Arweave Name Token process on AO

This repository contains the source code used for Arweave Name Tokens used to resolve ArNS names on AR.IO Gateways. For official documentation on ANT's refer to the ArNS ANT Docs. For official documentation on ArNS refer to the ArNS Docs.

This repository provides two flavours of ANT process module, AOS and a custom module.

Setup

Install

First install the npm dependencies

yarn

Then install the ao cli - read the docs here Below is latest version as of writing, refer to the docs for the latest version.

curl -L https://arweave.net/iVthglhSN7G9LuJSU_h5Wy_lcEa0RE4VQmrtoBMj7Bw | bash

You may need to follow the instructions in the cli to add the program to your PATH.

Testing

To test the module, you can use the following command to run busted

busted .

Building the AOS code

Build

This bundles the ant-aos code and outputs it to dist folder. This can then be used to send to the Eval method on AOS to load the ANT source code.

yarn aos:build

Publish

Ensure that in the tools directory you place you Arweave JWK as key.json

yarn aos:publish

Load

This will load an AOS module into the loader, followed by the bundled aos Lua file to verify that it is a valid build.

yarn aos:load

Spawn

this will spawn an aos process and load the bundled lua code into it.

yarn aos:spawn

This will deploy the bundled lua file to arweave as an L1 transaction, so your wallet will need AR to pay the gas.

Building the custom module

Using the ao-dev-cli.

Build

This will compile the standalone ANT module to wasm, as a file named process.wasm and loads the module in AO Loader to validate the WASM program is valid.

yarn module:build

Publish

Publishes the custom ANT module to arweave - requires you placed your JWK in the tools directory. May require AR in the wallet to pay gas.

yarn module:publish

Load

Loads the module in AO Loader to validate the WASM program is valid.

yarn module:load

Requires module:build to have been called so that process.wasm exists.

Spawn

Spawns a process with the process.wasm file.

yarn module:spawn

   ./configure --with-lua=/usr/local/opt/lua@5.3 --with-lua-include=/usr/local/opt/lua@5.3/include
   make build
   sudo make install

2. Check the installation by running luarocks --version.

3. Check the LuaRocks configuration by running luarocks config | grep LUA

If you ever need to refresh .luarocks, run the following command:

The code is formatted using stylua. To install stylua, run the following command:

cargo install stylua
stylua contract

Testing

To run the tests, execute the following command:

busted .

To see the test coverage, run the following command:

luacov --reporter html && open luacov-html/index.html
