# rustc_tools_util
A small tool to help you generate version information
for packages installed from a git repo
## Usage
Add a `build.rs` file to your repo and list it in `Cargo.toml`
````toml
build = "build.rs"
````
List rustc_tools_util as regular AND build dependency.
````toml
[dependencies]
rustc_tools_util = "0.3.0"
[build-dependencies]
rustc_tools_util = "0.3.0"
````
In `build.rs`, generate the data in your `main()`
```rust
fn main() {
rustc_tools_util::setup_version_info!();
}
```
Use the version information in your main.rs
```rust
fn show_version() {
let version_info = rustc_tools_util::get_version_info!();
println!("{}", version_info);
}
```
This gives the following output in clippy:
`clippy 0.1.66 (a28f3c8 2022-11-20)`
