Deterministic release name generator.

debaser turns a git SHA (or any hex-ish checksum) into a friendly, alliterative adjective-noun release name (for example: loony-lionfish).

Install

macOS (Homebrew)

Via tap (recommended):

brew tap nficano/tap
brew install debaser

Debian/Ubuntu (apt)

curl -fsSL https://nficano.github.io/debaser/public.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/debaser-archive-keyring.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/debaser-archive-keyring.gpg] https://nficano.github.io/debaser/apt stable main" | sudo tee /etc/apt/sources.list.d/debaser.list >/dev/null
sudo apt update
sudo apt install debaser

RHEL/Fedora (dnf)

sudo tee /etc/yum.repos.d/debaser.repo >/dev/null <<'EOF'
[debaser]
name=debaser
baseurl=https://nficano.github.io/debaser/rpm
enabled=1
repo_gpgcheck=1
gpgcheck=0
gpgkey=https://nficano.github.io/debaser/public.gpg
EOF

sudo dnf install debaser

Rust (cargo)

From crates.io (once published):

cargo install debaser --locked

From source:

cargo install --path .

Manual download (tar.gz / zip)

Download a release asset from GitHub Releases, verify SHA256SUMS + SHA256SUMS.sig, then extract and place debaser on your PATH.

GitHub Actions

Fastest option (uses a prebuilt GitHub Release asset):

- name: Install debaser
  shell: bash
  run: |
    set -euo pipefail
    repo="nficano/debaser"
    version="$(curl -fsSL "https://api.github.com/repos/${repo}/releases/latest" | python3 -c 'import json,sys; print(json.load(sys.stdin)["tag_name"])')"
    target="x86_64-unknown-linux-gnu"
    asset="debaser-${version}-${target}.tar.gz"
    base="https://github.com/${repo}/releases/download/${version}"
    curl -fsSL "$base/$asset" -o "$asset"
    tar -xzf "$asset"
    sudo install -m 0755 "debaser-${version}-${target}/debaser" /usr/local/bin/debaser
    debaser --checksum abcd

Usage

Inside a git repo, debaser uses git rev-parse HEAD as the input:

debaser

Or provide an explicit checksum:

debaser --checksum abcd
# loony-lionfish

Library usage

Add as a dependency (via a path, git, or a published version):

debaser = { path = "../debaser" }

Generate names directly:

let name = debaser::generate_from_checksum(Some("abcd"))?;
assert_eq!(name, "loony-lionfish");

How it works

• Keeps only hexadecimal characters from the input and uses the first 4 as a seed.
• The first byte selects an adjective; the second selects a noun.
• Nouns are biased to start with the same letter as the adjective.

Release notes

Releases are cut via the Makefile and published via GitHub Actions (with generated notes and attached binaries / packages / repos).

make release

This bumps the Cargo.toml version (patch by default), tags v<version>, and pushes it.

Options:

# bump minor/major instead of patch
make release BUMP=minor
make release BUMP=major

# or set an explicit version
make release VERSION=1.2.3

This will:

• Generate a human-friendly release name by running debaser
• Commit any staged/working changes with Release v<version> (<name>) (no-op if there’s nothing to commit)
• Create an annotated git tag (v<version>) and push main + the tag to GitHub

Development

cargo test
