### Install required Python packages

Source: https://github.com/bertigert/temp-mails/blob/master/README.md

Installs the necessary Python packages for the temp-mails library, including requests, beautifulsoup4, lxml, and a specific version of websocket-client. Users might need to uninstall existing websocket packages.

```bash
pip install requests beautifulsoup4 lxml websocket-client==1.7.0
```

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

### Install temp-mails package

Source: https://github.com/bertigert/temp-mails/blob/master/README.md

Installs the temp-mails Python package using pip. It is recommended to use Python 3.12 for best compatibility.

```bash
pip install temp-mails
```

### Basic Usage with Tenminemail.com

Source: https://github.com/bertigert/temp-mails/blob/master/README.md

Demonstrates basic usage of the temp-mails library with the Tenminemail.com provider. It shows how to create an email, retrieve inbox contents, send an email, and wait for a new email.

```python
from temp_mails import Tenminemail_com
from send_email import send_email_sync

# Generate a random email address
# It is generally recommended to let the site determine a random email address, as custom ones often require additional requests.
mail = Tenminemail_com()
# Get the email (e.g. example, examplehost, example@examplehost.com)
print(mail.name, mail.domain, mail.email)

# Get all emails in the inbox
print(mail.get_inbox())

# Send the email (by signing up or similar)
send_email_sync(mail.email)

# Wait for a new email for 120 seconds and get the email data. 
data = mail.wait_for_new_email(delay=1.0, timeout=120) 
print(data)

# Get the content of the email, some tempmail services don't need this step
if data: # It returns None if something unexpected happens
    print(mail.get_mail_content(message_id=data["id"]))

```

### Using start_length for Email Waiting

Source: https://github.com/bertigert/temp-mails/blob/master/README.md

Demonstrates how to use the `start_length` argument in `wait_for_new_email` to specify the initial inbox length, useful when an email might be received before the waiting function is called.

```python
from temp_mails import Tempmail_id
from send_email import send_email_sync

mail = Tempmail_id()

# Get the old length of the inbox. If you are certain that this email is new, you can assume it's 0 and skip this step.
old_length = len(mail.get_inbox())

# Send the email
r = send_email_sync(mail.email)

# Wait for the mail using the old_length. Normally the old_length would be defined in this function call, after the email has been sent.
data = mail.wait_for_new_email(start_length=old_length)

print(data)

```

### Asynchronous Email Waiting with Threading

Source: https://github.com/bertigert/temp-mails/blob/master/README.md

Shows how to use threading with the temp-mails library for asynchronous email waiting, preventing the main program from blocking. It utilizes an Event object to signal readiness.

```python
from time import sleep
from threading import Event
from concurrent.futures import ThreadPoolExecutor

from temp_mails import Byom_de
from send_email import send_email_sync

mail = Byom_de()
print(mail.email)
  
# Set up the event which can be used by the wait_for_new_email function to signal that it's ready
is_ready_event = Event()
# Start the wait function inside of a thread
t = ThreadPoolExecutor().submit(mail.wait_for_new_email, is_ready_event=is_ready_event)

# Wait for the wait function to be ready
is_ready_event.wait()

# Send the email (by signing up or similar)
send_email_sync(mail.email)

# Get the result from the wait function
result = t.result()

print(result)

```
