//! VectorCraft tools: pointer events in → commands and overlays out. //! //! Tools never mutate the document directly. They emit [`Action`]s that the engine executes: //! `Begin` snapshots the document, each `Preview` re-applies one command on top of that snapshot //! (replacing the previous preview), and `Commit` records the last preview as a single undo step //! and journal entry. One-shot `Exec` actions run immediately. This makes every gesture replayable //! by the control channel and MCP, and keeps tools testable without a UI. #![forbid(unsafe_code)] pub mod bbox; pub mod builder; pub mod catalog; pub mod corners; pub mod cropimage; pub mod cut; pub mod direct; pub mod distort; pub mod draw2; pub mod extra; pub mod guides; pub mod meshblend; pub mod meshedit; pub mod params; pub mod pathtype; pub mod pen; pub mod place; pub mod printtiling; pub mod rulerguide; pub mod select; pub mod settings; pub mod shape; pub mod slice; pub mod symbolism; pub mod text; pub mod typewidget; pub mod xform; use serde::{Deserialize, Serialize}; use serde_json::Value; use vectorcraft_color::Paint; use vectorcraft_doc::{Document, NodeId, Selection, Unit}; use vectorcraft_geom::{BezPath, Point, Rect, Vec2}; pub use catalog::{TOOL_GROUPS, ToolInfo, tool_info}; /// Modifier keys. #[derive(Clone, Copy, Debug, Default, PartialEq, Eq, Serialize, Deserialize)] pub struct Mods { #[serde(default)] pub shift: bool, /// Option on macOS. #[serde(default)] pub alt: bool, /// Command on macOS, Ctrl elsewhere. #[serde(default)] pub cmd: bool, #[serde(default)] pub ctrl: bool, #[serde(default)] pub space: bool, } #[derive(Clone, Copy, Debug, PartialEq, Eq, Serialize, Deserialize)] #[serde(rename_all = "lowercase")] pub enum PointerKind { /// Button pressed.
