The ECMAScript CloneDR identifies and displays code segments within a system
that are identical or nearly identical (clones), supporting the consolidation of
clones to reduce the size and increase the clarity and reliability of the source
code. It is a member of Semantic Designs
- Dialects: ECMAScript "Microsoft" (as used by virtually all web browsers).
- Not dependent on any particular compiler or interpreter
- Works with arbitrary subsets of source code base
- Can handle thousands of source files
- Analysis can be parameterized by clone similarity threshold, clone size, maximum number of clone parameters, and other limits
- Each clone tuple characterized individually by mass, number of instances, number of parameters, similarity ratio, language syntax category, length, and location, with each instance pictured
- Produces a summary report in HTML including statistics sorted by various attributes and with links to HTML pages describing individual clones. For a sample report of detected clones in a ECMAScript package, summary report and this individual clone report.
Semantic Designs also offers other ECMAScript tools.
