Welcome to your new Dhall package-set!

Below are instructions for how to edit this file for most use
cases, so that you don't need to know Dhall to use it.

## Warning: Don't Move This Top-Level Comment!

Due to how `dhall format` currently works, this comment's
instructions cannot appear near corresponding sections below
because `dhall format` will delete the comment. However,
it will not delete a top-level comment like this one.

## Use Cases

Most will want to do one or both of these options:
1. Override/Patch a package's dependency
2. Add a package not already in the default package set

This file will continue to work whether you use one or both options.
Instructions for each option are explained below.

### Overriding/Patching a package

Purpose:
- Change a package's dependency to a newer/older release than the
default package set's release
- Use your own modified version of some dependency that may
include new API, changed API, removed API by
using your custom git repo of the library rather than
the package set's repo

Syntax:
Replace the overrides' "{=}" (an empty record) with the following idea
The "//" means "merge these two records and
when they have the same value, use the one on the right:"
-------------------------------
let override =
{ packageName =
upstream.packageName // { updateEntity1 = "new value", updateEntity2 = "new value" }
, packageName =
upstream.packageName // { version = "v4.0.0" }
, packageName =
upstream.packageName // { repo = "https://www.example.com/path/to/new/repo.git" }
}
-------------------------------

Example:
-------------------------------
let overrides =
{ halogen =
upstream.halogen // { version = "master" }
, halogen-vdom =
upstream.halogen-vdom // { version = "v4.0.0" }
}
-------------------------------

### Additions

Purpose:
- Add packages that aren't already included in the default package set

Syntax:
Replace the additions' "{=}" (an empty record) with the following idea:
-------------------------------
let additions =
{ package-name =
{ dependencies =
[ "dependency1"
, "dependency2"
]
, repo =
"https://example.com/path/to/git/repo.git"
, version =
"tag ('v4.0.0') or branch ('master')"
}
, package-name =
{ dependencies =
[ "dependency1"
, "dependency2"
]
, repo =
"https://example.com/path/to/git/repo.git"
, version =
"tag ('v4.0.0') or branch ('master')"
}
, etc.
}
-------------------------------

Example:
-------------------------------
let additions =
{ benchotron =
{ dependencies =
[ "arrays"
, "exists"
, "profunctor"
, "strings"
, "quickcheck"
, "lcg"
, "transformers"
, "foldable-traversable"
, "exceptions"
, "node-fs"
, "node-buffer"
, "node-readline"
, "datetime"
, "now"
]
, repo =
"https://github.com/hdgarrood/purescript-benchotron.git"
, version =
"v7.0.0"
}
}
-------------------------------

https://github.com/purescript/package-sets/releases/download/psc-0.13.6-20200226/packages.dhall sha256:3a52562e05b31a7b51d12d5b228ccbe567c527781a88e9028ab42374ab55c0f1

This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).

## Available Scripts

In the project directory, you can run:

### `npm start`

Runs the app in the development mode.<br />
Open [http://localhost:3000](http://localhost:3000) to view it in the browser.

The page will reload if you make edits.<br />
You will also see any lint errors in the console.

### `npm test`

Launches the test runner in the interactive watch mode.<br />
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.

### `npm run build`

Builds the app for production to the `build` folder.<br />
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.<br />
Your app is ready to be deployed!

See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.

### `npm run eject`

**Note: this is a one-way operation. Once you `eject`, you can’t go back!**

If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

## Learn More

You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).

To learn React, check out the [React documentation](https://reactjs.org/).
