# Metaplex Token Authorization Rules
A program that provides the ability to create and execute rules to restrict common token operations such as transferring and selling.

Read the official documentation [here](https://developers.metaplex.com/token-auth-rules).

## Overview
Authorization rules are variants of a `Rule` enum that implements a `validate()` function.

There are **Primitive Rules** and **Composed Rules** that are created by combining of one or more primitive rules.

**Primitive Rules** store any accounts or data needed for evaluation, and at runtime will produce a true or false output based on accounts and a well-defined `Payload` that are passed into the `validate()` function.

**Composed Rules** return a true or false based on whether any or all of the primitive rules return true. Composed rules can then be combined into higher-level composed rules that implement more complex boolean logic. Because of the recursive definition of the `Rule` enum, calling `validate()` on a top-level composed rule will start at the top and validate at every level, down to the component primitive rules.

## Getting Started

The packages below can be used to interact with Token Authorization Rules (Token Auth Rules) program.

### TypeScript
```sh
npm install @metaplex-foundation/mpl-token-auth-rules
```

[See typedoc documentation](https://mpl-token-auth-rules-js-docs.vercel.app/).

### Rust
```sh
cargo add mpl-token-auth-rules
```

[See crate documentation](https://docs.rs/mpl-token-auth-rules/latest/mpl_token_auth_rules/).

## Building

From the root directory of the repository:

- Install the required packages:
```sh
pnpm install
```

- Build the program:
```sh
pnpm programs:build
```

This will create the program binary at `/programs/.bin`

## Testing

Token Auth Rules includes three sets of tests: BPF, TypeScript for the JS Client, and Legacy Typescript for the Solita-based JS Client.

### BPF

From the root directory of the repository:
```sh
pnpm programs:test
```

### TypeScript

From the root directory of the repository:
```sh
pnpm validator
```

This will start a local validator using [Amman](https://github.com/metaplex-foundation/amman).

After starting the validator, go to the folder `/clients/js` and run:
```sh
pnpm install
```

This will install the required packages for the tests. Then, run:
```sh
pnpm build && pnpm test
```

### Legacy Typescript

Follow all the same steps as for the TypeScript tests above, including starting the validator in the root directory, but for building and running the tests, navigate to the folder `/clients/js-solita`.

## CLI

The folder `cli` contains a typescript CLI to manage rule set revisions:
```
Usage: auth [options] [command]

CLI for managing RuleSet revisions.

Options:
-V, --version output the version number
-h, --help display help for command

Commands:
create [options] creates a new rule set revision
convert [options] converts a rule set revision from V1 to V2
print [options] prints the latest rule set revision as a JSON object
help [command] display help for command
```

To start the CLI, navigate to the folder `./cli` and run
```
$ yarn install
```

Then, the CLI can be used as
```
$ yarn start
```

The folder `./examples` contain several examples of rule sets. You will need to replace the `owner` pubkey value with the pubkey used to run the CLI.

> Note that you need to first build the JS SDK.
