# 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`
|
|
````
|
|
build = "build.rs"
|
|
````
|
|
|
|
List rustc_tools_util as regular AND build dependency.
|
|
````
|
|
[dependencies]
|
|
rustc_tools_util = "0.1"
|
|
|
|
[build-dependencies]
|
|
rustc_tools_util = "0.1"
|
|
````
|
|
|
|
In `build.rs`, generate the data in your `main()`
|
|
````rust
|
|
fn main() {
|
|
println!(
|
|
"cargo:rustc-env=GIT_HASH={}",
|
|
rustc_tools_util::get_commit_hash().unwrap_or_default()
|
|
);
|
|
println!(
|
|
"cargo:rustc-env=COMMIT_DATE={}",
|
|
rustc_tools_util::get_commit_date().unwrap_or_default()
|
|
);
|
|
println!(
|
|
"cargo:rustc-env=RUSTC_RELEASE_CHANNEL={}",
|
|
rustc_tools_util::get_channel().unwrap_or_default()
|
|
);
|
|
}
|
|
|
|
````
|
|
|
|
Use the version information in your main.rs
|
|
````rust
|
|
use rustc_tools_util::*;
|
|
|
|
fn show_version() {
|
|
let version_info = rustc_tools_util::get_version_info!();
|
|
println!("{}", version_info);
|
|
}
|
|
````
|
|
This gives the following output in clippy:
|
|
`clippy 0.0.212 (a416c5e 2018-12-14)`
