Hi, I created a job to automatically generate a report of the Pharo image dependencies as well as current bootstrap dependencies. You can find them here: https://ci.inria.fr/pharo/job/Pharo-5.0-DependencyAnalysis/Dependencies_HTML... https://ci.inria.fr/pharo/job/Pharo-5.0-DependencyAnalysis/Dependencies_HTML... There are a lot (too many) dependencies but you can focus on some of them with the search field. Dependencies inside orange boxes are dependencies that are there but that we ignore (for example, an example method adds an extra-dependency). It should be fixed later but is not a problem for now. Ignored dependencies are declared in the package manifest in #ignoredDependencies. Dependencies inside red boxes are dependencies we want to remove for the bootstrap. For now, they are listed in the bootstrap dependency report. People that are willing to help to have a more modular Pharo could first take a look at the bootstrap dependency report and check dependencies that we should cut. Once we know, we can open issues on fogbugz in the 'bootstrap category' and update manifests accordingly. To investigate more deeply dependencies, you can use the DependencyAnalyzer (in the Pharo Catalog) to actually check dependencies (inheritance, reference, extension, traits, message send).
