* This file must be valid JSON. But comments are allowed
*
* Please edit settings.json, not settings.json.template
*
* Please note that starting from Etherpad 1.6.0 you can store DB credentials in
* a separate file (credentials.json).
*
*
* ENVIRONMENT VARIABLE SUBSTITUTION
* =================================
*
* All the configuration values can be read from environment variables using the
* syntax "${ENV_VAR}" or "${ENV_VAR:default_value}".
*
* This is useful, for example, when running in a Docker container.
*
* DETAILED RULES:
* - If the environment variable is set to the string "true" or "false", the
* value becomes Boolean true or false.
* - If the environment variable is set to the string "null", the value
* becomes null.
* - If the environment variable is set to the string "undefined", the setting
* is removed entirely, except when used as the member of an array in which
* case it becomes null.
* - If the environment variable is set to a string representation of a finite
* number, the string is converted to that number.
* - If the environment variable is set to any other string, including the
* empty string, the value is that string.
* - If the environment variable is unset and a default value is provided, the
* value is as if the environment variable was set to the provided default:
* - "${UNSET_VAR:}" becomes the empty string.
* - "${UNSET_VAR:foo}" becomes the string "foo".
* - "${UNSET_VAR:true}" and "${UNSET_VAR:false}" become true and false.
* - "${UNSET_VAR:null}" becomes null.
* - "${UNSET_VAR:undefined}" causes the setting to be removed (or be set
* to null, if used as a member of an array).
* - If the environment variable is unset and no default value is provided,
* the value becomes null. THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF
* ETHERPAD; if you want the default value to be null, you should explicitly
* specify "null" as the default value.
*
* EXAMPLE:
* "port": "${PORT:9001}"
* "minify": "${MINIFY}"
* "skinName": "${SKIN_NAME:colibris}"
*
* Would read the configuration values for those items from the environment
* variables PORT, MINIFY and SKIN_NAME.
*
* If PORT and SKIN_NAME variables were not defined, the default values 9001 and
* "colibris" would be used.
* The configuration value "minify", on the other hand, does not have a
* designated default value. Thus, if the environment variable MINIFY were
* undefined, "minify" would be null.
*
* REMARKS:
* 1) please note that variable substitution always needs to be quoted.
*
* "port": 9001, <-- Literal values. When not using
* "minify": false substitution, only strings must be
* "skinName": "colibris" quoted. Booleans and numbers must not.
*
* "port": "${PORT:9001}" <-- CORRECT: if you want to use a variable
* "minify": "${MINIFY:true}" substitution, put quotes around its name,
* "skinName": "${SKIN_NAME}" even if the required value is a number or
* a boolean.
* Etherpad will take care of rewriting it
* to the proper type if necessary.
*
* "port": ${PORT:9001} <-- ERROR: this is not valid json. Quotes
* "minify": ${MINIFY} around variable names are missing.
* "skinName": ${SKIN_NAME}
*
* 2) Beware of undefined variables and default values: nulls and empty strings
* are different!
*
* This is particularly important for user's passwords (see the relevant
* section):
*
* "password": "${PASSW}" // if PASSW is not defined would result in password === null
* "password": "${PASSW:}" // if PASSW is not defined would result in password === ''
*
* If you want to use an empty value (null) as default value for a variable,
* simply do not set it, without putting any colons: "${SOFFICE}".
*
* 3) if you want to use newlines in the default value of a string parameter,
* use "\n" as usual.
