Extended Libraries

Beyond the core libraries, Plan9Basic includes an extensive set of GUI, animation, and visual effects libraries — enabling applets to build rich interfaces, animate elements, and apply visual transformations to controls. Documentation for these libraries is being developed progressively.

GUI — Forms & Controls

Window/form creation, sizing, positioning, events, and modal dialogs.

Push buttons with text, styling, click events, and state management.

Text labels with font, color, alignment, and auto-sizing support.

Single-line text input with validation, placeholder, and events.

Multi-line text editor with scrollbars, word wrap, and line access.

Checkbox controls with checked/unchecked state and change events.

Radio buttons with mutual exclusion groups and selection events.

Drop-down combo boxes with item lists and selection handling.

Scrollable list boxes with item management and selection modes.

Image display from file/URL, scaling, rotation, and bitmap operations.

Tabular data grid with rows, columns, cell editing, and scrolling.

Container panels for grouping and organizing controls.

Layout management for automatic control arrangement and flow.

Vertically-scrolling container with full alignment support, scroll bar control, and content size queries.

Toggle switch controls with on/off state and events.

Progress indicators with min/max, value, and orientation control.

Slider/trackbar controls for numeric range selection.

Toolbar-style speed buttons with glyph support and toggle state.

CalloutRectangleLib

Callout/tooltip shapes with configurable arrow position.

Timer controls with interval, enable/disable, and tick callbacks.

Audio/video playback with transport controls and media events.

GUI — Shapes & Drawing

Rectangle shapes with fill, stroke, corners, and opacity.

Rounded rectangles with configurable corner radius.

Circle shapes with fill, stroke, and positioning.

Ellipse shapes with independent width/height radii.

Arc shapes with configurable start and end angles.

Line drawing between two points with stroke styling.

Vector paths with move, line, curve, and close commands.

Pie/sector shapes with start and end angles, fill, and stroke.

Animations

Property Animations 6 libraries

FloatAnimationLib

Animate numeric properties (position, size, opacity) over time.

IntAnimationLib

Animate integer properties with step-based transitions.

ColorAnimationLib

Animate color transitions with smooth interpolation.

RectAnimationLib

Animate rectangle bounds (position + size combined).

PathAnimationLib

Animate objects along vector paths with easing.

BitmapListAnimationLib

Frame-by-frame sprite animation from bitmap sequences.

Visual Effects

Image & Filter Effects 41 libraries

Transition Effects 23 libraries

Artificial Intelligence

45 LLM functions: provider-agnostic client, chat, streaming, conversation history, token tracking, and multi-provider support (Claude, GPT, Gemini, Ollama, and more).

13 RAG functions: knowledge base indexing, semantic retrieval, budget-aware search, and document lookup for AI-assisted applets.
