Mike Gerwitz fbf786086a tamer: parse::Parser (lower_while_ok): New method
This introduces a WIP lowering operation, abstracting away quite a bit of
the manual wiring work, which is really important to providing an API that
provides the proper level of abstraction for actually understanding what the
system is doing.

This does not yet have tests associated with it---I had started, but it's a
lot of work and boilerplate for something that is going to
evolve.  Generally, I wouldn't use that as an excuse, but the robust type
definitions in play, combined with the tiny amount of actual logic, provide
a pretty high level of confidence.  It's very difficult to wire these types
together and produce something incorrect without doing something obviously
bad.

Similarly, I'm holding off on proper docs too, though I did write some
information here.

More to come, after I actually get to work on the XmloReader.

On a side note: I'm happy to have made progress on this, since this wiring
is something I've been dreading and wondering about since before the Parser
abstraction even existed.

Note also that this makes parser::feed_toks private again---I don't intend
to support push parsers yet, since they're only needed internally.  Maybe
for error recovery, but I'll wait to decide until it's actually needed.

TAME

TAME is The Algebraic 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 Ryan Specialty Group (formerly 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) is written in a combination of XSLT and Rust.

TAMER

Due to performance requirements, this project is currently being reimplemented in Rust. That project can be found in the tamer/ directory.

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:

Getting Started

To get started, make sure Saxon version 9 or later is available and its path set as SAXON_CP; that the path to hoxsl is set via HOXSL; and then run the bootstrap script:

$ export SAXON_CP=/path/to/saxon9he.jar
$ export HOXSL=/path/to/hoxsl/root

$ ./boostrap

Running Test Cases

To run the test cases, invoke make check (or its alias, make test).

Testing Core Features

In order to run tests located at core/test/core/**, a supporting environment is required. (e.g. mega rater). Inside a supporting rater, either check out a submodule containing the core tests, or temporarily add them into the submodule.

Build the core test suite summary page using:

$ make rater/core/test/core/suite.html

Visit the summary page in a web browser and click the Calculate Premium button. If all test cases pass, it will yield a value of $1.
