This handles the bulk of the integration of the new `attr_parse_stream!` as a replacement for `attr_parse!`, which moves from aggregate attribute objects to a stream of attribute-derived tokens. Rationale for this change is in the preceding commit messages. The first striking change here is how it affects the test cases: nearly all `Incomplete`s are removed. Note that the parser has an existing optimization whereby `Incomplete` with lookahead causes immediate recursion within `Parser`, since those situations are used only for control flow and to keep recursion out of `ParseState`s. Next: this removes types from `nir::parse`'s grammar for attributes. The types will instead be derived from NIR tokens later in the lowering pipeline. This simplifies NIR considerably, since adding types into the mix at this point was taking an already really complex lowering phase and making it ever more difficult to reason about and get everything working together the way that I needed. Because of `attr_parse_stream!`, there are no more required attribute checks. Those will be handled later in the lowering pipeline, if they're actually needed in context, with possibly one exception: namespace declarations. Those are really part of the document and they ought to be handled _earlier_ in the pipeline; I'll do that at some point. It's not required for compilation; it's just required to maintain compliance with the XML spec. We also lose checks for duplicate attributes. This is also something that ought to be handled at the document level, and so earlier in the pipeline, since XML cares, not us---if we get a duplicate attribute that results in an extra NIR token, then the next parser will error out, since it has to check for those things anyway. A bunch of cleanup and simplification is still needed; I want to get the initial integration committed first. It's a shame I'm getting rid of so much work, but this is the right approach, and results in a much simpler system. DEV-13346 |

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
