Package search says package exists in 22.05, but nix-shell doesn't find it

1

According to the search page, hatch-fancy-pypi-readme is in 22.05. However, when I try to refer to it as self.hatch-fancy-pypi-readme in a poetry2nix override, nix-shell says

error: attribute ‘hatch-fancy-pypi-readme’ missing

What gives? It looks like hatch-fancy-pypi-readme was introduced to 22.05 after release, because there’s no reference to it in commit ce6aa13369b667ac2542593170993504932eb836. Is that normal? And if that is the case, how do I figure out which commit to pin to to get the latest version of 22.05?

To test, use the following poetry.lock:

Seems like you need to upgrade your nixpkgs commit, the package was added on 1st September anl your commit is from 30 May.

Looks like you’re right. Based on an older script I’ve come up with a script to get the current version of a particular channel:

#!/usr/bin/env bash

set -o errexit -o nounset -o pipefail
shopt -s failglob inherit_errexit

if [[ $# -ne 1 ]]; then
    cat >&2 <<EOF
bump-nixpkgs.bash: Update nixpkgs.json with latest info from given release

Usage:

./bump-nixpkgs.bash RELEASE

Example:

./bump-nixpkgs.bash 22.05
    Bumps nixpkgs within the 22.05 release.
EOF
    exit 2
fi

release="$1"

cleanup() {
    rm --force --recursive "$working_dir"
}
trap cleanup EXIT
working_dir="$(mktemp --directory)"

intermediate_file="${working_dir}/1.json"
full_file="${working_dir}/2.json"
target_file=./nixpkgs.json
curl "https://api.github.com/repos/NixOS/nixpkgs/git/refs/heads/release-${release}" |
    jq '{name: (.ref | split("/")[-1] + "-" + (now|strflocaltime("%Y-%m-%dT%H-%M-%SZ"))), url: ("https://github.com/NixOS/nixpkgs/archive/" + .object.sha + ".tar.gz")}' >"$intermediate_file"
jq '. + {sha256: $hash}' --arg hash "$(nix-prefetch-url --unpack "$(jq --raw-output .url "$intermediate_file")")" "$intermediate_file" >"$full_file"

if diff <(jq 'del(.name)' "$full_file") <(jq 'del(.name)' "$target_file"); then
    echo "No change; aborting." >&2
else
    mv "$full_file" "$target_file"
fi

Not exactly the simplest solution, but I didn’t find anything else.

Now you have flakes that can upgrade the inputs with a simple command ^^
