Extrude & Bevel (Classic) ships, so the remaining-work lists in
effects-parity.md, gaps.md (G3), target-app-parity.md and three-d.md
name Revolve (Classic), Rotate (Classic) and Map Art instead of all of
3D Classic.
A manifest may list `permissions` (doc.read, doc.write, state,
effect.render, export.write) and an `api` level. doc.read, doc.write
and state follow the capability model proposed in
storytold/photocraft#662; the other names are VectorCraft's own. An
unknown, reserved, duplicate or wrong-kind name is refused by name. A
manifest without the key gets the permissions its kind implies and
installs as before.
- Install Plug-in... and File > Open show the name, id, version, file
SHA-256 and each permission in plain words, with control and
bidirectional characters escaped and each string cut to 64
characters. OK installs the module only if it still has the SHA-256
shown; Cancel installs nothing. The heavy-budget prompt and the
status line show the escaped name too, and OK keeps the `replace` it
was given.
- `plugin.install` needs `grant` listing every permission, and
`plugin.inspect` reports `needsApproval`. `hash` pins the module:
one with another SHA-256 is refused. The grant is kept with the
module's hash in the store's `grants.json`, and only that store's
grants count while it is attached; the same set does not ask again,
more permissions do, and `plugin.remove` forgets it.
- The Additional Plug-ins Folder and `plugin.reload` install only
plug-ins the attached store has granted and report the others as
needing approval. At startup the store skips an ungranted plug-in.
- A filter run without doc.read is given no objects; without state it
neither reads nor writes `documentData`; without doc.write an output
that changes the document is refused and the document is unchanged.

Effect > 3D and Materials > 3D (Classic) > Extrude & Bevel (Classic)... applies
`threeD.classicExtrude`, a live effect built on the Extrude & Bevel solid. It
takes Extrude Depth, Cap, a bevel with Height and Bevel Extent In or Out, the
Position presets, rotation and Perspective, and draws the faces with the
Wireframe, No Shading, Diffuse or Plastic surface: one to ten lights, Ambient
Light, Highlight Intensity and Size, Blend Steps, a Black, Custom or no Shading
Color, and Draw Hidden Faces. Invalid parameters are refused with an error.
vectorcraft-js gains a Realm that runs ECMAScript 5.1 scripts. The parsed
script compiles to stack-machine bytecode, a verifier checks every jump
target, handler, constant index and stack depth before the code runs, and
the interpreter keeps JavaScript calls on its own frame stack. Closures,
this, arguments, with, direct and indirect eval, new Function,
try/catch/finally, labeled break and continue, and for-in in insertion
order follow sections 10 to 14 of ECMA-262 5.1. Variable references are
resolved before the right-hand side of an assignment runs (11.13).
Objects and environments live in an arena with a mark-and-sweep
collector and index handles. Built-ins are limited to Object and
Object.prototype's basic methods, Function with call and apply, eval
and the error constructors.
Every run is bounded by fuel, heap bytes, frames, nested host calls and
an interrupt flag another thread can set, with smaller defaults in the
wasm build. A run that reaches a limit ends with a limit error that a
script's try cannot catch. Source passed to eval and Function counts
against Options::max_source_units.
cargo xtask test262 also runs the suite's ES5 test/language tests that
need only these built-ins and prints their counts apart from the parse
counts. Nothing in the app calls the interpreter yet.
A stroke-only path or compound path that uses the even-odd rule keeps
its live effects in the editing copy; the art-style writer leaves out
only paths that fill by the even-odd rule.
The editing copy of a PDF-compatible .ai left out the Graphic Styles
panel's styles and objects' links to them, with a warning. They are now
written as art styles:
- The panel's styles come first in %AI9_BeginArtStyles and are listed in
its order in %AI9_BeginArtStyleList after the palette, with their
fills, strokes, transparency and effects. Fills and strokes may have
transparency and effects of their own, and a style may also hold Warp,
Transform, Free Distort, Pucker & Bloat, Twist, Zig Zag or Gaussian
Blur. A style of an object's own holds the same effects as before.
