This has been the ultimate goal for the pipeline for some time---the ability to declaratively define the lowering pipeline in a way that is clear, concise, and is correct by definition. The reason that the lowering pipeline required so much boilerplate was because of the robust types involved, which ensures that everything in the pipeline is compatible with one-another---it's not possible to construct a pipeline that will not work. Of course, there is nuance involved in some cases---I didn't want to include the `until` clause, which makes it fail the "obviously correct" criterion, but that can be improved over time. This only abstracts away `load_xmlo` and `parse_package_xml`; next I'll have to evolve the abstraction to support lifetimes for `lower_xmli`'s `AsgTreeToXirf`. That pipeline also ends with a custom sink that really ought to become its own parser, but I don't want to jump down that rabbit hole right now, so we may just support custom sinks for now with the intent of removing it in the future. This has been a long time coming. The ultimate goal is that you should be able to look at the parser pipelines to have a clear, high-level overview of how everything fits together. I'm not generating documentation yet, but that'll help serve as a guide as well. 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.
