### Setup Python Virtual Environment

Source: https://bots.delta.chat/quickstart

Installs and activates a Python virtual environment for isolated dependency management. This is a standard practice for Python projects to avoid conflicts.

```bash
pip install virtualenv
virtualenv .venv
source .venv/bin/activate
```

--------------------------------

### Start Bot CLI

Source: https://bots.delta.chat/quickstart

Ensures that the bot's command-line interface starts and begins processing events when the script is executed directly. This is the entry point for running the bot.

```python
if __name__ == "__main__":
    cli.start()
```

--------------------------------

### Install Delta Chat CLI Dependency

Source: https://bots.delta.chat/quickstart

Installs the 'deltabot-cli' library, which provides a high-level framework for simplifying bot development in Delta Chat. This is a crucial dependency for the bot's functionality.

```bash
pip install deltabot-cli
```

--------------------------------

### Run the Bot

Source: https://bots.delta.chat/quickstart

Starts the Delta Chat bot, making it online and ready to process incoming messages. This command should be run after the bot has been configured and initialized.

```bash
python ./echobot.py serve
```

--------------------------------

### Generate Bot Invite Link

Source: https://bots.delta.chat/quickstart

Generates a unique invitation link for the bot. This link can be shared with users to allow them to start a chat with the bot.

```bash
python ./echobot.py link
```

--------------------------------

### Full Echo Bot Source Code

Source: https://bots.delta.chat/quickstart

The complete Python script for the echo bot, combining all the necessary imports, CLI initialization, event handling, and the starting point. This file can be directly used to create the bot.

```python
from deltabot_cli import BotCli
from deltachat2 import MsgData, events

cli = BotCli("echobot")

@cli.on(events.NewMessage)
def echo(bot, accid, event):
    msg = event.msg
    reply = MsgData(text=msg.text)
    bot.rpc.send_msg(accid, msg.chat_id, reply)

if __name__ == "__main__":
    cli.start()
```

--------------------------------

### Initialize Bot Profile

Source: https://bots.delta.chat/quickstart

Initializes the bot's Delta Chat profile using the CLI. This command creates the necessary configuration files and registers the bot with a specified chatmail account.

```bash
python ./echobot.py init DCACCOUNT:https://nine.testrun.org/new
```

--------------------------------

### Initialize Bot CLI

Source: https://bots.delta.chat/quickstart

Creates an instance of the BotCli class, initializing the bot with a specific name. This object is used to manage bot configuration and event handling.

```python
cli = BotCli("echobot")
```

--------------------------------

### Import Delta Chat Bot Libraries

Source: https://bots.delta.chat/quickstart

Imports necessary classes and modules from the 'deltabot-cli' and 'deltachat2' libraries. These are required for bot creation and message handling.

```python
from deltabot_cli import BotCli
from deltachat2 import MsgData, events
```

--------------------------------

### Configure Bot Status Message

Source: https://bots.delta.chat/quickstart

Sets the status or description message for the bot. This message is visible to users who interact with the bot.

```bash
python ./echobot.py config selfstatus "Hi, I am an echo-bot"
```

### Echo Message Event Handler

Source: https://bots.delta.chat/quickstart

Defines a function to handle new incoming messages. It retrieves the message text and sends it back as a reply to the same chat. This is the core logic of the echo bot.

```python
@cli.on(events.NewMessage)
def echo(bot, accid, event):
    msg = event.msg
    reply = MsgData(text=msg.text)
    bot.rpc.send_msg(accid, msg.chat_id, reply)
```

--------------------------------

### Configure Bot Display Name

Source: https://bots.delta.chat/quickstart
