Syntax
string_expression ::= 'string:' string_expression_item string_expression_item ::= ( plain_string | [ varsub ] )* varsub ::= ( '$' Path ) | ( '${' Path '}' ) plain_string ::= ( '$$' | non_dollar )* non_dollar ::= any character except '$'
Description
String expressions interpret the expression string as text. If no expression string is supplied the resulting string is empty. The string can contain variable substitutions of the form $name or ${path}, where name is a variable name, and path is a path expression. The escaped string value of the path expression is inserted into the string. To prevent a $ from being interpreted this way, it must be escaped as $$.
