AO Dev-Cli 0.1

The AO dev-cli is a tool that is used to build ao wasm modules, the first versions of the tool only supported lua as the embedded language or c based module. With this release developers now can add any pure c or cpp module to their wasm builds. This opens the door for many different innovations from indexers to languages.

Install

Requirements

Docker is required: https://docker.com

curl -L https://install_ao.g8way.io | sh

Start a project

ao init [project-name]

Build a project

cd [project-name]
ao build

Deploy a project

Requirements

You will need an arweave keyfile, you can create a local one using this command npx -y @permaweb/wallet > wallet.json

ao publish -w [path_to_wallet] [path_to_wasm]

Configuration

To customize your build process, create a config.yml file in the root directory of your project. This file will modify your settings during the build.

Configuration Options:

• preset: Selects default values for stack_size, initial_memory, and maximum_memory. For available presets, see Config Presets. (Default: md)

• stack_size: Specifies the stack size, overriding the value from the preset. Must be a multiple of 64. (Default: 32MB)

• initial_memory: Defines the initial memory size, overriding the preset value. Must be larger than stack_size and a multiple of 64. (Default: 48MB)

• maximum_memory: Sets the maximum memory size, overriding the preset value. Must be larger than stack_size and a multiple of 64. (Default: 256MB)

• extra_compile_args: Provides additional compilation commands for emcc. (Default: [])

• keep_js: By default, the generated .js file is deleted since AO Loader uses predefined versions. Set this to true if you need to retain the .js file. (Default: false)

Libraries

Starting with version 0.1.3, you can integrate external libraries into your project. To do this, follow these guidelines:

Adding Libraries

1. Create a libs Directory: At the root of your project, create a directory named /libs. This is where you'll place your library files.

2. Place Your Library Files: Copy or move your compiled library files (e.g., .a, .so, .o, .dylib, etc.) into the /libs directory.

   Note

   Ensure that all library files are compiled using emcc to ensure compatibility with your project.

Example Directory Structure

│
├── libs/
│ ├── libexample.a
│ ├── libanother.so
│ └── libmore.o
│
├── process.lua
├── ao.lua
│
└── config.yml

Using Libraries in Your Code

After adding the library files to the /libs directory, you need to link against these libraries in your project. This often involves specifying the library path and names in your build scripts or configuration files. For example:

• For C/C++ Projects: You can just include any header files placed in the libs folder as the libs with be automatically built into your module.
• For Lua Projects: Depending on how your build your libraries and if you compiled them with Lua bindings you can just require the libs in your lua files. markdown = require('markdown')

Lua Build Example

To create and build a Lua project, follow these steps:

ao init -l lua [project-name]
cd [project-name]
ao build

C Build Example

To create and build a C project, follow these steps:

ao init -l c [project-name]
cd [project-name]
ao build
