Hi, currently we are fighting with several issues that make contributions to Pharo 7 much more complicated than we would like. Even in case you have no troubles with long paths (on Windows) nor SSH keys, it is now not easy now to start to contribute or review pull requests. Let's say you already have: - a Github fork of pharo-project/pharo repository - a local clone of pharo-project/pharo repository on your disk - this repository has a 'remote' pointing to your fork that is named by your GitHub user name During bootstrap the Iceberg registers a repository from which the image was bootstrapped and binds Monticello working copies history to it. This repository is hidden by default, to see it in the repositories list you need to enable Iceberg setting named 'Include system repositories by default'. If you will do it, you will see that this repository is red. You need to manually set the real path to you local clone (Edit). Then you should set your fork as default push target (in Iceberg: select 'pharo' repository - 'Remotes' tab - context menu on your fork remote - Make default push remote). It is good to synchronize your fork with the origin so it will contain recent commits on the development branch. You can do it by doing PULL from the origin (pharo-project/pharo) and PUSH to your fork. The alternative is to create a pull request from the original repository to your fork in the GitHub web interface and then let merge it) The next optional step is to checkout the particular commit hash from which the image was bootstrapped. It is optional because the Iceberg now supports cherry picking so you can avoid of committing changes you do not want. But to start your branches from a state when the image working copy is in sync with the git working copy is of course cleaner. Currently the bootstrapped image has some packages that are marked as dirty and it will make mess if you will try to commit your changes. You can avoid it by reloading of these dirty packages. This will be not needed in future. All these steps you can automatized by the following code. You need to at least customize your repository clone path and GitHub user name. It is supposed to be run only once on freshly downloaded Pharo 7 image. | location userName pharoRepository fork | location := '/path/to/your/pharo/repository'. userName := 'github-user-name'. Iceberg showSystemRepositories: true. pharoRepository := IceRepository registry detect: [ :each | each name = 'No name' ]. pharoRepository location: location asFileReference. fork := pharoRepository remotes detect: [ :remote | remote remoteName = userName ]. pharoRepository pushRemote: fork. pharoRepository pullRemote: pharoRepository origin. pharoRepository checkoutBranch: 'development'. pharoRepository backend pullFrom: pharoRepository origin. pharoRepository push. pharoRepository checkoutBranch: (SystemVersion current commitHash). [(pharoRepository savedPackages select: [:aPackage | aPackage isLoaded and: [ aPackage isModified ]]) do: #reload ] on: MCMergeOrLoadWarning do: [ :warning | warning resume: true ] As the result you should get a clean image based on the latest code that is ready to to create or review pull requests.
