maintainers/scripts: add get-maintainer-pings-between.sh

Sometimes it is useful to see which maintainers your change will ping,
to know who you are going to spam in advance.

Maintainer scripts

This folder contains various executable scripts for nixpkgs maintainers, and supporting data or nixlang files as needed. These scripts generally aren't a stable interface and may changed or be removed.

What follows is a (very incomplete) overview of available scripts.

Metadata

`get-maintainer.sh`

get-maintainer.sh [selector] value returns a JSON object describing a given nixpkgs maintainer, equivalent to lib.maintainers.${x} // { handle = x; }.

This allows looking up a maintainer's attrset (including GitHub and Matrix handles, email address etc.) based on any of their handles, more correctly and robustly than text search through maintainers-list.nix.

❯ ./get-maintainer.sh nicoo
{
  "email": "nicoo@debian.org",
  "github": "nbraud",
  "githubId": 1155801,
  "keys": [
    {
      "fingerprint": "E44E 9EA5 4B8E 256A FB73 49D3 EC9D 3708 72BC 7A8C"
    }
  ],
  "name": "nicoo",
  "handle": "nicoo"
}

❯ ./get-maintainer.sh name 'Silvan Mosberger'
{
  "email": "contact@infinisil.com",
  "github": "infinisil",
  "githubId": 20525370,
  "keys": [
    {
      "fingerprint": "6C2B 55D4 4E04 8266 6B7D  DA1A 422E 9EDA E015 7170"
    }
  ],
  "matrix": "@infinisil:matrix.org",
  "name": "Silvan Mosberger",
  "handle": "infinisil"
}

The maintainer is designated by a selector which must be one of:

handle (default): the maintainer's attribute name in lib.maintainers;
email, name, github, githubId, matrix, name: attributes of the maintainer's object, matched exactly; see maintainer-list.nix for the fields' definition.

`get-maintainer-pings-between.sh`

Gets which maintainers would be pinged between two Nixpkgs revisions. Outputs a JSON object on stdout mapping GitHub usernames to the attributes that they would be getting pinged for.

Example:

maintainers/scripts/get-maintainer-pings-between.sh HEAD^ HEAD

Conventions

`sha-to-sri.py`

sha-to-sri.py path ... (atomically) rewrites hash attributes (named hash or sha(1|256|512)) into the SRI format: hash = "{hash name}-{base64 encoded value}".

path must point to either a nix file, or a directory which will be automatically traversed.

sha-to-sri.py automatically skips files whose first non-empty line contains generated by or do not edit. Moreover, when walking a directory tree, the script will skip files whose name is yarn.nix or contains generated.
