CloneWorks vs dcd

CloneWorks prepares source code into fragments and detects code clones in those fragments. It supports Linux, macOS, and Windows, with a token-based detection method and repository-level scan scope. Its input builder supports Java, C, C++, C#, and Python, and can extract blocks, functions, or files. The detector accepts a minimum similarity threshold from 0.0 to 1.0; the repository describes a Type-3 clone-detection test run. When an index exceeds available memory, a partitioned partial-index mode is available, though the README says its partition size must be determined experimentally. CloneWorks requires FreeTXL 10.6 or later, gcc, make, and Java 7 or later. The input builder runs more slowly on Cygwin because process creation is slower on Windows. It is free to use, with acknowledgement required; copies, modifications, and derivatives must remain under the license and be distributed without charge. The license also provides the software as-is without warranty.
