Import maps a document's Arial to Liberation Sans (screenFontName) and the
model keeps it under that name, but only 'Arial' had an @font-face — so on a
machine without Liberation Sans installed every such run fell to the browser's
default serif. The bundled TTFs are now declared under their own family too,
as Liberation Serif already was.
Measured against LibreOffice on a 28-page fixture: its cover lines came out
7-16% narrow, 54 reports to 44.
The marker pseudo is floated into the indent instead of absolutely
positioned, so a label the indent cannot hold — a "1.1.1." outline number,
a Roman numeral — moves the first line right the way both word processors
do, rather than printing over the words it labels. Out of flow either way,
so no list line grows.
The PDF clone's injected marker follows suit, and its chain now reads the
effective numbering and walks to the outermost multilevel list: a list
numbered by a named style had none of its own and printed a bare separator.
The shape trigger stood 34px tall next to the 28px colour pickers, so its
caption sat a line below theirs; every captioned picker now shares one 32px
box and the border-width field centres on it. The shape menu was absolute
inside the band, which clips its overflow and stacks below the floating box
toolbar, so it is placed from the button's rect in the top layer, as the
colour picker already does. Its caret is the same chevron as theirs.
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.
One button per kind shows or hides it and its caret says where its cards go —
balloons or the pane, which is why the two pane toggles are gone. Display for
review carries Word's four modes beside them, and the accept / reject / walk
pairs sit under each kind. The PDF path takes the mode as page attributes, so
a printout of a page in no markup reads as the page does.
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.
Three pairings, the way both word processors draw them: a bar in the margin
beside every line a change or an open comment covers (ChangeBarLayer), the
reviewing pane's card marked and scrolled into view, and a dashed leader from
the text to that card (ConnectorLayer). The leader is drawn for the one at the
caret only, and dropped where a second pane sits between text and card.
commentIdAt/revisionIdAt compare ranges, not the marks at the caret: both marks
are non-inclusive, so the range a click on a card selects would match nothing.
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.
The browser's `smaller` + `vertical-align: super` grows every line holding a
raised run by ~4px. LibreOffice keeps its raised run within 0.25pt of the plain
line's box (measured off its PDF), and both exporters already write
`style:text-position="super 58%"` — only the screen diverged. The same three
declarations already sit on the footnote anchor. Scoped to the paper, since a
header/footer zone carries the marks and its height is reserved off the page.
Measured: a table LibreOffice fits above the page edge now fits here too,
instead of moving to the next page.
A float only pushes lines that intersect it, so a short block (a heading)
slotted into the clearance gap a prior side float opens above the band.
Word and LibreOffice both start the next paragraph below the band; a
page-break spacer and the partner block of a wrapAlign pair are exempt.
The always-on absolutely-positioned ¶ pseudo made Chromium give up
balancing the multicol: every block stacked into column 1, while Word
and LibreOffice balance the section end. Static inside .columns-node
(zero width, line breaking unchanged); past a trailing BR the mark is
dropped there so an empty paragraph stays one line.
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.
An inline atom drawn gray as ‹label›: a click selects the whole field,
typing replaces it, Tab/Shift-Tab jump between fields. Exports to ODF
<text:placeholder> (PLH sentinel U+E022) and a DOCX w:sdt content
control tagged edentext-placeholder; both importers read it back, the
export-minted gray stripped. Covered in roundtrip Leg 31 + fuzzDoc.
public/ is copied verbatim into the build, src/assets/ is not - so the fonts
were deployed without the license texts that OFL-1.1 and Bitstream Vera require
to travel with them. Moving the texts to public/font-licenses/ fixes that with
no build step. The notices covered only Liberation and missed five bundled
dependencies; the commercial license now states what it cannot relicense, the
copyleft German dictionary and thesaurus above all.
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.
Under the ribbon it takes the same --w-* remap .ribbon gives its pickers: the
app's dark neutrals are bluer than Word's, so the two ends of the window did
not match. Classic keeps the themed set. --color-primary is the brand slate
now, so both chromes share one accent.
--w-accent is the logo's slate instead of Word's blue (5.1:1 on the chrome,
carries white), and the clay marks the contextual tabs — the pair meets where
those sit beside the normal ones. Both defined once from favicon.svg; the
label tone is darkened, the clay itself only 3.3:1 on white.