- A path, compound path or group linked to a graphic style names it when
it has the style's appearance, the style is written, and the reader
reads that style on that object. Objects linked
to a new document's styles keep their link: the panel is written for
them too.
- The writer reads each style back with the reader before it writes
it. A style with gradient or pattern fills, with anything the
reader does not read back, with a name another style has, with a name
over 1,024 bytes or past 4,096 styles is left out with a warning. Other
links are left out with a warning, and a panel with no style written
warns that it opens with a new document's styles. No graphic style is
written on a large canvas, with a warning.
Graphic styles:

Tests: the round trip of the panel's styles and of links; each effect a
style can hold; the forms written; the list's limits; duplicate names; an
empty panel; links left out; a style's opacity at the written precision;
a large canvas; Twist and Transform on an object with no link; a link
to a style whose Transform moves the outline, with and without an
opacity mask; the
reader's reading of warp numbers; fuzz cases for damaged written styles.
Docs: docs/file-format-parity.md.
The editing copy keeps live effects on qualifying objects only when the art-style writer supports their appearance and effects. README, ROADMAP and the progress docs now say so and link to docs/file-format-parity.md for the limits.
The .ai editing copy writes an art style for paths, compound paths and groups with live effects only when they have at most a fill and a stroke, fill by the non-zero rule, and are not on a large canvas. README, ROADMAP, gaps, roadmap and target-app-parity say so.
The fallback for objects that can't use an art style keeps their vector
art with geometry effects applied and leaves out their other effects,
such as Drop Shadow, the glows and Feather. README, ROADMAP, gaps,
roadmap and target-app-parity no longer say every live effect is left
out, and target-app-parity lists the round-trip tests.
Paint-only harakat runs stay inside one shaping cluster so letters keep
their joining forms and marks their attachment. When a character-level
shaping pass matches the monotone glyphs, a glyph may take a later
in-cluster character's run only if GDEF classifies it as a mark (class 3)
and that character is a harakat; otherwise ownership stays at the cluster
start. Conservative: a mark may miss its colour; a base letter must never
take a mark's. Fonts without GDEF and AAT faces fall back the same way.
Insert Kashidas tatweels take the base letter's paint, not a trailing
mark's. Private harakat module; type-parity, target-app-parity and roadmap
M7 evidence updated (scores unchanged). Tests cover paint_only / ranges /
own_chars (wide mark, equal advance, multi-component, single-glyph
ligature, review counterexample), colour, hide, repeated glyph ids,
kashida, forced mark-last emit_kashida, and installed fonts.
A new standalone crate, vectorcraft-apischema, describes a command's
parameters: type (number with range and unit, integer, boolean, string,
enum, id, id list, color, point, object, array), whether each is
required, the default of an omitted value, whether null counts as
omitted, the API levels it was added and deprecated at, and the lenient,
cost and writes fields. It validates a params object and names the
parameter of the first problem, writes the params text, writes the
schema in the shape of a JSON Schema 2020-12 object schema, and hashes a
set of schemas.
CommandSpec gains an optional schema (both builders: the cmd! macro and
the text style specs). Session::execute checks the params of a command
that has one before anything else, refusing a value of the wrong type,
out of range or not in its list, a missing parameter or an unknown key
with an error naming the parameter, and fills in defaults; the journal
keeps the params as given. engine.commands lists each schema.
The six commands in cmd/views.rs have schemas, and their params text is
the text the schema writes. schemas::API_VERSION is 1, and a test fails
when a schema changes without a new row in SCHEMA_HASHES.
Docs: docs/mcp.md (Parameter schemas), docs/target-app-parity.md.
New crate vectorcraft-js reads ECMAScript 5.1 source into a syntax tree
with source positions: a UTF-16 lexer (line and column tracking, automatic
semicolon insertion, the regexp and division goals), preprocessor lines
read as directive tokens, a recursive-descent parser to an arena tree, and
the ES5 early errors, strict mode included. Nesting deeper than
Options::max_depth (200 by default) gives a SyntaxError with its line and
column rather than overflowing the stack. Nothing runs scripts yet.
cargo xtask test262 downloads test262 at a pinned commit, checks its
SHA-256, unpacks it into the gitignored corpus/ folder and runs the ES5
syntax tests. A differential test in the engine compares the lexer with
scriptcheck on line counts, directives and unterminated literals.
