This is a large change, and was a bit of a tedious one, given the comprehensive tests. This introduces proper offsets and lengths for spans, with the exception of some quick-xml errors that still need proper mapping. Further, this still uses `UNKNOWN_CONTEXT`, which will be resolved shortly. This also introduces `SpanlessError`, which `Error` explicitly _does not_ implement `From<SpanlessError>` for---this forces the caller to provide a span before the error is compatable with the return value, ensuring that spans will actually be available rather than forgotten for errors. This is important, given that errors are generally less tested than the happy path, and errors are when users need us the most (so, need span information). Further, I had to use pointer arithmetic in order to calculate many of the spans, because quick-xml does not provide enough information. There's no safety considerations here, and the comprehensive unit test will ensure correct behavior if the implementation changes in the future. I would like to introduce typed spans at some point---I made some opinionated choices when it comes to what the spans ought to represent. Specifically, whether to include the `<` or `>` with the open span (depends), whether to include quotes with attribute values (no), and some other details highlighted in the test cases. If we provide typed spans, then we could, knowing the type of span, calculate other spans on request, e.g. to include or omit quotes for attributes. Different such spans may be useful in different situations when presenting information to the user. This also highlights gaps in the tokens emitted by XIR, such as whitespace between attributes, the `=` between name and value, and so on. These are important when it comes to code formatting, so that we can reliably reconstruct the XML tree, but it's not important right now. I anticipate future changes would allow the XIR reader to be configured (perhaps via generics, like a strategy-type pattern) to optionally omit these tokens if desired. Anyway, more to come.

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.
