By using `display: flex` and `flex-direction: column-reverse`, the chat
now automatically scrolls down when loaded, without requiring any
extra JavaScript.
We still need to scroll down with JavaScript when sending a message.
By using `column-reverse`, the messages container now works in reverse.
So the newest message is the first element in the container and the
oldest message is the last. This is the reverse of before.
Due to this, this change will likely break some plugins.
* Checkmark and edit modal button are now on the right
* Instead of showing checkmarks for MUC messages,
we now show them as light grey before MUC reflection
* Simplify message markup by requiring less `if` statements
- new config option `singleton`.
- new plugin `converse-uniview`
- removed `converse-embedded`.
- various CSS changes, to properly render an embedded full app
- don't re-open cached and non-autojoined chats in singleton mode
The goal here is to extend the `embedded` `view_mode` so that the full app can
also be embedded, not just a single MUC or private chat.
To do this, we'll need to differentiate between multi and singleton chat apps.
* A singleton chat app contains only a single chat.
* A multi-chat app can contain zero or more chats
So we introduce a new config option, `singleton`, which when used with
`view_mode` set to `embedded` will determine whether a single chat or the full
app is embedded.
Similarly, in `overlayed`, `fullscreen` and `mobile` view modes, `singleton`
set to true will allow only one chat within the parameters of that view mode.
We're appropriating the word `singleton` and introducing the concepts of
`uniview` and `multiview` (see a785ca8) to cover what was
previously meant with `singleton`.
updates #1297
That way we don't lose the user's input values, we avoid flashing and we
avoid unnecessary rendering.
In the process, fixed an annoying issue where Chrome auto-completes
what it thinks is the username into the "Language Tag" field of the MUC
config form.
Instead we tell Chrome that the MUC JID is the username, thereby also
letting it save the password to to that JID.
