Module `Gramlib.LStream`Source

Extending streams with a (non-canonical) location function

Sourcetype ('e, 'a) t

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

Sourceval current_loc : ('e, '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 : ('e, '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 -> ('e, 'a) t -> Loc.t

interval_loc bp ep strm returns 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 -> ('e, '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 : ('e, 'a) t -> int

Sourceval peek : 'e -> ('e, 'a) t -> 'a option

Sourceval npeek : 'e -> int -> ('e, 'a) t -> 'a list

Sourceval junk : 'e -> ('e, 'a) t -> unit

consumes the next element if there is one

Sourceval njunk : 'e -> int -> ('e, 'a) t -> unit

njunk e n strm consumes n elements from strm

Sourceval next : 'e -> ('e, 'a) t -> 'a

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

Other functions

Sourceval peek_nth : 'e -> int -> ('e, 'a) t -> 'a

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