Description copied from class: LexerSource

Match marker against input consumering lexer source as it goes...Unless it does not match then it reverts lexer source back to point when this method was invoked.

Specified by:

indent - eat any leading whitespace

withNewline - includes a check that marker is followed by newline or EOF

Returns:

true if marker matches...false otherwise

Throws:
