Repeat with direction running through directions:
Carry out looking (This is the Direction Listing rule):
Let known-exits be {""};
Now known-exits is {};
Let unknown-exits be {""};
Now unknown-exits is {};
repeat with direction running through directions:
Let destination be the room-or-door direction from location;
If destination is a door:
Unless destination is undescribed: [This should cover the Standard Rules' implementation of hidden doors]

Let destination be the other side of destination from location;
If destination is visited or destination is known, add "[Destination] [are] [direction] (through [throughfare])" to known-exits;

Else:

else say "There are exits [unknown-exits].";

Chapter 1 - Using this Extension
Chapter - Using this Extension
The main purpose for this extensions is for testing and development work, when room connections change and updating room descriptions can be easily forgotten.
To use this framework, you need to download and install it (which you probably have if you're reading this) and include it in your story:
The main functionality will come by just importing the extension in an Inform 7 project:
*:
Include Directionality by Fictitious Frode.
After printing the room description, Inform will now print a line listing all the exits from the current location.
If the player has knowledge of the destination by visiting it, the name will also be listed.
Note that this does not check that the player knows that this exits leads to the destination.

Section 1.1 - Exploration
The main purpose for this extensions is for testing and development work, when room connections change and updating room descriptions can be easily forgotten.
For games where the player is "exploring" an area that is known to the character, it's possible to set rooms as familiar, in order to have them show up in the destination listing.
Eric Eve's Epistemology extension is used to provide this support.
Section - Known Rooms
The Library is north of the Hallway.
The Hallway is familiar.
For games where the player is "exploring" an area that is know to the character, it's possible to set rooms as known, in order to have them show up in the destination listing.
When determining wether an exit is known or unknown, it's not the exit that's being evaluated but the destination.
This has some implications for rooms that are accessible from multiple directions, and shortcuts.
Secret doors are handled according to the Standard Rules; a door that is not described is not listed.
The Library is north of the Hallway.
The Hallway is known.

Chapter - Technical Notes
2015-01-26 (Release 1)
When determining wether an exit is known or unknown, it's not the exit that's being evaluated but the destination. This has some implications for rooms that are accessible from multiple directions, and shortcuts.
Initial functionality.

Release 2 (In development)
Secret/hidden connections are not handled, but is a point for future updates.
Incorporated Eric Eve's Epistemology instead of the custom 'known/unknown' property.
Support for hidden doors, as implemented in the Standard Rules (using undescribed to imply the player is unaware they exist)
Minor documentation changes.
