ghr

A toolkit for GitHub releases.

Install tools from GitHub releases with one cross-platform command. A single static binary that picks the right asset for your OS and architecture. Supports verifying with minisign, sigstore, GitHub artifact attestations, and checksums. Install it on a GitHub-hosted runner with pipx install ghr-bin.

Usage

ghr list                                          List installed tools
ghr install <spec> [<pubkey>] [<spec> ...]        Install one or more tools from GitHub releases
ghr uninstall <name>                              Remove an installed tool
ghr download <spec> [<pubkey>] [<spec> ...]       Download one or more release assets
ghr path add [--dry-run]                          Add ghr's bin dir to your user PATH
ghr path [bin|tools|cache]                        Show ghr directories
ghr minisign sign <file> [<file> ...]             Sign release artifacts with a minisign key
ghr version                                       Print version and exit
ghr help                                          Print this help and exit

Each <spec> is owner/repo[@tag] (auto-pick asset) or owner/repo/file[@tag] (specific asset). A 56-char RW/RU-prefixed base64 token immediately after a spec is treated as that spec's minisign public key. Run ghr <COMMAND> help to show help for a specific command, e.g. ghr download help.

Examples

# Install the latest release of a tool
ghr install burntsushi/ripgrep

# Install a specific version
# https://github.com/bytecodealliance/wasmtime/releases/tag/v44.0.1
ghr install bytecodealliance/wasmtime@v44.0.1

# Install several tools in one invocation (shared HTTP client + auth)
ghr install burntsushi/ripgrep@15.1.0 sharkdp/fd@v10.2.0

# Install minisign itself, verifying with its minisign public key
ghr install jedisct1/minisign@0.12 RWQf6LRCGA9i53mlYecO4IzT51TGPpvWucNSCh1CBM0QTaLn73Y7GFO3

Install

pipx install ghr-bin
uv tool install ghr-bin
winget install ghr
brew install cataggar/ghr/ghr
curl -fsSL https://raw.githubusercontent.com/cataggar/ghr/main/install.sh | sh
iwr -useb https://raw.githubusercontent.com/cataggar/ghr/main/install.ps1 | iex
ghr install cataggar/ghr RWSbsumpaHb+N3KCEt/EUXQ5y6Kkk8r/zCb5Z4jhEuEX8x2/U5wr5QC0

See doc/README.md for download, install, directories, uninstall, and verification details (including verifying ghr's own releases).

GitHub Actions

For workflows, install several tools in one cached step:

- uses: cataggar/ghr/actions/install@v0.5.1  # pin to the matching ghr release
  with:
    tools: |
      burntsushi/ripgrep@14.1.1
      sharkdp/fd@v10.2.0

The action shares git tags with the ghr CLI — pinning @v0.5.1 pins both the action body and the ghr-bin binary. Pick the latest tag from the releases page.

See actions/install, actions/download, and the Caching in GitHub Actions section for details.

Signing releases

ghr minisign sign produces a minisign .minisig sidecar without an external minisign binary, a key file on disk, or an expect script. The secret key and password come from the environment, so a release job is a single step:

- run: ghr minisign sign hello.wasm -t "tag:${{ github.ref_name }} commit:${GITHUB_SHA}"
  env:
    MINISIGN_SECRET_KEY: ${{ secrets.MINISIGN_SECRET_KEY }}
    MINISIGN_PASSWORD:   ${{ secrets.MINISIGN_PASSWORD }}

Input files are bare positional arguments (each <file> is signed to <file>.minisig). A trusted comment may be given with -t (applied to every input); when omitted it defaults, like minisign, to timestamp:<unix>\tfile:<name>\thashed per file. The secret key must come from MINISIGN_SECRET_KEY and an encrypted key's password from MINISIGN_PASSWORD — there is no key-file flag, and the password is never read from a tty or stdin. Signatures use the prehashed (ED) format and are byte-for-byte identical to minisign -S output. Run ghr minisign sign help for all options.
