TAME Core

Core library for TAME, providing generic abstractions for common operations.

This library has accumulated a bit of cruft, is disorganized, and has not been substantially refactored to take advantage of new language features. It is a work in progress.

This is also of limited use to others outside of LoVullo, since TAME has not yet been liberated.

BC Warning: Backwards-incompatible changes will be made in minor/revision releases until the release of v1.0.

Features

• BDD abstraction;
• Classification match manipulation;
• Common operations on numbers;
• Conditional evaluation helpers;
• Core primitive declarations;
• Interpolation;
• Interval mapping;
• Matrix and vector manipulation;
• Query matrices as data tables;
• Value mappings; and
• Other miscellaneous stuff.

What is TAME?

TAME is The Adaptive MetalanguagE, a programming language and system of tools designed to aid in the development, understanding, and maintenance of systems performing numerous calculations on a complex graph of dependencies, conditions, and a large number of inputs.

This system was developed at LoVullo Associates to handle the complexity of comparative insurance rating systems. It is a domain-specific language (DSL) that itself encourages, through the use of templates, the creation of sub-DSLs. TAME itself is at heart a calculator—processing only numerical input and output—driven by quantifiers as predicates. Calculations and quantifiers are written declaratively without concern for order of execution.

The system has powerful dependency resolution and data flow capabilities.

TAME consists of a macro processor (implementing a metalanguage), numerous compilers for various targets (JavaScript, HTML documentation and debugging environment, LaTeX, and others), linkers, and supporting tools. The input grammar is XML, and the majority of the project (including the macro processor, compilers, and linkers) are written in XSLT. There is a reason for that odd choice; until an explanation is provided, know that someone is perverted enough to implement a full compiler in XSLT.

More information will become available as various portions are liberated during refactoring; hoxsl is a product of what is now known as TAME.
