 ### Pleroma Settings Store
 Pleroma has mechanism that allows frontends to save blobs of json for each user on the backend. This can be used to save frontend-specific settings for a user that the backend does not need to know about.
 The parameter should have a form of `{frontend_name: {...}}`, with `frontend_name` identifying your type of client, e.g. `pleroma_fe`. It will overwrite everything under this property, but will not overwrite other frontend's settings.
 This information is returned in the `verify_credentials` endpoint.

 %%%               ejabberd configuration file
 %%%
 %%%'
 %%% The parameters used in this configuration file are explained in more detail
 %%% in the ejabberd Installation and Operation Guide.
 %%% Please consult the Guide in case of doubts, it is included with
 %%% your copy of ejabberd, and is also available online at
 %%% http://www.process-one.net/en/ejabberd/docs/
 %%% This configuration file contains Erlang terms.
 %%% In case you want to understand the syntax, here are the concepts:
 %%%
 %%%  - The character to comment a line is %
 %%%
 %%%  - Each term ends in a dot, for example:
 %%%      override_global.
 %%%
 %%%  - A tuple has a fixed definition, its elements are
 %%%    enclosed in {}, and separated with commas:
 %%%      {loglevel, 4}.
 %%%
 %%%  - A list can have as many elements as you want,
 %%%    and is enclosed in [], for example:
 %%%      [http_poll, web_admin, tls]
 %%%
 %%%    Pay attention that list elements are delimited with commas,
 %%%    but no comma is allowed after the last list element. This will
 %%%    give a syntax error unlike in more lenient languages (e.g. Python).
 %%%
 %%%  - A keyword of ejabberd is a word in lowercase.
 %%%    Strings are enclosed in "" and can contain spaces, dots, ...
 %%%      {language, "en"}.
 %%%      {ldap_rootdn, "dc=example,dc=com"}.
 %%%
 %%%  - This term includes a tuple, a keyword, a list, and two strings:
 %%%      {hosts, ["jabber.example.net", "im.example.com"]}.
 %%%
 %%%  - This config is preprocessed during release generation by a tool which
 %%%    interprets double curly braces as substitution markers, so avoid this
 %%%    syntax in this file (though it's valid Erlang).
 %%%
 %%%    So this is OK (though arguably looks quite ugly):
 %%%      { {s2s_addr, "example-host.net"}, {127,0,0,1} }.
 %%%
 %%%    And I can't give an example of what's not OK exactly because
 %%%    of this rule.
 %%%
 %%%.   =======================
 %%%'   OVERRIDE STORED OPTIONS
 %%
 %% Override the old values stored in the database.
 %%
 %%
 %% Override global options (shared by all ejabberd nodes in a cluster).
 %%
 %%override_global.
 %%
 %% Override local options (specific for this particular ejabberd node).
 %%
 %%override_local.
 %%
 %% Remove the Access Control Lists before new ones are added.
 %%
 %%override_acls.
 %%%.   =========
 %%%'   DEBUGGING
 %%
 %% loglevel: Verbosity of log files generated by ejabberd.
 %% 0: No ejabberd log at all (not recommended)
 %% 1: Critical
 %% 2: Error
 %% 3: Warning
 %% 4: Info
 %% 5: Debug
 %%
 {loglevel, 3}.
 %%%.   ================
 %%%'   SERVED HOSTNAMES
 %%
 %% hosts: Domains served by ejabberd.
 %% You can define one or several, for example:
 %% {hosts, ["example.net", "example.com", "example.org"]}.
 %%
 {hosts, ["pleroma.soykaf.com"] }.
 %%
 %% route_subdomains: Delegate subdomains to other XMPP servers.
 %% For example, if this ejabberd serves example.org and you want
 %% to allow communication with an XMPP server called im.example.org.
 %%
 %%{route_subdomains, s2s}.

 defmodule Pleroma.Plugs.RateLimiter do
  @moduledoc """
  ## Configuration
  A keyword list of rate limiters where a key is a limiter name and value is the limiter configuration. The basic configuration is a tuple where:
  * The first element: `scale` (Integer). The time scale in milliseconds.
  * The second element: `limit` (Integer). How many requests to limit in the time scale provided.
  It is also possible to have different limits for unauthenticated and authenticated users: the keyword value must be a list of two tuples where the first one is a config for unauthenticated users and the second one is for authenticated.
  To disable a limiter set its value to `nil`.
  ### Example
      config :pleroma, :rate_limit,
        one: {1000, 10},
        two: [{10_000, 10}, {10_000, 50}],
        foobar: nil
  Here we have three limiters:
  * `one` which is not over 10req/1s
  * `two` which has two limits: 10req/10s for unauthenticated users and 50req/10s for authenticated users
  * `foobar` which is disabled
  ## Usage
  Inside a controller:
      plug(Pleroma.Plugs.RateLimiter, :one when action == :one)
      plug(Pleroma.Plugs.RateLimiter, :two when action in [:two, :three])
  or inside a router pipiline:
      pipeline :api do
        ...
        plug(Pleroma.Plugs.RateLimiter, :one)
        ...
