Mike Gerwitz 2715f3e845 tamer: sym: Expose raw SymbolId for static symbols
This provides a child `raw` module that exposes a SymbolId representing the
inner value of each of the static newtypes.  This is needed in situations
where the type must match and the type of the static symbol is not
important.

In particular, when comparing against runtime-allocated symbols in `match`
expressions.

It is also worth noting that this commit managed to hit a bug in Rustc that
was fixed on 10/1/2021.  We use nightly, and it doesn't seem that this
occurred in stable, from bug reports.

  - https://github.com/rust-lang/rust/issues/89393
  - 5ab1245303
  - Original issue: https://github.com/rust-lang/rust/issues/72476

The error was:

  compiler/rustc_mir_build/src/thir/pattern/deconstruct_pat.rs:1191:22:
  Unexpected type for `Single` constructor: <u32 as sym::symbol::SymbolIndexSize>::NonZero

  thread 'rustc' panicked at 'Box<dyn Any>', compiler/rustc_errors/src/lib.rs:1146:9

This occurred because we were trying to use `SymbolId` as the type, which
uses a projected type as its inner value: `SymbolId<Ix: SymbolIndexSize>(Ix::NonZero)`.
This was not a problem with the static newtypes because their inner type was
simply `SymbolId<Ix>`, which is not projected.

This is one of the risks of using nightly.

But, the point is: if you receive this error, upgrade your toolchain.

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.
