Template Data Interface (TDI, /ʹtedɪ/) is a markup templating system written in Python with (optional but recommended) speedup code written in C. Unlike most templating systems, TDI does not invent its own language to provide functionality. Instead, you simply mark the nodes you want to manipulate within the template document. The template is parsed, and the marked nodes are presented to your Python code, where they can be modified in any way you want.
PhpPeanuts is a framework for developing database-backed applications in PHP. Rather than building an application from the bottom up, you initially only build domain model classes in which you specify properties, relationships, and database table names in metadata. The framework dynamically scaffolds getters and setters, persistency, navigation over relations, and input and delete validation. The abstract user interface instantly offers a rich set of pages for searching, browsing, drilling down, editing and reporting over your domain model. From there on you extend and refine both the domain model and the user interface to make it what you want by defining specialization classes and overriding inherited methods.
