Thank you for contributing to Nixpkgs! Could you read CONTRIBUTING.md and change the commit message to elixir: 1.5.1 -> 1.5.2? This helps us separate package updates from other kinds of changes, and estimate severity of the update at a glance.

So it looks like this has already been merged in master, but this does add a comment on how to generate the sha256 for contributors in the future.

Oops, indeed it has been updated in #31259. The comment is not particularly useful since you (1) can always update the version, alter the hash a bit, try to build the package and copy the hash from the hash mismatch error, (2) can often update the version and compute the hash with e.g. nix-prefetch-url '<nixpkgs>' -A elixir.src, and adding a comment about this generic technique into that file would be out of place.

Yeah, it was more for future me or contributor to be able to contribute instead of fumbling around to figure our how the hash is created.

Ahh I didn't know about: nix-prefetch-url '<nixpkgs>' -A elixir.src I am going to close this.
