Installation

alint ships as a single native executable with no language runtime, no JVM, and nothing else to install. Pick whichever path matches your environment.

Homebrew (macOS + Linuxbrew)

brew tap asamarts/alint
brew install alint

The recommended path on macOS and Linux. The asamarts/homebrew-alint tap is auto-updated on every release; the formula resolves the matching pre-built tarball for your platform, verifies its SHA-256, and installs to the Homebrew cellar.

install.sh (Linux + macOS + Windows tarballs)

curl -sSL https://alint.org/install.sh | bash

Detects platform (Linux / macOS, x86_64 / aarch64), downloads the matching tarball from GitHub Releases, verifies its SHA-256, and installs to $INSTALL_DIR (default ~/.local/bin). Windows users download the Windows tarball from the Releases page directly.

Supply-chain note: the installer verifies the SHA-256 of the release tarball it downloads, but the script itself is fetched from the main branch (alint.org/install.sh redirects there). To pin the installer too, point curl at a release tag instead of main (for example https://raw.githubusercontent.com/asamarts/alint/v0.14.2/install.sh), or download it from the Releases page and review it before running.

Docker

A distroless multi-arch image (linux/amd64, linux/arm64) is published to ghcr.io on each release:

# Lint the current directory:
docker run --rm -v "$PWD:/repo" ghcr.io/asamarts/alint:latest

# Pin to an exact version:
docker run --rm -v "$PWD:/repo" ghcr.io/asamarts/alint:v0.14.2 check

The image runs as the distroless nonroot user (UID 65532); host files must be world-readable. To apply fixes and preserve host ownership, pass -u:

docker run --rm -u $(id -u):$(id -g) -v "$PWD:/repo" ghcr.io/asamarts/alint:latest fix

Also published: :<major>.<minor> (e.g. :0.10) and the raw git tag (:v0.14.2).

crates.io

cargo install alint

Builds from source against the current stable Rust toolchain. Requires cargo already on $PATH.

From source

git clone https://github.com/asamarts/alint
cd alint
cargo build --release -p alint
./target/release/alint --help

Useful when you want to track main between releases or are contributing patches.

Verify the install

alint --version

Should print alint <version> matching the channel you installed from.
