LibreOffice's compatibility option (ODF AddParaTableSpacingAtStart, Word's
w:suppressSpBfAfterPgBrk read the other way round). Off, the block that opens a
page loses its space above however the page broke — probed by flipping the flag
in one 63-page document, whose chapter heading then moved from 25.4mm to 20.0mm,
which is where the editor had been drawing every one of them. On is the default
both products write, and both formats carry the flag back out. Fixture 244 → 160.
Probed: a header of one 10pt line with a 12mm bottom margin puts the body at the
band's min-height, not 12mm lower, and a footer's trailing margin is dropped the
same way — while a margin between two of the zone's paragraphs counts in full
(two lines 12mm apart give a 20.16mm band). The collapsed zone paragraph carries
only the margins between its source paragraphs now. One 16-page fixture went
183 reports → 5, its body having sat 10.3mm low on every page.
The edge→zone distance was document-wide, so an index whose header starts 4cm
down had its body open 14.5mm too high and the page under it followed. HfSet
carries the section's own pair (and its first page's, where the page style hands
over): ODF's page-layout margin is that distance, Word's is w:pgMar
w:header/w:footer, and both exports write it back.
Both importers capped every side at 10cm, which is the Layout panel's limit and
no file's: a back cover pushing its last lines to the page foot with a 21cm top
margin rendered 11cm high. fitMargins caps only what would leave the page no
strip of text at all, and the zone distances follow the page's own height.
The outline level's character style, its indent and the stop its label's tab
runs to were never read, so a 96pt grey chapter number rendered at the
heading's own size and everything under it sat ~30mm high. The label is an
inline block now — one set larger than its heading grows the line as both
products grow it — hung out of the paragraph's indent with the level's stop as
its minimum width. text-indent inherits into that block and would shrink it by
exactly what it hangs out, so the label zeroes it. Both formats carry all of it
back out (ODF's label alignment, Word's w:suff / w:ind / w:rPr).
A numbered thesis lost every "1.", "2.1.4" and "A." on import: the outline
definition was read as a list wrapping headings and dropped. It is now a
document-level definition on the style sheet (format, prefix, suffix,
display-levels, start per level), drawn by CSS counters that reset down the
levels, and carried by both formats — ODF's text:outline-style, Word's
multilevel numbering bound to the heading styles. The contents rows count the
same way, since no text walk can read a CSS counter.
LibreOffice's Left Page / Right Page chain into each other through
style:next-style-name, which was read as the different-first-page idiom: one
master's geometry and zones governed the whole section, so a book-style body
lost its running head on every second page and its inner/outer margins with
it. A next-style cycle now becomes one mirrored setup — the right page's
geometry, the left page's zones as the even variant — and style:page-usage
left/right marks the margins as mirrored.
ODF's table:align="margins" means the table spans between its own margins, and
style:width is then the width the producing page had. Read as a left-aligned
table, the undeclared right margin was derived from that width against ours and
the table came out narrow — measured 12.4cm on a 14.7cm text width, its column
rule 10.4mm left of where LibreOffice draws it.
Writes agile encryption with Word's own parameters (AES-256-CBC in 4096-byte
segments, 100000 SHA-512 rounds, HMAC integrity) into a compound file built
here — cfb.ts, MiniFAT and DIFAT included. Reads that and the older standard
encryption LibreOffice writes, whose package is AES-ECB. Verified both ways
against LibreOffice.
Writes LibreOffice's whole-package form: AES-256-GCM keyed by Argon2id over
SHA-256 of the password, the deflated package as one encrypted-package entry.
Reads that plus the per-entry AES-CBC/GCM form with PBKDF2 that every earlier
version writes; the nonce sits ahead of the ciphertext, which no manifest says.
Blowfish and unknown algorithms report an unsupported-encryption error.
ReviewMarginLayer draws the cards in a strip right of the page, at the height
of the line each belongs to, with a dashed leader running through the gap
under it. A balloon is pushed down by the one above (balloonStack, measured
per card, unit-tested) and the column belongs to its page, so it never runs
past the sheet. The strip is only reserved where the margin has something to
show; the smoke test guards a card's content against its box.
storage/markup holds the display mode (all, simple, none, original) plus, per
kind, whether it shows and where its cards go; markupView folds that into what
the page acts on. Bars, leader and both panes ask reviewItems instead of the
document, the page takes the hiding attributes, and trackChanges drops its
author decoration where the mode shows a finished text.
