The previously-existing notation for this has been removed. These will be
updated soon to account for vectors and matrices, but until then, this is
simply nonsense.
This is an unnecessary feature to maintain right now. I will include
symbols at the very beginning of the index, which is common in mathematics
texts, and may will add a table of common symbols in the future.
Stacking originally seemed like a good idea, but perhaps this does read a
bit better (and looks more like the composition operation being applied),
and composes a bit better if we needed e.g. \bicomp\bicomp{R}.
It's also less ambiguous when it's over a larger expression. For example,
\bicomp{[A]} places \circ over top of the A, which looks as if it's
[\bicomp{A}]. It's obvious what the intention is in that context, since
\bicomp{A} makes no sense, but there could be other situations where it
doesn't. With this change, it results in {[A]}^\circ.
There's a lot of change that's likely going to take place with this thing,
but it's a start. The abstract summarizes the purpose of this---to formally
define TAME in terms of algebra, first-order logic, and [ZFC] set theory.
This came about while working on compiler changes and optimizations, since
it's difficult to ensure correctness (and discover further optimizations)
without being able to formally define the language. The focus at the moment
is the classification system rewrite, which can be expressed in terms of
first order logic and set theory.
This commit contains essentially a POC with some carefully chosen
mathematical foundations (abstractions of which are subject to change) and a
basic representation of a subset of the classification system for scalars.

That is: we'll only build an object file when we try to build another object
file. This was causing problems with dependency generation, because it will
triggering compilation early.
This should have been done many years ago. This will determine if any of
the dependencies have changed for the included suppliers.mk and regenerate
it as needed, without the developer having to do so manually when imports
change.
* build-aux/Makefile.am (suppliers.mk): Invoke ant with `-q` to eliminate
"processing" messages for each and every file. This also speeds up
operation slightly.
* build-aux/gen-make: Remove information echos for each file.
These changes will allow for suppliers.mk to be regenerated automatically
without being so invasive.
The intent originally was to try to keep developers to a reasonable name
length, but generated identifiers can easily exceed this, and we further do
not support namespacing.
This can be handled at a template level instead for enforcing naming
conventions.
This had gotten quite out of date from the actual rater.xsd, which existed
outside of this repository, that is used during our build process. That was
an unintended artifact from moving files around.
That file has been removed and symlinked to this one.
Note: this really belongs in liza-proguic, and should be moved in the near
future.
liza-proguic is being modified to generate step-level packages, which are
significantly faster to build than larger ones (XSLT TAME scales
terribly). These changes handle those new dependencies.
One important thing to note with this change is that suppliers.mk now
requires proguic to have run before generation so that those generated
dependencies can be properly examined. This is a quick operation, so that
is not problematic.
This also depends on the .version.xml change that was previously made: when
the timestamp changed every time, we got into an infinite build loop.
First thing to note: this belong in liza-proguic, not here. But it's here
right now, so for now I'm making the change. The relationship between TAME
and proguic is awkward and will hopefully be improved upon in the near
future.
As for this actual change: step-level fragments will be concatenated such
that the imports will appear at the step level rather than the root.
This will be generated automatically by the Makefile. It's not appropriate
to generate in the configure script, and I do not recall why I did
so---possibly to work around the issue of delayed tab completion when it
needs regeneration?
This removes suppmk-gen in favor of more generic Makefile targets---in this
case, having `%.tdat` depend upon `rater/core/tdat.xml`, even though that's
not quite true (the %.xml file generated from it needs it). But these files
are going away soon; a pending TAME optimization branch removes support for
the underlying pattern primitive entirely; CSVMs should be used instead.
The timestamp of the file will now only be updated if the hash (version)
_actually_ changes. This allows this to be used as a target dependency
without forcing a rebuild each and every time.
This solves issues of hitting stack limits, particularly in browsers, when
querying matrices that return a large number of rows for one or more
predicates.
We were still having issues with this function when taking the positive
branch, when predicates cause many matches within tables. This was causing
us to hit stack limits in certain browsers on the Summary Page.
This converts it to an iterator so that all branches are tail-recursive, and
then enables TCO on them.
I was disappointed to find that there's little performance or memory benefit
in running our test suite.
I did say it was _experimental_ guided TRO.
This waits to perform the actual argument reassignment until after
processing the expressions associated with the new arguments, since they
will otherwise be replaced when their original values are still needed.
This change simply prevents failure in such situations, (e.g. on invalidated
fields in Liza). We'll worry about proper errors and correctness, which
ought to be compile-time, in TAMER.
