//! # effectcraft-script (L4)
|
|
//!
|
|
//! Scripting with an After Effects-style object model, on the boa JavaScript engine (the one the
|
|
//! expressions use). Scripts written for After Effects' documented scripting API mostly run
|
|
//! unchanged:
|
|
//!
|
|
//! ```text
|
|
//! app.beginUndoGroup("Build");
|
|
//! var comp = app.project.items.addComp("Main", 1920, 1080, 1, 10, 30);
|
|
//! var solid = comp.layers.addSolid([1, 0, 0], "Red", 1920, 1080, 1);
|
|
//! solid.property("ADBE Transform Group").property("ADBE Position").setValueAtTime(0, [0, 540]);
|
|
//! solid.Effects.addProperty("ADBE Gaussian Blur 2").property("Blurriness").setValue(20);
|
|
//! app.endUndoGroup();
|
|
//! ```
|
|
//!
|
|
//! * **Object model** (`prelude.js`): `app` (project, open/newProject, undo groups,
|
|
//! `executeCommand`/`findMenuCommandId`, `scheduleTask`), `Project`, `ItemCollection`,
|
|
//! `CompItem`/`FootageItem`/`FolderItem`, `LayerCollection`, `AVLayer`/`TextLayer`/
|
|
//! `ShapeLayer`/`CameraLayer`/`LightLayer`, `PropertyGroup`/`Property` (values, keyframes,
|
|
//! eases, expressions), `MaskPropertyGroup`, `TextDocument`, `Shape`, `KeyframeEase`,
|
|
//! `MarkerValue`, `RenderQueue`/`RenderQueueItem`/`OutputModule`, `ImportOptions`, `File`/
|
|
//! `Folder`, `$`, `alert`/`writeLn`, and the enums (`BlendingMode`, `KeyframeInterpolationType`,
|
|
//! `TrackMatteType`, `LightType`, `ParagraphJustification`, `PropertyValueType`…).
|
|
//! * **Edits are engine commands**: every mutating call runs a command through
|
|
//! [`Session::execute`](effectcraft_engine::Session::execute), so it is undoable, journaled
|
|
//! and identical to the UI's action; `app.beginUndoGroup`/`endUndoGroup` fold everything in
|
|
//! between into one undo step.
|
|
//! * **Match names** ([`matchnames`]): After Effects' documented match names for our properties
|
|
//! and effects (`ADBE Transform Group`, `ADBE Position`, `ADBE Gaussian Blur 2`…).
|
|
//! * **Security**: scripts can import/open/save projects and render, but `File` reads are limited
|
|
//! to the project's folder and writes (and the network) are off unless Preferences ▸ Scripting
|
|
//! & Expressions ▸ Allow Scripts to Write Files and Access Network is on.
|
|
//! * **ScriptUI** (`scriptui.js`, `ui.rs`): `Window` (dialog / palette / window), `Panel`,
|
|
//! `Group`, `Button`, `StaticText`, `EditText`, `Checkbox`, `RadioButton`, `Slider`,
|
|
//! `Progressbar`, `DropDownList`, `ListBox`, `TabbedPanel`/`Tab`, with `add()`, `orientation`,
|
|
//! `alignChildren`, `alignment`, `margins`, `spacing`, `preferredSize`, `onClick` /
|
|
//! `onChange` / `onChanging` / `onClose`, `show()` / `close()` and `layout.layout()`. Windows
|
|
//! are published to [`Session::script_ui`](effectcraft_engine::Session::script_ui) for
|
|
//! frontends and agents (`scriptui.*` commands); modal dialogs block `show()` until they close.
|
|
//! Scripts in the ScriptUI Panels folder run with `this` = a dockable `Panel`. Resource
|
|
//! strings (`new Window("dialog { ok: Button { text: 'OK' } }")`, `add("group { … }")`) build
|
|
//! whole trees; `onDraw` handlers paint with `ScriptUIGraphics` (`newPen`/`newBrush`/`rectPath`/
|
|
//! `ellipsePath`/`moveTo`/`lineTo`/`fillPath`/`strokePath`/`drawString`/`measureString`) into a
|
|
//! serde draw list frontends paint; edit texts and sliders fire `onChanging` live.
|
|
//! * **Sockets** (`socket.rs`): `Socket` (`open`/`listen`/`poll`/`read`/`readln`/`write`/`close`)
|
|
//! over TCP, behind the same network preference; on the web `open` returns false.
|
|
//!
|
|
//! Entry points: [`install`] sets [`Session::script`](effectcraft_engine::Session::script), which
|
|
//! the `script.run` command, File ▸ Scripts ▸ Run Script File… (`.jsx`/`.js`), the Script Console
|
|
//! panel, `effectcraft-cli script` and the MCP `run_script` tool use.
