 Ordinary Room Description  v 4.0.220524    An extension to go with Room Description Control, which emulates as closely as possible the behavior of Inform defaults, but allows the intervention of Room Description Control.
 Mood Variations  v 3.1    Allows the author to define a mood value for characters and then use text substitutions such as '[when bored]The king fidgets on his throne[or sleepy]The king snores[at other times]The king grins[end when].' Moods will be interpreted in 'writing a paragraph' and similar contexts as the mood of the person described in the paragraph, but at other times according to the mood of the person to whom the player is currently speaking.
 Modified Exit  v 6    Changes the handling of the EXIT action, allowing commands such as EXIT PLATFORM and GET OUT OF CHAIR, making characters leave enterable objects before traveling, and altering the default interpretation of >OUT when the player is neither inside an object nor in a room with an outside exit. Updated for adaptive text.
 Modern Conveniences  v 5    Modern Conveniences creates kitchen and bathroom kinds of room, which will automatically be furnished with a set of plausible appliances. (This was originally an example in the manual of how to create extensions, and an annotated version may still be found there.) Version 3 adds compatibility with Measured Liquid, modeling flowing water from taps.
 Menus  v 3    A table-based way to display full-screen menus to the player.
 Measured Liquid  v 6.3    Measured Liquid provides a concept of volume, together with the ability to fill containers, pour measured amounts of liquid, and drink from containers. It handles mixtures as well, if desired. It is compatible with, but does not require, the Metric Units extension by Graham Nelson.
 Locksmith  v 13    Implicit handling of doors and containers so that lock manipulation is automatic if the player has the necessary keys.
 Introductions  v 2    Introductions provides an introductory paragraph about objects in a room description the first time the player looks in that location. It also allows the author to add segue text that will appear between one description and the next.

 Glulx Text Effects (For Glulx Only)    v 6    Gives control over text formatting in Glulx.

 Dishes  v 2    Dishes is a convenience extension for use with Measured Liquid. It provides some standard-sized cups, glasses, graduated measuring cups, jugs, bottles, etc., as well as a corked bottle kind that opens with the use of a secondary cork object.
 Deluxe Doors  v 4    Allows for doors that are implemented as having independent 'faces' -- to put a knocker on that can only be seen from on side, for instance, or to allow the player to lock one side with a key but the other with a latch. Also introduces a 'latched door' kind.
 Computers  v 8.2    Computer hardware and software, including search engines and email programs. Version 3 adds handling for batteries and cords, if we include Power Sources by Emily Short (which itself depends on Plugs and Sockets by Sean Turner).

 Basic Screen Effects  v 8    Waiting for a keypress; clearing the screen. Also provides facilities for changing the foreground and background colors of text, when using the z-machine. These abilities will not function under Glulx.
 Basic Help Menu  v 1    Provides a HELP command which brings up a menu giving standard instructions about IF.
 Automated Drawers  v 6    Creates a drawer kind of container, which is designed to be part of an item of furniture. Automatically parses names such as 'top drawer' or 'fourth drawer' or 'left drawer'; adds some features for describing furniture with drawers.
 Assorted Text Generation  v 5    --
 Approaches  v 8    Approaches provides a GO TO place action which allows the player to move through visited rooms to a new location. It also allows other characters to traverse the map to named locations. It is designed to work with Locksmith by Emily Short, but as of Version 8, that is an optional inclusion.
 Eric Eve  (19 extensions)
 Variable Time Control  v 4    Allows individual actions to take a different number of seconds, or no time at all. Also allows the standard time taken per turn to be defined as so many seconds, which can be varied during the course of play
 Underside  v 6.1    Allows objects to be put under other objects. An underside usually starts out closed so that its contents are hidden from view. Requires Version 7 (or later) of Bulk Limiter; the space under objects is limited by bulk. Underside is compatible with Version 10 or later of Implicit Actions, but does not require it. Version 5 of Underside avoids features deprecated in Version 6E59 of Inform.
 Text Capture  v 8.1    Allows the capture of text that would otherwise be sent to the screen, so that the text can be further manipulated, displayed at some other point, or simply discarded. Version 6/120511 allows the use of unicode in Glulx.
 List Controller  v 4    Provides a means of using tables as shuffled, cyclic or stoping lists. This is an alternative to List Control that uses list controller objects instead of a Table of Table Types.
 List Control  v 4    Provides a means of using tables as shuffled, cyclic or stop lists.
 Limited Implicit Actions  v 3.0.1    A cut-down version of Implicit Actions for use where code size may be restricted and the full functionality of Implicit Actions is not needed. Compatible with Locksmith by Emily Short.
 Implicit Actions  v 13.1    Provides implicit taking, opening, closing, locking and unlocking actions for a variety of cases where this makes for smoother game play. The extension also defines phrases which make it easy to define additional implicit actions if desired. Version 11 can be used with Locksmith by Emily Short (although Implicit Actions covers most of what Locksmith does, and in most cases it will be better to use Implicit Actions without Locksmith). Requires Version 8.1 (or above) of Text Capture by Eric Eve.
 Hiding Under  v 4    Allows things to be hidden under other things, using a many-to-one underconcealment relation. Can be used either standalone (with basic functionality) or in conjunction with Underside (to add fuller functionality to both extensions). Version 3 of Hiding Under avoids using phrases deprecated in Version 6E59 of Inform.
 Exit Lister  v 11    A status line exit-lister and an EXITS command, with optional colouring of unvisited exits. Selected rooms and doors can be optionally be excluded from the list of exits.
 Epistemology  v 9    Keeping track of what the player character knows and sees.
 Conversational Defaults  v 3    Provides a set of rules to facilitate defining default conversational responses for different conversational commands targeted at various NPCs. This extension requires Conversation Framework.
 Conversation Suggestions  v 6.2    Provides a means of suggesting topics of conversation to the player, either in response to a TOPICS command or when NPCs are greeted. This extension requires Conversation Framework. Version 3 makes use of Complex Listing by Emily Short if it's included in the same game rather than indexed text to generate a list of suggestions.
 Conversation Responses  v 7    Provides a meaning for defining responses to conversational commands (such as ASK FRED ABOUT GARDEN) as a series of rules.
 Conversation Package  v 3    This extension includes both Conversation Nodes and Conversation Suggestions, and makes the suggestions aware of conversation nodes. It therefore includes the complete conversational system in one package. It also requires Conversation Responses, Conversational Defaults, Conversation Framework and Epistemology. The documentation for this extension give some guidance on how these other extensions can be mixed and matched.
 Conversation Nodes  v 7    Builds on Conversational Defaults and adds the ability to define particular points in a conversational thread (nodes) at which particular conversational options become available.
 Conversation Framework  v 12    A framework for conversations that allows saying hello and goodbye, abbreviated forms of ask and tell commands for conversing with the current interlocutor, and asking and telling about things as well as topics.
 Bulk Limiter  v 9    Containers and actors that limit their contents by bulk
 Alternatives  v 3    Allows checking the presence of an object or value in a set of objects or values with new either/or and neither/nor phrases. e.g., 'If the noun is either the carrot or the potato:', or 'Instead of eating something when the noun is neither the cake nor the pudding:'