A TOC field regenerates its rows from the styles named `toc 1`…`toc 9`, and its
cached rows are skipped on import — so those styles were never seen and the index
fell back to the editor's 0.5cm per level, dropping the file's space-after with it.
Measured on a 60-row index: a 5.1mm row pitch against LibreOffice's 6.9mm.
They now land as Contents 1…10, and the DOCX export writes the rows back under
them instead of the fallback indent.
Word caches a BIBLIOGRAPHY field's rows as a w:tbl inside the field, and
only the field's paragraphs were skipped — so the list arrived once as the
regenerated index node and once as that table. Measured on a 49-page
document: two pages of duplicate. StyleName IEEE now reads as the numbered
style it is, so its citations show [1] instead of the source key.
The clipboard carries HTML, and in an HTML string any block tag inside a
<p> closes it — so a copied box arrived as loose paragraphs. It is now
serialized as an inline span carrying its blocks as JSON, read back by a
matching parse rule; its plain text stays in the span for readers that
cannot take the attribute back.
Entries were stored as an HTML string, where any block tag inside a <p>
closes it — so a copied text box, which holds blocks, lost its place in
the line. They now keep the slice's nodes; an entry written earlier keeps
its HTML string, which insertContent takes just as well.
A box that starts its paragraph was a trap: there is no text position beside
it, so the browser pulled the caret meant for the box's own place in the line
into the frame and everything typed there landed inside it.
A frame nobody is editing is now an atom to the browser — a contenteditable
node decoration, dropped while the caret is in its text, the frame placing the
caret itself on the click that enters it. ArrowLeft/ArrowRight at the box's
first and last text position step out to it. The decoration walk enters blocks,
without which it never reached an inline box at all.
A box in the line is a character its paragraph places, as a picture is, so the
three frame-toolbar buttons were the paragraph's own alignment under a frame
icon — a second place to look for the same thing. They now show for the band
wrap alone, where nothing else can express the position.
The ordinary command needed one correction to carry that: a selected box is one
node whose range covers its own paragraphs, so aligning it moved the frame and
re-set its text in the same keystroke.
textBox becomes an inline node carrying block content, like the frame both
formats write, so "in line with text" really is in the line and a box reaches
a table cell or a list item through their paragraphs. Both exports write it
where it sits (an as-char draw:frame / a wp:inline drawing) and both imports
leave it there, which drops the hoisting machinery on either side.
Two guards the schema cannot express: no box inside a box, and a selection
reaching into a box grows to the box's bounds rather than dissolving it.
A break between spanned rows stretched the cell across the gap: the
merged table drew over the page gap and the next page's header. A
group too tall for a page still breaks per row. An in-flow text box
took the same treatment for floats — CSS lays a block box over one
instead of beside it, which had the vertical frame covering its
neighbour. Both match LibreOffice's render of the same document.
The DOCX import dropped left as the default and kept right regardless
of w:bidi; an rtl paragraph's default edge is right. start/end read as
physical left/right — LibreOffice spells an rtl paragraph's physical
left as w:jc="start" (probed via its own DOCX export).
utils/chapterField owns the per-zone reading (header = the chapter at
the page top, footer = the last begun) so the probed LibreOffice
semantics is unit-tested; the DOM measurement feeding atTop stays in
Editor.svelte.
The margin carve-out under a page border, the bare note anchor and a
Writer frame keeping a list and a nested image through an soffice
re-save each get an asymmetric assertion — a symmetric export/import
pair had hidden all three.
Without a parent chain to the Frame style LibreOffice read the box as a
drawing object, whose text loses lists, nested images and borders. The
frame takes fo:background-color/fo:border and its writing mode in the
graphic properties; an inline box's centring rides the anchor paragraph.
The import reads the frame spellings back and drops LO's from-top/0
respelling of the default alignment.
Word reads a \# picture with the reader's regional separators, so a
German Word took "0.00"'s dot as grouping and printed 84 as "084".
The importer now reads a picture back by its shape, whichever locale
wrote it.
Word resolves the quoted style name against the localized built-in
name, so 'STYLEREF "Heading 1"' shows a field error in any
non-English Word. The numeric argument means outline level in Word
and LibreOffice alike (probed), and the importer already reads it.
