If the hash is e.g. `:class:*', it tries to parse it, which is
invalid. There's a better solution to this problem, but I don't have time
to test possibly messing this up right now.
* src/current/scripts/entry-form.js (begin): Ignore JSON parsing errors.
This same problem can occur anywhere---everything needs to be converted to
use the new `preproc:sym-lookup', but I don't have the time at the moment.
* src/current/summary.xsl (preproc:sym-lookup): New function.
(program): New toplevel variable.
(process-match)[lv:match]: Use function.
This optimization (which already existed) is supposed to remove
c:sum/c:product nodes if they contain one or fewer calculations, but it
failed to remove them when inline templates were used (because it creates,
well, a template inline).
Instead, we'll assume that any lv:* nodes handled by the preprocessor will
be okay. In the case of inline templates, they receive a preproc attribute
identifying what created it.
I hope this is a valid assumption. This will be thoroughly tested. If only
we had test cases for the preprocessor.
* src/current/include/preproc/expand.xsl: (preproc:expand)[c:sum,c:product]:
Consider optimization for `lv:*[@preproc:*]'.
The idea is to provide some guidance with how YAML test cases are supposed
to appear.
This just adds to the massive cluster that is the `entry-form.js'.
* src/current/include/entry-form.xsl (entry-form)[preproc:sym]: Add
`entry-testcase-dfn' div.
* src/current/scripts/entry-form.js: Invoke `updateParamTestcaseDfn' in
various event listeners.
(populateBucket): Invoke `updateParamTestcaseDfn'.
(updateParamTestcaseDfn, getParamTestcaseDfnElement): New functions.
* src/current/summary.css: Style `.entry-testcase-dfn'.
This existed in the old summary pages. Since we'll be having certain people
reference ids, they need to be easily visible from somewhere.
* src/current/include/entry-form.xsl (preproc:sym)[entry-form]: Add param
name and link.
* src/current/summary.css: Style it.
Long-standing bug. Didn't often see it because FF performance was
relatively poor for the Summary Pages compared to Chromium until recently,
so I didn't often load the page in it (despite it being my primary browser).
* src/current/summary.css (legend): width:auto.
If nested c:let expressions contained values of the same name, they would
all be rendered, rather than just the one intended.
* src/current/include/display.xsl (do-gen-let-list): Pass let symbol to
`_gen-let-list-item'.
(_gen-let-list-item): Render only values part of context let expression.
[letsym]: New parameter.
This was recently introduced and was noticed because c:let/@name was not
being generated under certain circumstances.
* src/current/include/preproc/expand.xsl (preproc:expand): Continue applying
templates after @dim expansion (rather than copying child nodes).
This (hopefully) prevents metadata from leaking outside of template
expansions where they are not wanted.
* src/current/include/preproc/macros.xsl (preproc:macropass): Strip
cruft (new barrier nodes) on final pass.
* src/current/include/preproc/template.xsl (preproc:expand-template):
Enclose template expansion in preproc:tpl-barrier (which is stripped on
the final pass).
(preproc:apply-template)[lv:param-meta]: Document template. "Hoist"
node (set attribute) if not contained within lv:param-copy.
(preproc:gen-param-value)[lv:param-inherit]: Consider hoisted nodes behind
barrier.
This renders template expansions as part of the calculation breakdown, which
goes a long way to understanding what the system is doing.
This further updates the hover over the breakdown to color-code based on
depth, making it easier to observe the nesting of
expressions. Sub-expressions that are toplevel results of template
expansions (nodes marked with templates) have a thicker border.
* src/current/summary.css: Add template id styling, breakdown colors, and
misc. styling.
* src/current/summary.xsl (ultra-breakdown-set): Enclose label in
span. Output template id, if applicable. Mark fieldset if templated.
This allows for debugging expansions, which are otherwise confusing and
difficult. This will be valuable information for the Summary Pages as
well (see future commit).
* src/current/include/preproc/template.xsl (preproc:expand-template): Mark
toplevel nodes after expansion.
(preproc:mark-tpl-expansion): Add templates.
