module Shell__line_buffer: sig .. end
String buffers that automatically get flushed at every line return.
type
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.
