Module NstreamSource

Stream with efficient n-lookup

Sourcetype token = {
  1. region : Pos.Region.t;
  2. token : Approx_lexer.token;
  3. newlines : int;
  4. between : string Lazy.t;
  5. substr : string Lazy.t;
  6. offset : int;
}

Enhanced tokens

Sourcetype t
Sourceval of_string : ?filename:string -> ?start_pos:Pos.Position.t -> ?start_offset:int -> string -> t

Creates a stream from a string. Make sure you don't change the string in-place after calling of_string, or anything could happen

Sourceval of_channel : ?filename:string -> ?start_pos:Pos.Position.t -> in_channel -> t

Creates a stream from a channel. Better if you don't want to block, but less efficient

Sourceval next : t -> (token * t) option

Get next token from the filter. Returns None after EOF
