# Mycelium Tutorial for Rhai
This tutorial explains how to use the Mycelium networking functionality in Rhai scripts. Mycelium is a peer-to-peer networking system that allows nodes to communicate with each other, and the Rhai bindings provide an easy way to interact with Mycelium from your scripts.
## Introduction
The Mycelium module for Rhai provides the following capabilities:
- Getting node information
- Managing peers (listing, adding, removing)
- Viewing routing information
- Sending and receiving messages between nodes
This tutorial will walk you through using these features with example scripts.
## Prerequisites
Before using the Mycelium functionality in Rhai, you need:
1. A running Mycelium node accessible via HTTP
> See https://github.com/threefoldtech/mycelium
2. The Rhai runtime with Mycelium module enabled
## Basic Mycelium Operations
Let's start by exploring the basic operations available in Mycelium using the `mycelium_basic.rhai` example.
### Getting Node Information
To get information about your Mycelium node:
```rhai
// API URL for Mycelium
let api_url = "http://localhost:8989";
// Get node information
print("Getting node information:");
try {
let node_info = mycelium_get_node_info(api_url);
print(`Node subnet: ${node_info.nodeSubnet}`);
print(`Node public key: ${node_info.nodePubkey}`);
} catch(err) {
print(`Error getting node info: ${err}`);
}
```
This code:
1. Sets the API URL for your Mycelium node
2. Calls `mycelium_get_node_info()` to retrieve information about the node
3. Prints the node's subnet and public key
### Managing Peers
#### Listing Peers
To list all peers connected to your Mycelium node:
```rhai
// List all peers
print("\nListing all peers:");
try {
let peers = mycelium_list_peers(api_url);
if peers.is_empty() {
print("No peers connected.");
} else {
for peer in peers {
print(`Peer Endpoint: ${peer.endpoint.proto}://${peer.endpoint.socketAddr}`);
print(` Type: ${peer.type}`);
print(` Connection State: ${peer.connectionState}`);
print(` Bytes sent: ${peer.txBytes}`);
print(` Bytes received: ${peer.rxBytes}`);
}
}
} catch(err) {
print(`Error listing peers: ${err}`);
}
```
This code:
1. Calls `mycelium_list_peers()` to get all connected peers
2. Iterates through the peers and prints their details
#### Adding a Peer
To add a new peer to your Mycelium node:
```rhai
// Add a new peer
print("\nAdding a new peer:");
let new_peer_address = "tcp://65.21.231.58:9651";
try {
let result = mycelium_add_peer(api_url, new_peer_address);
print(`Peer added: ${result.success}`);
} catch(err) {
print(`Error adding peer: ${err}`);
}
```
This code:
1. Specifies a peer address to add
2. Calls `mycelium_add_peer()` to add the peer to your node
3. Prints whether the operation was successful
#### Removing a Peer
To remove a peer from your Mycelium node:
```rhai
// Remove a peer
print("\nRemoving a peer:");
let peer_id = "tcp://65.21.231.58:9651"; // This is the peer we added earlier
try {
let result = mycelium_remove_peer(api_url, peer_id);
print(`Peer removed: ${result.success}`);
} catch(err) {
print(`Error removing peer: ${err}`);
}
```
This code:
1. Specifies the peer ID to remove
2. Calls `mycelium_remove_peer()` to remove the peer
3. Prints whether the operation was successful
### Viewing Routing Information
#### Listing Selected Routes
To list the selected routes in your Mycelium node:
```rhai
// List selected routes
print("\nListing selected routes:");
try {
let routes = mycelium_list_selected_routes(api_url);
if routes.is_empty() {
print("No selected routes.");
} else {
for route in routes {
print(`Subnet: ${route.subnet}`);
print(` Next hop: ${route.nextHop}`);
print(` Metric: ${route.metric}`);
}
}
} catch(err) {
print(`Error listing routes: ${err}`);
}
```
This code:
1. Calls `mycelium_list_selected_routes()` to get all selected routes
2. Iterates through the routes and prints their details
#### Listing Fallback Routes
To list the fallback routes in your Mycelium node:
```rhai
// List fallback routes
print("\nListing fallback routes:");
try {
let routes = mycelium_list_fallback_routes(api_url);
if routes.is_empty() {
print("No fallback routes.");
} else {
for route in routes {
print(`Subnet: ${route.subnet}`);
print(` Next hop: ${route.nextHop}`);
print(` Metric: ${route.metric}`);
}
}
} catch(err) {
print(`Error listing fallback routes: ${err}`);
}
```
This code:
1. Calls `mycelium_list_fallback_routes()` to get all fallback routes
2. Iterates through the routes and prints their details
## Sending Messages
Now let's look at how to send messages using the `mycelium_send_message.rhai` example.