The gallery avoids presets the dropdown plus default nesting already
covers, but the default cycle itself earns its slot: once a list wears
another style, switching back needs a style to switch to. No sheet
version bump — an added built-in survives the merge on its own.
The uniform LibreOffice definitions duplicated the dropdown formats plus
default nesting. The gallery now ships patterns the depth cycle cannot
produce: the outline chains Outline I.A.1 / A.I.1, the kind-mixing
Numbering with Bullets and Checklist, and the Diamond Bullets ladder,
all on the plain 1.27cm step. STYLE_SHEET_VERSION 12 swaps stored
built-ins while user styles survive.
effectiveListLevel resolved a level only for its own node species, so a
Tab-nested <ul> under a number level kept cycle bullets while the named
ODF definition (and LibreOffice) numbered it. The level's kind now wins:
the walk numbers a <ul>/bullets an <ol> (CSS keys generalized), both
exporters resolve clones and forks through eff.kind (new ODT pass
applyListLevelKinds switches L# level species), and setListStyle retypes
the subtree. Node marker attrs still override with their own species.
Fourth style family (LibreOffice's Listenformatvorlagen): per-level model in
styles/listStyles.ts, five probed LO built-ins, listStyleName on the outermost
list, one effective-level resolver shared by the decoration walk and the export.
ODF writes the full named text:list-style into styles.xml and repoints
unoverridden lists at it (overrides keep the resolved automatic clone);
import maps named list styles back to the attr + registry, attr-free.
Probed: LO keeps the named reference and display-name across a re-save.
Cover letter, CV, invoice and meeting minutes as builder modules on a shared
builders.ts (JSON helpers + the 45mm window-envelope arithmetic), localized
en/de. They sit in the registry's SHELVED list: compiled and schema-checked
per locale by tests/unit/templates.test.ts, but not offered in the gallery
until their content is settled. Gallery gains per-template thumbnails.
A file opened without a File System Access handle (no API — Firefox,
Safari, Brave — or a template) is no longer recorded: nothing could
ever reopen it, so every click failed and dropped the entry. A startup
prune clears such stale entries. Reopening now asks for 'read' instead
of 'readwrite' (Save re-prompts on its own), and a declined permission
prompt keeps the entry — only a moved or deleted file drops it.
At the very first position of a table with no block before it, Enter
inserts a paragraph above the table and moves the caret there, as both
word processors do — previously the caret could never get before such
a table. Generic first-child check, so it also covers a table leading
a cell, text box or columns section.
styleName was kept on split, so Enter at the end of a heading left a paragraph
carrying it: drawn like a heading, absent from the navigator's outline, exported
as text:p. It is no longer kept there. setParagraphStyle also missed the name
whenever it switched the node type — a following updateAttributes looks for the
new type in the pre-chain state — so it now rides along with setNode. Levels 2–6
never reached that command at all: the digit class built from MAX_HEADING_LEVEL
(10) read as [0-1], so Heading's own Mod-Alt-N took the key and set a level with
no style; that keymap is dropped, running ahead of every plugin binding.
The id said 'classic' while the UI called the ribbon Classic and the
island Modern (beta). Type, i18n keys, comments and docs now agree;
a stored legacy 'classic' still selects the island.
Word's in-front-of / behind-text (wp:wrapNone + behindDoc) and ODF's
style:wrap="run-through" both read as a side float, so a near-column-wide
picture reserved its whole height and pushed the text 23-52mm down. They
are a wrap mode of their own now: out of flow at the static position it
was anchored at, z-order from the file (inFront). Both exports carry it
back; tests/unit/wrap-through.test.ts covers the round trip.
The image fixture 72 -> 38 over both formats and 7 pages -> 6, matching
the reference; corpus 1108 -> 1074, no other fixture moved.
Word's TOC \n and an ODF entry template naming no index-entry-page-number both
say the rows are text alone; we drew leaders and live numbers over them either
way. Carried as the node's own pageNumbers attr, off only — the node view had
the page-less row already, for the bibliography. The exports write the switch
back out: \n over the whole level range, and the ODF template drops the tab
stop with the number, which is the pair LibreOffice's dialog switches together.
