From c7cd72b09e5f5c4bdbd65d208832dc51532fc4cf Mon Sep 17 00:00:00 2001 From: dotCooCoo Date: Sat, 31 Oct 2026 04:28:23 -0700 Subject: [PATCH 01/12] M3: Selection colors rows apply library color styles and create a style A row's Styles menu lists this file's color styles (library copies are no longer listed as local), then each enabled library's published color styles under the library's name. Choosing a library style copies it in, linked and read-only, and applies it to every fill and stroke the row stands for in one undo step (selection.applyColorStyle with `library`). A row linked to a style or variable now has the Styles button too, so it can switch to another style. Create style on an ordinary row opens a window with the next free "Color n" name. Create makes a style of the row's whole paint (gradient stops, opacity and blend mode included) and links it to every target in one undo step (selection.createColorStyle {targets, name, description?}). A name another style has, an empty name, or a row whose slots no longer share one paint is refused, and the window stays open. Text ranges with fills of their own take the style's value without a link. --- crates/engine/src/cmd/library.rs | 2 +- .../engine/src/selection/selection_colors.rs | 78 +++++- crates/engine/tests/it/selection_colors.rs | 180 ++++++++++++- crates/ui-egui/src/panels/selection_colors.rs | 240 +++++++++++++++--- docs/ui-parity.md | 2 +- 5 files changed, 461 insertions(+), 41 deletions(-) diff --git a/crates/engine/src/cmd/library.rs b/crates/engine/src/cmd/library.rs index 5f3263765..8aeb12d49 100644 --- a/crates/engine/src/cmd/library.rs +++ b/crates/engine/src/cmd/library.rs @@ -194,7 +194,7 @@ fn with(p: &Value, keys: &[&str], mut base: Value) -> Value { } /// An enabled library of the active document (`library` param), read from its file. -fn library(s: &mut Session, cmd: &str, p: &Value) -> Result<(LibraryLink, Arc)> { +pub(crate) fn library(s: &mut Session, cmd: &str, p: &Value) -> Result<(LibraryLink, Arc)> { let key = req_string(cmd, p, "library")?; let link = find_link(s.doc()?, &key) .cloned() diff --git a/crates/engine/src/selection/selection_colors.rs b/crates/engine/src/selection/selection_colors.rs index 6ab99e819..b653f333b 100644 --- a/crates/engine/src/selection/selection_colors.rs +++ b/crates/engine/src/selection/selection_colors.rs @@ -5,14 +5,14 @@ use std::collections::{BTreeMap, BTreeSet}; use figcraft_color::{Paint, PaintKind}; -use figcraft_doc::{Document, NodeId, NodeKind, StyleKind, VariableType, VariableValue}; +use figcraft_doc::{Document, NodeId, NodeKind, Style, StyleKind, VariableType, VariableValue}; use serde::{Deserialize, Serialize}; use serde_json::{Value, json}; use crate::cmd::lists::{BoundList, list_binding, rebind_edited_paint}; use crate::cmd::styles::{rebind_paint_alpha, unbind_slot}; -use crate::params::{get, paint_of, parse, req_string, targets}; -use crate::{CommandSpec, Result, Session, bad, spec}; +use crate::params::{get, paint_of, parse, req_string, string, targets}; +use crate::{CommandSpec, EngineError, Result, Session, bad, spec}; #[derive(Clone, Debug, PartialEq, Eq, Hash, Serialize, Deserialize)] #[serde(rename_all = "camelCase", deny_unknown_fields)] @@ -127,10 +127,17 @@ pub fn specs() -> Vec { spec!( "selection.applyColorStyle", "Apply selection color style", - "{targets, style}; applies the color style to matching fill/stroke lists (text ranges keep typography)", + "{targets, style (id or name), library?

At a zoom of 1.7, a 1-unit cell is 1.7 pixels across and every tenth edge falls on a row of pixel centres; a render whose origin is a whole number of pixels off reached that edge with another rounding error and moved the row into the next cell. An edit over a textured layer patched up to 197 levels off a full render, and a noisy one 224. Cell positions are now rounded to 1/2^20 of a cell before they're cut into cells, and texture adds its scatter to the pixel index in whole pixels instead of flooring it in f32 together with the index.

Rounded cells with the old `f32` move still passed them. A pan across a 2,400-pixel-wide striped layer catches it: past 1,024 pixels, the old move came out a pixel off for some pixels.

Since 2026-10-17 (community batches #727, #728): an instance's own identity and the cached library components a file carries, overrides applied by key and order, local text values and instance overrides over a shared text style, grid track sizes (fixed, content-sized, fill), slot content, labels of connectors saved with their drawn path (a static snapshot; the ends aren't live), skip ink, paragraph options and hanging lists, list start numbers, vertical trim, per-point stroke joins, editable text on a path, image adjustments and images carried in the message; since 2026-10-29, style links that name a library style by asset key and version (the file's own copy of it), with override rows above the linking one still winning, and override rows restating a nested level's overrides applied at that level, below the instance's own (#1234), and the line breaks the file saved with a text, followed until an edit or a resize could move one, or where a line would come out more than 3% wider than its box in the fonts at hand (#1236). Budgets come from the file's own size (four decoded values per compressed byte, 20M–128M, lower ceilings on 32-bit targets; the layer cap follows the file's size too), so a 15.4 MB synthetic file with 300,000 layers opens whole; ZIP image reads have a separate total budget of 4 GiB (1 GiB on 32-bit targets) of decompressed ZIP-member bytes containing encoded images, with the 256 MiB per-image cap kept: a member that cannot fit is skipped before its output buffer is allocated, and the import report names the budget and counts skipped images (#1076). Failed reads and invalid image contents still consume the bytes read; a reference used by several layers is read once. This is not a limit on decoded pixels or total import memory; images carried inside the message are unchanged. The file's bytes stay out of the command journal; an import report lists what was left out or changed once the file opens. Elbowed and curved connectors without a saved path are routed as FigCraft's board connectors are (right angles, or one curve, from the sides of the layers they join), and a connector routed here takes its line's paint, weight, cap and dashes from the file's generated line record, as one with a saved snapshot does (#1807). A connector's label without a saved snapshot is kept as text centred on its line, without its background.
