(** Sets of line positions. *)
(** This module implement sets of line positions. They allow to
efficiently find the beginning of a line and to convert offset to
line and column number. *)
exception Out_of_bounds
(** Exception raised when trying to access a position outside the
bounds of a set. *)
type t
(** Type of sets of line positions. *)
val length : t -> int
(** Returns the length of the set, i.e. the number of characters in
the set. *)
val count : t -> int
(** Returns the number of newlines in the set. *)
val of_rope : Zed_rope.t -> t
(** [of_rope rope] returns the set of newline positions in [rope]. *)
val empty : t
(** The empty set. *)
val line_index : t -> int -> int
(** [line_index set ofs] returns the line number of the line
containing [ofs]. *)
val line_start : t -> int -> int
(** [line_start set idx] returns the offset of the beginning of the
[idx]th line of [set] . *)
val line_stop : t -> int -> int
(** [line_stop set idx] returns the offset of the end of the
[idx]th line of [set] . *)
val line_length : t -> int -> int
(** [line_length set idx] returns the length of the
[idx]th line of [set] . *)
val append : t -> t -> t
(** [append s1 s2] concatenates two sets of line positions. *)
val insert : t -> int -> t -> t
(** [insert set offset set'] inserts [set] at given positon in
[set'].*)
val remove : t -> int -> int -> t
(** [remove set offet length] removes [length] characters at
[offset] in set. *)
val replace : t -> int -> int -> t -> t
(** [replace set offset length repl] replaces the subset at offset
[offset] and length [length] by [repl] in [set]. *)
