CloneGear

CloneGear is a clone detection tool for multiple programing languages. At present, it support C/C++, Java, Python, Javascript, and PHP. It detects clones with token-based approach but it can detect Type-3 (gapped) clones in addition to Type-1 (exact) clones and Type-2 (Renamed) clones. It also has a couple of mechanism not to detect trivial clones.

The source code is open to the public on GItHub.com.

CloneGearは複数のプログラミング言語に対応したコードクローン検出ツールです．現在のところ，C/C++，Java，Python，Javascript，およびPHPに対応しています．CloneGearは字句単位での検出手法を実装したツールですが，従来の字句単位のツールとは異なり，Type-1（完全一致）やType-2（名前変更）クローンに加えて，Type-3（ギャップを含む）クローンも検出できます．また，無駄なクローンを検出しないための工夫も行われています．

CloneGearのコードはGitHub.comで公開されています．

TinyPDG

TinyPDG is a library for building control flow graphs (CFGs) and program dependency graphs (PDGs) from Java source code. It also includes functionality to detect code clones by using the built PDGs.

The source code is open to the public on GitHub.com.

MPAnalyzer

MPAnalyzer is a software tool to modification patterns (MPs) from software repositories. A modification pattern shows a pattern that a code fragment has been changed to another code fragment by a modification. Detecting MPs will provide opportunities for reengineering or reverse engineering activities.

Currently, MPAnalyzer handles Java source code managed in SVN repositories.

The source code is open to the public on GitHub.com.

CommentRemover

CommentRemover is a simple tool for removing code comments, blank lines, bracket lines, and indents from the source files.

Currently, CommentRemover handles C, CSharp, and Java source code.

The tool is open to the public on GitHub.com.
