Setup

Building components

# Clone the repo.

git clone git@github.com:uqbar-dao/nectar.git

# Configure dependency retrieval from GitHub
mkdir .cargo
echo "net.git-fetch-with-cli = true" > .cargo/config

# Get some stuff so we can build Wasm.

cd nectar
cargo install wasm-tools
rustup install nightly
rustup target add wasm32-wasi
rustup target add wasm32-wasi --toolchain nightly
cargo install cargo-wasi

# Build the runtime, along with a number of booted-at-startup WASM modules including terminal and key_value
# OPTIONAL: --release flag

cargo +nightly build --release

Boot

Get an eth-sepolia-rpc API key and pass that as an argument. You can get one for free at alchemy.com.

Make sure not to use the same home directory for two nodes at once! You can use any name for the home directory: here we just use home. The -- here separates cargo arguments from binary arguments.

TODO: document feature flags --simulation-mode

cargo +nightly run --release -- home --rpc wss://eth-sepolia.g.alchemy.com/v2/<your-api-key>

On boot you will be prompted to navigate to localhost:8080. Make sure your ETH wallet is connected to the Sepolia test network. Login should be straightforward, just submit the transactions and follow the flow. If you want to register a new ID you will either need Sepolia testnet tokens or an invite code.

Terminal syntax

• CTRL+C or CTRL+D to gracefully shutdown node

• CTRL+V to toggle through verbose modes (0-3, 0 is default and lowest verbosity)

• CTRL+J to toggle debug mode

• CTRL+S to step through events in debug mode

• CTRL+L to toggle logging mode, which writes all terminal output to the .terminal_log file. Off by default, this will write all events and verbose prints with timestamps.

• CTRL+A to jump to beginning of input

• CTRL+E to jump to end of input

• UpArrow/DownArrow or CTRL+P/CTRL+N to move up and down through command history

• CTRL+R to search history, CTRL+R again to toggle through search results, CTRL+G to cancel search

• /message <address> <json>: send an inter-process message.

  is formatted as @<process_id>. <process_id> is formatted as <process_name>:<package_name>:<publisher_node>.
  • Example: /message our@net:sys:nectar diagnostics
  • our will always be interpolated by the system as your node's name
  • Can also use /m for same command: /m our@net:sys:nectar diagnostics

• /app <address>: set the terminal to a mode where all messages go to a specific app. To clear this selection, use /app clear or simply /app. This is useful for apps that have a command line interface.

  • Example: /app our@net:sys:nectar, then /m diagnostics
  • Can also use /a for same command: /a our@net:sys:nectar
  • Example of sending many messages:
    • /a ben.nec@net:sys:nectar
    • /m hey there
    • /m how are you?
    • /a (to exit app mode)

• /hi <name> <string>: send a text message to another node's command line.

  • Example: /hi ben.nec hello world

Example usage

Download and install an app:

/m our@main:app_store:nectar {"Download": {"package": {"package_name": "<pkg>", "publisher_node": "<node>"}, "install_from": "<node>"}}
/m our@main:app_store:nectar {"Install": {"package_name": "<pkg>", "publisher_node": "<node>"}}
