Fakiir helps a programmer to expose an API with its methods and properties, generating code for object introspection which can be used by an object-oriented application to offer external access to its own public functions. It analyzes an OO header using a Lex/C grammar parser and generates C++ code from it.
The "Faster Java Serialization" project aims to provide faster Java serialization by inspecting classes and generating tailor made serialization code on the fly. This serialization code is reused for every object of the same class. Objects are serialized to a NIO ByteBuffer, eliminating the need for numerous memory copies that take place during normal serialization to files or network. Currently, there are some limitations on the kinds of objects that can be serialized.
Faust AUdio STreams is an expressive functional programming language for realtime audio signal processing. The Faust compiler translates DSP specifications into efficient C++ code. A variety of platforms and plugin formats are supported. A single Faust specification can be used to easily generate JACK and ALSA applications, as well as LADSPA, MAX/MSP, PD, Q, SC, and VST plugins. In addition to C++ code, the Faust compiler can also generate SVG block-diagram representations as well as XML descriptions.
Felix is a programming language with a fully featured purely functional subsystem embedded in a a traditional Algol-like imperative programming system. The system features garbage collection, static typing, parametric polymorphism, overloading, regular expression matching, and a lot more. A scripting harness is used to invoke source files, but fully compiled binary shared libraries are generated, yielding both rapid prototyping and high performance. Seamless binding of C/C++ code makes interfacing existing libraries easy. Control inversion provides language-level cooperative multi-tasking.
FireStorm/DAO is a Java Code Generator that can import existing database schemas (from a SQL script or from a live JDBC connection) and can then generate a complete persistence tier. It generates Java source code and configuration files that developers would otherwise have to write by hand, and that is compliant with the Data Access Object (DAO) design pattern.
FleXML reads a DTD (Document Type Definition) describing the format of XML documents and produces a validating XML processor with an interface to support XML applications. Because the DTD is known in advance, the C code generated is much more efficient than equivalent code using an API such as SAX.
