//! Version string utilities for thru binaries.
//!
//! Provides a macro to generate version strings with git info.
//! The macro must be used because env vars are resolved per-crate at compile time.

/// Generate a version string with git info.
///
/// Returns format: "0.1.0+abc1234" or "0.1.0+abc1234-dirty"
///
/// # Example
/// ```ignore
/// use thru_base::get_version;
/// let version: &'static str = get_version!();
/// ```
#[macro_export]
macro_rules! get_version {
    () => {{
