This script fetches top n submissions per subreddit, and sends them via emails if a submission's score or number of comments exceeds a certain threshold.

1. Clone the repository

2. Go to Reddit and create a developper application for script use.

3. Create a praw.ini file in the repository folder following the doc

4. Run reddit_bot.py with your config options, like below

   $ python3 reddit_bot.py --reddit_config bot1 --subreddits machinelearning datascience python --from_address [email protected] --from_address_pass password --to_address [email protected] [email protected]
   

   Command line arguments

   optional arguments:
   -h, --help            show this help message and exit
   --reddit_config CONFIG
                           specify config section for Reddit config file, e.g. praw.ini
   --subreddits [STRING [STRING ...]]
                           A list of subreddits
   --limit INT           maximum num of posts per subreddit
   --score INT           minimun score on a particular submission
   --num_comments INT    minimun num of comments on a particular submission
   --from_address EMAIL  email addr from which to send contents
   --from_address_pass EMAIL_PASS
                           password for email addr from which to send contents
   --to_address [EMAIL [EMAIL ...]]
                           email addr to which to send contents
   

5. Additionally, you can create a run.sh script based off the code in step 4, and setup a cron job for automation tasks. For example, to run it daily at 4 p.m., we can put this in our crontab file:

   0 16 * * * cd /home/jameswong/projects/redditbot/ && /bin/bash run.sh
