Ell is a library to write EBNF grammars as C++ code for quick development of LL(n) parsers or similar applications. It is not a tool to generate parsers (like ANTLR): the grammar you write is directly embedded into your C++ code. The core library is very light (less than 2000 lines of headers) and written in generation templates to achieve the fastest execution. The service provided by Ell is very similar to what Boost Spirit provides, but with a simpler object model, and without the need of the Boost library (it only depends on STL).
Templum is an extremely lightweight, simple yet powerful, and fast templating engine for PHP. It re-uses the power of PHP itself for rendering templates, but provides additional features making it easier and more secure to write templating code. Rendering templates using Templum is very fast; it approximates native PHP rendering speed for include() statements.
