This is something I've wanted to do for some time, but the system is becoming hard enough to reason about (with some attempted future changes) that I require the consistency afforded by this change. It's not entirely done---as noted by the TODO for `UnnamedPkg`---but it's close, and then `AirAggregate` will just be a delegating superstate, like `ele_parse!`. Importantly, this also puts a package parser on the stack, which will work better with the stack-based scoping system being developed. It will also make it easier to fall back to a base case that I had really wanted to avoid, and will have more information on in the future: root indexing for a shared global environment for package-level identifiers. (Imports are still package-scoped, but only in appearance, by contributing to the global environment of the compilation unit during import. Well, it doesn't do that yet. The XSLT compiler works in that way.) DEV-13162 |

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