load? Metacello-Tests Metacello-TestsCore Metacello-TestsMC Metacello-TestsPlatform.pharo Metacello-TestsReference Or, maybe even better, load the group 'Test'. I guess this is the correct one. Now, I also think we could include all the following packages: - Tutorial: this is cool for newcomers. They want to do the Metacello tutorial, and having it already in the image is cool I think. I want to include also the tests for the tutorial - HelpSystem for Metacello: we need to copy this package from the HelpSystem repo (see my other email) - Metacello ProfStef - Metacello OB: do you know if it is working in Pharo 1.1 and with OB 1.1.4 ? What do you think about including these packages in PharoDev by default ? I think it is a good idea. Regardless that, I am not sure how to load them. As I told you, when building PharoDev images, Metacello is boostraped from the #ensureMetacello of ConfigurationOfPharo. And this will load the Core. ANd this is correct because other people use COnfigurationOfPharo for their own stuff and they just want the core. But in the case of PharoDev, I want more packages. But modifying #ensureMetacello is not an alternative. So...I can put a reference to ConfigurationOfMetacello in Conf of Pharo, just like any other dependency, and there I specify the loads: with the array of things I want. This seems better. But I still have a problem: #ensureMetacello will load the latestVersion of it. It will load core. So, which version of ConfigurationOfMetacello should I use in my version of ConfigurationOfPharo. If I put a specific version, I may hve problems because it will try to download different versions....So, I would like to load the same as the #ensureMetacello. But I cannot specify in version method lastVersion for metacello. what can I do ? don't specify the metacello version in the version method so that it takes the last one ? Thanks and sorry for the long email Mariano
