Space held while dragging out a new anchor already moved it, handles and
all, but the closing drag skipped it, so the closing anchor could not be
repositioned. The closing drag now moves the first anchor by as far as the
pointer moves while Space is held, its handles with it, and the drag
shapes the handles round the new place once Space is released.
path.close takes `at: [x, y]`, which moves the first anchor, its handles
with it, before `in` and `out` are placed. docs/mcp.md and the Pen line
in docs/target-app-parity.md describe it.
Closing a path by dragging on its first anchor made that anchor smooth
with symmetric handles, so the first segment bent along with the closing
one. The drag now sets the first anchor's incoming handle to the mirror
of the pointer. Its outgoing handle stays where it is on a corner, so
the first segment keeps its shape, and on a smooth anchor it turns to
stay in line at its own length. Alt makes the anchor a corner and leaves
the outgoing handle where it was when Alt went down. A click on the
first anchor closes the path with the incoming handle retracted and the
anchor a corner, so the closing segment comes in straight.
The Smart Pen's closing drag follows the same rule.
path.close's `in` now places the handle as path.setHandle does, and a
new `out` param places the outgoing handle and makes the anchor a
corner.
Commands that need an object id read it with `id_param`, which returns
None for a value that is not a non-negative integer, so `{"id": "5"}` or
`{"id": -1}` was refused with "missing id". They now read it with
`object_param`, which refuses such a value with "`id` must be a whole
number", naming the key. This covers `document.node`, the `path.*` anchor
and handle commands, the `text.*` range and path commands, the mesh,
envelope and slice point commands, `layer.target`, `layer.move`,
`node.move`, `select.magicWand`, and the `source`, `target`, `group` and
`path` keys of `appearance.transfer`, `appearance.copyFrom`, the
`livePaint.*` commands and `text.createInPath`.
The optional `group` of `livePaint.fill` and `parent` of `node.move` are
refused the same way when given. Before, a malformed `parent` moved the
object to the top level and a malformed `group` fell back to the
selection.
Ruler guides were a list kept beside the layers. Each guide is now an
object of its layer or sublayer, always directly in it and above the
layer's art. These behave as on main:
- Guides draw on screen only. Exports (SVG, PDF, PNG, PSD), Fit All,
Select All, the art bounds, clicks and marquees, and a layer's
Pathfinder and Transform effects leave them out. The Layers panel
lists them as guide rows of their layer, the highest guide.list
index first.
- Deleting a layer deletes its guides, and merging layers keeps their
guides in the merged layer.
- The guide commands number guides as guide.list does, in the order
they were made.
New: each guide takes an id from the document's object ids. An object
command given a guide's id fails with an error, and node.move cannot
put a guide into a group or out of its layers. A guide made while an
opacity mask, a symbol or a pattern is edited moves to the top
visible, unlocked layer when editing ends.
File format: native files still save the guides in the document's
guides list, in every file version, so older builds read them. Each
entry may now also carry the guide's id, name, locked and hidden
flags; older builds ignore those fields. Opening a file puts each
saved guide on its layer (on the top visible, unlocked layer when the
file names none or a layer it does not have), and each saved guide
counts against the object limit for opening a file. A ruler guide node
that a file holds below a layer's art moves up to the layer's guides,
and one anywhere else (in a group or another object, beside the
layers, or in a symbol) is removed. Ruler guides read from an .ai file
become guide objects on the layer they were on, numbered in the order
the file lists them.
path.reshape refused focal with radius only when focal named an anchor.
Since an empty focal list chooses the focal-point rule, a call with
"focal": [] and a radius was accepted and used the radius falloff,
although the params text and docs/mcp.md say the two cannot be used
together. Any focal other than null now goes with radius as an error.
A selected segment that path.insertAnchor splits stays selected as its
two halves. The new anchor is the end both halves share, so it moves
with them, and Delete cuts both halves. docs/mcp.md and the comment on
renumber_after_insert called it a direct-selected anchor; they now
describe it as an end of the halves that moves with them.
Before the Reshape tool had focal points it sent path.reshape without
focal or radius, and the command stretched an open path from the grabbed
point to its ends whatever the selection, and moved the anchors of a
closed path within half the diagonal of its bounding box with a
falloff. Such a step, in a saved action or a script, now moved a closed
path whole. A step without focal (or with focal null) and without
radius now plays by that earlier rule. The Reshape tool always sends
focal, an empty list included, so its drags keep the focal-point rule.
path.insertAnchor (the Add Anchor Point tool, the Pen's Auto Add, the
Smart Pen's Alt-click on a segment and Alt-click with the Scissors)
added the anchor without changing the selection, so the direct-selected
anchors and selected segments after it on the subpath kept their old
numbers and the selection shifted onto the next points along. It now
renumbers them with renumber_after_insert, the helper path.reshape
uses. A selected segment that the new anchor splits stays selected as
its two halves, and the new anchor is direct-selected with them. Undo
restores the path and the selection in one step.
