Tokens

The format strings that some configuration options accept can include tokens, which are replaced with a relevant value when they’re used. These are specified with a dollar sign followed by the name of the token. Like functions, tokens are case-sensitive; $author is not the same as $Author.

The available tokens for a given option are documented in the in-game configuration menu.

Error Tokens

The tokens $error and $errorID can be set in some format strings to display feedback to players. When set, the operation associated with the filter or predicate will be considered a failure. If errorID is used, it will be interpreted as a string ID, whereas error will be displayed as given.
