Module `Gramlib.LStream`Source

Extending streams with a (non-canonical) location function

Sourcetype 'a t

Sourceval from : ?loc:Loc.t -> (unit -> ('a * Loc.t) option) -> 'a t

Sourceval current_loc : 'a t -> Loc.t

Returning the loc of the last consumed element or the initial loc if no element is consumed

Sourceval max_peek_loc : 'a t -> Loc.t

Returning the loc of the max visited element or the initial loc if no element is consumed

Sourceval interval_loc : int -> int -> 'a t -> Loc.t

Returning the loc starting after element bp (counting from 0) and spanning up to already peeked element at position ep, under the assumption that bp <= ep; returns an empty interval if bp = ep; returns the empty initial interval if additionally bp = 0; fails if the elements have not been peeked yet

Sourceval get_loc : int -> 'a t -> Loc.t

Return location of an already peeked element at some position counting from 0; fails if the element has not been peeked yet

Lifted usual function on streams

Sourceval count : 'a t -> int

Sourceval peek : 'a t -> 'a option

Sourceval npeek : int -> 'a t -> 'a list

Sourceval junk : 'a t -> unit

consumes the next element if there is one

Sourceval njunk : int -> 'a t -> unit

njunk n strm consumes n elements from strm

Sourceval next : 'a t -> 'a

next strm returns and consumes the next element; raise Stream.Failure if the stream is empty

Other functions

Sourceval peek_nth : int -> 'a t -> 'a

peek_nth n strm returns the nth element counting from 0 without consuming the stream; raises Stream.Failure if not enough elements
