A CodeWarrior C++ symbol demangler.
### Usage
## Usage
CLI:
### CLI
Static binaries available from [releases](https://github.com/encounter/cwdemangle/releases) or install via `cargo install cwdemangle-bin`.
```shell
cwdemangle 'BuildLight__9CGuiLightCFv'
```
Library:
Pass `--help` to see available options.
### Library
- No dependencies
- `#![no_std]` compatible (requires `alloc`)
Cargo.toml:
```toml
[dependencies]
cwdemangle = "0.2"
```
Usage:
```rust
use cwdemangle::{demangle, DemangleOptions};
if let Some(result) = demangle("BuildLight__9CGuiLightCFv", &DemangleOptions::default()) {
println!("{}", result);
} else {
eprintln!("Couldn't demangle symbol (not a C++ symbol?)");
}
let result = demangle("BuildLight__9CGuiLightCFv", &DemangleOptions::default());
assert_eq!(result, Some("CGuiLight::BuildLight() const".to_string()));
