iceberg

By committing the code to a git repo and having a code review like every other language out there. I'm guessing you have never tried these things but image based Smalltalk implementations have supported VCS for decades now, literally. In Pharo this is with git using Iceberg: https://github.com/pharo-vcs/iceberg They even wrote a tutorial to make it easier: https://github.com/pharo-vcs/iceberg/wiki/Tutorial It's not magic, it's not even a problem, because the problem you're imagining doesn't actually exist. So long as the user of the system has at least half a brain (and maybe less) they will be capable of distributing their code with git these days.

Iceberg for Pharo: https://github.com/pharo-vcs/iceberg Monticello: http://www.wiresong.ca/monticello/ I haven't used the latter, but the former is easy to use and based on libgit. Create a new repository, select the packages that go into it, make the initial commit. After that it'll tell you when the changes don't match the repo. You can select down to the method level since it's aware of the language's syntax and semantics. The generated repository looks like the Iceberg repo itself, a collection of directories for the packages and then .st files for the classes and their contents.

> a copy of your code the environment does some extra epicycles to copy it outside Iceberg https://github.com/pharo-vcs/iceberg is the Git/etc. integration built into Pharo and works extremely well. You don't need to "file out" code if that's what you meant.