Ruby, as both products' phonetic guide writes it: one element holding a
base and its reading, so the editor keeps it as one inline atom and the
browser sets it as a real <ruby>.
ODF gets <text:ruby> plus a minted ruby-family style (centred, above —
probed: LibreOffice writes that style back unchanged); Word a <w:ruby> run
from a post-pack pass, the package having none. Both legs verified through
a LibreOffice re-save, our .docx to .odt included.
LibreOffice's Word Completion, its defaults included: words from eight
letters up are collected as they are finished, and the first three
letters offer the rest. The offer is a widget decoration after the caret,
so it is outside the document until Enter takes it — nothing to undo when
it is not taken.
Only while typing: a bare caret move drops the offer, or an Enter meant to
split the paragraph would complete a word instead. The settings share the
AutoCorrect dialog, as they share LibreOffice's.
Every recorded change in document order beside the comments pane: author,
date, the text, accept or reject in place. A change split by a paragraph
boundary is one row, so acceptRevision/rejectRevision take an id. The
author colour is a decoration, since a mark cannot know the document's
other authors; it nests inside the mark's span and carries the under/
strikethrough with it. shortcutHint no longer throws on an id nothing
binds, which heading 7-10 had just made reachable.
HTML stops at h6, so 7-10 render as unknown elements editor.css makes
blocks; their built-in styles continue level 6 at 12pt, since LibreOffice
writes these styles with no properties and resolves them from its own
pool. Both importers read a two-digit level again (the style-name regexes
stopped at one digit). Verified through a LibreOffice re-save of both
formats and in the live editor.
LibreOffice's Format > Paragraph > Text Flow checkbox. Only "off"
travels (Word has no per-paragraph "on") and only under a document that
hyphenates, or it would say what is already true. ODF writes
fo:hyphenate="false" into the paragraph's text properties, DOCX gains
w:suppressAutoHyphens through a post-pack pass — the docx package
exposes no option for it. Both survive a LibreOffice re-save.
Both were selectable in the dialog and changed nothing — they only rode the
file formats, so an imported document numbered and placed its notes wrong.
noteLabels now counts within a bucket (class, chapter, or the page pageBreaks
publishes through setNoteAnchorPages); a collected footnote leaves position:
absolute and opens its own page, as LibreOffice does. Counting and position
move to the footnote tab, the only place LibreOffice offers them.
The separator's own alignment moves the line alone — probed, notes stay left.
Two faults on one picture. A block after a float keeps its box over
the float — only its lines move — so the caption on top swallowed
every click meant for the picture; the frame is lifted above the
in-flow boxes. And a caption can only sit under a side-wrapped frame
if it is boxed to it, so its span in the column is measured and
becomes the caption's indent, which also drops it clear of the float.
Measured at 100% and 150%: caption under the picture, its width, in
all four wrap modes.
Two endpoints rather than a box: no text, no fill, and the diagonal of
the frame with `flipV` picking which one. The three kinds share their
preset names, since the heads a file declares are what tell them apart.
ODF gives a line its own element and its heads a named marker, which
needs the draw: prefix declared in styles.xml — undeclared, the file
does not parse at all. Word keeps the frame and flips it.
The formula rides the cell, as ODF writes it; Word's field syntax is what
is stored, since it is the wider language. `ooow:` in the ODF attribute
value is a namespace prefix — undeclared, LibreOffice reads it as part of
the formula and prints "Expression is faulty".
Sort takes one key and detects the type per cell where both dialogs make
you pick. Number recognition is off by default, as it is in LibreOffice,
and a formula parses a cell's text either way — exactly as there.
The page grid was one repeating cycle, so every page had to be the same
size. It is now a table of height runs the placement pass grows as each
section's first page becomes known, and the sheets are one box per page
instead of a repeating gradient — .paper reserves the widest section's
paper, a narrower one takes the difference as a right inset.
Layout ▸ Orientation offers "this section"; the size stays document-wide
in the ribbon but round-trips per section from a file.
The citation is an inline atom holding the whole record, which is what ODF
writes on text:bibliography-mark — so no database travels beside the file.
The list is a new index family: one row per source, in document order and
without page numbers, as LibreOffice prints one.
DOCX cites by tag and keeps the sources in a custom-XML part the docx
package knows nothing about, so the post-pack pass mints the part, its
properties, both relationships and the content type itself.
