Macro gstuff::take_until_find_parse_s

macro_rules! take_until_find_parse_s {
    ($i: expr, $starts: expr, $remainder: ident! ($($args:tt)*)) => { ... };
    ($i: expr, $starts: expr, $f: expr) => { ... };
}

$starts is an optional Pattern used to optimize the $remainder search.

For example, with jetscii: take_until_find_parse_s! ("foo bar", ascii_chars! ('b'), tag_s! ("bar")).
