Chapter 6 - The Turntable
[The turntable is a supporter. It is scenery. The carrying capacity is 1. The description is "A swiftly rotating platform able to go clockwise or anticlockwise. It is currently set to [rotation-direction]." Understand "table" or "turn table" as the turntable.
Rotation-direction is a kind of value. The rotation-directions are clockwise and anticlockwise. Understand "counterclockwise" and "widdershins" as anticlockwise. The turntable has a rotation-direction.
Understand "set [turntable] to [rotation-direction]" as setting it to the direction. Setting it to the direction is an action applying to one thing and one rotation-direction.
Instead of vaguely setting the turntable:
if the turntable is clockwise, try setting turntable to the direction anticlockwise; otherwise try setting the turntable to the direction clockwise.
Carry out setting it to the direction:
now the rotation-direction of the turntable is the rotation-direction understood.
Report setting it to the direction:
say "[The turntable] now goes [the rotation-direction of the turntable]."
Every turn when the turntable is visible and something is on the turntable:
if not looking:
follow the turntable-turning rule;
say paragraph break.
This is the turntable-turning rule:
let the chosen article be a random thing on the turntable;
let X be the chosen article;
let the goal text be indexed text;
let goal text be "[printed name of the X]";
if the turntable is clockwise
begin; [put first letter at the end, as in ape --> pea]
if the goal text matches the regular expression "(.)(.*)", replace the regular expression "(.)(.*)" in goal text with "\2\1";
otherwise; [put last letter at the front, as in arc --> car]
if the goal text matches the regular expression "(.*)(.)", replace the regular expression "(.*)(.)" in goal text with "\2\1";
repeat with item running through things in the repository
if the goal text exactly matches the regular expression "[item]", now the chosen article is the item;
if the chosen article is not X
now the chosen article is not proffered by anything;
now everything which proffers X proffers the chosen article;
now everything which is on the turntable is in the repository;
move the chosen article to the turntable;
say "[if looking]After the turntable does its work,[otherwise]The turntable whirls faster than we can follow, and when it is done[end if] there [is-are a list of things on the turntable]. ";
if exactly one thing is on the turntable, say "It does";
otherwise say "[The list of things on the turntable] do[es]";
say " not change, however. ";
say "The turntable spins for a moment, [one of]then dies down again[or]without effect[or]without changing [the list of things on the turntable][at random]. ";
Rule for disclosing exterior of something (called special-target) which is on the turntable:
say "[The special-target] [is-are] spinning rapidly [rotation-direction of the turntable] on [a turntable][if a thing is on the turntable], together with [a list of mentionable things which are on the turntable][end if]. [run paragraph on]";
follow the turntable-turning rule.
Rule for disclosing contents of the turntable (this is the turntable-content rule):
say "On [the turntable], [a list of things on the turntable] spin[s] [rotation-direction of the turntable]. [run paragraph on]";
follow the turntable-turning rule. ]
