Dylan M. Taylorandshuff57 49dfd6ddc0 craft-odf: OpenDocument Text documents on craft-flow (feature text), from WordCraft (stacked) (#1064)
* Add craft-wordmodel: WordCraft's document model without its editing code

WordCraft's crates/doc (wordcraft-doc, at 07f97737) moved as it is, so the DOCX,
RTF, ODT and other text-format crates can read into and write from one model.
Module paths, type names and serde attributes are unchanged: an app that
re-exports the crate keeps its native file format.

Left in the app: range editing (edit.rs), IME text and equation editing. Not
model, and already in craft-libs: code pages (craft-rtf), the ZIP entry-count
check (craft-opc), the compound-file guard (craft-cfb). The paragraph walks
moved to walk.rs and the unit helpers of wordcraft-geom to geom.rs.

* craft-wordmodel: math_tree, the arguments of an equation node and a walk over its runs

The DOCX reader and writer walk an equation's runs. The walk and the child
accessors it uses were in WordCraft's equation editor (math_edit.rs), which
stays in the app; they are structure, not editing.

* craft-mime: detect, for bytes that name no character set

is_text, decode (BOM, unmarked UTF-16, UTF-8, else the legacy encoding
the bytes look like), legacy and legacy_label, behind a detect feature
that brings in chardetng. Moved from WordCraft's crates/formats/src/txt.rs
at 06c2ae6f with its text-sniffing tests. Also charset::is_known, so a
caller can tell a label decode would read as UTF-8 from one it knows.

* craft-wordmodel: keep the document operations (edit.rs) with the model

The DOCX and RTF readers use them: alternative-format chunks are merged into
a document with adopt_blocks, and a reader formats ranges with format_range
and inserts objects. They operate on the document, not on a view, so they
belong beside it. The tests that drove them come back with them; the
paragraph walks stay in walk.rs and edit re-exports them.

base64 0.23, as WordCraft and craft-offcrypto use.

* craft-codepage: one table per legacy code page, for craft-rtf, craft-dxf and craft-mime

craft-rtf and craft-dxf each carried tables for DOS 437, 737, 850, 852 and
857 (and craft-rtf one for 866). They are now one set in craft-codepage,
which takes craft-rtf's codepage module (Windows and Mac tables, OEM glyphs,
font charsets) and craft-dxf's DOS tables. craft_rtf::codepage re-exports it
unchanged; craft-dxf keeps its $DWGCODEPAGE names and Decoder and looks the
DOS tables up there.

Every byte of every code page either crate decodes is unchanged: the
public decoders of both crates were dumped over all 256 bytes of each page
(and the East Asian pairs) before and after, and the dumps are identical.

craft-mime now reads the DOS pages by their IANA names (IBM437, cp850,
ibm-852, 857...), which it read as UTF-8 before.

* Add craft-math: the equation tree with OMML, MathML, LaTeX and UnicodeMath

The math tree, LaTeX, linear-format, symbol and tree-walk modules come
from craft-wordmodel (storytold/craft-libs#963, WordCraft's crates/doc at
07f97737) unchanged, with the run colour (Rgb) and the symbol-font tables
they use. MathML is WordCraft's crates/formats/src/mathml.rs and OMML is
WordCraft's crates/docx/src/read/math.rs and write/math.rs (06c2ae6f /
07f97737), moved onto craft-xml. The HTML-specific MathML tests stay in
WordCraft; the rest moved with the code.

mathml::parse and omml::parse/read_str/write_str are new: string entry
points for callers that have no tree of their own.

* craft-math: read MathLive's and other spellings of LaTeX math commands

\abs{...} (an absolute value), \lvert \rvert \lVert \rVert, \nparallel,
\backprime, \infinity, \cross, \differentialD, \exponentialE and
\imaginaryI (MathLive's d, upright e and i), \emph, \textsf, \hbox,
\mathnormal and \underleftarrow / \underrightarrow /
\underleftrightarrow were unknown and read as literal text. They are read
as equaSHion's typed-input parser reads them (storytold/craft-libs#29).

* craft-math: equaSHion's equation corpus as test data

corpus/equations.tsv, corpus/latex.tsv and the OMML samples of
storytold/craft-libs#29 (7a6ef6b9), unmodified.

