GifvBot is a Reddit bot that automatically posts the .gifv link in response to submissions containing a link to animated images/videos on imgur. It is currently active and running under the username u/gifv-bot.

For general information not related to the code see the FAQ.

Since this is a C# console application, you'll need a current version of Visual Studio.

1. Create a Reddit account.
2. Authorize the account so it can access the Reddit OAuth API. You'll need to create a Reddit application and then perform the authorization flow manually. Make sure to use duration=permanent so you can get a refresh token. See Reddit's documentation for detailed instructions.
3. Set up environment variables.
   • GIFVBOT_REDDIT_USERNAME: the username of the Reddit account
   • GIFVBOT_REDDIT_CLIENT_ID: the ID of the Reddit application
   • GIFVBOT_REDDIT_SECRET: the secret of the Reddit application
   • GIFVBOT_REDDIT_REFRESH_TOKEN: the refresh token you acquired after performing the authorization flow with duration=permanent
4. Start the application. It will keep running on its own.

Note: By default, comment posting is disabled to prevent duplicate comments since there is already an instance of this bot running. To enable comment posting regardless, set the GIFVBOT_IS_COMMENTING_ENABLED environment variable to true (you probably shouldn't do this!).
