Prebuilt Down

A CLI tool that helps automatically resolve the external prebuilt binary dependencies in your codebases.

Installation

With binstall (recommanded):

cargo binstall prebuilt-down

With cargo (build from source):

cargo install prebuilt-down

Within GitHub Actions:

- uses: cargo-bins/cargo-binstall@main
- run: cargo binstall prebuilt-down --no-confirm

Usage

This will automatically read the prebuilt-down.toml file in the cwd and download prebuilts:

prebuilt-down

Specify the config file:

prebuilt-down --config config/binaries.toml
prebuilt-down -c config/binaries.toml

Specify the platform (prebuilt-down downloads the binary for the current platform by default):

prebuilt-down --platform windows-x64
prebuilt-down -p windows-x64
