perl-lsp-selection-range

Smart selection-range expansion for Perl source. It returns the nested regions an editor should select as the user expands the current selection.

Use this crate when

Use perl-lsp-selection-range if you need the selection-range algorithm itself. It is a narrow helper crate, not the umbrella provider surface.

Key exports

• selection_ranges - compute nested selection ranges for one or more cursors

Example

use lsp_types::Position;
use perl_lsp_selection_range::selection_ranges;

let ranges = selection_ranges(source, &[Position::new(3, 8)]);

Stack role
