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".

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.

name ("Raffles") from the action itself ("taking a jewel"), and all

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

without an initial actor name, that takes priority, to ensure that this

actorless possibility can always be written.

<p class="commentary firstcommentary"><a id="SP14" class="paragraph-anchor"></a><b>§14. </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>
|
|
|
|
<p class="commentary">where "doing it" will refer to "taking the box". But I wonder if the
|
|
possibility for confusion is too great; perhaps we should just cut this idea.

now, but what's left can't very efficiently be written in Preform. Essentially
|

we apply <action-list> to the text and then parse the operands using
|
|
<action-operand>, though it's a bit more involved because we also recognise
|
|
optional suffixes special to individual actions, like the "from the cage" in
|
|
"exiting from the cage", and we fail the result if it produces
|

inconsistencies between alternative actions (e.g., "taking or waiting the

box" makes no sense since only one is transitive).

|
|
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.