The contour passes of the two-path boolean operations, Offset Path and
the many-shape boolean (`boolean_n`, used by compound shapes and
Intertwine) built a flag for every input shape for each winding they
tested. They now test the list of inputs that cover the face, ascending,
refilled in one buffer per pass, so a test costs the size of the cover
rather than the number of shapes. `boolean_n` and `try_boolean_n` take
that list; the compound shape and Intertwine tests read it directly.
The contours, their order and the output are the same: a new test
compares every pass's test with the flag form on overlapping, nested,
touching and apart squares and on 72 overlapping squares, and another
checks that a pass over 100 squares apart hands its test one input at
most.
The editing copy of a PDF-compatible .ai wrote an object's live effects
as their result (geometry effects) or left them out (the others).
Objects with effects the .ai reader reads are now written as art styles:
- An object is written as its drawn look (a group of its vector art as
its geometry effects leave it, without shadows, glows or feathers,
with the object's transparency after it), then the object itself on
%_ lines (its points painted with nothing, or with its gradient fill
placed on the outline it draws; a group with its members), its name
and opacity mask, and
1 (style) XW naming its style.
- Styles are written in a non-printing block after the symbols, in
%AI9_BeginArtStyles: a chain of the stack of fills and strokes (with
the contents where the appearance puts them), the effects and the
object's transparency. Objects of the same appearance share a style.
- The effects written are the ones the reader reads on objects, with
their settings in the units it reads them in: Drop Shadow, Inner Glow,
Outer Glow, Feather, Round Corners, Scribble, Convert to Shape, Offset
Path, Outline Object, Outline Stroke and Pathfinder > Add.
- Each style is read back before it is written, by a new reader
function, read_art_style, which runs the reader's style parser and its
reading of a graphic style with the object's own gradient. An object
whose style reads back differently (several fills or strokes, fills
or strokes with transparency or effects of their own, pattern fills,
other effects), a filled object that fills by the even-odd rule (a
style's fill fills by the non-zero rule), a group whose effects change
its members' outlines while a member is written on another outline
(strokes as filled outlines, pattern fills as tiles, gradients that
fit their object), or one in a container whose own
effects change its members, is written as its drawn look with the
warning, and a style that is not written leaves no gradient
definition behind. Graphic styles and links to them are left out with
a warning. No art style is written on a large canvas.
Appearance attributes:
https://helpx.adobe.com/illustrator/using/appearance-attributes.html
Tests: the round trip of objects with each effect, a gradient fill, a
group with transparency and a mask, Pathfinder > Add and a hidden
effect; the same bytes on a second write; the forms written; the
objects the reader would not read; a large canvas; the warning for
graphic styles; filled even-odd objects; a gradient placed on the
outline Offset Path draws; a style that is not written; effects in a
pattern a drawn look uses; the reader's check of a style; fuzz cases
for damaged written styles.
Docs: docs/file-format-parity.md.
A paragraph that ends in a soft return ends with the empty line after it,
so the line the soft return ends is justified like any other; it was taken
for the paragraph's last line and left aligned.
Key 30 of a paragraph's attributes holds its tab stops: each its position
(key 0) and alignment (key 1: 0 left, 1 center, 2 right, 3 decimal).
They were not read, so tabs fell on the default stops. At most 1,024 are
read a paragraph and 2^20 copied into a story's paragraphs, past which the
default stops apply with a warning. The fuzz test feeds hostile paragraph
attributes: alignments, auto leading, hyphenation options and tab stops.
In right-aligned area type, the text before a line's last tab sits at its
stops, measured from the left edge, and the text after it (none when the
tab ends the line) against the right edge. The line was laid out from the
left and aligned as a whole, which moved its start off the left edge and
its tabs' text off their stops. Illustrator's own layout in a user's .ai
sets its price lists so. Centred and justified lines are aligned as a
whole as before.
The line names trapping, Intertwine and the Pathfinder effects next to
Divide, Hard Mix, Soft Mix, Shape Builder and Flatten Transparency, and
gives six alternating runs of each build of Divide on 3,000 overlapping
rectangles, timed on this branch's final code.
