This restyles the message_controls options to center them horizontally
while fixing them closer to the right side of the edge, along with just
replacing the edit button with a preview source button once editing is
disabled.
This moves the edit button to underneath the timestamp such that when
you hover over a message now the timestamp hides itself and the edit
button appears (if editing is allowed).
Fixes#1733 and other annoying issues with this field.
* Fixes handling of multiple stream links and invalid stream names.
* Fixes text regex so it handle hash sign the right way.
* Adds tests for these stream link cases.
Changes editibility type from NONE to FULL, and makes Save and Cancel
buttons work. Exposes a new bug, which is that changing the topic changes
the topic for the recipient row, rather than the message. See #2278.
The widget that gets built in topic_list.build_widget()
now knows how to add itself to its parent element and expose
an interface to retrieve the parent.
For cases where we are zoomed in to a stream and then go
to a different narrow (Home, PMs, etc.), we now let
topic_list.zoom_out orchestrate the removal of the topic list
instead of stream_list.zoom_out.
This will help us when we move to a world where topic_list
redraws topic lists on zoom-in/zoom-out, because we won't
waste effort rebuilding lists that are about to be removed.
The flow for topic list zooming is kind of complicated now, but
it's mostly a consequence of the way the UI works.
* stream_list tells topic_list to set up the topic list
click handlers to have callbacks to stream_list
* topic_list click handlers call to stream_list zoom methods
to hide/show all the other streams
* stream_list zoom methods call back to topic_list methods to
redraw topics as needed (this isn't happening yet, but allowing
topic_list.js to know that it's zoomed will set the stage for
this to happen in a more controlled manner)
We no longer use active_stream_name(), which was mostly a
duplicate of narrow.stream(). For nonsensical queries like
"stream:foo stream:bar" the behavior may change slightly here.
We know that we don't handle non-sensical queries particularly
well, but at least if we always go through narrow.stream(),
the behavior will be consistent.
I did test this with some sensible compound narrows, like searching
for a keyword within a stream.
After adding the ability to add stream links to messages using
the following pattern '#**stream_name**' there was a problem
with rendering this using our markdown engine because '**' means
bold text so that would render just to bold text.
To solve this I had to add regular expression in marked.js to match
that pattern and when it matches I call handleStreamLinks in echo.js
which will correctly render it to HTML.
Fixes#2218.
[tweaked by tabbott to url-encode the stream name in the URL and
adding the missing "#" in the display].
