< p class = "commentary" > The semantics of rulebooks grew from their original mid-00s design of being
simple action-focused sets of game rules (for interactive fiction) to a point
in 2009 where they could essentially perform anything which a function in a
functional programming language such as Haskell could do. Their original
game-based purpose nevertheless still shows through in places, as with the
quaint idea of having enumerated ways in which they finish (see < a href = "2-fao.html#SP2" class = "internal" > outcomes< / a > ).

referred to in Inform 7 source text. In fact two alternative forms of this noun
are also created, which are both synonyms for it. Thus if a "coordination"
rulebook is created, it can be referred to as any of "coordination", "coordination rules"

< p class = "commentary firstcommentary" > < a id = "SP11" class = "paragraph-anchor" > < / a > < b > § 11. Attaching and detaching rules. < / b > The following routine contains a bit of a surprise: that the act of
placing a BR within a given rulebook can change it, by altering the way
it acts on its applicability test. This is a device needed to manage
the parallel rulebooks for action processing for the main player character
and for third parties. Though the code below does not make this apparent,
the changes propagate down through the BR to the phrase structure itself.
This is necessary because they manifest themselves in the compiled code
of the phrase, but it is also unfortunate, because it is possible that
the same phrase is used by more than one BR. If it should happen that
BRs are created to place the same phrase into two different rulebooks,
therefore, and which have different actor-testing settings, the outcome
would be confusing. (As unlikely as this seems, it did once happen to a
user in beta-testing.)

< p class = "commentary" > the following grammar peels away the easier-to-read indications at the

"printing", it wouldn't match here, because "printing the name" is longer.

of a scene rather than just a scene's name. In effect, the stem here consists
of the two outer words and is discontiguous.

from the compiler, or from one of the kits, or both. The list below looks long,
but actually most of these are special only in that they are shown in their

other rulebooks.
