discourse/config/site_settings.yml

# Available options:
#
# default            - The default value of the setting.
# client             - Set to true if the javascript should have access to this setting's value.
# refresh            - Set to true if clients should refresh when the setting is changed.
# min                - For a string setting, the minimum length. For an integer setting, the minimum value.
# max                - For a string setting, the maximum length. For an integer setting, the maximum value.
# regex              - A regex that the value must match.
# validator          - The name of the class that will be use to validate the value of the setting.
# allow_any          - For choice settings allow items not specified in the choice list (default true)
# secret             - Set to true if input type should be password and value needs to be scrubbed from logs (default false).
# enum               - The setting has a fixed set of allowed values, and only one can be chosen.
#                      Set to the class name that defines the set.
# shadowed_by_global - "Shadow" a site setting with a GlobalSetting. If the GlobalSetting
#                      exists it will be used instead of the setting and the setting will be hidden.
#                      Useful for things like API keys on multisite.
# locale_default     - A hash which overrides according to `SiteSetting.default_locale`.
#                      The key should be as the same as possible value of default_locale.
#
#
# type: email    - Must be a valid email address.
# type: username - Must match the username of an existing user.
# type: list     - A list of values, chosen from a set of valid values defined in the choices option.
# type: enum     - A single value, chosen from a set of valid values in the choices option.
#
# A type:list setting with the word 'colors' in its name will make color values have a bold line of the corresponding color
