Pure Go Text/Code Editor Widget
GPU-accelerated, embeddable, zero CGO.
gogpu/editor is a reusable native text and code editor widget for Go — like Monaco Editor but for Go desktop and WASM applications. GPU-accelerated rendering via gogpu/gg, widget system via gogpu/ui.
- Embeddable — drop into any Go application as a widget
- GPU-accelerated — glyph atlas, ClearType LCD, MSDF fallback
- Pure Go — zero CGO, cross-compiles everywhere (Windows, macOS, Linux, WASM)
- Code editor — syntax highlighting, line numbers, code folding
- Rich text — multi-font, styled runs, WYSIWYG editing
- IDE-ready — LSP client, DAP client, minimap, diagnostics
🚧 Early development. Architecture defined in ADR-028 (internal).
