We also remove some unreachable code. Calling
split() always returns at least one token, even
if it's just the empty string. This is tested
directly on this commit, plus messages with
empty content get rejected pretty early in
the execution path.
The "/stats" command doesn't actually do anything
interesting yet, and it also writes to the message
feed instead of replying directly to the user.
The history of this command was that it was
written during a PyCon sprint. It was mainly intended
as an example for subsequent slash commands. The
ones we built after "/stats" have sort of outgrown
"/stats" and don't follow the original structure
for "/stats". (The "/day", "/ping", and "/settings"
commands were built shortly after.)j
We probably want to ressurect "/stats" fairly soon,
after figuring out some useful stats and refining
the UI.
As you can see from this commit, resurrecting the
code here shouldn't be too difficult, but it
may actually be pretty rare that we just translate
slash commands into fleshed out messages.
These two slash commands now use zcommand to talk to
the server, so we have no Message overhead, and if you're
on a stream, you no longer spam people by accident.
The commands now also give reasonable messages
if you are already in the mode you ask for.
It should be noted that by moving these commands out of
widget.py, they are no longer behind the ALLOW_SUB_MESSAGES
setting guard.
API users, particularly bots, can now send a field
called "widget_content" that will be turned into
a submessage for the web app to look at. (Other
clients can still rely on "content" to be there,
although it's up to the bot author to make the
experience good for those clients as well.)
Right now widget_content will be a JSON string that
encodes a "zform" widget with "choices." Our first
example will be a trivia bot, where users will see
something like this:
Which fruit is orange in color?
[A] orange
[B] blackberry
[C] strawberry
The letters will be turned into buttons on the webapp
and have canned replies.
This commit has a few parts:
- receive widget_content in the request (simply
validating that it's a string)
- parse the JSON in check_message and deeply
validate its structure
- turn it into a submessage in widget.py
The only slash command implemented in this initial
version is an extremely crippled version of a
"/stats" slash command that reports that you are
running 1 server.