Docs: params text, docs/mcp.md, docs/target-app-parity.md.
A click with the Reshape tool on an anchor of a selected path makes it
the focal point, and a click on a segment adds an anchor there that
becomes the focal point. Shift-click adds an anchor or a point on a
segment to the focal points, or removes an anchor that is one already.
Each focal point shows a filled anchor square in a larger hollow one.
A drag from a focal point moves all of them; a drag from another point
moves that point alone, and Shift only keeps the drag's angle.
path.reshape takes the other focal points as focal: [[subpath,
anchor]...]. Anchors that are not direct-selected stay in place, and so
do the ends of an open path unless they are focal points. A selected
anchor between two focal points moves by the whole drag, and one
between a focal point and an anchor that stays takes u² (3 - 2u) of
the drag, as before. A closed subpath with every anchor selected moves
whole: a Reshape drag on a fully selected closed path, and path.reshape
without radius on a closed path selected whole or not selected, move
the whole path instead of a local area. With radius, only the grabbed
point's subpath changes, with the falloff as before.
- An anchor added on a segment of a partly selected path is selected,
and the selected anchors and segments after it keep their points.
- A focal pair that names no anchor is refused ("`focal` names [0, 7],
which is not an anchor of the path"), and so is focal with radius.
Docs: docs/mcp.md, docs/target-app-parity.md.
A Reshape drag on an open path moved only the anchors within half the
diagonal of the path's bounding box, measured along the path. On a
zigzag, a wave or a spiral that is one or two anchors, so dragging an
end moved the end and left the rest of the path where it was (#2723).
path.reshape now stretches an open path from the grabbed point to both
ends. The end anchors stay in place. Each anchor between an end and the
grabbed point takes u² (3 - 2u) of the drag, where u is its distance
from that end along the control polygon divided by the grabbed point's
distance from that end. A handle takes the share on the tangent line of
that curve at its anchor, so the handles of a smooth anchor stay in
line with it. A handle that is long beside the span takes a share below
0 or above 1.
This changes the default for every caller that leaves radius out on an
open path. A closed path still moves the anchors within half the
diagonal of its bounding box, and a call that gives radius uses that
radius on open and closed paths.
- A negative radius is refused ("`radius` must be 0 or more"). It gave
anchors beyond the radius a share above 1.
- A drag of no length on an anchor no longer records an undo step.
Docs: docs/mcp.md, docs/target-app-parity.md.
A compound member copied or cut on its own now keeps the compound's
gradient fitted where it was: an unplaced gradient is pinned to the
compound's bounds, measured once per compound.
Clear that deletes every anchor or segment of every member of a compound
path now removes the compound too, as Cut does, instead of leaving an
empty compound in the layer.
The edit.copy and edit.clear descriptions, docs/mcp.md and the progress
line now say that selecting the compound copies it whole, that isolation
mode takes each member as itself, and how a compound of one and Paste in
Front with the copied member still selected behave.
With anchors picked with Direct Selection, Edit > Cut removed only the
segments between them, so the picked anchors stayed in the path. Cut now
removes picked anchors and the segments attached to them from a path or
a compound path's member, as Clear does. Picked segments still lose only
those segments. When a path has picked segments, Copy and Cut leave out
anchors picked on its other contours, as Clear does.
Docs: docs/target-app-parity.md.
The remaining flags under crates/engine/src/cmd that read a boolean with
get(..).and_then(Value::as_bool).unwrap_or(..) now go through switch_or,
so a value such as "false" or 1 is an error instead of the default.
Omitting a flag or giving null keeps the old behavior.
- effect.move: copy
- aligned on the appearance.*, stroke.set, transparency.set and effect.*
commands, checked before any early return
- transparency.viewOpacityMask: on
- view.printTiling: on
- plugin.install: replace and allowHeavy, checked for every plug-in
- edit.clear: guides, and path.deleteAnchors' read of it
- text.create and text.createInPath: vertical (already refused by
check_switches, so their behavior is unchanged)
With anchors and ruler guides selected, Cut deletes the anchors and the
selected guides in one undo step (edit.clear's guides: true reaches the
anchor-deleting path).
Convert to Smooth or Corner on a blend whose spine came from Replace
Spine stored key anchors with the converted spine, so the spine's
points then moved onto the key centers. It now changes only the
spine's handles: the points stay where they are and the keys stay
spread along the spine. Direct Selection's spine conversion and the
other spine edits are unchanged.
With a blend selected, the Contextual Task Bar's Corner and Smooth
buttons failed with "select paths or anchor points", since
`path.convertAnchors` only read paths. They now convert every point of
the blend's spine, as they convert every anchor of a path selected
whole, in one undo step. The key objects stay where they are.
With Direct Selection, the Control bar and the Properties panel now
show their Convert buttons for a selected blend too.
