Setup on Linux

This page gives the first step of the setup on Linux: the dependencies. The other steps for Linux are coming. setup-macos.md gives all the steps for macOS.

The dependencies

What it does. These commands install every required tool that the harness calls, on Debian or Ubuntu. apt-get installs the tools that the distribution packages. actionlint, fatou and Julia come from their own installers, which their projects give. Dependencies lists each tool, its minimum version and what the harness uses it for.

sudo apt-get update
sudo apt-get install python3 git gh gitleaks nodejs npm shellcheck coreutils rsync curl
mkdir -p ~/.local/bin
bash <(curl -fsSL https://raw.githubusercontent.com/rhysd/actionlint/main/scripts/download-actionlint.bash) latest ~/.local/bin
curl --proto '=https' --tlsv1.2 -sSf https://fatou.dev/install | sh
curl -fsSL https://install.julialang.org | sh

Without Julia code, skip the fatou line: fatou checks Julia code only. You still need Julia, because the first install of the harness runs it once.

The installers of actionlint and fatou put the program into a directory in your home directory; the actionlint line uses ~/.local/bin. That directory must be on the PATH. The installer of juliaup asks you to confirm its settings; with its default settings, it installs juliaup and the current Julia release, and adds them to the PATH in your shell's start file. Open a new terminal after it.

Why. Each tool has the job that Dependencies describes. A release of a distribution can package an older version than the minimum that Dependencies gives, for example of Python, Node.js or gitleaks. Then install that tool from its own site.

Check. Each command prints its version. Compare each version with the minimum of Dependencies.

python3 --version
node --version
gitleaks version
actionlint --version
julia --version