Cruft left around from the symbol table refactoring long ago.
* src/current/compiler/js.xsl
(compile)[preproc:rate]: Remove template.
[preproc:class]: Remove template.
(compile-rates)[lv:package]: Remove template.
This makes me slightly uncomfortable because I haven't researched why
exactly this was not a problem before. We encountered this issue using an
inline template iterating over the symbol table yielding a `c:value-of',
which is admittedly something that we haven't done before.
Hopefully it's an isolated case.
I diffed the offending object file and the entire linked tax calculator and
they were bit-for-bit identical, so we're probably good.
* src/current/include/depgen.xsl (preproc:depgen): Do not perform dependency
generation within templates.
Other code relied on expand-sequence, but this really should be implicit,
since it is deceptively useless otherwise.
* src/current/include/preproc/template.xsl (preproc:macros): Defer
processing of inline-template with sym-set until symbol table is
available.
The primary motivation for this is to allow for template conditionals.
* src/current/calc.xsd (applyArgs): New group.
(apply,recurse): Use it in sequence.
This allows the result of a rate block to be a matrix; there was previously
no way for a named value to be assigned a matrix unless it was a parameter.
This is a bit of a kluge---the compiler won't discover the proper type
information and won't perform the proper safeguards.
* src/current/calc.xsd (sum)[@dim]: Add attribute.
* src/current/compiler/js-calc.xsl: Add xs namespace.
(compile-calc): Do not perform casting when @dim > 1.
* src/current/include/preproc/expand.xsl
(lv:rate-each): Include @dim in c:sum expansion.
* src/current/include/preproc/macros.xsl:
(c:*/@generates): Use @dim to determine symbol dimensions.
* src/current/include/preproc/expand.xsl: Parse @dim aliases (e.g. "vector",
"matrix").
If a param referenced a typedef that was imported from another package, the
summary page displayed an error rather than rendering the field. This is a
problem for testing using summary pages!
Long-standing bug with a fairly easy fix.
* src/current/include/entry-form.xsl:
(entry-form-field lv:param): Consider correct symbol (was using param
symbol, not typedef).
[typesrc]: Modernize syntax.
[typedef]: Allow for non-root-child elements. The old version of TAME
required toplevel typedefs; that's no longer the case.
This can occur during template expansion if the user is not careful in
ensuring that all generated blocks will have unique names. The error was
not useful: it failed type validation, which results in an internal error in
the compiler (from the user's perspective) and outputs no useful information
to aid in debugging.
* src/current/include/depgen.xsl
(preproc:depgen preproc:sym): User-friendly error if more than one rate
element.
[rate]: Allow multiple rate elements.
This is important to include all terminating classifications, which
include assertions. This is essential now that @keep support has been
removed; this essentially does the same thing, but in a more
sane/strict manner.
* src/current/compiler/linker.xsl (l:depgen)[preproc:symtable]:
Include package-level eligibility class in initial dependency list.
This will hopefully provide a performance boost, and is a cheap
optimization to make. The information it collected was pretty useless
in practice.
* src/current/compiler/js-calc.xsl (compile) [c:*]:
Do not encase calculations with function ancestors in debug
collection functions.
These used to be automatically added via @keep.
* src/current/compiler/linker.xsl (l:depgen): Include meta symbols.
* src/symtable/symbols.xsl (lv:meta): @pollute instead of @keep.
In particular, I want it to handle absolute import paths. It does
this for the return map; I forgot to add it here.
* src/current/compiler/map.xsl (lvmc:compile) [lvm:program-map]:
Preprocess nodes.
A classification used to be generated for each param for convenience;
this has been deprecated by the progui package generation (when `q:'
is used).
* src/current/include/preproc/macros.xsl: Remove template.
And everything else.
This is a big (important) change; it addresses one of the greatest
pains of the system.
Keeps were added during the DSL rewrite (to support symbols and such)
to work around the issue that there was no symbol-driven map; it
allowed symbols to persist disjoint from the `__yield' dependency
graph so that they could be mapped back and used by external systems.
