Usage: pos entertainment send <plugin> [--print] [--markdown] [plugin args...]

Run an entertainment plugin, capture its output, and send it via Telegram.

Plugins are scripts that fetch a public API and print the message to stdout —
that stdout is what gets sent.

Modes:
  (default)     Send the plugin output to Telegram (silent)
  --print       Print the output locally instead of sending
  --markdown    Send with Markdown parse_mode (via pos communication telegram)

Available plugins:
$plugins

Environment:
  ENTERTAINMENT_DIR   Override the plugin directory

Config (per plugin): ~/.config/linux_post_install/entertainment.env

Examples:
  pos entertainment send weather
  pos entertainment send weather --print
  pos entertainment send joke --markdown
