Module Biocaml_lines.Buffer (.ml)

module Buffer: 

Buffer used to parse strings into lines.
type t 
The buffer handle.
exception No_next_line
The exception thrown by next_line_exn.
val make : ?filename:string -> unit -> t
Make a new empty buffer. The optional filename is used only for error reporting; it should be set to the name of the file, if any, from which you will feed the buffer.
val feed_line : t -> Biocaml_lines.item -> unit
Feed the parser with a line.
val feed_string : t -> string -> unit
Feed the parser with an arbitrary string buffer.
val queued_lines : t -> int
Get the number of lines ready-to-use in the buffer/queue.
val is_empty : t -> bool
Tell if the parser's buffers are empty or not. For instance, when there is no more content to feed and next_line returns None, is_empty p = true means that the content did not end with a complete line.
val peek_line : t -> Biocaml_lines.item option
Peek at the next line, without removing it from the buffer.
val next_line : t -> Biocaml_lines.item option
Get the next line.
val next_line_exn : t -> Biocaml_lines.item
Get the next line, but throw No_next_line if there is no line to return.
val current_position : t -> Biocaml_internal_utils.Pos.t
Get the current position in the stream.
val contents : t -> Biocaml_lines.item list * string option
Return any remaining lines and the unfinished string, without removing them from the buffer.
val empty : t -> unit
Empty the buffer. Subsequent call to contents will return ([], None).
