Jade 6c2199ea9f rfc3052: Remove authors field from Cargo manifests Since RFC 3052 soft deprecated the authors field anyway, hiding it from crates.io, docs.rs, and making Cargo not add it by default, and it is not generally up to date/useful information, we should remove it from crates in this repo.		2021-07-29 14:56:05 -07:00

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()

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

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)