Both importers drop a mark the block's style supplies, and a heading's bold was
taken as given. The registry style that renders it is the file's, though —
re-parented to Standard wherever the file declares a basedOn / parent-style-name
— so nothing supplied what the mark had been deleted for, and a 23pt title line
came out 149.7mm against LibreOffice's 161.7. Gated on that parent now; a
LibreOffice file, which writes fo:font-weight on every Heading_20_N, is
untouched. Parity corpus 1892 → 1889.
A v:rect flagged o:hr is the line itself, not a shape: its height and
fillcolor become the paragraph's borderBottom (1.5pt/#A0A0A0 where the file
names none), a real w:pBdr keeping precedence — only one line can be drawn.
It was dropped with the "Drawings were removed" warning until now, which the
changelog's gap list did not admit to either.
Both reference products define ten levels but only offer the first five;
visibleStyles() filters styleOrder for the gallery in either chrome, with a
session-only 'show all styles' toggle in the menu. A deeper level a block
already uses stays listed, so the caret always has an active style.
New in the pool: underline/strike line styles, super/subscript, caps,
textPosition, links, page breaks, footnotes/endnotes, cell shading and
vertical alignment. normalize() canonicalizes importer-generated note ids and
drops the link mark's default plain:false; FUZZ_SEEDS widens the sweep beyond
the default 50. This is the suite that surfaced the last four export/import
fixes; all 300 sweep seeds now round-trip clean on both legs.
Only a pure delete was turned into a deletion mark; typing or pasting over
a selection ran as it was, so the replaced text left the document unmarked
and rejecting the change lost the original for good. A one-step replacement
now marks its range deleted and puts the new content after it, as both word
processors do.
The document's content ended in an optional noteSection, so the content
match after the first child offered noteSection as its defaultType — and
that is what TipTap's clearNodes converts a block into. Every style command
on a top-level block past the first threw "Invalid content for node type
noteSection" and applied nothing. Spelling the same language as an
alternation puts a paragraph first again.
Replace the hardcoded node if/else chain in describeTransaction with a
NODE_LABELS map covering image, text box, formula, page break, TOC,
fields, cross-reference, index/bibliography entries, ruby and columns;
foot-/endnotes labelled via their kind attr. MARK_LABELS gains link,
comment, bookmark, character style and tracked change.
The two framework-free 0%-coverage modules: the recent-files list
(dedupe by name, eight-entry cap, corrupt-localStorage tolerance) and
the labelled undo/redo mirror against a live jsdom editor (labels per
edit kind, undo/redo moves, redo branch discarded by a fresh edit).
Found by the cross-format fuzz leg. importDocx baked the resolved cell
chain in as direct formatting even where it equals what an unset attr
already renders (0/0 spacing; single line height over a single default) —
every re-imported own file grew spacing attrs on every cell paragraph.
And a numbering level kept the first list kind it saw, so a nested bullet
list beside a nested ordered one came back ordered; a kind conflict now
forks its own numbering reference, as the ODT side mints a list style.
Ctrl+F7, Review ▸ Thesaurus and the context menu open one dialog: the
word at the caret, the sense groups it is in, click one to replace it,
and a box to look up any other word. The data is MyThes re-packed to one
group per line (de 3.0MB/37k groups, en 6.7MB/143k) — the format repeats
every group once per member, ten times the bytes. Loaded on first use for
the document's language and scanned, not indexed: ~4ms a lookup, where a
word→group index measured ~100MB of memory against the text's ~8MB.
View ▸ Multiple Pages (1–4): rows of pages filled left to right, scrolling
as one canvas, every page editable. Neither reference product stops at two —
LibreOffice takes a column count, Word fits what the window allows — and both
re-zoom for it, so a whole row is fitted when the count changes. A pane is a
grid cell clipped to one page, a view showing only a contiguous slice; two
rows of cells take turns as the upper one. Cost: columns x 2 live views, each
holding the whole document (measured: +94k nodes and +16ms per keystroke per
view at 177 pages).
A new document starts with it off and an import adopts the file's own
flag, so an editor left recording no longer marks the next document it
opens. Both formats carry it, probed against soffice: ODF on the change
registry (text:track-changes, written for the flag alone where nothing
is recorded yet), Word as w:trackRevisions in settings.xml — LibreOffice
writes and reads exactly those two, and reading w:trackChanges instead
would have found nothing.
