NIP-34

git stuff

draft optional

This NIP defines all the ways code collaboration using and adjacent to git can be done using Nostr.

Repository announcements

Git repositories are hosted in Git-enabled servers, but their existence can be announced using Nostr events, as well as their willingness to receive patches, bug reports and comments in general.

{
  "kind": 30617,
  "content": "",
  "tags": [
    ["d", "<repo-id>"],
    ["name", "<human-readable project name>"],
    ["description", "brief human-readable project description>"],
    ["web", "<url for browsing>", ...], // a webpage url, if the git server being used provides such a thing
    ["clone", "<url for git-cloning>", ...], // a url to be given to `git clone` so anyone can clone it
    ["relays", "<relay-url>", ...] // relays that this repository will monitor for patches and issues
  ]
}

The tags web, clone, relays can have multiple values.

Except d, all tags are optional.

Patches

Patches can be sent by anyone to any repository. Patches to a specific repository SHOULD be sent to the relays specified in that repository's announcement event's "relays" tag. Patch events SHOULD include an a tag pointing to that repository's announcement address.

{
  "kind": 1617,
  "content": "<patch>", // contents of <git format-patch>
  "tags": [
    ["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>"],
    ["p", "<repository-owner>"],
    ["p", "<other-user>"], // optionally send the patch to another user to bring it to their attention

    // for the first patch in a thread or series
    ["t", "root"],

    // optional tags for when it is desirable that the merged patch has a stable commit id
    // these fields are necessary for ensuring that the commit resulting from applying a patch
    // has the same id as it had in the proposer's machine -- all these tags can be omitted
    // if the maintainer doesn't care about these things
    ["commit", "<current-commit-id>"],
    ["parent-commit", "<parent-commit-id>"],
    ["commit-pgp-sig", "-----BEGIN PGP SIGNATURE-----..."], // empty string for unsigned commit
    ["committer", "<name>", "<email>", "<timestamp>", "<timezone offset in minutes>"],
  ]
}

Issues

Issues are Markdown text that is just human-readable conversational threads related to the repository: bug reports, feature requests, questions or comments of any kind. Like patches, these SHOULD be sent to the relays specified in that repository's announcement event's "relays" tag.

{
  "kind": 1621,
  "content": "<markdown text>",
  "tags": [
    ["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>"],
    ["p", "<repository-owner>"]
  ]
}

Replies

Replies are also Markdown text. The difference is that they MUST be issued as replies to either a kind:1621 issue or a kind:1617 patch event. The threading of replies and patches should follow NIP-10 rules.

{
  "kind": 1622,
  "content": "<markdown text>",
  "tags": [
    ["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>", "<relay-url>"],
    ["e", "<issue-or-patch-id-hex>", "", "root"],

    // other "e" and "p" tags should be applied here when necessary, following the threading rules of NIP-10
    ["p", "<patch-author-pubkey-hex>", "", "mention"],
    ["e", "<previous-reply-id-hex>", "", "reply"],
    // ...
  ]
}

Possible things to be added later

• "status" kind (for letting people know a patch was merged or an issue was fixed or won't be fixed)
• "branch merge" kind (specifying a URL from where to fetch the branch to be merged)
• "cover letter" kind (to which multiple patches can refer and serve as a unifying layer to them)
• inline file comments kind (we probably need one for patches and a different one for merged files)