References ▸ Index entry marks a place with the term the index should
list — under a key of its own where it belongs elsewhere — and the Index
in the same menu lists each term once, sorted case-insensitively, with
every page it was marked on.
Both formats write a place, not a range, so the entry is an inline atom:
ODF text:alphabetical-index-mark plus text:alphabetical-index, Word XE
plus INDEX. LibreOffice reads our file back unchanged. The bibliography,
the other half of that gap, is still open.
Twelve presets beside the three rectangular ones. Each outline is one
polygon in utils/shapes.ts, given once: the node view draws it as an SVG
path, the ODF export scales the same points into draw:enhanced-path, and
Word gets the preset's name and draws its own geometry.
A gallery in the box toolbar and the ribbon renders its tiles from that
same table, so a new shape needs no icon. Verified through LibreOffice
from both formats; a preset we can't draw still imports as a warning.
Two marks carry a revision with its author and date: an insertion is
marked text, a deletion is text kept and struck through. Consecutive
typing joins one change; accept/reject work at the cursor or on all.
ODF splits the pair — text:change-start/-end around an insertion, a
text:change where a deletion was, its text in the tracked-changes
registry. DOCX uses w:ins/w:del with w:delText. Both round-trip, and
accepting every change gives the document an unrecorded edit would.
The comment is a mark carrying its own author, date, body and resolved
flag — the bookmark pattern, so no second store and no schema node. The
pane lists them in document order and jumps to the text each marks.
ODF gets office:annotation + office:annotation-end and LibreOffice's
loext:resolved, DOCX the range pair plus word/comments.xml; a point
comment, which LibreOffice writes without a range, attaches to the run
before it. Ctrl+M no longer strips a comment, a bookmark or a link.
LibreOffice's style pool, probed: Heading 6 is 12pt bold italic and
Heading 4 italic too. MAX_HEADING_LEVEL drives the extension registry,
the shortcut plugin, the TOC depth and both importers' yardstick, so
only the constant table and the CSS selector lists had to grow.
Bookmarks/cross-references move to Implemented — they already are.
Neither word processor passes it into a cell — LibreOffice puts cell text in
its Table Contents style, Word's table styles carry w:spacing after=0 — so the
space filled the cell and vertical alignment had no slack left to move the text
in, which read as the alignment being ignored. The space above is LibreOffice's
alone, so only the add model zeroes that too. Both exporters write the zeros
onto the paragraph, and only when the default style has spacing at all.
The band was a round 108px while its tallest control measured 65, so each tab
carried a strip of empty chrome above its buttons. Padding, gaps and the caret
slot come in, the band is cut to what the controls actually need, and the style
gallery stops short of the group label it was sitting on: 144px of chrome to
118px. Line-heights are pinned in px — as ratios they hand the band's height to
whatever font resolves, and the group footers hang out of it.
The rule that drops the space above it never applied to a Word document:
:is(p, h1, …, .toc) takes the class specificity of .toc, so the later
spacing-model rule tied at (0,4,0) and won on order — and the heading
opening a two-column section sat 3.5mm below the column beside it.
Zeroing the property both spacing models read settles it, and beats the
block's own inline value as a margin would not. Probed: LibreOffice
starts both columns level; a two-column page now matches it 45 lines
deep, where it diverged at line 8.
The marker moves from a CSS ::before to a widget decoration: generated
content is no text node, so it reached neither the PDF nor a measurement.
The note also carries the paragraph style its file names, so font, size and
colour are the document's; only the hanging indent stays the editor's,
because the style model has no first-line half to pair with the margin.
Adds a unit test for the numbering and the settings, plus the architecture
doc and the two open parity findings.
Numbering format, start value, restart, position, prefix/suffix and the two
styles per class, plus the separator's length, thickness, spacing, alignment
and colour. The separator rides :root custom properties, so editor.css draws
the line and pageBreaks.ts reserves its band from the same values. A settings
change is no document change, so it carries a resync meta — without it the
numbering kept the format it was typed under.
The placement loop moves into placeLeaves(), which takes a per-page note
reservation off each contentEnd; a bounded fixed point re-runs it until the
reservation and the pages its own anchors land on agree. Each break now
carries the leaf offset it applies from, so an anchor below a line split
follows its half of the paragraph. Endnotes stay in flow and open their own
page, as LibreOffice collects them.
