nex-editor

nex-editor is being built as a headless Rust editor runtime with thin platform shells.

The current first milestone is intentionally narrow: a minimal plain-text editor that behaves like a notepad. Before adding rich-text structure, paging, or advanced rendering, the project is stabilizing:

• Rust-owned editing state
• Rust-owned layout and hit testing
• a small cross-platform event/render protocol
• a browser playground that only forwards events and draws snapshots

Web Playground

The repository now includes a minimal WASM-driven plain text playground at apps/web-playground.

cd apps/web-playground
npm install
npm run dev

That flow builds the WASM package from crates/wasm, writes it into apps/web-playground/src/wasm, and starts Vite. The playground shell forwards browser events into Rust and renders Rust-produced layout snapshots on canvas.

Today the playground target is only:

• click to place the caret
• type text
• delete text
• make selections
• move the caret with arrow keys
• render the result from Rust-owned layout data

Not in the current milestone:

• rich-text marks
• document schema UX beyond plain text
• pagination
• collaboration
• IME/composition completeness
