This modifies the composer completion such that completing a room or user will insert an IMMUTABLE matrix.to LINK Entity for the range that was replaced. Display names will not have a colon after their name anymore as it seemed strange that we would insert one after a pill.
These have since been replaced by decorators that operator whether in MD mode or otherwise. This might not be optimal because LINK entities do not appear in MD mode at all at the moment, but instead you see the ()[] md notation version.
Any links in the composer that are recognised as matrix.to links will be decorated as `<span>`s with CSS classes (one of mx_UserPill or mx_RoomPill). This implementation has the nice bonus that switching to markdown (and back) will Just Work.
This will have some CSS changes coming to better match the design.
Hitting return in a code-block will now split the block into two code blocks. (Holding shift will still insert a soft newline into the current block).
We still need to make it a bit more obvious that consecutive code-blocks
are not contiguous - https://github.com/vector-im/riot-web/issues/4535
It turns out that the assertion made in
https://github.com/matrix-org/matrix-react-sdk/pull/1213 about `async`
functions returning bluebird promises was only correct when babel used an
inline version of the `asyncToGenerator` helper; in react-sdk we are using
`babel-transform-runtime` which means that we use a separate
`babel-runtime/helpers/asyncToGenerator`, which returns a native (or core-js)
Promise.
This meant that we were still in the situation where some methods returned
native Promises, and some bluebird ones, which is exactly the situation I
wanted to resolve by switching to bluebird in the first place: in short,
unless/until we get rid of all code which assumes Promises have a `done` method
etc, we need to make sure that everything returns a bluebird promise.
(Aside: there was debate over whether in the long term we should be trying to
wean ourselves off bluebird promises by assuming all promises are native. The
conclusion was that the complexity hit involved in doing so outweighed any
benefit of a potential future migration away from bluebird).
Use bluebird instead of the now removed "q" library.
Also, make sure we timeout and then `reflect` to effectively do an `allSettled` that waits for all promises to either be resolved or rejected. Then we filter for those that are fulfilled and return the completions.
The easiest way to stop the user from inserting whitespace onto the end of an entity is to toggle the entity state of the whitespace that was just entered. This allows the user to continue drafting a message without editing the link content.
This is for pasted `<a>` tags that have been copied from a website. We probably also want to be storing entities for substrings of content that are determined to be URLs.
