<p class="purpose">An action pattern is a description which may match many actions or none. The text "doing something" matches every action, while "throwing something at a door in a dark room" is seldom matched. Here we parse such text into a data structure called an |action_pattern|.</p>

<p class="commentary firstcommentary"><a id="SP1"></a><b>§1. </b>Action patterns are essentially a conjunction of specifications — the
|
|
action must be this, and the noun must be that, and... While
|
|
they allow disjunction in the choice of action, all of that code is a
|
|
matter for the action name list to handle. The AP structure is a list
|
|
of conditions all of which must apply at once.
|
|
</p>
|
|
|
|
<p class="commentary">One surprising point is that the AP is used not only for action
|
|
patterns, but also in a slightly generalised role, as the condition
|
|
for a rule to be applied. Most rules are indeed predicated on actions
|
|
— "instead of eating the cake" — but some are instead in
|
|
"parametrised" rulebooks, which means they apply to a parameter
|
|
object instead of an action — "reaching inside the cabinet". These
|
|
not-really-action APs are used in no other context, and employ the
|
|
<span class="extract"><span class="extract-syntax">parameter_spec</span></span> field below, ignoring the rest.

it easier to produce helpful error messages. (We can't simply fire off

errors at the time they occur, because text is often parsed in several

contexts at once, so just because it fails this one does not mean it is

wrong.) PAPF stands for "parse action pattern failure".

<p class="commentary firstcommentary"><a id="SP10"></a><b>§10. </b>Action patterns are textual descriptions which act as predicates on actions,
|
|
that is, they are descriptions which are true of some actions and false of
|
|
others. For example,
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>taking something in a dark room</p>
|
|
</blockquote>
|
|
|

<p class="commentary">won't be true of taking the ball in the Beach, or of dropping the torch in the

Cellars. Although precisely described actions are valid as APs:

|
|
|
|
<blockquote>
|
|
<p>taking the beach ball</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">(which is true for this one action and false for all others), APs can be both

more general — as above — and even more specific:

|
<blockquote>
|
|
<p>taking the beach ball in the presence of a lifeguard</p>
|
|
</blockquote>
|

<p class="commentary">...which might not be true even if the current action is "taking the beach

|
ball".
|
|
</p>
|
|
|
|
<p class="commentary">APs can be very flexible and have the most complicated syntax in Inform. It's
|
|
not practical to make the Preform grammar as explicit as one might like, but
|
|
we'll do our best. The top level establishes who the actor will be, and whether
|
|
it is an actual action or merely a request to perform the action. There are
|
|
two versions of this: the first is for contexts where the AP might occur as
|
|
a noun (e.g., in a sentence like "Taking a jewel is felonious behaviour.").
|
|
These are always present tense, and can't be negated.

we can do is search out possibilities. If it's possible to match the action

actorless possibility can always be written.

if the resulting name matches <action-parameter> as a constant,

<p class="commentary firstcommentary"><a id="SP16"></a><b>§16. </b>"Doing it" is not the happiest of syntaxes. The idea is for this to be
|
|
a sort of pronoun for actions, allowing for anaphora, but to parse such things
|
|
naturally in all cases is wishful thinking. It enables us to write, e.g.:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>Instead of Peter taking the box for the second time, try Jane doing it.</p>
|
|
</blockquote>

possibility for confusion is too great; perhaps we should just cut this idea.

example, in "Kevin taking or dropping something", the operand is "something".

We treat words like "something" specially to avoid them being read as

"some thing" and thus forcing the kind of the operand to be "thing".

<p class="commentary firstcommentary"><a id="SP25_5"></a><b>§25.5. </b>Now to fill in the gaps. At this point we have the action name
|
|
list as a linked list of all possible lexical matches, but want to
|
|
whittle it down to remove those which do not semantically make
|
|
sense. For instance, "taking inventory" has two possible lexical
|
|
matches: "taking inventory" with 0 parameters, or "taking" with
|
|
1 parameter "inventory", and we cannot judge without parsing
|
|
the expression "inventory". The list passes muster if at least
|
|
one match succeeds at the first word position represented in the
|
|
list, which is to say the last one lexically, since the list is
|
|
reverse-ordered. (This is so that "taking or dropping something"
|
|
requires only "dropping" to have its objects specified; "taking",
|
|
of course, does not.) We delete all entries in the list at this
|
|
crucial word position except for the one matched.

<p class="commentary firstcommentary"><a id="SP31"></a><b>§31. </b>The more complex clauses mostly act on a single I6 global variable.
|
|
In almost all cases, this falls through to the standard method for
|
|
testing a condition: we force it to propositional form, substituting the
|
|
global in for the value of free variable 0. However, rule clauses are
|
|
allowed a few syntaxes not permitted to ordinary conditions, and these
|
|
are handled as exceptional cases first:
|
|
</p>
|
|
|
|
<ul class="items"><li>(a) A table reference such as "a Queen listed in the Table of Monarchs"
|
|
expands.
|
|
</li><li>(b) Writing "from R", where R is a region, tests if the room being gone
|
|
from is in R, not if it is equal to R. Similarly for other room-related
|
|
clauses such as "through" and "in".
|
|
</li><li>(c) Given a piece of run-time parser grammar, we compile a test against
|
|
the standard I6 topic variables: there are two of these, so this is the
|
|
exceptional case where the clause doesn't act on a single I6 global,
|
|
and in this case we therefore ignore <span class="extract"><span class="extract-syntax">I6_global_name</span></span>.
