A piece linked to a global swatch is drawn in the swatch's current color at its own tint, and kept art and rasters follow a color or spot edit and its Undo. A value of `paintOutput` other than true is refused by a translated error. Tests in the effects crate pass the new document argument.
app.open with params and no importer ran file.open with the path alone, so the desktop app ran the importer on its defaults while headless app.open passed the params to document.open. file.open now carries params to the importer that opens the file.
The importer parameters test installs its module with replace from the second pass on, as plugin.install requires. The permission table in docs/plugins.md lists doc.read for filter, effect and exporter.
plugin.install wrote the grant and the module as two separate writes,
and either could fail with only a log record. With a grant tied to the
module's hash, the stored pair then no longer matched and the plug-in
was skipped at the next start.
The module is now written first and its grant only once it is there.
When the grant can't be written, the store gets its old module back, or
loses the new one on a first install, and a disabled plug-in stays
disabled. A stored module that can't be read back is not replaced by
one that needs a grant.
A module that lists no permissions now removes the grant from grants.json only after it has replaced the stored module. When the write fails, the old module stays stored and keeps the grant it needs at the next launch.
`plugin.install` accepted `grant` and `allowHeavy` from any client, so
the program installing a plug-in could answer its own permission
prompt.
The desktop app now shows an approval dialog that names the module,
its hash and what it asks for. Confirming it gives the engine a
one-use approval tied to that module id, hash and permission list. A
control or MCP request and a frame of synthetic input cannot confirm
the dialog, and Enter does not confirm it.
Without such an approval, `grant` and `allowHeavy` are refused. The
new `--allow-plugin-grants` flag on `mcp` and `run` lets a person who
starts a headless session accept them from requests. The flag cannot
be combined with `--connect`. A module already approved in the desktop
app still installs through its stored grant.
Installing a module that lists no permissions under a granted id now
forgets the grant, in the process and in grants.json, so the formerly
approved bytes need a new approval. A refused install leaves the grant.
Attaching a plug-in store forgets the grant of an id whose stored module
lists no permissions. A plug-in folder load forgets the process's grant
for such an id and leaves grants.json alone, because the store keeps the
module its grant covers.
Object > Expand of gradient and pattern fills now expands the pieces a
painted live effect draws one by one, so a piece keeps its own paints.
A later painted effect on a fill replaces only the first fill of a piece
and leaves the piece's other fills in place.
Document Info passes the document when it reads an image's painted fills.
File › Place reads only built-in formats, so a dropped file that only an
importer reads failed with a place error. It now opens as File › Open
opens it, with or without a drop position, also when an exporter lists
the same extension.
A plug-in of the wrong kind now gets "is a plug-in of kind `exporter`, not an importer", with rows in every complete-message catalog. The importer failure test also covers an open, edited document. docs/plugins.md states that Open Recent does not remember Open With's importer or parameters.
The reference check now applies wherever a painted effect's geometry is
used: a result whose swatch or pattern is refused keeps its input instead
of giving its geometry. Pathfinder art of type, reshaped groups, compound
shapes, image fills, the renderer's bounds and Object > Expand look the
references up in the document, and the renderer drops its kept bounds and
geometry when the names of the swatches or patterns change.
A grant records the module's SHA-256, but only its permissions were
compared, so a module with other bytes under a granted id inherited the
grant when it listed no new permission.
A grant now covers a module only when the id, the SHA-256 and every
listed permission match. plugin.inspect reports needsApproval for a
changed module, plugin.install refuses it without a new grant and leaves
the installed module and its grant as they are, Install Plug-in and
File > Open ask again, and the plug-in store and plug-in folders skip it.
The same bytes install again without asking, and a module with no
permissions list or an empty one needs no grant. A grant whose hash is
not 64 lower-case hexadecimal digits covers nothing.
plugin.install still trusts the client that sends grant; the docs say so.
File › Open With reads a picked file on the thread File › Open uses, with the importer and its parameters, so a slow importer does not freeze the window. A call that names path still gets document.open's result. Cancel in the progress window now raises a cancel token on that thread, which stops a running importer between two slices of its budget.
An importer may declare an extension that File › Open handles another
way: a plug-in, shortcut set, script, preset, library or swatch library
such as .ase, or one a built-in format reads. "All readable files" and
the importer's own filter no longer list those extensions, and an
importer with none left gets no filter. Open With still opens them.
A key that a paint does not have, such as `opacity` on a solid fill, was
dropped when the paint was read, and the fill was drawn opaque. The
result is now refused and `lastError` names the field, for keys on the
paint and on its colors, gradient, stops, placement and freeform points.
Pathfinder effects, compound shapes, Expand Appearance and pattern
expansion now pass the document to the effects they evaluate, so a
painted piece that names a swatch or pattern takes part as drawn instead
of being refused. A path with a painted effect takes part in Pathfinder
and compound shapes as its pieces, each with its own paint, inside the
path's opacity and blend mode.
