Comment And Docstring Preservation With Language Specific Parsing

via “lexical preservation and comment attribution”

Java 1-25 Parser and Abstract Syntax Tree for Java with advanced analysis functionalities.

Unique: Uses a token-position tracking system (Range objects) that maps AST nodes to their source locations and associates comments through proximity analysis, enabling round-trip preservation where code can be parsed, modified, and printed with original formatting intact

vs others: Preserves formatting better than ANTLR-based parsers which typically discard whitespace; more accurate comment attribution than regex-based comment matching because it uses syntactic context
