Clone Digger is a duplicate code detection tool which supports the Python language. It works on the abstract syntax tree level. Discovered clones can differ in small subexpressions; comments and whitespaces are ignored. The report on found clones is written to HTML in a two-column format with the differences highlighted. Clone digger is platform-independent. It has been tested on several open-source projects and the results indicated that about 12% of their code is covered by clones.
Perl::Critic is an extensible framework for creating and applying coding standards to Perl source code. Essentially, it is a static source code analysis engine. It is distributed with a number of Perl::Critic::Policy modules that attempt to enforce various coding guidelines. Most Policy modules are based on Damian Conway's book Perl Best Practices. However, Perl::Critic is not limited to PBP, and will even support Policies that contradict Conway. You can enable, disable, and customize those Polices through the Perl::Critic interface. You can also create new Policy modules that suit your own tastes.
The Maven-Grester plugin is a Maven2 plugin for Jester, the JUnit tester tool. It enables Jester to be executed at any valid Maven lifecycle phase in a Maven Project. It saves developers from constructing cumbersome Java classpath entries on the commandline every time they need Jester to run against JUnit Tests in the project. It can also help to dispense with a suite of scripts that may have been written to handle complex Java classpath executions for Maven projects.
AntiCutAndPaste is designed to search for text fragments that have been copied and pasted in programming language source code or plain text. It has been tested on sources from large C++, Pascal, Java, and C# (Mono) projects. The algorithms used are very fast and can handle up to three million C++ code lines in one minute. Minor modifications of code are ignored during the search. Reports are sorted conveniently by the total size of all similar fragments and there are many report customization options.
Autodia is a command line Perl application that generates UML class diagrams from source code, SQL, and database connections. It supports multiple programming languages including SQL, and can output images (using GraphViz/VCG/SpringGraph), Dia XML and Umbrello XML, or custom formats using templates.
Structure101 is a tool to understand, measure, and control software structure. It allows you to see exactly how your high-level components depend on each other and why. You can use it to find out immediately when your architecture is accidentally changed by code-level changes at the coal-face. It can help you control structural complexity, since it can measure the complexity of methods, classes, and packages and warn you when given limits are exceeded. It can also discover the locations of productivity-killing package dependency cycles.
TRex is a tool to help maintain test suites written in the standardized Testing and Test Control Notation (TTCN-3). It provides IDE functionality for the TTCN-3 core notation and supports the assessment and automatic restructuring of TTCN-3 test suites by providing suitable metrics and refactorings.
DEPS (formerly known as graph-includes) is a set of tools and libraries which allows users to extract dependency information from arbitrary material (e.g. program source files), apply various transformations to this graph, and draw it. It is typically used as helper tool for a refactoring effort, to create a graph of dependencies between groups of source files. Readability and usability of the dependency graphs are currently improved by customizable grouping of several source files into a single node, coloring of nodes belonging to given groups, and transitive reduction of the graph.