Finding the distinct regions of an arrangement built a flag for every
input shape at each edge and kept them in a sorted set, so it cost edges
times shapes in time and memory. Each coverage is now the sorted list of
the shapes that cover it, deduplicated in a hash set and sorted into the
order the flag masks had, so regions, their order and the output of
Divide, Hard Mix, Soft Mix, Shape Builder and the flattener are the same.
The face lookup and Pathfinder merging take the same lists.
Tests compare the lists and the regions with the flag masks for
overlapping, nested, touching and disjoint shapes and for 72 shapes.
The editing copy of a PDF-compatible .ai wrote every symbol instance as
its art. Symbols are now written as symbols, in the form the .ai reader
reads them:
- Every symbol is defined in the setup, in a non-printing block after the
patterns: %AI14_BeginSymbol, its name, its art in the symbol's own
space, its registration point as AI13PatternRegistrationType and
%AI10_EndSymbol, each after the symbols its art uses. The nine points
are numbered 1 to 9 row by row from the top left, in the order the
scripting reference lists them. A definition is written the same
wherever its first instance lies. The symbol list after the palette
keeps the Symbols panel's order. A hidden root of a symbol's art is
written shown, as the canvas draws it.
- Each instance is a /SymbolInstance with its symbol's name and the matrix
that places the art (to ten decimals), followed by its name, opacity
mask, opacity and blending mode as a group's. In a symbol's art, the
matrices of instances, gradients and images are written in the
canvas's space about the canvas point of the ruler origin.
- Pattern fills in a symbol's art are written as their tiles cut to the
shape. A symbol whose definition holds such tiles, from its own
objects, a brushed stroke's brush art, a live object, an opacity mask,
a nested symbol or an inline graphic, has its instances written as
their art.
- Instances with a fill, appearance changes, isolation, knockout or
knockout shape of their own, instances of symbols with 9-slice guides
or pattern paint, instances in pattern tiles or in art cut to a
clipping object, instances scaled almost flat, instances that turn,
mirror or scale symbols holding type, live objects, instances written
as their art, shapes with rounded live corners or strokes written as
outlines or brush art (the canvas works these out again where the
instance puts them), instances that scale their symbol more than 100
times, nested instances included (numbers are written to four
decimals), and instances on the layers of a large canvas are written
as their art (the symbols are still defined). Symbols past the 4,096
the reader keeps are left out and their instances written as art; an
instance of a symbol the document doesn't have is an empty group.
9-slice guides, export types and the dynamic type are left out, and
linked images and type in a symbol's art are embedded and written as
outlines. Each comes with a warning.
The writer takes the reader's limit of 4,096 definitions (MAX_SYMBOLS)
and its symbol_art_member check, which now are pub(crate).
The editingData option's description lists what the copy now holds,
type written as text included.
Symbols and their instances:

Tests: the round trip of symbols, nested symbols and instances in every
state, symbols whose art is a group with a state of its own, images and
gradients in a symbol's art, every registration point, symbol names with
special characters, duplicate and missing symbols, a symbol first used
deep in opacity masks, symbols past the reader's count (one found only
while its holder's art is written included), a large canvas, symbols
with pattern fills (directly, nested, in an opacity mask, through an
inline graphic and through a brushed stroke), scaled instances of
symbols with an outside stroke, rounded live corners, type, a blend, a
tiny or thin object, an ellipse or an instance of a symbol with 9-slice
guides, a symbol whose root is hidden, instance matrices from a fixed
seed, a second write of what is read back giving the same bytes, the
forms written, the instances written as art and the options reported.
Docs: docs/file-format-parity.md, README.md, ROADMAP.md, docs/gaps.md,
docs/roadmap.md and docs/target-app-parity.md describe the editing copy
a saved .ai holds.
- Auto leading stays auto: each line takes the paragraph's share (key 7)
of the largest type on it. The leading was the first two lines'
distance for every line, so 10 pt lines under a 15 pt heading came in
18 pt apart.
- The paragraph's hyphenation options (keys 10 to 15) are read.
