Value Details
abstract val lexical : Tokens
lexical is the component responsible for consuming some basic kind of input (usually character-based) and turning it into the tokens understood by these parsers.
Method Details
def phrase[t](p : Parser[t]) : Parser[t]

A parser generator delimiting whole phrases (i.e. programs).

phrase(p) succeeds if p succeeds and no input is left over after p.

Parameters
p - the parser that must consume all input for the resulting parser to succeed.
Returns
a parser that has the same result as `p', but that only succeeds if p consumed all the input.
