Description
Expected Behaviour
Expect the examples to work per the instrcutions in the docs + the clap help i.e
Usage: example-runner-wgpu.exe [OPTIONS]
Options:
-s, --shader <SHADER> [default: Sky]
--force-spirv-passthru
-h, --help Print helpExample & Steps To Reproduce
Here's a table summarizing which examples work and which don't:
| Command/Example | Works? |
|---|---|
cargo run --bin example-runner-wgpu |
Yes |
cargo run --bin example-runner-wgpu -- -s Sky |
Yes |
cargo run --bin example-runner-wgpu -- -s simplest-shader |
No |
cargo run --bin example-runner-wgpu -- -s mouse-shader |
No |
cargo run --bin example-runner-wgpu -- -s compute-shader |
No |
cd ./examples/shaders/compute-shader && cargo run |
Yes |
If you throw a dbg! print on the crate_name defined here:
// ./examples/runners/wgpu/src/lib.rs:140
let crate_name = match options.shader {
RustGPUShader::Simplest => "simplest-shader",
RustGPUShader::Sky => "sky-shader",
RustGPUShader::Compute => "compute-shader",
RustGPUShader::Mouse => "mouse-shader",
};The EnumString is working fine as in, clap is parsing it correctly.
I do not have time right now to investigate why -- perhaps the compilation logic in each of the individual shader crates' is wrong?