- Area type of one frame whose last lines the file sets, but which don't
fit here (the fallback font, or a descent past the frame's bottom),
gets a frame taller from its bottom (vectorcraft_text::fit_source_lines),
with a warning.
A user's .ai whose type differed from its page by 6.6%, so that it opened
from its PDF part with each line its own text object, now opens from its
layers.
In Justify Left, Center or Right, only the paragraph's last line keeps its
alignment; a line that a soft return (U+2028) ends is spread to the frame's
edges like any wrapped line. Illustrator's own layout in a user's .ai sets
such lines justified, and VectorCraft left them ragged.
A .ai or EPS whose editing data defines symbols but has no layers came
in as its PDF part or page without symbols, and Other Library in the
Symbols panel listed none. Such a file, and a file read as its PDF part
or page because its layers can't be used, now gets the symbols its
editing data defines before its first layer, as a file read from its
layers does: File > Open shows them in the Symbols panel in the order
of the symbol list, and Other Library lists them in a library panel.
- Each symbol keeps its registration point. A symbol that holds an
instance of a symbol the file doesn't define is left out, and an
object linked to a listed graphic style keeps the link.
- The symbols' art takes ids of the document, the art of opacity masks
in it included, and the images it shows come with it. Instances
drawn too deep are removed with the usual note.
- The global and spot colors the art is linked to come in as swatches.
A color whose name another swatch has takes that swatch's place when
it is a default swatch of a file without a palette; otherwise it
comes in under a free variant of the name ("Ink 2"), which the art
then names.
- Symbol art keeps the editing data's units, as in a file read from its
layers, so in a file in larger units its linked graphic styles are
drawn at the scaled size and the symbol art is not.
- The art of the patterns a palette or brush brings into a file read as
its PDF part or page now also takes new ids for its opacity masks.
Part of #3349
An object opacity or blend mode set on a path directly in a graph series, and
the blend mode of its topmost visible fill or stroke, were lost when the graph
was drawn again. The graph now stores them per series next to the row opacity
it already stores, and puts them on every path directly in the series when it
draws the series again.
- transparency.set and object.setProps store the object's opacity and blend
mode. A value the mark already has still replaces the value another mark of
the series stored.
- appearance.clear, appearance.transfer, appearance.copyFrom with Transparency
picked up, graphicStyle.apply without add and graphicStyle.redefine store
the object's opacity and blend mode they leave on the mark.
- The other Appearance and style commands store them when they change them
on a mark.
- Every command that stores the opacity of the topmost visible fill or stroke
also stores its blend mode. A Filled Lines band's outline takes the stored
stroke opacity and blend mode and keeps its black 0.25 pt stroke.
- An opacity and blend mode are stored as a pair from the edited mark:
setting only the opacity of one mark also stores that mark's blend mode.
- A graph design's copy in a series keeps its own values.
Docs: docs/mcp.md, docs/target-app-parity.md.
What a data source procedure allocates stays counted: only the sample planes,
the decoder's copies of the strings a procedure returns, and the split buffers
of an interleaved masked image stop counting once the image is decoded.
Applying a graphic style, Redefine Graphic Style, Default Fill and Stroke
and Swap Fill and Stroke on a path in a graph series changed the path
but not the paint the graph stores for the series. When the graph was
drawn again, the series went back to its earlier paint.
These commands now store the mark's topmost visible fill and stroke on
the graph, in the same undo step as the command:
- graphicStyle.apply stores the paint, weight and opacity of both kinds
of row. With `add` it stores only the kinds of row that are visible
in the style.
- graphicStyle.redefine stores the paint, weight and opacity of the
marks still linked to the style.
- paint.default stores the white fill and the 1 pt black stroke, both
opaque.
- paint.swap stores the swapped paints and the stroke weight and keeps
the stored opacity. It swaps the topmost rows even when they are
hidden, and a hidden row it swaps is not stored.
The rule for each kind of mark is the one docs/mcp.md gives for the
Appearance commands. docs/mcp.md also says what the graph does not
store from a graphic style and that a series group given to a graphic
style command is not stored. The params text, docs/mcp.md and the
Graphs line in docs/target-app-parity.md list the commands.
