VXL (the Vision-something-Libraries) is a collection of C++ libraries designed for computer vision research and implementation. It was created from TargetJr and the IUE with the aim of making a light, fast and consistent system. VXL is written in ANSI/ISO C++ and is designed to be portable over many platforms.
ANTLR, ANother Tool for Language Recognition, formerly known as PCCTS, is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing actions in a variety of target languages. ANTLR automates the construction of language recognizers. From a formal grammar, ANTLR generates a program that determines whether sentences conform to that language. In other words, it's a program that writes other programs. By adding code snippets to the grammar, the recognizer becomes a translator or interpreter. ANTLR provides excellent support for intermediate-form tree construction, tree walking, translation and provides sophisticated automatic error recovery and reporting.
The ObjectARX® programming environment provides object-oriented C++, C# and VB .NET application programming interfaces for developers to use, customize, and extend AutoCAD® software and AutoCAD-based products like AutoCAD® Architecture, AutoCAD® Mechanical, and AutoCAD® Land Desktop software.
Coco/R is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k.