* craft-math: corpus round trips, GridCraft's OMML cases, entry points and limits tested; README

The corpus equations go through OMML, MathML and LaTeX and back; the OMML
samples are written back as kept and from the tree. GridCraft's OMML to
LaTeX test cases (crates/xlsx/src/omml.rs) give LaTeX that reads back the
same through the tree. omml::parse and read_str are tested against other
prefixes, the strict namespace, kept OMML, junk, the element cap and deep
nesting.

* Add craft-flow: the flow model the text formats map to, on craft-wordmodel

WordCraft's crates/formats/src/model (07f97737) moved as it is: Flow,
FBlock, Para, Inline, Fmt, tables and cells, pictures, to_doc and
from_doc, picture sniffing, colours, base64 and the Dropped report. Only
the paths changed (wordcraft_doc is craft_wordmodel); the report helpers
are public so the format crates can call them; the image re-encoding
helper stays with WordCraft's RTF writer.

* Add craft-markdown: Markdown read and written, on craft-flow

WordCraft's crates/formats/src/markdown (07f97737) with its 35 tests,
moved onto craft-flow and craft-wordmodel. Character references come from
craft-html. The table cell budget lives in craft-flow, which names it in
its warning. Two test lines that wrote plain text through WordCraft's txt
module stay in WordCraft.

* WIP: craft-latex sources from WordCraft (unmodified)

* Add craft-latex: LaTeX documents read and written, on craft-flow

WordCraft's crates/formats/src/latex (07f97737) with its 21 tests, moved
onto craft-flow and craft-wordmodel; bytes are decoded by craft-mime's
detect. The LaTeX parts of WordCraft's cross-format tests (nesting,
column specs, labels, no TeX commands from the document, the fuzz and
round-trip properties) come along as tests/hostile.rs. The ligature test
builds its three-font paragraph as a flow instead of reading HTML.

* craft-math: latex_text, LaTeX math and the linear format converted as text

WordCraft's crates/formats/src/latex/math.rs (07f97737): the converter its
LaTeX document reader and writer use, which keeps the source's spacing.
It moves here so craft-math is the one place that converts LaTeX math;
craft-latex calls it, and its output does not change. Its tests (from
WordCraft's latex tests and cross-format tests) come along.

* craft-math: latex_text's group finders are public, for craft-latex's length parser

* craft-latex: math through craft_math::latex_text; label timing test by ratio

The document math converter moved to craft-math (#1040) unchanged; this
crate calls it there (and its length parser uses its group finders), so
export output is the same. The label test compared one read with a
ten-second wall clock and failed on a loaded machine; it now compares the
fastest of three reads of 25,000 and 100,000 labels, which a linear read
keeps near 4x and a quadratic one near 16x.

* Cargo.lock after the merge

* WIP: WordCraft's HTML document reader and writer, unmodified (crates/formats/src/html at 07f97737)

* craft-html: HTML documents on craft-flow, behind a flow feature

WordCraft's crates/formats/src/html (07f97737) as craft_html::doc: the
tag-soup builder, CSS subset, ruby and MathML reading, page decoding and
the writer, with its 44 tests. It reads tokens from this crate's
tokenizer through a small adapter (decoded text and attributes, names in
lower case) instead of its own lexer, and its character references are
this crate's. Lexer::set_pos is new: the ruby reader hands a token back.
The HTML parts of WordCraft's MathML and cross-format tests come along as
tests/doc.rs, the linear-time check as a ratio.

* Cargo.lock after the merge

* WIP: WordCraft's ODT reader and writer, unmodified (crates/formats/src/odt at 07f97737)

* craft-odf: OpenDocument Text documents on craft-flow, behind a text feature

WordCraft's crates/formats/src/odt (07f97737) as craft_odf::text, with
its 467 tests. Moved onto this crate's own layers: packages are read with
Package and written with PackageWriter, password protection is crypt
and flat files are flat (the copies in the WordCraft module are gone),
and its XML event stream is craft-xml's pull reader instead of quick-xml.
Paths: craft_flow, craft_wordmodel, craft_math::mathml, craft_metafile.
The date helper it borrowed from the spreadsheet reader came along.
Tests read packages through Package instead of zip.

* craft-math: operator names take their LaTeX scripts directly again (restores #1019)

#1019 (22161d2d) wrote \sin^2\theta as \sin ^{2}{\theta } so it reads back as
the same tree. The squash merge of #1038, whose branch predated it, put
math_latex.rs and the corpus test back as they were before. This applies
#1019's change again, unchanged, with its test.

* Cargo.lock: craft-html's flow dependencies
