Module Zed_linesSource

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.

Sourceexception Out_of_bounds

Exception raised when trying to access a position outside the bounds of a set.

Sourcetype t

Type of sets of line positions.

Sourceval length : t -> int

Returns the length of the set, i.e. the number of characters in the set.

Sourceval count : t -> int

Returns the number of newlines in the set.

Sourceval of_rope : Zed_rope.t -> t

of_rope rope returns the set of newline positions in rope.

Sourceval empty : t

The empty set.

Sourceval line_index : t -> int -> int

line_index set ofs returns the line number of the line containing ofs.

Sourceval line_start : t -> int -> int

line_start set idx returns the offset of the beginning of the idxth line of set .

Sourceval line_stop : t -> int -> int

line_stop set idx returns the offset of the end of the idxth line of set .

Sourceval line_length : t -> int -> int

line_length set idx returns the length of the idxth line of set .

Sourceval append : t -> t -> t

append s1 s2 concatenates two sets of line positions.

Sourceval insert : t -> int -> t -> t

insert set offset set' inserts set at given positon in set'.

Sourceval remove : t -> int -> int -> t

remove set offet length removes length characters at offset in set.

Sourceval replace : t -> int -> int -> t -> t

replace set offset length repl replaces the subset at offset offset and length length by repl in set.
