Build / validate (pull_request) Has been cancelled
heph-core gains a build.rs that captures the short git SHA and a
`heph_core::VERSION` const ("<crate-version> (<sha>)"); heph and hephd use it
for clap's --version. The crate version stays sourced from Cargo.toml.
release.yaml now bumps the workspace version into Cargo.toml + Cargo.lock on a
commit that only the tag points at, tags it manually, and pushes just the tag —
so cargo install --git --tag vX.Y.Z reports the real version while main stays at
0.0.0. The changelog commit moved ahead of the tag so the release includes its
own changelog.

//! Build script: capture the short git SHA this build came from so the CLI
|
|
//! surfaces can report `<version> (<sha>)`. The crate version itself comes from
|
|
//! `Cargo.toml` (bumped to the release version on the release tag — see
|
|
//! `.forgejo/workflows/release.yaml`); this only adds the provenance suffix.
|
|
//!
|
|
//! Resolution order: the `HEPH_BUILD_SHA` env override (an escape hatch for
|
|
//! builds with no `.git`, e.g. a source tarball) → `git rev-parse` → `unknown`.
