MetaCC is an annotation based lexer (scanner) and parser generator suitable for processing a wide range of languages, from small domain-specific languages to big ones like Java. Actions may be written directly as annotated Java methods. It contains examples of an expression language and Java 5 grammar.
MIB Smithy is an application for SNMP and COPS developers, MIB and PIB designers, and Internet-draft authors. It provides a GUI-based environment for designing, editing, and compiling MIB and PIB modules according to the SMIv1, SMIv2, and COPS-PR-SPPI standards. It accelerates the development process by providing an easy-to-use GUI-based environment for developing the specifications without the syntax and formatting concerns of editing the modules by hand. It includes a number of built-in basic SNMP management tools, XML support, and (with MIB Smithy Professional) support for custom compiler output formats.
Zend Framework Installer is a PHP class that can be used to setup files for an application based on the Zend framework. It creates a common directory structure as recommended in the Zend Framework's manual. The class can also generate a bootstrap file and the index controller with its view.
allspice is a set of Java libraries that allow you to define and implement a language that runs on top of the JVM. The packages define a YACC-like grammar and an underlying high level programming abstraction. One need never know about JVM internals to implement a new language. In addition, these compilations can be "on the fly". You can compile and execute without an intermediate class file.
Rhope is a dynamically typed dataflow programming language that also borrows some ideas from other paradigms. Unlike mainstream programming languages, statements are not necessarily executed in the order they are written, but instead based on their dependencies. Statements that do not share dependencies run in parallel. Most operations have value semantics (i.e. modifying an object makes a copy rather than changing the original) making this parallelism safe. For managing global state, Rhope has a transaction mechanism.
