ui

Overview ¶

Package ui exposes a thin Lua binding over Fyne v2 widgets and windows. The Fyne-backed implementation (ui_fyne.go) is opt-in behind the `luascript_ui` build tag, since it drags in OpenGL/cgo and needs a C toolchain. By default ui_stub.go substitutes a no-op loader so a plain `go build ./cmd` stays pure-Go and dependency-light; `require("ui")` still resolves, only failing if a script actually constructs a widget. This file is the tag-agnostic entry point both code paths share.

Stub `ui` loader used by default (the Fyne implementation is opt-in via the `luascript_ui` build tag). Keeps the interpreter free of the Fyne/OpenGL/cgo dependency — so a plain `go run ./cmd` needs no C toolchain. `require("ui")` still succeeds at the package.preload stage and only panics when the script actually calls a constructor, matching how other optional drivers (native/db driver_postgres.go and friends) signal unavailability.
