The pcl (Phylax Credible Layer) CLI is a command-line tool for interacting with the Phylax Credible Layer.

​
Installation

The fastest and easiest way to install pcl is using Brew:

brew tap phylaxsystems/pcl
brew install phylax

This will install the pcl binary.

​
Option 2: Install with Cargo

Another convenient way to install pcl is using Cargo. It does require a couple of pre-requisites though:

  • Rust Nightly (version 1.80 or later)
  • Git
cargo +nightly install --git https://github.com/phylaxsystems/pcl --locked

This will install the pcl binary in your Cargo installation directory (typically ~/.cargo/bin on Unix-like systems). Make sure this directory is in your PATH.

​
Option 3: Build from Source

This option is recommended if you want more control over the build process or prefer to build from source.

Prerequisites:

  • Rust Nightly (version 1.80 or later)
  • Git

  1. Clone the repository:

    git clone https://github.com/phylaxsystems/pcl
cd pcl

  2. Build the CLI:

    make build

  3. The compiled binary will be available in the target/release directory.

  4. (Optional) Add the binary to your PATH for easier access:

    # System-wide installation (requires admin privileges)
cp target/release/pcl /usr/local/bin/

# Or for a user-local installation
cp target/release/pcl ~/.local/bin/

    You can place the binary in any directory that’s in your PATH. Choose a location that works best for your system configuration.

    Alternatively, you can create an alias in your shell configuration file (like .bashrc, .zshrc, etc.) that points to the absolute path of the binary:

    # Add to your shell config file
alias pcl="/path/to/pcl/target/release/pcl"

​
Verifying Installation

To verify that pcl is installed correctly, run:

pcl --version

You should see the version number of the installed pcl CLI.

Next Steps

Now that you have pcl installed, you can learn how to get started with the Credible Layer.
