For error messages we still use the `message` attribute, since error
messages generally don't have a body, and if one does, it likely refers
to the `body` of a rejected message that the error refers to.
We're still setting both `body` and `message` attributes, but usage of
`message` for a normal `chat`, `groupchat` or `headline` stanza should
be considered deprecated.
Trigger an `emojiSelected` event instead of manually calling `insertIntoTextArea` on the `converse-message-form` a component.
This loosens the coupling between the emoji picker and `converse-message-form`.
Call `disableArrowNavigation` when the emoji-picker is disconnected from
the DOM or when escape is pressed. See #2754
inside `parseMessageForMUCCommands`.
If the function doesn't find any core MUC commands, it calls
`parseMessageForCommands` which will trigger the hook.
I think it's appropriate to give built-in commands preference above
commands by 3rd party plugins and this also solves the issue of the hook
being triggered twice (once in `parseMessageForMUCCommands` and
then again in `parseMessageForCommands`).
And use that to render images in unfurls.
This solves the issue of github URL unfurl images not having an image
extension and then being rendered as a hyperlink by `converse-rich-text`.
Instead, we know that it's supposed to be a url, so we just use `converse-image`.
This allows for more flexibility in configuring which media URLs will
automatically render and which media URLs may be manually rendered by
the user (via the message actions dropdown).
For example, suppose you want to automatically render all media URLs
from https://xmpp.org, but still allow other media (which won't render
by default) to be rendered manually by the user (by clicking the "Show
URL previews" message dropdown action).
In this case, you set `render_media` to `['xmpp.org']` and
`allowed_image_domains` to `null` or `undefined`.
Or if you want to automatically render images from xmpp.org, and
restrict the domains users might manually click to render, you can add
those extra domains to `allowed_image_domains`.
It's now necessary to add a `converse-root` element in the DOM where you
want Converse to render (previously it was any element with the id
`#conversejs`).
Also, turned `converse-chats` element into a Lit element and re-render
`converse-root` and `converse-chats` when the `view-mode` or `singleton`
settings change. This is a step towards being able to change the view
mode on the fly and have the entire chat re-render appropriately.
