`Mastodon`_ is an ostatus based twitter-like federated social 
network node. It has an API that allows you to interact with its 
every aspect. This is a simple python wrapper for that api, provided
as a single python module. By default, it talks to the 
`Mastodon flagship instance`_, but it can be set to talk to any 
node running Mastodon.

A note about rate limits
------------------------
Mastodons API rate limits per IP. By default, the limit is 150 requests per 5 minute 
time slow. This can differ from instance to instance and is subject to change.
Mastodon.py has three modes for dealing with rate limiting that you can pass to 
the constructor, "throw", "wait" and "pace", "wait" being the default.

In "throw" mode, Mastodon.py makes no attempt to stick to rate limits. When
a request hits the rate limit, it simply throws a MastodonRateLimitError. This is
for applications that need to handle all rate limiting themselves (i.e. interactive apps), 
or applications wanting to use Mastodon.py in a multi-threaded context ("wait" and "pace" 
modes are not thread safe).

In "wait" mode, once a request hits the rate limit, Mastodon.py will wait until
the rate limit resets and then try again, until the request succeeds or an error
is encountered. This mode is for applications that would rather just not worry about rate limits
much, don't poll the api all that often, and are okay with a call sometimes just taking
a while.

In "pace" mode, Mastodon.py will delay each new request after the first one such that, 
if requests were to continue at the same rate, only a certain fraction (set in the
constructor as ratelimit_pacefactor) of the rate limit will be used up. The fraction can
be (and by default, is) greater than one. If the rate limit is hit, "pace" behaves like
"wait". This mode is probably the most advanced one and allows you to just poll in
a loop without ever sleeping at all yourself. It is for applications that would rather
just pretend there is no such thing as a rate limit and are fine with sometimes not
being very interactive.

A note about IDs
----------------
Mastodons API uses IDs in several places: User IDs, Toot IDs, ...

While debugging, it might be tempting to copy-paste in IDs from the
web interface into your code. This will not work, as the IDs on the web
interface and in the URLs are not the same as the IDs used internally
in the API, so don't do that.

Return values
-------------
Unless otherwise specified, all data is returned as python 
dictionaries, matching the JSON format used by the API.

    }

App registration and user authentication
----------------------------------------
Before you can use the mastodon API, you have to register your 
application (which gets you a client key and client secret) 
and then log in (which gets you an access token). These functions 
allow you to do those things.
For convenience, once you have a client id, secret and access token, 
you can simply pass them to the constructor of the class, too!

Note that while it is perfectly reasonable to log back in whenever 
your app starts, registering a new application on every 
startup is not, so don't do that - instead, register an application 
once, and then persist your client id and secret. Convenience
methods for this are provided.
