perl-edit

Edit tracking primitives for incremental Perl parsing.

Overview

perl-edit provides types and algorithms for tracking text edits to Perl source code and computing their positional effects. It tracks both byte offsets and line/column coordinates, making it suitable for incremental parsing and LSP document synchronization.

Public API

• Edit -- a single text edit with start/old-end/new-end byte offsets and positions. Methods: byte_shift(), line_shift(), affects_byte(), overlaps_range(), apply_to_position(), apply_to_range().
• EditSet -- an ordered collection of edits, sorted by start position. Methods: add(), apply_to_position(), apply_to_range(), affects_range(), byte_shift_at(), affected_ranges(), len(), is_empty(), edits().

Workspace Role

Tier 1 leaf crate in the tree-sitter-perl-rs workspace. Depends only on perl-position-tracking for Position and Range types. Used by incremental parsing and document update pipelines.
