Worked on the helix-editor/helix repository, focusing on improving the Helix-term text editor’s handling of multi-line inserts with CRLF line endings. Addressed a critical correctness issue by fixing an off-by-one error in cursor calculation, ensuring accurate placement after inserting multiple lines, particularly in Windows environments where CRLF is standard. The solution involved careful adjustment of cursor logic to account for the length of line ending characters, reducing user-facing errors and enhancing editing reliability. Utilized Rust for the implementation, drawing on skills in bug fixing, line ending handling, and text editor development to deliver a targeted and robust improvement.
