The previous commit added support for glutin 0.19.0. glutin 0.19.0 depends on winit 0.18.0, which requires rust 1.28.0 or later. Here is the full dependency chain: glutin 0.19.0 > winit 0.18 > smithay-client-toolkit 0.4.2 > andrew 0.1.4 > rusttype 0.7.3 > ordered-float 1.0.1 (on linux) ordered-float uses [repr(transparent)], which is now stabilised on latest rust, hence the requirement for rust 1.28.0.

# imgui-rs: Rust bindings for ImGui
|
|
|
|
**Still fairly experimental!**
|
|
|
|
Minimum Rust version: 1.28
|
|
|
|
Wrapped Dear ImGui version: 1.66
|
|

|
|
|
|
|
|
|
|
```rust
|
|
ui.window(im_str!("Hello world"))
|
|
.size((300.0, 100.0), ImGuiCond::FirstUseEver)
|
|
.build(|| {
|
|
ui.text(im_str!("Hello world!"));
|
|
ui.text(im_str!("こんにちは世界！"));
|
|
ui.text(im_str!("This...is...imgui-rs!"));
|
|
ui.separator();
|
|
let mouse_pos = ui.imgui().mouse_pos();
|
|
ui.text(im_str!("Mouse Position: ({:.1},{:.1})", mouse_pos.0, mouse_pos.1));
|
|
})
|
|
```
|
|
|
|
## Currently implemented things
|
|
|
|
* Low-level API (imgui-sys)
|
|
* Renderer for easy integration with [Glium](https://github.com/tomaka/glium) projects (optional)
|
|
* Parts of high-level API
|
|
* Not horrible way of defining and passing null-terminated UTF-8 to ImGui.
|
|
The macro `im_str!` needs to be used most of the time. For more
|
|
information and justification for this design, please see [issue #7](https://github.com/Gekkio/imgui-rs/issues/7)
|
|
* Parts of imgui\_demo.cpp reimplemented in Rust as an API usage example (examples/test\_window\_impl.rs)
|
|
|
|
## Important but unimplemented things
|
|
|
|
* Documentation (rustdoc)
|
|
* Support passing a custom Program to Glium renderer (e.g. from a shader cache, or custom shader)
|
|
|
|
## Core design questions and current choices
|
|
|
|
* Closures VS begin/end pairs (current choice: closures)
|
|
* Mutable references VS return values (current choice: mutable references)
|
|
* Passing around Ui<'ui> VS passing around &'ui Ui (current choice: Ui<'ui>)
|
|
* Splitting the API to smaller pieces VS all draw calls in Ui (current choice: all draw calls in Ui)
|
|
* Builder pattern for optional arguments VS something else (current choice: builder)
|
|
* Mutation functions in builders VS self-consuming functions in builders (current choice: self-consuming)
|
|
|
|
## Compiling and running the demos
|
|
|
|
Examples are under the imgui-examples directory.
|
|
|
|
git clone https://github.com/Gekkio/imgui-rs
|
|
cd imgui-rs
|
|
git submodule update --init --recursive
|
|
cd imgui-examples
|
|
cargo test
|
|
|
|
cargo run --example hello_world
|
|
cargo run --example test_window
|
|
cargo run --example test_window_impl
|
|
|
|
Note to Windows users: You will need to use the *MSVC ABI* version of the Rust compiler along
|
|
with its associated [dependencies](https://www.rust-lang.org/en-US/downloads.html#win-foot) to
|
|
build this libary and run the examples.
|
|
|
|
## How to contribute
|
|
|
|
1. Change or add something
|
|
2. Run rustfmt to guarantee code style conformance
|
|
|
|
rustup component add rustfmt-preview
|
|
cargo fmt
|
|
|
|
