HUGO Library Changes File Maintained by Julian Arnold (jools@arnod.demon.co.uk) This file details important differences between versions of the standard Hugo library by Kent Tessmann (from v2.3.0 onwards). Important differences are ones which fix bugs, add features, or otherwise affect the functioning and/or functionality of the library. Each release of the library also contains numerous small changes: altered formatting, restructured code, additional or reworded comments, and so on. These differences will not be mentioned. ________________________________________________________________________ v2.3.0, for use with HC v2.3 ________________________________________________________________________ grammar.g 14,263 10:42:40 17 Mar 1997 hugofix.g 2,432 09:53:50 27 Jan 1997 hugofix.h 5,196 10:56:18 18 Mar 1997 hugolib.h 114,408 09:47:18 20 Mar 1997 objlib.h 44,328 09:43:30 20 Mar 1997 verbstub.g 4,481 11:43:50 10 Jan 1997 verbstub.h 3,558 11:43:38 10 Jan 1997 ________________________________________________________________________ ________________________________________________________________________ v2.3.1, for use with HC v2.3 ________________________________________________________________________ grammar.g 14,263 10:00:14 26 Mar 1997 hugofix.g 2,432 10:00:32 26 Mar 1997 hugofix.h 5,200 10:00:26 26 Mar 1997 hugolib.h 115,376 12:31:22 02 Apr 1997 objlib.h 44,306 12:38:20 02 Apr 1997 verbstub.g 4,481 10:00:48 26 Mar 1997 verbstub.h 3,558 10:00:38 26 Mar 1997 ________________________________________________________________________ 1. The output of the $di (audit directions) debugging verb from hugofix.h has been tidied. 2. The HoursMinutes routine in hugolib.h can now take an optional second argument to specify military 24-hour time. For example: HoursMinutes(847) prints 2:07 p.m. HoursMinutes(847,true) prints 14:07 3. The DoGo routine in hugolib.h now ensures object does not have a door_to property, and is enterable, before passing control to the DoEnter routine. This fixes a bug to do with ENTERing or GOing to an `enterable' object with a `door_to' property-- previously this would cause a stack overflow, as DoGo and DoEnter would call each other endlessly. 4. The component class, defined in objlib.h, now inherits from the scenery class, also defined in oblib.h, and is part_of the nothing object by default (previously it did not necessariy have the part_of property). ________________________________________________________________________ v2.3.2, for use with HC v2.3 ________________________________________________________________________ grammar.g 14,309 14:38:24 16 Apr 1997 hugofix.g 2,352 12:41:00 16 Apr 1997 hugofix.h 5,486 10:23:20 21 Apr 1997 hugolib.h 119,891 11:24:12 29 Apr 1997 objlib.h 44,992 09:47:52 02 May 1997 verbstub.g 4,481 12:41:14 16 Apr 1997 verbstub.h 3,402 12:41:08 16 Apr 1997 ________________________________________________________________________ 5. A new global, `player_person', has been added to hugolib.h. This should be set to either 1, 2, or 3 (2 is the default) to reflect whether library messages (ie, those contained in routines Message in hugolib.h and OMessages in objlib.h) are to be given in the first-, second-, or third-person. For example: VALUE PERSONAL EXAMPLE PRONOUN MESSAGE --------------------------------------------------- 1 I I already have that. we We already have that. 2 you (s.) You already have that. you (pl.) You already have that. 3 he/she/it He/she/it already has that. they They already have that. Being a global the value of `player_person' can be changed during play. NOTE: Depending on the value of `player_person' the player object should either have, or not have the `plural' attribute set (ie, `player is [not] plural'): VALUE PERSONAL ATTRIBUTE PRONOUN -------------------------------------------- 1 I player is plural we player is plural 2 you (s.) player is plural you (pl.) player is plural 3 he/she/it player is not plural they player is plural NOTE: The `name' property of the player object should also reflect the value of `player_person': VALUE PERSONAL NAME PRONOUN ---------------------------------------------------------------- 1 I player.name="I" we player.name="we" 2 you (s.) player.name="you" you (pl.) player.name="you" 3 he/she/it player.name="he"/"she"/"it" (or a proper noun, ie, "Bob") they player.name="they" (or a proper noun, ie, "men of Harlech") 6. The global `nest', declared in hugolib.h, has been renamed to `list_nest', to better reflect its purpose (`list_nest' is used in various library routines which print a list). 7. The `extra_scenery' check (which checks the players input for words listed in the current location's `extra_scenery' property) in routine Parse in hugolib.h, now begins its checking at the second word of the input (ie, `word[2]'), rather than the first. This ensures that verb words are not considered during this check. 8. (See also: 2.) Routine HoursMinutes in hugolib.h previously had three bugs: a) midnight in 12-hour format was printed as "0:00 a.m."--it is now "12:00 a.m."; b) hours before noon in 24-hour format were printed as, ie, "5:00"--they are now, ie, "05:00"; c) hours before noon in 24-hour format were still suffixed with "a.m."--they no longer are. 9. (See also: 5.) Routines The and Art in hugolib.h now take optional true-or-false second arguments, which only take effect if the first argument is equal to `player' and `player_person' equals 1. In full: The(player) prints "I" The(player, true) prints "me" Art(player) prints "I" Art(player, true) prints "me" 10. (See also: 5, 9.) If the first argument is equal to `player' and `player_person' equals 1 routine IsorAre in hugolib.h prints " am" or "'m" rather than " are" or "'re". 11. (See also: 5, 9, 10.) A new routine, MatchPlural, has been added to hugolib.h, as a requirement of the new "player person" rules. MatchPlural is called with three arguments, , , and . It simply prints if is not `plural', or if is `plural'. For example: print CThe(player); MatchPlural(player, "doesn't", "don't"); \ " need to refer to that." 12. Previously rooms were not being marked as `visited'. Thus a full description was given whenever the player entered a room, regardless of `verbosity', and whether or not he had been there before. This behaviour has been fixed. 13. Routine DoEnter in hugolib.h no longer allows the entering of objects in the players inventory (response is "You can't enter that"). 14. (See also: 5, 9, 10, 11.) Routines Message in hugolib.h and OMessages in objlib.h updated to work with the new "player person" rules. 15. Object definitions for compass directions in objlib.h have been re-ordered. They are now defined, starting with north (`n_obj'), clockwise around the compass. Ie, `n_obj', `ne_obj', `e_obj', `se_obj', etc. Previously they were given in the (somewhat illogical) order `n_obj', `s_obj', `e_obj', `w_obj', `ne_obj', `se_obj', `nw_obj', `sw_obj'.
