imgui-ext¹

A crate to quickly build imgui UIs using annotations and a derive macro.

¹ The name imgui-ext follows the convention of adding an -Ext suffix to something that enhances an existing type. In this case, the imgui crate.

```rust use imgui_ext::UiExt;

[derive(imgui_ext::Gui)]

struct Example { #[imgui(slider(min = 0.0, max = 4.0))] x: f32, #[imgui(input(step = 2))] y: i32, #[imgui(drag(label = "Drag 2D"))] drag_2d: [f32; 2], #[imgui(checkbox(label = "Turbo mode"))] turbo: bool, }

ui.window(imstr!("README.md")) .size((300.0, 100.0), ImGuiCond::FirstUseEver) .build(|| { ui.drawgui(&mut example); }); ```

Examples

```bash

codegen example (see examples/codegen.rs to see the code generated by the macro)

cargo run --example codegen

several UI examples

cargo run --example ui

integration with nalgebra types

cargo run --example nalgebra ```

Limitations

• #[derive(imgui_ext::Gui)] is only supported for structs with named fields.
