CCFinder: Open-Source Token-Based Code Clone Detection System

CCFinder is an open-source token-based code clone detection system for C, C++, Java, C#, and Python code. It can efficiently detect Type 1, Type 2, and Type 3 code clones with flexibility to customize the clone detection parameters.

What is CCFinder?

CCFinder is an open-source code clone detection tool that can analyze C, C++, Java, C#, and Python code to identify similar code fragments, also known as code clones. It supports detecting three types of clones:

• Type 1 clones - Identical code fragments except variations in whitespace, layout and comments
• Type 2 clones - Syntactically identical fragments except variations in identifiers, literals, types, whitespace, layout and comments
• Type 3 clones - Copied fragments with further modifications such as changed, added or removed statements

Some key features of CCFinder include:

• Token-based clone detection approach for efficiency and scalability
• Customizable detection parameters such as minimum clone tokens, gap tokens allowed
• Flexibility in granularity of clones - from function level down to block level
• XML-based output of clone pairs/classes along with location info
• Language parsing capability for C, C++, Java, C# and Python code
• Abstraction of identifiers to enable Type 2 clone detection
• Available both as GUI tool and command line interface

CCFinder can analyze large codebases with efficient memory usage due to its incremental clone detection algorithm. With options to fine-tune the detection parameters, it provides flexibility to customize the clone detection process. The tool is useful for tasks such as code plagiarism detection, code comprehension during maintenance, and refactoring of duplicated code fragments.
