Hi dale I implemented a little tool that - create a kind of specification (version, package, repo) for all the packages reachable from a configurationOf (see below method method packagesAndAssociatedRepositoriesFromConfigurationRecord ) It generates a script looking as follows: script3 ^ #( #('ConfigurationOfFame-TudorGirba.5.mcz' 'http://www.squeaksource.com/Fame/' 'ConfigurationOfFame' ) #('ConfigurationOfMooseAlgos-usmanbhatti.27.mcz' 'http://www.squeaksource.com/MooseAlgos/' 'ConfigurationOfMooseAlgos' ) #('ConfigurationOfGlamour-TudorGirba.98.mcz' 'http://www.squeaksource.com/Glamour/' 'ConfigurationOfGlamour' ) #('ConfigurationOfDSM-AlexandreBergel.56.mcz' 'http://www.squeaksource.com/dsm/' 'ConfigurationOfDSM' ) #('ConfigurationOfKumpel-AlexandreBergel.3.mcz' 'http://www.squeaksource.com/Kumpel/' 'ConfigurationOfKumpel' ) #('ConfigurationOfSmallDudâ¦â¦â¦â¦.) - I keep the order given by Metacello. I extract the information as follows: packagesAndAssociatedRepositoriesFromConfigurationRecord: aConfigurationRecord "| record | record := ((Smalltalk globals at: #ConfigurationOfMoose) project version: 'default') ignoreImage: true; record. self packagesAndAssociatedRepositoriesFromConfigurationRecord: record " | pkgs | pkgs := OrderedCollection new. aConfigurationRecord loadDirective packageDirectivesDo: [:directive | pkgs add: {directive spec name, '*'. (self removeCache: directive spec workingCopy repositoryGroup repositories) anyOne locationWithTrailingSlash} ]. ^ pkgs - then I try to load the package as follows: flatVersion47: spec <version: '4.7-flat'> spec for: #common do: [ self populateSpec: spec with: self script3 ] I load them doing (ConfigurationOfMoose project version: '4.7-flat') load Now It does not work because after fetching all the packages, the system complain that some classes that will be loaded later are not present. I imagine that you use Gofer and that Gofer does not use the merging semantics of MC over multiple projects (that you can have multiple package in any order and that the classes get loaded - as I use it for the scriptLoader and below). - before I was doing it by doing a diff between the pharo package and the one loaded and I was loading the specification after installing the repository and the working copies using the MCVersionLoader and it worked I could reload completely Moose! load: aCollectionOfPackageString "self new load: #( 'Famix-C-TudorGirba.15' 'Famix-Core-NicolasAnquetil.201'))" | loader | loader := MCVersionLoader new. (self newerVersionsIn: aCollectionOfPackageString) do: [ :fn | loader addVersion: (self loadVersionFromFileNamed: fn). (Delay forSeconds: 2) wait.] displayingProgress: 'Adding versions...'. loader hasVersions ifTrue: [loader load]. So my question is - Does the packageDirectivesDo: provide an order that I can use to load package with the gofer-load on project at a time? May be my code does not keep the same order but I payed attention to this point. I will check that further. - may be I could extend Gofer to support multiple project merge loading. So right now I'm stuck and this is sad because freezing a complex configuration is really needed. Stef
