How to use this package set


This project requires that you have at least:

  • Linux/OSX. I do not support Windows. You will probably be able to do everything using WSL, but I will not support any issues (you will probably barely run into any with WSL). I also assume your distro is from the last decade, any distributions older than 2008 are not supported.
  • Dhall-Haskell and Dhall-JSON installed. You can probably install them from Nix or from source.
  • Psc-Package installed, with the release binary in your PATH in some way.
  • jq installed.

How to generate the package set after editing Dhall files

First, test that you can actually run make:

> make
formatted dhall files
generated to packages.json
validated packages' dependencies

This is how you format Dhall files in the project, generate the packages.json that needs to be checked in, and validate that all dependencies declared in package definitions are at least valid. Unless you plan to consume only the packages.dhall file in your repository, you must check in packages.json.

To actually use your new package set, you must create a new git tag and push it to your fork of spacchetti. Then set your package set in your project repository accordingly, per EXAMPLE:

  "name": "EXAMPLE",
  "set": "160618", // GIT TAG NAME
  "source": "", // PACKAGE SET REPO URL
  "depends": [

When you set this up correctly, you will see that running psc-package install will create the file .psc-package/{GIT TAG NAME HERE}/.set/packages.json.

Testing changes to package set

To set up a test project, run make setup. Then you can test individual packages with psc-package verify PACKAGE.
