val show_buffer : block_out:(Ecaml.Position.t * string) list -> unit

val show_point : unit -> unit

Print buffer contents with the point shown as a solid block.

val show_active_region : unit -> unit

Print buffer contents with the start and the end of the active region replaced by delimiter characters (double angle brackets).

val show_with_overlay_text : unit -> unit

Print buffer contents with the before-string and after-string properties from any overlays rendered as though they were present in the buffer. Also, mark any text specified as invisible through overlays (but not through text properties). This does not reflect the actual contents of the buffer, but rather how the contents would appear to the user.