A built-in add-on under Object › Plug-ins › Smart Pen:
- The Smart Pen Tool draws and edits Bézier paths without switching
tools: a click adds the next segment straight or curved (a panel
toggle; Tab flips the segment being placed or the last one), a drag
makes a smooth point (Alt breaks the handle, Shift snaps to 45°, Space
moves the point), a curve after a straight segment joins it tangent.
- On existing paths it selects and moves points, removes a point keeping
the shape (Alt-click), toggles smooth/corner (double-click), drags
handles, reshapes a segment by dragging it and inserts a point on it
(Alt-click); it closes, continues and joins open paths.
- The Smart Pen panel: next segment straight or curved, remove points
keeping shape, make smooth, make corner, retract handles, close or
join.
The tool stays out of both toolbars as shipped; the All Tools drawer
lists it under the add-on's heading. Commands are addon.pen.*; the
existing Pen tool, commands and menus are unchanged.
An anchor added to a path that wasn't selected now selects that path,
the new anchor direct-selected, so the point shows and can be edited at
once instead of only after a Direct Selection click. Undo restores the
old selection; a path already selected (the Pen's Auto Add) keeps it.

object.transformEach refused reflectX, reflectY, random and copy given
as text, but read strokes, corners, objects and patterns given as text
as the key left out. With Scale Strokes & Effects on,
{"scaleH": 200, "scaleV": 200, "strokes": "false"} scaled the stroke,
recorded an undo step and kept the params for Transform Again, which
repeated the call. artboard.rearrange, artboard.move and
artboard.duplicate read their patterns option the same way, and
artboard.setProps reads its patterns, strokes and corners options the
same way.
These commands now refuse such a value with "`<key>` must be true or
false" before they change anything. So do the other options and
numbers of artboard.setProps and artboard.move, the art of Duplicate,
Copy and Cut Artboard, the shape commands and path.create, path.close,
path.setHandle, path.moveAnchors, the Pencil, Curvature, Reshape
Segment and Blob Brush options, text.create, text.createInPath,
text.setRangeStyle, text.editRange, text.getRange, text.touchType,
text.areaOptions, type.step, the font size steps,
type.opticalMarginAlignment, type.systemLayout, type.fractionalWidths,
type.ruby, the symbol and swatch commands, the Appearance panel's
commands, the gradient and freeform gradient commands, Shape Builder,
Live Paint, Image Trace, the opacity of object.setProps, the radius,
sides and relativeRadii of object.setLiveShape, the reference point of
object.setBounds and the artboard of Align, Distribute and Distribute
Spacing. They refuse a number given as text with "`<key>` must be a
number, not <value>", and a gradient stop's tint with "stop <n>:
`tint` must be a number". A null still reads as the key left out.
Docs: docs/mcp.md, docs/target-app-parity.md.
Join can set the surviving junction point to a corner or smooth anchor via `to`, matching Illustrator's join choice without a combined Average+Join command.

With the Anchor Point tool, a drag from an anchor pulls out smooth handles.
Shift held at the press now moves the anchor instead, its handles keeping
their offsets; Shift kept down during the drag keeps the move at 45° steps
(the constrain angle), released it frees it. A Shift-click that doesn't
move leaves the anchor as it was. A selected blend's spine points follow
the same rule (object.blend.spine.moveAnchor).
The move goes through a new engine command, path.moveAnchor
{id, subpath?, anchor, x, y}, since path.moveAnchors only acts on the
direct-selected anchors and the Anchor Point tool keeps no anchor selection.

path.curvatureEdit, path.removeAnchor, path.convertAnchor,
path.reshapeSegment, path.split, path.setHandle and path.insertAnchor
read subpath as an unsigned integer and fell back to 0 for any other
value. A subpath of 1.5, -1 or "1" edited subpath 0 and the command
reported success. path.split read anchor and segment with as_u64 too
and treated any other value as absent, so a bad anchor beside a good
segment split at the segment.
These commands now refuse a subpath that is not a whole number of 0 or
more with "missing integer `subpath`", the error path.curvatureEdit,
path.removeAnchor, path.convertAnchor and path.reshapeSegment already
give for a bad anchor or segment, and path.split refuses such an anchor
or segment too. Without a subpath, or with null, they edit subpath 0 as
before. The document and the undo history stay as they were after each
error. The params text of the six commands that listed subpath as
required now marks it optional.
Docs: docs/mcp.md, docs/target-app-parity.md.
anchor_arc_distance measured every segment again for each anchor, so a reshape cost the square of the anchor count; path.reshape now measures the positions once, and the two helpers only it used are gone. The default radius stays half the subpath's bounding-box diagonal, now measured along the path: half its length reached the far corners of a square, moving art the grab is nowhere near (reshape_moves_the_grabbed_point_and_its_neighbourhood).
Keep surviving drawable runs separate when Delete or Backspace removes an open-path anchor. Preserve appearance, selection and one-step Undo.