 Verb Stripping  v 2.0.220521    Removes a number of verbs from the standard rules; verbs which might cause confusion in a game whose theme is not adventure.
 Undo Output Control  v 6.0.220529    Provides hooks into UNDO processing, including multiple ways to suspend UNDO temporarily, to place limitations on UNDO (such as allowing only one UNDO in a row), to undo the current turn from code, and to control when the game state is saved. Using the latter, we can effectively control which turn UNDO returns us to. Also allows the story to edit a blank command before analyzing it. Updated to Inform 10.1.

 Neutral Standard Responses  v 5.0.220521    Replaces misleading, vague, and narratively-voiced parser messages with instructive, clarifying, and neutral versions, respectively. For Inform 10.1.0.
 Nathanael's Debug Tools  v 3.0.220522    Miscellaneous stuff I like to have built in when debugging and programming, but would never want to relase.
 Nathanael's Cookbook  v 6.0.220604    This is just a collection of documentation and worked examples illustrating various features of Inform. There isn't much in the extension per se, but the examples in the documentation can be click-pasted in the Inform IDE for convenience.
 Large Game Speedup  v 6.0.220524    Performance improvements for games with many objects, or with nested loops over objects, by avoiding looping over all objects.
 Initial Cursor At Top Or Bottom  v 2.0.220604    This small extension eliminates the three newlines printed before the banner. It also provides a tool to attempt to place the cursor at the bottom of the screen, like old Infocom games. Due to wild variance between interpreters, it is not reliable.
 Gender Speedup  v 3.0.220524    When using Gender Options, clean up some I6 internals with functions related to gender which are irrelevant to English or rendered obsolete with Gender Options. Since these are called in the depths of ListWriter this should slightly improve speed. Not included in Gender Options due to likely interference with other extensions. Requires Gender Options. Will not work with languages with gendered plurals. Tested with Inform 10.1.
 Gender Options  v 4.0.220604    More broad-minded English language gender/number model where male, female, and neuter are three separate true-false properties. Allows for objects to respond to any specified combination of HE, SHE, IT, and THEY. As fast as the Standard Rules. Tested with Inform v10.1.0.
 Extended Banner  v 6.0.220604    More control over what is printed in a banner, including an easily-included copyright line.
 Compliant Characters  v 5.0.220524    Report parsing errors to the player when ordering other characters to do things. Inform 7 normally redirects these errors to 'answer ' so that the character can respond to arbitrary statements. But in an story with compliant characters who the player orders around routinely, that is frustrating to a player who has made a typo; this helps out the player. Requires version 5 of Neutral Standard Responses. Tested with Inform 10.1.0.
 Character Portraits  v 1.0.220523    Provides a complex system for customzing the printed descriptions of characters wearing or carrying lots of stuff, similar to the room description system in Standard Rules. Requires Large Game Speedup by Nathanael Nerode.

 Unsuccessful PC Attempt  v 2    Will run the Unsuccessful Attempt By rules for all characters, including the player. Also silences the library messages printed by the built-in Check rules.
 Scope Control  v 2    Allows us to ask why the Deciding the Scope For Something activity is running, so we can modify the scope only when we absolutely need to. Highly useful for giving NPCs commands over telephones or while in darkness, creating 'can hear' relations, or modifying how Inform parses the command line.
 Phrases For Tables With Topics  v 3    This grants five new phrases regarding the player's command, the matched text, and the topic understood: if one is a topic listed in a table, if one includes or matches a topic listed in a table, what corresponds to one within a table, and the last phrase corrects a bug so the topic understood may be used within an understand-as-mistake line.
 Permission To Visit  v 7    In lieu of compass directions, we may VISIT, ATTEND, GO TO, and FIND various people, events, places, and things. Characters may INVITE, PERMIT, and FORBID each other to or from their respective domains.
 Editable Stored Actions  v 10    This extension extends section 12.20 of Writing With Inform. The individual parts of a stored action -- actor, noun, second noun, action name -- can be changed directly. Also exposes new parts: request, text, participle, preposition, number, and each kind of value.
 After Not Doing Something  v 2.1    Allows us to write rules that happen after an action fails, such as 'After not examining or searching something'. 'After Not Doing Something' is short for 'After Failing To Do Something'
