Seal

Seal is a release-management tool, written in Rust. It keeps version updates, changelog generation, release branches, commits, and release notes in one CLI.

Warning

Seal is in alpha and is not yet ready for production use. Expect missing features and breaking changes.

Features

• Update versions in plain-text files, TOML fields, and files selected by glob patterns.
• Preview every file change before applying it, or use --dry-run in automation.
• Create release branches and commits, run pre-commit commands, and push the result.
• Build changelogs from merged GitHub pull requests, grouped by labels.
• Produce JSON release metadata from the latest changelog section.

Installation

Install Seal with the standalone installer for your platform:

# macOS and Linux
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/MatthewMckee4/seal/releases/download/0.0.1-alpha.8/seal-installer.sh | sh

# Windows
powershell -ExecutionPolicy Bypass -c "irm https://github.com/MatthewMckee4/seal/releases/download/0.0.1-alpha.8/seal-installer.ps1 | iex"

Prebuilt archives and checksums are available from the GitHub Releases. Seal is not currently published to crates.io or other package registries.

Getting Started

[release]
current-version = "0.1.0"
version-files = [
    { path = "Cargo.toml", format = "toml", field = "package.version" },
]

Validate the configuration and preview a patch release:

seal validate config
