Open Source Source Code Analysis Tools

Roslyn provides rich, code analysis APIs to open source C# and Visual Basic compilers. This enables you to access a wealth of information about your code from compilers, which you can then use for code-related tasks in your tools and applications. Roslyn dramatically lowers the barrier to entry for creating code-focused tools and applications, creating many opportunities for innovation.

A very powerful java bytecode viewer and decompiler which makes use of the javassist open source library.

Aurelia is a framework for program transformation based on a C++0x development environment. It provides libraries and tools for term rewriting, strategic programming, AST type generation, parsing.

CTokenizer accepts C++ syntax as input and outputs a vector of CToken objects, which contain a token string and a(n enumerated) token type, which can then be used to parse the input.

News: since 2015 we continue all related developments within Collective Knowledge Framework: http://github.com/ctuning/ck/wiki ICI transforms production compilers into open interactive plugin-based research infrastructure as the first step towards future intelligent self-tuning computing systems.

JASTI (Java AST Inspector) is an inspector for the OpenJDK compiler AST

JClassViewer is a viewer for class and jar files. Features: - required Java 7 or higher - used the line numbers to reconstruct an output that is near to the original output. - debugging in Eclipse - should support other languages like Scale in the future

Application for searching classpath dependencies of source code. Sometimes you do not know, which common libraries you need to compile existing java source code including transitive dependencies.

Java Cobol Lexer take a cobol source program and return it as a list of lexical tokens. Library takes source code in fixed, free and mixed formats. It recognizes standard Cobol 85.

JavacTo is a prototype tool designed to evaluate the need and value of translating java code into another programming language. An ideal language for translation is a language that supports the concept of packages, classes, interfaces, and enums as well as built-in memory garbage collection. Languages such as C# and D, are well suited as a translation “To” language. Eclipse project provided to get started. Three visitor classes provided to learn how to use JavacTo and write visitor classes. Vistor javadocs available at: http://docs.oracle.com/javase/8/docs/jdk/api/javac/tree/index.html

Turn your ES5 code into readable ES6. Lebab does the opposite of what Babel does. Lebab transpiles your ES5 code to ES6/ES7. It does exactly the opposite of what Babel does. Convert your old-fashioned code using the lebab cli tool, enabling a specific transformation. The recommended way of using Lebab is to apply one transform at a time, read what exactly the transform does and what are its limitations, apply it to your code and inspect the diff carefully. Transforms can be applied with relatively high confidence. They use pretty straightforward and strict rules for changing the code. The resulting code should be almost 100% equivalent to the original code. Transforms should be applied with caution. They either use heuristics that can't guarantee that the resulting code is equivalent of the original code, or they have significant bugs which can result in breaking your code.

PegTest is an interactive application for developing parsing expression grammars (PEGs). First, write your grammar. Then, write a test input. Finally, browse how the PEG has parsed your input.

cpp2xml is a tool to convert C/C++ definitions into XML. The main goal is to use the XML as input to code generation tools, but any other usage may be imagined.

Direct C++ to C# translator, translates one of the languages to another without compiling. Has academic aim only!!!
