There are a number of reasons for this, where the benefits do not make up for the losses. First: this is actually invoking cargo. Not only is this not necessary, but it's not desirable: cargo by default hits the network and does all sorts of other stuff, when all we want to do is invoke the executable. So the tests aren't really testing the right thing in that sense. See the previous commit for more information. The way it invokes cargo is different than the way the Makefile invokes cargo, so on my system, it's actually invoking a _different cargo_! This is causing problems, in particular with lock files, which causes my tests to fail. Importantly, this also removes a _lot_ of dependencies, which removes a lot of supplier chain risk and a lot of code to audit. This provides significant security benefits, especially given that what was being tested was rather small, and could be done in a shell script. TAMER will receive significant system testing later on. But for now, none of this was worth it. Further audits of dependencies will come later on. I've always been fairly insistent on keeping the dependency graph small and auditable, but recent supply chain attacks have given me a better way to rationalize the security risk. Further, I'm the only one on this project right now. |

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.
