- updateScript: A nix expression that can be used in passThrough to update a package - list-git-tags: A shell script to list available tags in a git repository - list-archive-two-level-versions: A shell script to list available versions in a web site in two levels: there is a page listing the available major.minor versions, and for each of them there is another page listings the patch level versions major.minor.patch. It is suitable for Xfce packages for instance. How the updater works: 1. collect the available versions from the source repository (using a script given as argument) 2. print the collected versions (for debugging) 3. (optionally) apply some transformation to the collected versions to make them compatible with the versions used in nixpkgs (for instance, tags in the Xfce git repository may be prefixed with the package name, and the prefix need to be removed) 4. sort the available versions in decreasing order 5. choose the first version that pass validation: - check if the version may be a development version - if the version IS unstable, skip it and give a warning about skipping a development version (for debugging) - if the version COULD BE unstable, take it and give a warning about taking a potential development version (for debugging) - if the version IS stable, take it 6. update the package version and checksum in its nix expression 7. print the git commands for adding the modified files and for committing the changes
