zerv
Dynamic versioning from git. Every commit gets its version. Keep semantic-release on main. Let zerv prerelease every other branch.
Documentation: zerv.wisl.dev
Why zerv?
- Runs next to semantic-release - semantic-release decides releases on main; zerv versions every other build: any commit on any branch, even with uncommitted changes. No build is ever unversioned.
- Two modes -
zerv flowautomates pre-release management from Git branch patterns;zerv versiongives full manual control with schemas, overrides, and templates. - Any output format - SemVer, PEP440, CalVer, or Tera templates. Generate every format your pipelines need from a single ZERV RON payload.
See how zerv compares to semantic-release, setuptools-scm, and git describe in Why zerv.
Installation
# Python (uv) - Recommended
uv tool install zerv-version
# Python (pip)
pip install zerv-version
# Rust (cargo)
cargo install zerv
# Installation script (latest, or `bash -s vX.X.X` for a specific version)
curl -sSL https://raw.githubusercontent.com/wislertt/zerv/main/scripts/install.sh | bash
# Pre-built binaries
# https://github.com/wislertt/zerv/releases
The PyPI wheel also exposes a Python binding: import zerv.
Quick Start
Version any Git state: zerv flow generates meaningful SemVer versions from any Git state, no manual configuration required.
# The current branch determines the output
zerv flow
# → 1.0.0 (on main branch with tag v1.0.0)
# → 1.0.1-rc.1.post.3 (on release branch with pre-release tag)
# → 1.0.1-beta.1.post.3+develop.3.gf297dd0 (on develop branch)
# → 1.0.1-alpha.59394.post.1+feature.new.auth.1.g4e9af24 (on feature branch)
# → 1.0.1-alpha.17015.post.1.dev.1764382150+feature.dirty.work.1.g54c499a (on dirty feature branch)
Fan one ZERV RON payload out to every format your pipelines need in the quickstart.
