• inspired by esmBot
• uses discord.py (python discord lib)
• uses FFmpeg for most media functions
• uses selenium and ChromeDriver to render captions in html with Chrome
  • although not the fastest approach, it is very readable, flexible, and easy to work with/expand.

verified working on windows 10/11 and ubuntu 18/20. will probably work on macos and other linux distros if the below libraries are available but theyre untested and unsupported.

the bot uses many CLI programs for media processing.

• FFmpeg - not included but easily installable on windows and linux
  • If installing on ubuntu, ensure that ffmpeg version >= 4
• gifski - windows executable is included. linux version downloadable from the website
• pngquant - windows executable is included. installable on linux with sudo apt-get install pngquant
• ChromeDriver - ChromeDriver 91 for both windows and linux are included. They have functioned as intended in my testing, but here's the website anyways.
  • ChromeDriver requires there to be an installation of chrome on your system accessible via path or similair. Your chrome version doesn't have to be the exact same as your chromedriver version, but it should be similar
  • you may need to run sudo chmod +x ./chromedriver87 on linux to make it a working executable.
• ImageMagick - not included but downloadable here
• ExifTool - windows executable is included. installable on linux with sudo apt-get install exiftool https://exiftool.org/
• apngasm - windows executable is included. installable on linux with sudo apt-get install apngasm
• glaxnimate - downloadable on its website
  • this library is not yet used. it is needed to render lottie stickers, but I am currently having issues installing the python bindings on windows.

• This project uses pipenv, run pipenv install to install the required dependencies.
  • check pipenv's repo for more info on pipenv usage.
  • aubio and PyAutoTune are built from source on installation.
    • on Windows this will require the MSVC compiler
    • on Linux this will require gcc

• create a copy of config.example.py and name it config.py.
• insert/change the appropriate config settings such as your discord api token. be sure not to add or remove quotes.
• the 2 required config settings to change for proper functionality are the discord and tenor tokens.

• developed and tested on python 3.8. use that or a later compatible version

• once you've set up all of the libraries, just run the program with python main.py (or python3.8 main.py or whatever your python is named). make sure it can read and write to the directory it lives in and also access/execute all the aforementioned libraries
  • if using pipenv, run pipenv run python main.py or open the venv shell with pipenv shell and then run python main.py
• terminate the bot by running the shutdown command, this will probably close better than a termination

1. install heroku cli and log in
2. run heroku create in the mediaforge directory to create a heroku app
3. add buildpacks

   heroku buildpacks:add https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git
   heroku buildpacks:add https://github.com/heroku/heroku-buildpack-google-chrome.git
   heroku buildpacks:add https://github.com/heroku/heroku-buildpack-chromedriver.git
   heroku buildpacks:add heroku-community/apt
   heroku buildpacks:add heroku/python

4. add Heroku Postgres addon
5. set up bot config
   • create a local config file
     • don't worry about chrome_driver_linux, this option is ignored in heroku production.
   • encode the file as base64
     • on linux:
       • base64 config.py prints the output to terminal
       • base64 config.py > config.txt writes the output to config.txt
     • with python:

       import base64
       with open("config.py", "rb") as f:
           out = base64.b64encode(f.read())
       print(out)  # write to terminal
       # write to file
       with open("config.txt", "wb+") as f:
           f.write(out)

   • save file as config option (replace <BASE64OUTPUT> with the output from earlier.)

     heroku config:set PRIVATEFILE_config.py=<BASE64OUTPUT>

     • note: if you want other private files deployed to heroku, do the same steps but replace config.py in PRIVATEFILE_config.py with the filename.
6. start app

   heroku ps:scale worker=1

NOTE: currently, guild-specific prefixes wont persist after a re-deployment. heroku files are temporary and i haven't YET written the code to interface with their databases.
