Some things you may now know that you might not have known before:


  • PennMUSH distinguishes player connections (descriptors) from player objects in the database.
  • PennMUSH has two parsers: expression and command. The command parser calls the expression parser when evaluating commands and arguments, but the expression parser does not call the command parser.
  • Functions and commands are not interchangeable
  • Square brackets tell the expression parser to parse their contents with mandatory function checking, and are only necessary when the expression parser wouldn't check for functions on its own anyway.
  • PennMUSH has four queues that are merged into a single ordered list of commands to be run
  • $commands cant get their unsubstituted arguments in %0-%9. If they need raw arguments, they must parse them out of %c.
