This project is meant to become a tool that can be used both to play a clone of the classic interactive fiction (IF) game, Adventure, AKA ADVENT, as well as an abstractable (eventual second project) IF game engine.

• A loop that prints a prompt, reads a text command, parses it, and attempts to execute an interpreted command.
• Classes representing verb-actions, world-objects to be acted on, and commands.
• World-object subclasses representing the player, rooms, and specific types of objects.
• Modules providing behavior for common object traits, such as being a container, movability, breakability.
• Common actions such as look, take, move between rooms, inventory, special exit command which exits the game.
• A lexicon is a collection of understood terms, which can mostly represent command verbs, but can also be other parts of speech, such as implicit nouns that are not defined as world-objects.
• A game is a class representing the current game-state in terms of the existing objects and the container-contents graph.
• Rooms with descriptions, exits and objects pulled from Z-Code rewrite of Advent.
• Compass-directions and exits with capability for obstructions.

ruby advent.rb

• Try typing common one or two word commands such as look, look object, take object
• And try directions: north, south, east, west, up, down.

• Subclass Game.
• Create room objects and link them with the exit function.
• Create objects and place them into rooms.

• Continue fleshing out the Advent game world and then, as necessary...
• Create a lot more built-in objects, maybe as modules that other objects can include.
• Create a lot more built-in verbs in the lexicon and create sensible default actions for verbs and objects.
• More tests, including some transcripts of commands and expected output, making use of parameterized $stdin and $stdout.
• More robust object interaction, including lamp-light, keys and locks, etc.
• PARSER: better semantic net parsing to accept helper words (look at obj instead of look obj, e.g.)
• Allow multiple synonyms for objects and multi-word noun names.
• Prompt for incomplete command info ("with what?")
