type t

State of the parser

val create : ?pos:Positions.pos -> Base.unit -> t

Create a new parser state. pos is the initial position, it defaults to {line=1;col=0;offset=0}.

val reset : ?pos:Positions.pos -> t -> Base.unit

Reset the given parsing state. The following always succeed:

reset t ?pos;
assert (t = create ?pos ())

val offset : t -> Base.int

Number of characters fed to the parser

val line : t -> Base.int

Position in the text

val column : t -> Base.int

val position : t -> Positions.pos

val stop : t -> Base.unit

Prevent the state from receiving any more characters. Trying to feed more characters will result in an exception, unless the state is reset.
