mod_http_muc_log: Remove dead code This might be something left over since a different variant where the loop went like `for n = i-1, i-100, -1 do ... end` i.e. it went trough a fixed number of items instead of all the page until the current message. Then it would have needed something to stop going over the end, but since the checks are simple it shouldn't be much of a problem looping over even a very busy day.

# 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" }
```
