Spacchetti

Mà, ho comprato una scatola di PureScript!

Dhall-driven package sets, made for forking and modifying easily. Per chi non ha paura di rimboccarsi le maniche (e arrotolare gli spaghetti).

The Raisin Deets

Nobody likes editing JSON. Even fewer actually like figuring out how to resolve conflicts in Git, especially if they aren't used to aborting rebases and digging up commits from reflog. Everyone complains there is no good solution for having your own patches on top of upstream changes, for when you want to add just a few of your own packages or override existing definitions.

Well, now all you have to do is complain that this repo doesn't have enough contributors, commits, maintenance, curation, etc., because those above issues are solved with the usage of Dhall to merge package definitions and Psc-Package verify on CI.

How to consume this package set

Use Spago or Psc-Package.

How files are organized

-- Package type definition
src/Package.dhall

-- function to define packages
src/mkPackage.dhall

-- packages to be included when building package set
src/packages.dhall

-- package "groups" where packages are defined in records
src/groups/[...].dhall

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": "https://github.com/spacchetti/spacchetti.git", // PACKAGE SET REPO URL
  "depends": [
    "console",
    "prelude"
  ]
}

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.

FAQ

How do I use this package set?

Use Spago or Psc-Package.

Can I get additional help?

Open an issue in Spago or ask on FP Slack.

Does ___ in scripts/ mean ____?

No, these are just random scripts that are used to maintain Spacchetti package sets. They are not used by Psc-Package nor are they used by Spago.

Can I use packages from Bower?

You can use anything that is a git repository, which mean every Bower dependency and others. See the local setup docs if you want to locally add them to a project: https://spacchetti.readthedocs.io/en/latest/local-setup.html
