## [0.1.0] - 2026-03-04



Initial public release.



### Added



- **View DSL** — declarative macros (`panel`, `row`, `column`, `text`) for building terminal UI trees

- **Elm-inspired architecture** — `init/handle_event/render` pattern via `ElixirOpentui.Component`

- **11 widgets** — TextInput, TextArea, Select, TabSelect, Checkbox, ScrollBox, Code (syntax highlighting), Markdown, Diff, LineNumber, and ScrollHelper

- **Flexbox-inspired layout engine** — rows, columns, padding, margin, grow/shrink, alignment, percentage sizing, min/max constraints

- **Zig NIF rendering backend** — double-buffered, diff-based terminal output for minimal flicker

- **Pure Elixir fallback renderer** — everything works without the NIF, just slower

- **Animation system** — timeline-based with 25 easing functions, ~30 FPS live mode

- **Full input handling** — keyboard events, mouse support (SGR 1006), paste detection, Kitty keyboard protocol

- **Terminal capability detection** — progressive enhancement based on terminal features

- **Syntax highlighting** — via Makeup, supports Elixir and TypeScript

- **Markdown rendering** — via Earmark, with headings, lists, code blocks, and blockquotes

- **Precompiled NIF binaries** for 8 platforms (x86_64/aarch64 Linux gnu/musl, macOS, FreeBSD)

- **17 runnable demo examples** in `demo/`

- **57 test files** covering widgets, layout, rendering, input parsing, and animation
