mod_http_oauth2: Allow user to decide which requested scopes to grant These should at the very least be shown to the user, so they can decide whether to grant them. Considered whether to filter the requested scopes down to actually understood scopes that would be granted, but decided that this was a bit complex for a first step, since role role selection and other kinds of scopes are mixed into the same field here.

# mod_tweet_data

This module adds [Open Graph Protocol](https://ogp.me) metadata to Twitter.com tweet URLs sent inside a MUC.

It's similar to [mod_ogp](https://modules.prosody.im/mod_ogp.html) but is adapted specifically to Twitter.com, which doesn't support the [Open Graph Protocol](https://ogp.me).

When a user sends a tweet URL in a MUC (where the message has its `id` equal to its `origin-id`), this module calls that URL to get the tweet data.
If it finds any, it sends a [XEP-0422 fastening](https://xmpp.org/extensions/xep-0422.html) applied to the original message that looks as follows (note, I haven't used real data here):

```xml
    <message xmlns="jabber:client" to="user@chat.example.org/resource" from="chatroom@muc.example.org" type="groupchat">
        <apply-to xmlns="urn:xmpp:fasten:0" id="82dbc94c-c18a-4e51-a0d5-9fd3a7bfd267">

Configuration
-------------

You'll need to provide a Twitter APIv2 bearer token.

```lua
Component "muc.example.org" "muc"
  modules_enabled = { "tweet_data" }
  twitter_apiv2_bearer_token  = { "some-very-long-string" }
```