The problem with that is that it's both messy (coupling the concept of
external dependencies with the actual code) and difficult to work
with. It had a huge performance impact on the linker for two reasons:
- Checking whether a package had already been seen and importing the
keeps on first visit was expensive because of tree searching and
manipulation; and
- _every_ keep was imported and processed by the linker, even if it
wouldn't end up being used by a particular program.
The later especially had huge performance impacts on the entire
system.
The entire dependency graph is now map-driven, with the exception of
the implicit `__yield' (which will eventually be moved into the map as
well and the magic `lv:yield' removed in favor of a template).
Performance-wise: our largest program ("dwelling") has many thousands
of symbols and the largest package imported the majority of them, many
of them unneeded, as the result of @keep subgraphs. Compilation of
the largest package within that (for the UI) took about a minute and a
half and ate up ~6GiB of RAM, for what really is a trivial task of
resolving externs, some basic symbol processing, a topological sort,
and ordering code fragments.
After this change, it takes ~15s and less than 2GiB of RAM. Still a
lot---and more improvements can be made---but much, much better.
@keep and friends was left in rater.xsd so that nothing breaks while
code is cleaned up; it'll be removed in the future.
* src/current/compiler/linker.xsl: Remove @keep support.
* src/current/dot/attr-keep.xsl: Remove now-unneeded template.
* src/current/dot/defnode.xsl: Remove @keep and related.
* src/current/include/preproc/eligclass.xsl: Remove @keep and related.
* src/current/include/preproc/expand.xsl: Remove @keep and related.
* src/current/include/preproc/macros.xsl: Remove @keep and related.
* src/current/include/preproc/symtable.xsl: Remove @keep and related.
* src/current/rater.xsd: Add TODO to remove @keep and friends.
This solves a long-standing problem whereby relative paths are not
properly resolved, leading to incorrect symbol conflicts when relative
paths to the same package vary between two imports.
See doc/notes/path-processing for an illustration.
* src/current/include/preproc/path.xsl
(preproc:resolve-relative-import): Add function.
(preproc:resolv-path, preproc:resolve-path, preproc:get-path): Add
functions to invoke existing templates.
* src/current/include/preproc/symtable.xsl (preproc:symimport): Use
`preproc:resolve-relative-import'.
* doc/notes/path-processing: Add notes.
This is a backwards-incompatible change that, like the input map,
requires the use of symbols in the return map. This will allow us to
forego the use of @keep and will have the return map be the authority
of what gets linked (all of its dependencies).
* src/current/compiler/map.xsl: Add symbol support to return-map.
This allows for the proper importing of symbols into the package
generated by the map compiler, which in turn allows for processing
their default values.
`set_defaults' wasn't in scope of maps.
* src/current/compiler/js.xsl (compiler:exit-rater lv:package):
Remove static output.
* src/current/compiler/linker.xsl (l:link-deps lv:package):
Link static after all other blocks, at highest scope within the
compiled module.
The `preproc:param-dim' template must remain for now, as it is used by
others.
* src/current/include/preproc/symtable.xsl
(preproc:symtable)[lv:param]: Extracted template.
* src/symtable/symbols.xsl
(preproc:symtable)[lv:param]: Added template.
* test/symtable/symbols.xsl
(lv:param): Scenario added.
This allows for nice formatting with newlines (to avoid excessively long
lines) without affecting the output.
* src/current/include/preproc/expand.xsl
(preproc:expand lv:classify/@desc): Normalize lv:classify/@desc whitespace
(Copyright headers will be added in the next commit; these are the
original files, unaltered in any way.)
The internal project name at LoVullo is simply "Calc DSL". This
liberates the entire thing. If anything was missed, I'll be added
later.
To continue building at LoVullo with this move, symlinks are used for
the transition; this is the exact code that is used in production.
There is a lot here---over 25,000 lines. Much of it is in disarray from
the environment surrounding its development, but it does work well for
what it was intended to do.
(LoVullo folks: fork point is 65723a0 in calcdsl.git.)
