Description

Running cortex plugin new my-plugin --advanced generates an advanced Rust plugin template whose src/lib.rs produces 7 compiler warnings when built. Three imports are unused: alloc::string::String, alloc::vec::Vec, and the alloc::vec macro. Two enum types have variants that are never constructed: UiRegion variants Header, Footer, SidebarLeft, SidebarRight (only StatusBar is used), and ToastLevel variants Warning and Error (only Info and Success are used). Two FFI functions declared in the extern "C" block are never called: get_context and emit_event. A freshly scaffolded advanced template should compile cleanly with zero warnings.

Error Message

warning: unused import: `alloc::string::String` (src/lib.rs:15)
warning: unused import: `alloc::vec::Vec` (src/lib.rs:16)
warning: unused import: `alloc::vec` (src/lib.rs:17)
warning: variants `Header`, `Footer`, `SidebarLeft`, and `SidebarRight` are never constructed (src/lib.rs:55)
warning: variants `Warning` and `Error` are never constructed (src/lib.rs:93)
warning: function `get_context` is never used (src/lib.rs:26)
warning: function `emit_event` is never used (src/lib.rs:30)
warning: `adv-test` (lib) generated 7 warnings

System Information

• Cortex TUI v0.0.7
• OS: Linux x86_64

Screenshots

Steps to Reproduce

1. Run cortex plugin new adv-test --advanced -o /tmp/test -d "Test" -a "Dev"
2. cd /tmp/test/adv-test
3. Run cargo build --target wasm32-wasip1 --release
4. Observe 7 compiler warnings about unused imports, dead enum variants, and unused FFI functions

Expected Behavior

The generated advanced plugin template should compile with zero warnings. The template should either use all declared imports, enum variants, and FFI functions, or not include the unused ones.

Actual Behavior

The advanced template includes 3 unused imports, 6 unused enum variants across 2 enums, and 2 unused FFI function declarations, producing 7 compiler warnings on every build.

[echobt]

The issue reports that the cortex plugin new --advanced command generates a Rust template (src/lib.rs) that produces 7 compiler warnings when built. The warnings are for unused imports (alloc::string::String, alloc::vec::Vec, alloc::vec), dead enum variants (UiRegion variants Header, Footer, SidebarLeft, SidebarRight and ToastLevel variants Warning, Error), and unused FFI functions (get_context, emit_event).

I verified the codebase by checking src/cortex-cli/src/plugin_cmd.rs which contains the RUST_ADVANCED_TEMPLATE. The template code confirms the bug:

1. It imports alloc::string::String, alloc::vec::Vec, and alloc::vec but never uses them.
2. It defines UiRegion with Header, Footer, SidebarLeft, SidebarRight, and StatusBar, but only uses StatusBar in register_widget_in_region(UiRegion::StatusBar, ...).
3. It defines ToastLevel with Info, Success, Warning, and Error, but only uses Info and Success in show_notification.
4. It declares get_context and emit_event in the extern "C" block but never calls them.

The screenshot is authentic and clearly shows the 7 compiler warnings matching the description. I also checked for duplicates and found issue #48552, but that issue is specifically about the basic template (cortex plugin new), which has a different set of warnings (3 warnings), whereas this issue is about the --advanced template (7 warnings). Therefore, this is a distinct and valid bug.