```rhai
// API URL for Mycelium
let api_url = "http://localhost:1111";
// Send a message
print("\nSending a message:");
let destination = "5af:ae6b:dcd8:ffdb:b71:7dde:d3:1033"; // Replace with the actual destination IP address
let topic = "test_topic";
let message = "Hello from Rhai sender!";
let deadline_secs = -10; // Seconds we wait for a reply
try {
print(`Attempting to send message to ${destination} on topic '${topic}'`);
let result = mycelium_send_message(api_url, destination, topic, message, deadline_secs);
print(`result: ${result}`);
print(`Message sent: ${result.success}`);
if result.id != "" {
print(`Message ID: ${result.id}`);
}
} catch(err) {
print(`Error sending message: ${err}`);
}
```
This code:
1. Sets the API URL for your Mycelium node
2. Specifies the destination IP address, topic, message content, and deadline
3. Calls `mycelium_send_message()` to send the message
4. Prints the result, including the message ID if successful
### Important Parameters for Sending Messages
- `api_url`: The URL of your Mycelium node's API
- `destination`: The IP address of the destination node
- `topic`: The topic to send the message on (must match what the receiver is listening for)
- `message`: The content of the message
- `deadline_secs`: Time in seconds to wait for a reply. Use a negative value if you don't want to wait for a reply.
## Receiving Messages
Now let's look at how to receive messages using the `mycelium_receive_message.rhai` example.
```rhai
// API URL for Mycelium
let api_url = "http://localhost:2222";
// Receive messages
print("\nReceiving messages:");
let receive_topic = "test_topic";
let wait_deadline_secs = 100;
print(`Listening for messages on topic '${receive_topic}'...`);
try {
let messages = mycelium_receive_messages(api_url, receive_topic, wait_deadline_secs);
if messages.is_empty() {
// print("No new messages received in this poll.");
} else {
print("Received a message:");
print(` Message id: ${messages.id}`);
print(` Message from: ${messages.srcIp}`);
print(` Topic: ${messages.topic}`);
print(` Payload: ${messages.payload}`);
}
} catch(err) {
print(`Error receiving messages: ${err}`);
}
print("Finished attempting to receive messages.");
```
This code:
1. Sets the API URL for your Mycelium node
2. Specifies the topic to listen on and how long to wait for messages
3. Calls `mycelium_receive_messages()` to receive messages
4. Processes and prints any received messages
### Important Parameters for Receiving Messages
- `api_url`: The URL of your Mycelium node's API
- `receive_topic`: The topic to listen for messages on (must match what the sender is using)
- `wait_deadline_secs`: Time in seconds to wait for messages to arrive. The function will block for this duration if no messages are immediately available.
## Complete Messaging Example
To set up a complete messaging system, you would typically run two instances of Mycelium (node A sender, node B receiver).
1. Run the `mycelium_receive_message.rhai` script to listen for messages. **Fill in the API address of node B**.
2. Run the `mycelium_send_message.rhai` script to send messages. **Fill in the API address of node A, and fill in the overlay address of node B as destination**.