The anchor is an inline atom, the note text a block in the one noteSection
at the document end; a sync plugin keeps notes in anchor order, renumbers
them per class and drops the ones whose anchor is gone. Numbering, indent,
size and separator defaults are LibreOffice's, read out of a document it
saved. Endnotes still render in flow at the document end — lifting a
footnote to the foot of its page is the next step.
A pagination pass measures the DOM the last one changed, so a fresh
document searched for its layout in public — 12 of them over 550ms on a
two-column file, a phantom third page among them. Two real causes: the
flow's overflow test had no headroom, so it read its own last answer
(880px fits undecorated, 913px overflows once the decoration pins the
column height), and a split dropped the height decorations without
clearing their cache key. The rest is inherent to measuring rendered
DOM, so the page stays hidden until its layout repeats: one visible
layout instead of 12, and 21-139ms where there are no columns.
Rows & Columns follows Word: four big buttons carrying a 28px glyph and a
two-line label, with the three deletions folded into one Entfernen dropdown
beside them so the group keeps its width.
Two lines cost the band 12px (--w-ribbon-h 96 -> 108). The labels size to
min-content, not max-width, which a wrapped box ignores; and the inserts drop
the reserved caret slot, without which the group's foot label sits 8px below
every other group's.
Brings the ribbon chrome, its tabs and controls, the Paragraph/Tabs dialogs
and the shared selection reader over from word_ui. No file overlap with
main's cover-graphic fix, so the merge is clean.
Ten of the fifteen caret buttons ran the same toggleMenu from both halves,
so they were split for nothing. They are single buttons now, with the caret
under the label rather than beside it — 13px narrower each, and Word's own
Paste button.
The tint takes the whole button, label included: a row mixes buttons whose
label is inside the button with pickers whose caption is a sibling, so half
of them lit up under the words and half did not. `captionClicks` gives the
caption the click to match, and the picker's trigger takes the icon box's
34px so glyphs and words land on one line.
Word's dark palette on the same metrics: Fluent's dark neutrals, chrome
#1f1f1f, and the accent lightened because #185abd on a dark chrome is
unreadable. AllBlack goes on to Word's Black theme. The lightened accent
cannot carry white text, so the File pill and the pickers' --color-primary
take a second, filled accent — identical to the first in light mode.
Every reused picker anchors its panel to its own trigger, so the band clipped
it: the table grid showed one row of eight. `pinPanels`, one action on the
band, pins whatever panel mounts inside it, and panels now drop below the whole
band instead of over the controls under them.
Their triggers also kept the classic toolbar's compact box, so Table, Symbol
and Date & time were half the size of the buttons beside them. `.rb-captioned`
moves to global.css, replacing four copies, and gives the trigger the big
button's 34px box, a 28px glyph and the ribbon's own hover and open tints.
The shared pickers frame their trigger for the classic toolbar's island; in a
ribbon row of borderless buttons that reads as a different control, and at
27-28px it broke the row's line. Every trigger is 30px there now. Redrew the
change-case and highlighter glyphs, which were malformed and off-centre.
The dialog sized each row on its own, so a long label wrapped and "pt" vs "cm"
shifted the field beside it - fixed unit width, no wrap, one 2x3 grid.
Two compounding bugs on a title/back-page background image:
- its host paragraph picks up position:relative from the line-height
rule, becoming the frame's containing block instead of the page and
offsetting it by a full page margin — now forced back to static.
- the frame always painted behind text (z-index -1); a graphic that
declares ODF's style:run-through="foreground" now paints in front,
as LibreOffice draws it, via a new inFront attr round-tripped through
ODF export/import.
Confirmed against LibreOffice's own render: the duplicated, ~2cm
displaced cover graphic now matches exactly.
Clipboard, Font, Paragraph, a style gallery of live tiles, and Find/Replace —
which had no button in either chrome before. So did change case, underline and
strikethrough line styles: the engine has carried them all along.
Two things the fixed-height band forced. Its own overflow clips a dropdown, so
a menu leaves the flow and pins itself under its trigger. And with one shared
open-menu id, each wrapper must name the menu it owns, or every sibling closes
it on mousedown and the click on a row never lands.
