The function internal_prep_message is kind of awkward to
call, so I'm moving most of its implementation to
_internal_prep_message() for upcoming refactorings.
We used to have code scattered in multiple places to
calculate things like admin options, preview urls,
subscriber counts, and rendered descriptions for
streams before we rendered templates in the "Manage
Stream" code.
These are all consolidated into a new function
called stream_data.update_calculated_fields().
This is mostly code cleanup, but it also fixes a bug where
the "View Stream" button would not work for a newly created
stream.
This doesn't quite complete the goals of #4650, which has a plan for
how to remove this entirely, but it causes this problematic code to
now be contained to a very rare case.
Refactored significantly by tabbott just due to rebase age.
Fixes#3629.
Modified composebox_typeahead.js to recognize the triple backtick
and tilde for code blocks, and added appropriate typeahead functions
in that file and in typeahead_helper.js.
Additionally, a new file pygments_data.js contains a dictionary of
the supported languages, mapping to relative popularity
rankings. These rankings determine the order of sort of the
languages in the typeahead.
This JavaScript file is actually in static/generated/pygments_data.js, as it
is generated by a Python script, tools/build_pymgents_data.py. This is
so that if Pygments adds support for new languages, the JavaScript file
will be updated appropriately. This python script uses a set of popularity
rankings defined in lang.json.
Corresponding unit tests were also added.
Fixes#4111.
The function check_stream_existence() temporarliy got moved
to stream_create.js, and our call from compose.js was still trying
to find it in subs.js. Now we move the function to compose.js,
since we no longer use it stream_create.js.
This function is pretty dubious, and we may want to only check
for duplicate stream names locally.
When the user creates a stream, we no longer do a synchronous
check on the back end to find if the stream name already exists.
Instead, we only check our local data, which will prevent many
typical errors, and then we let the back end capture duplicates for
stream names that the client doesn't know about.
We also tone down errors when the stream name is blank--we
only whine about empty streams right before submitting the form.
Also, since our check for duplicate streams is less expensive,
we now capture the "input" event instead of the "focusout" event,
so that if you fix up the name to avoid a collision, you get more
immediate feedback.
When we do detect stream name errors, we conveniently focus the
text field to let the user correct the problem.
It's technically the number of users yesterday. Also, "number of active
users today" suggests something like daily actives today, whereas this graph
currently shows 2-week actives.
