Summary
CloneWorks prepares source code into fragments and detects clones in those fragments. Its input builder accepts Java, C, C++, C#, and Python, and can extract code at block, function, or file granularity. The detector uses a token-based method and accepts a minimum similarity threshold from 0.0 to 1.0; the repository describes a test run with Type-3 clone detection. For an index larger than available memory, CloneWorks offers a partitioned partial-index mode, though the partition size must be established experimentally. It runs on Linux, macOS, and Windows and requires FreeTXL 10.6 or later, gcc, make, and Java 7 or later. The input builder is slower on Cygwin because process creation is slower on Windows. CloneWorks is free, but its license requires acknowledgement and says copies, modifications, and derivatives must stay under the license and be distributed without charge. The license provides the software as-is without warranty. The maintainer invites questions and bug reports by email and says he is happy to assist with using CloneWorks.
Who it is for