The renderer's kept effect art and live evaluations now count the
document's swatch and pattern names for objects with a plug-in effect,
so deleting or restoring a swatch a piece names redraws the object.
New from Template, Load Character/Paragraph/All Styles, Recolor's Other
Library… and the library panels' Other Library… read files with the
built-in readers, so their open dialogs now use builtin_open_filters(),
which leaves out the extensions only importer plug-ins read. File › Open
keeps open_filters() with the importers' files.
The artboard of a document an importer opens is now kept within
±4,000,000 pt. Art at the edge (a zero-width path at x = 4,000,000, or a
stroke past the edge) gave an artboard beyond it, and every later edit
of the document was rejected.
File › Open With asks for the parameters of an importer that declares
any, at their defaults, once the file is picked (dialog `pluginImport`),
and opens the file with the values set. `file.openWith`, `app.open` and
MCP's `open_file` take `params` and pass them to the importer;
`app.open` without them runs the importer on their defaults, with no
dialog. A file opened with Open With is added to Open Recent, as File ›
Open adds the files it opens.
A filter's input is now encoded within the half of the plug-in's memory
cap that the input and the parameters share. Every object counts toward
it in paint order, with its id, bounds, transform and name. Type runs
and image pixels that don't fit what is left come with truncated or
pixelsOmitted, and a type, image or symbol instance whose other fields
alone don't fit fails the run before the plug-in starts with
"memory budget (object N needs S bytes of input, L left)".
A filter manifest that lists `inputs` must now list `doc.read` in
`permissions`, so installing it asks the user to grant them and the
Additional Plug-ins Folder loads it only once granted. Left out, the
manifest does not install.
The pixels of all images in one filter input take at most 16 MiB of
base64, and the runs and paragraphs of all its type at most 16 MiB of
JSON. An image whose pixels do not fit what is left comes with
`pixelsOmitted`, checked before it is decoded, and type that does not
fit comes with `truncated`. The read-only objects are kept once and
written into the input from there.
A field a filter adds to a read-only object is named in the refusal
with control and bidirectional characters escaped, cut to 64
characters.
A filter manifest at `api` 2 may list `inputs` (`type`, `image`,
`symbolInstance`). Such a filter is also given the selected objects of
those kinds, read only: type with its runs and paragraph attributes,
images with their pixel size, color mode and, when embedded and small
enough, their RGBA pixels in base64 (never a linked file's pixels or
path), and symbol instances with their symbol and transform.
The output must return each read-only object as {"id": ...} alone or
exactly as given. A change, an omission or a duplicate is refused
before the edit, so the document and undo history stay as they were,
including for output handed in from a heavy run. A filter without
`inputs` gets the same input bytes as before.
A manifest that lists `inputs` below `api` 2, outside a filter, with an
unknown or repeated kind, or with a permission list that lacks
`doc.read` does not install.
Part of #4333
A live effect whose manifest has "api": 2 and "paintOutput": true returns
{"objects": [...]} as pieces, each drawn by itself in order with fills and
strokes of its own in the forms a filter returns. A piece without fills or
strokes keeps the ones the effect was given, and an empty list paints none.
An effect on a fill returns only fills, one on a stroke only strokes.
The whole result is checked before any of it is drawn: the output limits,
finite numbers in range with nothing clamped, known keys only, and every
swatch and pattern it names in the document. One fault draws that step of
the stack unchanged, keeps the effect record and puts the plug-in's name
and the field in plugin.info's lastError. Each piece counts against the
geometry-effect budget, so the painted effects of one stack make at most
100,000 pieces.
The pieces are drawn, measured and exported to PDF and SVG from the
appearance stack without changing the document, and Expand Appearance
writes them as ordinary paths in one undo step. The plug-in API level
rises to 2; plugin.list and plugin.info give api and paintOutput. Effects
without the key behave as before.
An importer plug-in (kind "importer", permission import.read) lists 1 to 8
file extensions and turns a file's bytes into objects, which open as a new
document whose artboard is their bounds. File › Open lists its extensions,
File › Open With (file.openWith) opens a file with a chosen importer, and
document.open takes importer and params. A built-in format that reads the
file by its content or extension always opens it; among importers listing
the same extension, the one whose id sorts first opens it. An importer reads
at most 128 MiB, and Place still reads only the built-in formats.
Docs: docs/plugins.md, docs/mcp.md, docs/gaps.md, docs/target-app-parity.md.
A grants.json entry this version can't use (a permission it doesn't know,
an invalid id) is now skipped on its own instead of dropping every grant in
the file, and recording or removing a grant writes it back unchanged,
except an entry for that plug-in. A grants.json that is too large, can't be
read or is not a JSON list is left as it is, and a rewrite that would pass
the 1 MiB read limit is written compactly, or not at all.
The fuzz test for hostile host import arguments drew vc_log's level from every i32, so almost
every call stopped at the level check and never read memory. Levels are now also drawn from -1
to 4. The module docs, a test doc comment and docs/plugins.md now say that with an unknown total
each change of done is passed on.
