Method Details

tokenize

public static reactor.util.function.Tuple2<FlagSet,List<String>> tokenize(String flagPrefix, String input)

Splits the input into tokens. A token is delimited by double quotes or by whitespaces if there are none. A whitespace character can be escaped using a backslash to indicate that it should not delimit a token, and a double quote can be escaped the same way to indicate that it is intended to be a litteral character and not a token delimiter. Once tokens are extracted, they are separated into flags and arguments. A token starting with "--" followed by at least 1 character is treated as a flag, the rest are arguments.

Parameters:

flagPrefix - the prefix used to introduce command flags

input - the input to tokenize

Returns:

a Tuple2 which first value is a FlagSet that contains the tokens that are flags, and second value is a List containing the tokens that are arguments
