# Clients requesting push notifications can either have the body of
# the message sent in the notification poke along with other details
# like the sender, or just the event ID and room ID (`event_id_only`).
# If clients choose the former, this option controls whether the
# notification request includes the content of the event (other details
# like the sender are still included). For `event_id_only` push, it
# has no effect.
#
# For modern android devices the notification content will still appear
# because it is loaded by the app. iPhone, however will send a
# notification saying only that a message arrived and who it came from.

# User Directory configuration
#
# 'enabled' defines whether users can search the user directory. If
# false then empty responses are returned to all queries. Defaults to
# true.
#
# 'search_all_users' defines whether to search all users visible to your HS
# when searching the user directory, rather than limiting to users visible
# in public rooms.  Defaults to false.  If you set it True, you'll have to run
# UPDATE user_directory_stream_pos SET stream_id = NULL;
# on your database to tell it to rebuild the user_directory search indexes.
#
#user_directory:
#  enabled: true

# User Consent configuration
#
# for detailed instructions, see
# https://github.com/matrix-org/synapse/blob/master/docs/consent_tracking.md
#
# Parts of this section are required if enabling the 'consent' resource under
# 'listeners', in particular 'template_dir' and 'version'.
#
# 'template_dir' gives the location of the templates for the HTML forms.
# This directory should contain one subdirectory per language (eg, 'en', 'fr'),
# and each language directory should contain the policy document (named as
# '<version>.html') and a success page (success.html).
#
# 'version' specifies the 'current' version of the policy document. It defines
# the version to be served by the consent resource if there is no 'v'
# parameter.
#
# 'server_notice_content', if enabled, will send a user a "Server Notice"
# asking them to consent to the privacy policy. The 'server_notices' section
# must also be configured for this to work. Notices will *not* be sent to
# guest users unless 'send_server_notice_to_guests' is set to true.
#
# 'block_events_error', if set, will block any attempts to send events
# until the user consents to the privacy policy. The value of the setting is
# used as the text of the error.
#
# 'require_at_registration', if enabled, will add a step to the registration
# process, similar to how captcha works. Users will be required to accept the
# policy before their account is created.
#
# 'policy_name' is the display name of the policy users will see when registering
# for an account. Has no effect unless `require_at_registration` is enabled.
# Defaults to "Privacy Policy".
#
#user_consent:
#  template_dir: res/templates/privacy
#  version: 1.0
#  server_notice_content:
#    msgtype: m.text
#    body: >-

# Local statistics collection. Used in populating the room directory.
#
# 'bucket_size' controls how large each statistics timeslice is. It can
# be defined in a human readable short form -- e.g. "1d", "1y".
#
# 'retention' controls how long historical statistics will be kept for.
# It can be defined in a human readable short form -- e.g. "1d", "1y".

# Server Notices room configuration
#
# Uncomment this section to enable a room which can be used to send notices
# from the server to users. It is a special room which cannot be left; notices
# come from a special "notices" user id.
#
# If you uncomment this section, you *must* define the system_mxid_localpart
# setting, which defines the id of the user which will be used to send the
# notices.
#
# It's also possible to override the room name, the display name of the
# "notices" user, and the avatar for the user.
#
#server_notices:
#  system_mxid_localpart: notices
#  system_mxid_display_name: "Server Notices"
#  system_mxid_avatar_url: "mxc://server.com/oumMVlgDnLYFaPVkExemNVVZ"
#  room_name: "Server Notices"



# Uncomment to disable searching the public room list. When disabled
# blocks searching local and remote room lists for local and remote
# users by always returning an empty list for all queries.
#
#enable_room_list_search: false

# The `alias_creation` option controls who's allowed to create aliases
# on this server.
#
# The format of this option is a list of rules that contain globs that
# match against user_id, room_id and the new alias (fully qualified with
# server name). The action in the first rule that matches is taken,
# which can currently either be "allow" or "deny".
#
# Missing user_id/room_id/alias fields default to "*".
#
# If no rules match the request is denied. An empty list means no one
# can create aliases.
#
# Options for the rules include:
#
#   user_id: Matches against the creator of the alias
#   alias: Matches against the alias being created
#   room_id: Matches against the room ID the alias is being pointed at
#   action: Whether to "allow" or "deny" the request if the rule matches
#
# The default is:
#
#alias_creation_rules:
#  - user_id: "*"
#    alias: "*"
#    room_id: "*"
#    action: allow

# The `room_list_publication_rules` option controls who can publish and
# which rooms can be published in the public room list.
#
# The format of this option is the same as that for
# `alias_creation_rules`.
#
# If the room has one or more aliases associated with it, only one of
# the aliases needs to match the alias rule. If there are no aliases
# then only rules with `alias: *` match.
#
# If no rules match the request is denied. An empty list means no one
# can publish rooms.
#
# Options for the rules include:
#
#   user_id: Matches agaisnt the creator of the alias
#   room_id: Matches against the room ID being published
#   alias: Matches against any current local or canonical aliases
#            associated with the room
#   action: Whether to "allow" or "deny" the request if the rule matches
#
# The default is:
#
#room_list_publication_rules:
#  - user_id: "*"
#    alias: "*"
#    room_id: "*"
#    action: allow
