Install Spex - Spex

Installation

There are two main ways of installing Spex, either from pre-compiled binaries or by building the binaries yourself from source.

From pre-compiled binary

The easiest way to get the right pre-compiled binaries for your platform is to use the spexup installer as follows.

Automatic

 curl --proto '=https' --tlsv1.2 -sSf \
   https://raw.githubusercontent.com/spex-lang/spexup/refs/heads/main/spexup \
 | sh

What does this do? It automates the manual steps below.

Manual

If you don't like to pipe scripts into a shell (fair enough), you can manually install the binaries as follows:

  1. Go to releases;
  2. Click on "Assets" for the latest release;
  3. Download the binaries for your platform and put them into your PATH.

From source

When you build from source you'll need the GHC Haskell compiler and the Cabal package system.

With Nix

If you got the Nix package manager installed then the shell.nix file provides all dependencies, and you can simply type:

git clone https://github.com/spex-lang/spex.git
cd spex
nix-shell
cabal build all
cabal install spex spex-demo-petstore

Without Nix

If you don't use Nix, then the easiest way to get the right Haskell dependencies is to first install ghcup, the Haskell installer, and then issue:

git clone https://github.com/spex-lang/spex.git
cd spex
ghcup install cabal 3.12.1.0 --set
ghcup install ghc 9.8.4 --set
cabal build all
cabal install spex spex-demo-petstore
