cabal-install 3.10 has some quirky new logic for config, cache, … directory discovery. We reimplement this in this simple bash script, additionally respecting the CABAL_DIR environment variable.

# 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 a 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. Like cabal we only read the first output line and ignore the rest.)
|
|
# Those fields are specified under `upload` on the `cabal` man page.
