Choose the project folder and name the files or behavior involved.
Count CRLF, lone LF and lone CR endings in a text buffer without modifying it. Check mixed endings, an empty buffer and a final line without a terminator, counting each CRLF pair only once.
Choose the project folder and name the files or behavior involved.
Describe the input, expected output and boundaries that must stay intact.
Review the proposed edits and any commands before relying on their result.
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
