All issues identified across Sections 3.1, 3.2, and 3.3 have been
resolved, verified with unit tests, automated compilation checks under
`-D float_literal_f32_fallback`, and headless SVG export runs.
-
**[angle.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/src/general/angle.rs)**:
- Implemented `From<f64>` and `From<usize>` for `Degrees`.
- Added unit tests `from_integer` and `from_f64` to verify conversion
accuracy.
-
**[fontsize.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/src/general/fontsize.rs)**:
- Implemented `From<f64>` for `FontSize`.
- Refactored `FontSize::value(self)` to pass Copy type by value.
- Added unit test `font_size_conversions`.
-
**[general.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/src/general.rs)**:
- Implemented `From<f64>`, `From<i32>`, and `From<usize>` for
`AnimationSpeed`.
- Added unit test `animation_speed_conversions`.
- Re-exported `macroquad` crate (`pub use macroquad;`) so downstream
code and macro expansions have reliable direct access.
-
**[export.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/src/export.rs)**:
- Made `parse_svg_export_arg()` public.
- Implemented `run_headless_svg_export<F>(mut build_commands: F,
filename: &str) -> Result<(), ExportError>` that executes commands
using `app.step_animations()`, avoiding all window/GUI dependencies
and never calling `std::process::exit`.
- Updated `handle_svg_export` to delegate to
`run_headless_svg_export`.
-
**[lib.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/src/lib.rs)**:
- Extracted `pub fn step_animations(&mut self)` from `update(&mut
self)`, allowing command queue draining and tween stepping
headlessly without querying window mouse position or events.
-
**[state.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/src/state.rs)**:
- Changed `TurtleWorld::new()` to initialize camera with
`Camera2D::default()` instead of querying `screen_width()` /
`screen_height()`, eliminating panics when running without a
Macroquad window.
-
**[turtle-lib-macros/src/lib.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib-macros/src/lib.rs)**:
- Added `validate_input` helper providing clean compile diagnostics
with spans for:
- Multiple arguments: `#[turtle_main] functions must take either 0
arguments or a single &mut TurtlePlan`
- Non-unit return types: `#[turtle_main] functions cannot have a
return type`
- Async functions: `#[turtle_main] functions cannot be async`
- Replaced `#[macroquad::main]` wrapper expansion with a native `fn
main()` that inspects CLI arguments first. If `--export-svg` is
present, it runs `run_headless_svg_export` directly and returns
cleanly without opening a window. Otherwise, it launches
`macroquad::Window::new(#window_title, async { ... })`.
- Added 5 unit tests in `turtle-lib-macros` testing signature
validation.
-
**[.vscode/launch.json](file:///home/dietrich/Projekte/Source/turtlers/.vscode/launch.json)**:
- Removed stale references to nonexistent `turtle-example` and
`turtle-ui`.
- Added debug configurations for `turtle-lib` tests,
`turtle-lib-macros` tests, `hello_turtle`, and `breadboard`.
-
**[breadboard.rs](file:///home/dietrich/Projekte/Source/turtlers/turtle-lib/examples/breadboard.rs)**:
- Refactored example to use `#[turtle_main("Breadboard")]`.
- Removed `#[cfg(feature = "svg")]` and the early-exit message; the
example now renders directly on screen by default and supports
`--features svg -- --export-svg breadboard.svg`.
-
**[README.md](file:///home/dietrich/Projekte/Source/turtlers/README.md)**:
- Documented optional user-level `~/.cargo/config.toml` mold/lld
fast-linking configuration under "Building and Running".

```bash
cargo test --workspace
```
- **Result**: 21 passed (16 in `turtle-lib`, 5 in `turtle-lib-macros`),
34 doctests passed, 0 failed.
```bash
RUSTFLAGS="-D float_literal_f32_fallback" cargo check --workspace
--all-targets --all-features
RUSTFLAGS="-D float_literal_f32_fallback" cargo check --package
turtle-lib --examples --all-features
```
- **Result**: Passed with 0 errors and 0 fallback warnings across all
workspace crates and all 30 examples.
```bash
cargo run --package turtle-lib --example hello_turtle --features svg --
--export-svg hello.svg
cargo run --package turtle-lib --example breadboard --features svg --
--export-svg breadboard.svg
```
- **Result**: Both exported SVG files successfully and exited with code
0 without creating or flashing a graphical window.
```bash
cargo check --package turtle-lib --example breadboard
```
- **Result**: Compiled cleanly with 0 errors when SVG feature is
disabled.
