关于换行符问题 重要

需要吧file.read()
换成file.readlines()并传递给扫描器，
不然无法处后续的行数问题

Look for where file.read() is used in the parser code, likely in the scanner/tokenizer. Replace it with file.readlines() to enable line number tracking. Check the scanner's initialization to see how it expects input. Run existing tests to ensure the change doesn't break parsing.
