pkgx Backend experimental

The pkgx backend installs packages from the pkgx pantry without shelling out to the pkgx CLI. mise resolves pantry metadata, downloads pkgx bottles from dist.pkgx.dev, verifies bottle checksums when available, and writes wrapper scripts that set the package runtime environment.

This backend is experimental. Enable it with:

mise settings experimental=true

Or set MISE_EXPERIMENTAL=1 for a single shell/session.

Usage

Install a pkgx package by its pantry project name:

mise use pkgx:stedolan.github.io/jq@1.7.1
jq --version

The version will be set in mise.toml with the following format:

[tools]
"pkgx:stedolan.github.io/jq" = "1.7.1"

Lockfiles

The pkgx backend supports mise.lock. Locking records the main bottle URL and checksum on the tool entry, and records transitive pkgx dependencies in the shared [pkgx-packages] lockfile section.

mise lock
mise install --locked

When --locked is enabled, mise requires a lockfile URL for the current platform and will fail instead of doing a live pantry resolution if the lockfile is missing or incomplete.

Notes

• This backend currently supports platforms that pkgx publishes bottles for.
• Version requirements are resolved from pkgx pantry metadata using npm-style semver ranges.
• Runtime environment from pantry manifests is applied through generated wrappers.
