Preview HTTP and HTTPS URLs
Please, offer preview HTTP and HTTPS URLs in similar way WhatsApp and Telegram does. Make this an optional feature.
Therefore should it be an option which is off by default. Perhaps a small warning should be shown when it is enabled or near the setting of the option.
I'm neither using WhatsApp nor Telegram so I don't know what you mean. Can you either describe this in more detail or illustrate with a screenshot what you mean.
It would only apply to the first url with HTTP or HTTPS that is found in the message. If there is an error, display nothing.
Usually this is something that is being handled on the server side. Currently there is no XEP for this.

Yes, that is indeed helpful in finding the correct data to preview. However, a fallback is usually also implemented, by using the first image found in the page and Dublin Core is sometimes also used. See for example
<head profile="http://a9.com/-/spec/opensearch/1.1/" prefix="og: http://ogp.me/ns#">
...
<title>FOSDEM 2016 - Home</title>
<link rel="schema.DC" href="http://purl.org/DC/elements/1.0/" />
<meta name="DC.Title" content="Home"/>
<meta name="DC.Format" content="text/html" />

This will be very useful for spammers. "click here to buy some... http://..." and Conversation clicks for you.
Perhaps it should be configurable per account to have more control over it. Personally I never have spammers on my chats or conferences.
Hmm... In times of Stagefright when you only need an mp4 video to infect an Android device you probably don't want display any media by default.
What about your language, eh?
And yes, LaTeX is very helpful for scientific conversations.
And above all, why should LaTeX be stranger than HTML?
I, too, enjoy typing LaTeX on a mobile phone. No better way to spend the day than to type endless backslashes and all sorts of brackets with your thumb. While we're at it, why not add LaTeX autocomplete as well? In fact Conversations should also recognise if the content of a message is written in a certain programming language and colour code everything. Maybe add an option to auto-execute as well, as long as it's an expert option nothing's wrong.
What you are suggesting is pure feature creep, completely useless bloat that only a few ultra nerds will use to show off. I don't even think providing previews of HTTP URLs is necessary but at least it could maybe be of some use sometime for someone.
LaTeX works relatively well for writing documents. Don't shoehorn it into things it has nothing to do with.
I suggest LaTeX voters to open a separate issue. I vote for the opt-in preview feature with option: Off (default); Only in conversations with buddies in blist; In all conversations (dangerous, double check!).
Also I guess that showing image previews scaled down by Conversations may be considered quite safe (?). Though not quite sure.
Hi,
I have that feature in my SMS/MMS app (Textra) and I would gladly have it in Conversaionts app. If I send nor receive an url link, Textra read tag:
<meta property="og:description" content="">
and put it as website description and
<meta property="og:image" content="">
tag for image preview. It look really nice and its sometimes helpful because I know what is in url without opening it in a browser ;)
About privacy/security: This feature should be/or would be disabled for people who not receive our presence subscription, so if spammer send as link, then conversation would not display its preview :)

Privacy/Security: enable previews only for known contacts. Security: also possible to use Adblock or Mozilla URL reputational DBs, probably through a plugin. What do you think?
Firefox can be used as a webview so you'd gain any security features loaded there.
But how do you use that? Load the page in background and save a screeenshot?
URL preview just shows a few meaningful words and the 1st picture downsized. I don't see how FF can help here.
@ildar to get that you'll need to parse something, if that metadata is not in HEAD you'll fallback to what?
@ildar Did you use that and found it useful? Working? Not annoying?
Maybe I'm the only one where the preview disappears at random and the servers are contacted every time I hit back on or open the chat.
I'm not saying how good it's implemented in P-A-M. It is offtopic here, in Conversations tracker. Plz mention me at the corresponding issue at P-A-M I'm just pointing users to alternative(s) in this stagnated issue.
This is a good overview but given Conversations design decisions (E2EE as first-class feature) this leaves out server generated previews ("Approach 3").
Now whichever option you pick the preview display should be strictly limited to "trusted" contacts. The same logic that affects file autodownload can be reused.
If the preview was to be generated on the sender side then this additionally requires full-stanza encryption.
~~Blabber now allows server owners to host their own preview scripts 👍 https://codeberg.org/kriztan/blabber.im/commit/8287e3e39e9aac7de28aebb00b93459057289f0b~~ Wrong issue
@licaon-kter this is not correct. This is only the server rendered map preview and not a http preview. Http previews are generated in the app.
Given the current state of development of conversation.im (functional and excellent), I think this feature of OGP content preview is currently the most dearly missed feature when compared with all other IM clients we used previously (sms,facebook,steam)
In response to previous discussion
I believe it should be enabled by default but possible to turn off for the few who would turn it off
In a perfect world the OGP content request would be performed by the xmpp server or another trusted proxy, thus protecting the user's anonymity and hidden presence
There should be a manual fallback preview method if OGP is not supported by the URL
It should be possible for the person who sends the URL, to push preview data so that the recipient doesn't have to get it for themselves (imagine posting a link to a 100 user chat room, it would be wasteful for have every client in that chatroom hammer the server with requests when the original sender could have bundled the title and thumbnail automatically with his URL)
If a URL has a title and thumbnail, omit or trunkate the displaying the URL ?