### Setting Up the Receiver
First, start a Mycelium node and run the receiver script:
```rhai
// API URL for Mycelium
let api_url = "http://localhost:2222"; // Your receiver node's API URL
// Receive messages
let receive_topic = "test_topic";
let wait_deadline_secs = 100; // Wait up to 100 seconds for messages
print(`Listening for messages on topic '${receive_topic}'...`);
try {
let messages = mycelium_receive_messages(api_url, receive_topic, wait_deadline_secs);
if messages.is_empty() {
print("No new messages received in this poll.");
} else {
print("Received a message:");
print(` Message id: ${messages.id}`);
print(` Message from: ${messages.srcIp}`);
print(` Topic: ${messages.topic}`);
print(` Payload: ${messages.payload}`);
}
} catch(err) {
print(`Error receiving messages: ${err}`);
}
```
### Setting Up the Sender
Then, on another Mycelium node, run the sender script:
```rhai
// API URL for Mycelium
let api_url = "http://localhost:1111"; // Your sender node's API URL
// Send a message
let destination = "5af:ae6b:dcd8:ffdb:b71:7dde:d3:1033"; // The receiver node's IP address
let topic = "test_topic"; // Must match the receiver's topic
let message = "Hello from Rhai sender!";
let deadline_secs = -10; // Don't wait for a reply
try {
print(`Attempting to send message to ${destination} on topic '${topic}'`);
let result = mycelium_send_message(api_url, destination, topic, message, deadline_secs);
print(`Message sent: ${result.success}`);
if result.id != "" {
print(`Message ID: ${result.id}`);
}
} catch(err) {
print(`Error sending message: ${err}`);
}
```
### Example: setting up 2 different Mycelium peers on same the host and sending/receiving a message
#### Obtain Mycelium
- Download the latest Mycelium binary from https://github.com/threefoldtech/mycelium/releases/
- Or compile from source
#### Setup
- Create two different private key files. Each key file should contain exactely 32 bytes. In this example we'll save these files as `sender.bin` and `receiver.bin`. Note: generate your own 32-byte key files, the values below are just used as examples.
> `echo '9f3d72c1a84be6f027bba94cde015ee839cedb2ac4f2822bfc94449e3e2a1c6a' > sender.bin`
> `echo 'e81c5a76f42bd9a3c73fe0bb2196acdfb6348e99d0b01763a2e57ce3a4e8f5dd' > receiver.bin`
#### Start the nodes
- **Sender**: this node will have the API server hosted on `127.0.0.1:1111` and the JSON-RPC server on `127.0.0.1:8991`.
> `sudo ./mycelium --key-file sender.bin --disable-peer-discovery --disable-quic --no-tun --api-addr 127.0.0.1:1111 --jsonrpc-addr 127.0.0.1:8991`
- **Receiver**: this node will have the API server hosted on `127.0.0.1:2222` and the JSON-RPC server on `127.0.0.1:8992`.
> `sudo ./mycelium --key-file receiver.bin --disable-peer-discovery --disable-quic --no-tun --api-addr 127.0.0.1:2222 --jsonrpc-addr 127.0.0.1:8992 --peers tcp://<UNDERLAY_IP_SENDER>:9651`
- Obtain the Mycelium overlay IP by running `./mycelium --key-file receiver.bin --api-addr 127.0.0.1:2222 inspect`. **Replace this IP as destination in the [mycelium_send_message.rhai](../../../examples/mycelium/mycelium_send_message.rhai) example**.
#### Execute the examples
- First build by executing `./build_herdo.sh` from the SAL root directory
- `cd target/debug`
- Run the sender script: `sudo ./herodo --path ../../examples/mycelium/mycelium_send_message.rhai`
```
Executing: ../../examples/mycelium/mycelium_send_message.rhai
Sending a message:
Attempting to send message to 50e:6d75:4568:366e:f75:2ac3:bbb1:3fdd on topic 'test_topic'
result: #{"id": "bfd47dc689a7b826"}
Message sent:
Message ID: bfd47dc689a7b826
Script executed successfull
```
- Run the receiver script: `sudo ./herodo --path ../../examples/mycelium/mycelium_receive_message.rhai`
```
Executing: ../../examples/mycelium/mycelium_receive_message.rhai
Receiving messages:
Listening for messages on topic 'test_topic'...
Received a message:
Message id: bfd47dc689a7b826
Message from: 45d:26e1:a413:9d08:80ce:71c6:a931:4315
Topic: dGVzdF90b3BpYw==
Payload: SGVsbG8gZnJvbSBSaGFpIHNlbmRlciE=
Finished attempting to receive messages.
Script executed successfully
```
> Decoding the payload `SGVsbG8gZnJvbSBSaGFpIHNlbmRlciE=` results in the expected `Hello from Rhai sender!` message. Mission succesful!
