FortranAS

FortranAS is an Antlr4 🔗 powered FORTRAN parsing and code clone detection tool. FortranAS leverages grammars-v4 🔗 to generate parsers and lexers and supports any FORTRAN version with available corresponding grammars.

FortranAS Key Features

• Docker build and runtime environment
• Docker build context for Antlr4 and Grammars-v4 (See: Antlr4 Build Context)
• Extensible FORTRAN Grammars via grammars-v4 🔗. FortranAS supports any FORTRAN version with corresponding grammars.
• FORTRAN source representation as Antler4 parse tree
• Conversion of concrete Antlr4 parse tree to generic tree data structure
• Translation of parse tree to abstract syntax tree representation
• Serialization of all data structures(parse trees, abstract syntax trees, Antlr4 tokens) to: JSON, GraphViz DOT (for tree visualization), text file (tree terse string)
• Code clone detection with abstract syntax trees approach using natural language processing metrics such as BLEU Score and Jaro-Winkler-Similarity
