Mike Gerwitz 36a3e348b6 core: Add comparison operators for table query predicates
This is fairly primitive support and it completely sidesteps the bisect
algorithm for now.  The next commit will abstract this a little bit further
to make it less awkward to use.

* core/test/core/vector/table.xml: New test cases.
* core/vector/filter.xml (CmpOp): New typedef.
  (mfilter): Document that bisecting will not happen unless `CMP_OP_EQ'
    is used.  Implement that restriction.
    [op]: New parameter.  Provide it to `mrange'.
  (_mfilter, _mrange_cmp): Rename from `_mfilter'.  Implement new comparison
    check based on `op'
    [op]: New argument.
* core/vector/table.xml (_when_)[@op@]: New param.  Add it to the produced
    vector.
  (_mquery): Unpack op (from `_when_') in call to `mfilter'.

TAME

TAME is The Adaptive 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 R-T Specialty (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 XSLT. There is a reason for that odd choice; until an explanation is provided, know that someone is perverted enough to implement a full compiler in XSLT.

"Current"

The current state of the project as used in production is found in src/current/. The environment surrounding the development of this project resulted in a bit of a mess, which is being refactored into src/ as it is touched. Documentation is virtually non-existent.

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
