shadow-formatted-version

Convenience crate to provide detailed version information in a preformatted block:

  Version:       0.1.0
  Target:        x86_64-unknown-linux-gnu
  Commit:        8f29a49b54ca3e94070d244511d8e4a64a69f083
  Commit-Date:   2023-12-31 23:59:59 +00:00
  Build-Date:    2024-12-31 23:59:59 +00:00
  Build-Clean:   No uncommitted changes in build.
  Rust-Version:  rustc 1.76.0 (07dca489a 2024-02-04)

This version information can be logged at the start of a long-running service or
printed when passing --version to a CLI.

For example, when using clap, you can use it like so:

#[derive(Parser)]
#[command(about, version, long_version=crate::FORMATTED_VERSION)]
struct Args {
    // ...
}

Setup

This crate is based on shadow-rs, which we will setup as well.

1. Add shadow-rs and shadow-formatted-version to your dependencies:

[dependencies]
shadow-rs = "1"
shadow-formatted-version = "0.1"

[build-dependencies]
shadow-rs = "1"

2. Add the following code to your build.rs file:

fn main() -> shadow_rs::SdResult<()> {
    shadow_rs::new()
}

If you don't yet have a build.rs file, place it next to your Cargo.toml file:

.
├── build.rs
├── Cargo.toml
└── src
    └── ...

3. Place these two lines in your main.rs or lib.rs, underneath your module definitions:

shadow_rs::shadow!(build)
formatted_version::from_shadow!(build);

Then you can retrieve the formatted version information with crate::FORMATTED_VERSION.
You can also retrieve additional constants from crate::build, as generated by shadow-rs.
