# Module Shell__line_buffer

    module Shell__line_buffer: sig .. end

String buffers that automatically get flushed at every line return.

    type t

    val create : ?eol:char -> (string -> unit) -> t

`create ~eol f` Create a new line buffer where f will be called once on every line. Eol is the endline character (it's possible to use a Linebuffer to process null separated strings )

    val flush : t -> unit

`flush b` Flushes any pending output to the callback function. This causes unfinished newlines to be flushed out so adding more characters after flushing might result in there looking as though there are more lines than there really were.

    val add_char : t -> char -> unit

    val add_string : t -> string -> unit

    val add_substring : t -> string -> pos:int -> len:int -> unit

`add_substring b s ofs len` takes `len` characters from offset `ofs` in string `s` and appends them at the end of the buffer `b`.
