Notify-Email

Notifyemail is a package that sends notifications via email when your code finishes running on a remote server. With the assistance of Notifyemail, you can receive the running results of your program at the first time, even if your server is within a Local-Area-Network (LAN). It also works well with other environments like Google Colab and notifies you of the results when program finished.

Hope it can do some help for your project :)

Requirements

You need a public email.

About how to setup a public email:

• smtp_usage.md
• smtp_usage_chinese.md

How to install

Use pip to install our module:

pip install notifyemail

How to use

First, import notifyemail module.

import notifyemail as notify

Add the following line at the start of your program:

notify.setup(mail_host='smtp.163.com', 
             mail_user='xxxxxx@163.com', 
             mail_pass='xxxxxx',
             log_root_path='log', 
             mail_list=['xxxxxxx@xxx.com'])

This line will start a background task that keeps monitoring your program running status and server status. Upon your program ends or encounters a failure, the background process will try to send you an email with program outputs and other essential information.

After the above setting, all your terminal outputs like print or error information will be logged. You may also use the following two methods to add more text or files into the email.

# You may use notify.add_text() to add words into the body of the email.
notify.add_text('This is the first line goes into the mail text.')
notify.add_text('This is the second line goes into the mail text.')

# You may use notify.add_file() to add a folder into your email.
# The folder will be compressed and attached to the email after your program ends.
A_file_path = './examples'
notify.add_file(A_file_path)

Example

An example is shown here:

# 1. Import the package.
import notifyemail as notify

# 2. Please reset Notify frontend before running any task, otherwise 
# some output may not be logged.
notify.setup(mail_host='smtp.163.com', 
             mail_user='xxxxxx@163.com', 
             mail_pass='xxxxxx',
             log_root_path='notify_log', 
             mail_list=['xxxxxx@xxx.com'])

# 3. System output will be logged and you may check in your email.
print('Hello world!')
import time
for i in range(5):
    print(f'{i}: Your program is running...')
    time.sleep(1)

# 4. You can use notify.add_text() to add words in the body of the email.
notify.add_text('This is the first line goes into the mail text.')
notify.add_text('This is the second line goes into the mail text.')

# 5. You can use notify.add_file() to add a folder into your email.
# The folder will be compressed and attached to the email after your program ends.
a_file_path = './result_folder'
notify.add_file(a_file_path)

# 6. After meeting an error or for any reason, the program died, notifyemail will try to 
# send the program output to the listed mailboxes. This can help you diagnosis 
# the program issues.
print('Here comes an error!')
something_went_wrong_here

After running the above example, you may receive an email as shown below:

The attachment file contains the system output:

*****************LOG_Cache_2023_08_04_14_21*****************

Change log

2023-08-04:

• Integrate notify.Reboost and notify.send_log into notify.setup function. You can call notify.setup at the beginning of your program instead of calling notify.Reboost and notify.send_log separately. The previous method is still supported.
• Add examples under ./examples.
• Re-arranged the notifyemail project structure.
• Translate all comments into English.
