# 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. [tame-core](https://github.com/lovullo/tame-core) is
TAME's core library, and [hoxsl](https://savannah.nongnu.org/projects/hoxsl)
was developed as a supporting library.


## "Current"
The current state of the project as used in production is found in
`src/current/`.  The environment surrounding the development of this
project resulted in a bit of a mess, which is being refactored into
`src/` as it is touched.  Documentation is virtually non-existent.


## Documentation
Compiled documentation for the latest release is available via our GitLab
mirror, which uses the same build pipeline as we do on our internal GitLab
instance.  Available formats are:

- [Multi-page HTML][doc-html]
- [PDF][doc-pdf]
- [Info][doc-info]


## Hacking
Information for TAME developers can be found in the file `HACKING`.
