run

Three tutorials provide accompanying code that can be run as discussed in their respective README files:

• 1-pkgs-make (a shell program)
• 2-haskell
• 2-python

These programs are simple and just output a message to the terminal.

There are four “run-” scripts in this directory that you can run if you have Nix installed. Each takes as a single argument either “shell”, “haskell”, or “python” to call the respective tutorial.

Here's a description of the four scripts:

• run-native: runs the program with Nix alone (no Docker involved)

• run-docker-image: builds a Docker image with Nix and runs it with Docker

• run-docker-tarball: builds tarball with Nix which is built into a Docker image and run with Docker

• run-licences: prints a license report with Nix alone (no Docker involved)

If you don't have Nix installed locally, we can do the Nix work within a Nix-imaged Docker container. Just pass the command you want to run as arguments to the provided docker-nix script. For instance:

./docker-nix run-docker-image haskell

We tried to keep the code clean, so you may find that you can pick up a lot from reading these scripts, the code in the tutorials, and the Pkgs-make code.
