reddit.wikidownloader

A Python Reddit API Wrapper (PRAW) script to download all of the accessible wiki pages of multiple Reddit subreddits.

1. Authentication credentials are not hardcoded in the script. Reddit site auth is done in a standard 'praw.ini' file. You will need to create and use this. Everything else is provided via command line parameters.
2. This will dump all accessible wiki pages into corresponding markdown language files. It will keep the heirarchy of nested document names.
3. Special files can be designated to preserve original formatting. There are (5) that are preserved by default:
   1. automoderator-schedule (yaml: automoderator schedule)
   2. config/automoderator (yaml: automoderator config)
   3. config/stylesheet (css: HTML stylesheet for the subreddit)
   4. usernotes (json: Reddit Toolbox usernotes)
   5. toolbox (json: Reddit Toolbox settings)

Common Errors

• Error: PRAW (invalid_grant error processing request)
  • This most likely means that you misentered your 2FA code. However, you should also verify your credentials in the praw.ini file.
• Error: /r/<subreddit>/wiki, (HTTP 403: Forbidden)
  • This most likely means that the subreddit's wiki is disabled. It's possible that you might be banned from that subreddit's wiki.
• Error: /r/<subreddit>/wiki, (HTTP 429: Too Many Requests)
  • This means that you exceeded the rate limit of your connection to Reddit's API. The script exits to prevent you from being banned. Try lowering the hardcoded REQUESTS_PER_MINUTE script variable, or stop using Reddit with the same account until the script is finished.
• Error: '<name>' site section does not exist in praw.ini, exiting...
  • This means that the praw.ini file is not properly set up. Look at the 'example-praw.ini' file for required fields and formatting examples.
• FileNotFoundError: [Errno 2] No such file or directory: 'wikis/<subreddit>/config/automoderator.yaml'
  • This most likely means that you are running an older version of the script that did not properly automatically create subdirectories in certain operating system environments. This has been fixed.
