Nostr Simple Publish

Very simple and opinionated module to publish content to the Nostr network.
More info about Nostr: https://github.com/nostr-protocol/nostr

In case you missed it, when the founder of Drupal Dries Buytaert discovered Nostr it was love on first sight.

Currently only works for a single Drupal user.

Requirements

• PHP 8.1+ and the GMP extension - https://www.php.net/manual/en/ref.gmp.php

How it works

Adds a 'Publish to Nostr' fieldset to node forms, protected by the
'publish to nostr network' permission. It currently assumes the content of
your post is stored in the 'body' field, but this can be overridden by a
setting.

Once the node has been sent, you can't publish it anymore. The event id is
stored in the nostr_simple_publish table.

There's an extra permission to view debug information after trying to post to
the network.

Configuration

Posts to the network need to be signed, so we need the public and private key
of your Nostr account and one relay.

// Path to Nostr public and private key files.
// Put these files somewhere outside your webroot!
// The values of the keys are the hex encoded versions, not bech32 (which
// either start with npub or nsec).
// Use https://damus.io/key/ or https://github.com/rot13maxi/key-convertr
// to convert.
$settings['nostr_public_key_file'] = '/path/to/public-key-file';
$settings['nostr_private_key_file'] = '/path/to/private-key-file';

// Nostr relay - find other relays at https://nostr.watch/relays/find.
// This relay seems to work fine. In case you are not connected with this one,
// add it to your relays so posts show up in your client as well.
$settings['nostr_relay'] = 'wss://nostr.pleb.network';

```
// Content fields - defaults to 'body'.
$settings['nostr_content_fields'] = ['field_description'];
```

Roadmap

Generally, it's not the purpose of this module to become a relay or a fully
featured nostr client, hence the name.
