phpx augments PHP syntax with powerful metaprogramming constructs such as mixins, class-level eval()/macros, pattern matching, annotations and interface delegation. It also implements a simple compiler for converting this extended syntax to standard PHP. The "compiled" code can be cached to disk, allowing features to be used without any runtime performance penalty.
Entity Extractor is an application that generates ORM code from a database structure. It was originally written for generating class codes for Storm (The Canonical ORM for Python), but can be extended to generate ORM code from almost any database type. It is highly configurable, has a simple interface, and allows users to add their own features very easily.
Dextep Template Engine implements a template engine based on regular expression replacements. It can process a template with marks that define placeholders or sections using regular expressions to locate and replace those marks. Currently, it supports marks that define expressions, conditions, loops, and sub-templates files. The templates may compiled and cached to avoid processing the templates again in the future.
Erasm++, the Embedded Runtime Assembler in C++, is an Embedded Domain Specific Language (EDSL) in C++ for runtime code generation on Intel 64/IA-32 architectures. It supports complete compile-time syntax checking, and its code generators run very quickly because necessary data are computed statically. Also included are GenericDsm, a fast and generic instruction decoder library which supports "pattern matching" against the decoded instructions, and MetaPrelude, a Haskell-like lazy metaprogramming library that helps implementing EDSLs in C++.
