Ranges

• range() creates a new tree-sitter range.

• range_start_byte() and range_end_byte() access a range's start and end bytes, respectively.

• range_start_point() and range_end_point() access a range's start and end points, respectively.

• is_range() determines whether or not an object is a range.

Note that the bytes and points used in ranges are 0-indexed.

range(start_byte, start_point, end_byte, end_point)

range_start_byte(x)

range_start_point(x)

range_end_byte(x)

range_end_point(x)

is_range(x)

Arguments

start_byte, end_byte

[double(1)]

0-indexed bytes for the start and end of the range, respectively.

start_point, end_point

[tree_sitter_point]

0-indexed points for the start and end of the range, respectively.

x

[tree_sitter_range]

A range.

Value

• range() returns a new range.

• range_start_byte() and range_end_byte() return a single double.

• range_start_point() and range_end_point() return a point().

• is_range() returns TRUE or FALSE.