A plug-in whose manifest gives "api": 2 and lists the new `progress`
permission may import three host functions from module `env`:
vc_progress(done, total), vc_cancelled() -> i32 and
vc_log(level, ptr, len) -> i32. Installing checks every import and
refuses, by name, one the host doesn't offer, one with another type and
one the manifest doesn't allow.
- Progress is clamped and passed on once per tenth of a percent (past
2,000 reports, once per 1,000 changes). A heavy filter's progress
window and the export's progress window show it as a percentage bar,
and their Cancel makes vc_cancelled return 1. A live effect's progress
is not shown.
- A run cancelled before it returns ends as cancelled, and one that
returns after its time budget ran out ends at that budget, so what a
plug-in returns after it sees vc_cancelled changes nothing. This also
applies to a plug-in of API level 1 that finishes after a Cancel or
past its time budget.
- Log text must lie in the module's memory and be UTF-8. Lines go to the
app's log as "<id>: <text>" with hidden characters escaped, at most
1,024 characters a line, 200 lines and 32 KiB a run, and the host reads
at most 1 MiB of log text a run.
- plugin.list and plugin.info give the manifest's `api`; the install
prompt names the new permission in plain words.
Docs: docs/plugins.md, docs/mcp.md, docs/target-app-parity.md.
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.
Docs: docs/plugins.md, docs/mcp.md, docs/target-app-parity.md.
A live effect that declares commands may list `doc.write` and `state`, and
gets them when its manifest leaves `permissions` out, as a filter does. Only
its commands use them: drawing the effect changes no object and keeps no
data. Before, every output of such a command that changed an object was
refused, since a live effect could never hold `doc.write`.
plugin.run and plug-in commands read `ids` strictly: a value that is not
a list, or an entry that is not a non-negative integer, is an error
naming `ids` ("ids must be an array of non-negative integer object
ids"). Left out or null, `ids` is still the selection.
A new test shows that a plug-in command that runs out of its
instruction budget leaves the document and the undo history unchanged,
and that the error names the plug-in and the command.
docs/plugins.md and docs/mcp.md name MCP's `command_list` and
`list_commands` as the listings that show plug-in commands, and the
params text, docs and progress line describe the `ids` rule.
A filter or live effect may declare up to 32 `commands` in its manifest,
each `{id, label, params?}`. While the plug-in is installed each one is the
command `plugin.<id>.<command>`: listed by `command.list` and in the
plug-in's `plugin.list` entry, run through `run`, MCP and `command.batch`
with its parameters checked before the plug-in runs, and recorded in
actions. A run goes through `vc_run` on the selection with
`_context.mode` "command" and `_context.command`, under the plug-in's
permissions, as one undo step named after the command. A failing run
leaves the document as it was, and its error starts with the plug-in's
name and the command's label. Removing or replacing the plug-in removes
its commands.
In the app, a plug-in with commands is a submenu named after it under
Object › Plug-ins (Effect › Plug-ins for a live effect), holding its own
item and then its commands; a `menu` key in a manifest is ignored. A
command with parameters opens a dialog for them from its menu item or a
shortcut. Edit › Keyboard Shortcuts lists the commands for the user to
give a shortcut; a manifest cannot set one. Labels and names are shown
with control and bidirectional characters escaped, and a malformed entry
is refused by name when the module is installed.

A manifest may list `permissions` (doc.read, doc.write, state,

unknown, reserved, duplicate or wrong-kind name is refused by name. A

prefs.set did not check the folder given as recoveryFolder or pluginsFolder,
beyond the automation roots check, so a control or MCP caller could save a
folder that does not exist, a file, or a folder the app cannot use. Only the
Preferences dialog checked the folder itself.
The dialog's folder checks move to the engine, and prefs.set runs them after the
automation roots check. A folder that fails returns the same error the dialog
shows, and no preference changes. An empty value, an omitted value and a folder
the preference already holds are not checked. The Wasm build skips the check, as
the dialog did. The dialog's OK now gets the check from prefs.set, and Choose…
calls the moved check directly.
Additional Plug-ins Folder (Plug-ins & Scratch Disks) gets the Choose…
button that Data Recovery's Folder has, on hosts with a folder picker.
A picked plug-ins folder must be a folder whose contents can be listed;
otherwise the status bar says why and the field keeps its value.
OK now gives a folder typed into either field the same check as a
picked one. When it fails, the dialog stays open, the status bar says
why and no preference is set. An empty field and the folder already
saved are not checked. Under automation roots, a folder outside them is
refused before it is looked at.
Additional Fonts Folder and Templates Folder stay typed only.
A compound path a filter made a guide was still given to later filters, which
could change or delete it; compound paths of guide paths are now left out as
guide paths are. Hex colors and the color button's choice are display sRGB and
are now converted into the working RGB space, so they show as given whatever
the working profile; a color default is kept as written and read when used.
Follow-up to #5630.
