Sharing presentations

• send file
  • user can start presentation with present -f present.tar.gz
  • user can unpack file, enter folder and execute present

Customizations & security

• present will watch for three files:
  • present.env in active directory (this will not override already existing ENV values)
  • .env in active directory (this will override already existing ENV values)
  • present.env in user HOME directory (this will override already existing ENV values)
• .env file or corresponding variables can be used to customize behavior

  ADMIN_PWD=AdminPassword123
  USER_PWD=user
  ASK_USERNAME=false
  PORT=8080
  NEXT_PAGE=ArrowRight,ArrowDown,PageDown,Space,e
  PREVIOUS_PAGE=ArrowLeft,ArrowUp,PageUp
  TERMINAL_CAST=r,b
  TERMINAL_CLOSE=c
  MENU=m

• if ADMIN_PWD is set, only users authorized with that password can execute the code
  • if ADMIN_PWD is not provided, it will be generated and written on console
    • with ADMIN_PWD_DISABLE=true you can remove need for admin password
  • admin password can be entered on /login url (for example http://localhost:8080/login)
• if USER_PWD is set, all 'users' will need to enter password to see the presentation
• rest are pretty self explanatory (also in examples are defaults for all options)
