# Tweak Shader Runner
A simple demo application for the tweak shader library. It watches changes to a tweak shader file and displays errors as they arise. A few examples are available under `tweak_shader_examples` in the root directory.
The ui is powered by Egui.
## Usage
```
runner --file <tweak_shader_file>
### Building
```bash
cargo build
```
and
```bash
cargo run -- file tweak_shader_examples/<demo_file.fs>
```
To run the demo application.
if you want to use audio or video then the runner application requires the ffmpeg library installed due to the [ffmpeg_next](https://github.com/zmwangx/rust-ffmpeg) crate. Please
see the platform specific build instructions for ffmpeg_next.
```bash
cargo build --features audio video
```
