# A bit opinionated titlefetching
|
|
|
|
## Preparation
|
|
|
|
```
|
|
load Web
|
|
config plugins.web.snarfMultipleUrls True
|
|
config plugins.web.snarferShowDomain False
|
|
config plugins.web.snarferShowTargetDomain False
|
|
config supybot.protocols.http.userAgents "Limnoria UrlPreviewBot"
|
|
config supybot.protocols.http.peekSize 1048576
|
|
```
|
|
|
|
- enables the plugin (shipped with Limnoria)
|
|
- enables titlefetching for all links on line, not just the first one
|
|
- disables showing domain (small protection against multiple titlesfetcherrs
|
|
entering a loop or simply not annoying users with clientside link previews
|
|
(Matrix/Telegram bridges/relays included))
|
|
- disables showing redirect target (see previous point)
|
|
- sets user-agent to "Limnoria UrlPreviewBot" instead of ['Mozilla/5.0 (compatible; utils.web python module)' from 2005](https://github.com/ProgVal/Limnoria/blame/2990fcd302afdc6a3b741594017c3959fd5da2fd/src/utils/web.py#L120)
|
|
- I have heard that it's bad to pretend to be something you aren't and
|
|
Twitter will only give you HTML `<title>`s if your user-agent contains
|
|
`UrlPreviewBot`, [thanks Tulir's Synapse patch](https://mau.dev/maunium/synapse/-/commit/55d926999cffee893cb4951890a33985beaf70ba)
|
|
- search for HTML titles from the first MEGABYTE of the webpage as modern
|
|
web is horrible (looking at you [HS](https://hs.fi) & [YouTube](https://youtube.com))
|
|
|
|
## Actually enabling it
|
|
|
|
```
|
|
config channel #CHAN plugins.web.titleSnarfer True
|
|
```
|
|
|
|
- enables titlefetching per-channel, on #CHAN to be accurate
|
|
(avoiding unwanted channels in case of botloop)
|
|
- `"channel #CHAN"` could also be replaced with `network NETWORKNAME` for
|
|
every channel on network or `config` (or omitted entirely) for
|
|
everywhere (channel takes priority over network which _probably_ takes
|
|
priority over global)
|
|
|
|
## Excluding domains from titlefetching
|
|
|
|
```
|
|
config supybot.plugins.Web.nonSnarfingRegexp m/(t.me|matrix.to|facebook.com|instagram.com|imgur.com)/
|
|
```
|
|
|
|
- regexp to block the listed domains, which are the first useless
|
|
examples I have encountered recently. I just stole the regexp from
|
|
[canonical Limnoria](https://github.com/ProgVal/Limnoria/wiki/Canonical-%23limnoria-doc)
|
|
|
|
## Titlesnarfing ignored users
|
|
|
|
While I personally don't like to do this, it's possible by
|
|
|
|
```
|
|
config channel #CHAN plugins.web.checkignored False
|
|
```
|
|
|
|
I may have the bot on multiple sides of relay or the user may be ignored due
|
|
to abuse so this may result into spam.
|
|
|
|
## Bonus: Fediverse
|
|
|
|
If [the Fediverse plugin is configured with secure fetch](https://github.com/progval/Limnoria/tree/master/plugins/Fediverse),
|
|
fetching Fediverse profiles/statuses/usernames can be enabled by:
|
|
|
|
```
|
|
channel #CHAN plugins.Fediverse.snarfers.profile true
|
|
channel #CHAN plugins.Fediverse.snarfers.status true
|
|
channel #CHAN plugins.Fediverse.snarfers.username true
|
|
```
