Parses an associative array from a string given the left bracket (default '['), right bracket (default ']'), key-value separator (default ':'), and element seprator (by default ',').

Parameters

s Source: the string to parse
lbracket dchar: the character that starts the associative array
rbracket dchar: the character that ends the associative array
keyval dchar: the character that associates the key with the value
comma dchar: the character that separates the elements of the associative array
doCount: the flag for deciding to report the number of consumed characters

Return Value

Type: auto

An associative array of type Target if doCount is set to No.doCount
A tuple containing an associative array of type Target and a size_t if doCount is set to Yes.doCount
