# On Hackage every package description shows a category "Distributions" which
# lists a "NixOS" version.
# This script uploads a csv to hackage which will update the displayed versions
# based on the current versions in nixpkgs. This happens with on simple http
# request.
# For authorization you just need to have any valid hackage account. This
# script uses the `username` and `password-command` field from your
# ~/.cabal/config file.
# e.g. username: maralorn
# password-command: pass hackage.haskell.org (this can be any command, but not an arbitrary shell expression.)
# Those fields are specified under `upload` on the `cabal` man page.

After merging, **make sure not to delete the `haskell-updates` branch**, since it
causes all currently open Haskell-related pull-requests to be automatically closed on GitHub.
## Update Hackage Version Information
After merging into master you can update what hackage displays as the current
version in NixOS for every individual package.
To do this you run `maintainers/scripts/haskell/upload-nixos-package-list-to-hackage.sh`.
See the script for how to provide credentials. Once you have configured that
running this takes only a few seconds.
## Additional Info
Here are some additional tips that didn't fit in above.
