This is fairly simple script which attempts to automatically add an emoji to a message on Discord. Which user's message gets which emoji on which server is determined by the "user_list.txt". User and emoji ID are required for this to work.

Getting user/server ID https://support.discordapp.com/hc/en-us/articles/206346498-Where-can-I-find-my-User-Server-Message-ID-

Emojis can be stored within the user_list.txt file in the following format: USERID SERVERID emoji_name:111222333444555666

...or as a dictionary directly in the file

A prompt for capturing user credentials would likely make this more secure. Alternatively, import them as an environment variable (not sure how secure this is), or store them in a separate file as a class, as demonstrated here (not very secure)

from terminal:

crontab -e

press 'i' for insert mode, and enter the following

* * * * * /usr/local/bin/python3.6 /Users/user/Documents/auto_emoji.py >> ~/cron.log 2>&1

* * * * * represents the cron schedule: minutes hours day(of the month) months day(of the week) -- see crontab.guru for crontab tips/examples

the next piece /usr/local/bin/python3.6 represents the Python3.6 'executable' path, and /Users/user/Documents/auto_emoji.py is where ever the Python script is saved

>> ~/cron.log 2>&1 specifies to send all output (STDERR and STDOUT) to cron.log, instead of an email (recommend)

Once done editing, press esc then :wq to write(save) and quit

Finally, make sure to give the python file itself executable permissions:

chmod +x <python file>
