Slack webm sentinel

Slack doesn't have an inline player for .webm links.

This bot fixes the problem: it tracks .webm links in messages, downloads them, converts into .mp4 and posts them back into the channel.

Configuration

Done via env variables:

Name	Required?	Description
SLACK_API_TOKEN	Yes	Bot access token (starts with xoxb-...)
NOTIFY_MODE	No	How to let users know about bot activity. Can be one of: reaction - default, will add emoji to a message with link) message - will post a message when it finds URL none - do not notify
DEBUG	No	Will set logging level to debug
TEMP_DIR	No	Will be used for downloads and video converting. Bot removes them after link is handled. Default is /tmp

Run in Docker

docker run \
  --mount type=volume,target=/tmp \
  -e SLACK_API_TOKEN=xoxb-... \
