<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. </b>A typical example would be:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>Definition: A container is roomy if its carrying capacity is 10 or more.</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">Here the domain of the definition is "container", and we must assign
|
|
an adjective meaning for "roomy" which involves the comparison of a
|
|
property (here "carrying capacity") against a threshold value \(t\) (here,
|
|
\(t=10\)). Each such definition allows the property value to belong to a
|
|
"region": we are looking for membership of \(\lbrace x\mid x\leq t\rbrace\),
|
|
\(\lbrace t\rbrace\) or \(\lbrace x\mid x\geq t\rbrace\). The following constants
|
|
enumerate the possible shapes of this region.

<p class="commentary firstcommentary"><a id="SP2" class="paragraph-anchor"></a><b>§2. </b>We then need to create the comparative form "roomier" as a relation, and the
|
|
superlative "roomiest" as a phrasal form — not in general an adjective, since
|
|
its domain is too ambiguous in text such as:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>if the canvas bag is roomiest, ...</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">which begs the question: roomiest out of what? All containers, or implicitly
|
|
some subcollection of them? So we avoid the problem by allowing superlatives
|
|
only when explicitly followed by a domain:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>roomiest container in Heathrow Terminal 5</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">The word "roomy" is the headword, so called in the lexicography sense —
|
|
other forms are derived from it but they all appear under "roomy" in
|
|
the Phrasebook.

|
|
<p class="commentary firstcommentary"><a id="SP3" class="paragraph-anchor"></a><b>§3. </b>The implementation of measurement adjectives is tricksy for reasons of
|
|
timing during Inform's run: the names of kinds, properties and values become
|
|
available at different times; whereas we need the name of the adjective
|
|
itself to become available very early on. This is why the structure below
|
|
appears to record a lot of extraneous clutter apparently needed only
|
|
temporarily during parsing — because parsing does not happen all at once,
|
|
and partial results have to be parked in the structure after one stage to
|
|
be picked up at the next.

<p class="commentary firstcommentary"><a id="SP10_2" class="paragraph-anchor"></a><b>§10.2. </b>Perhaps this is a good point to say why we allow any exact measurements at
|
|
all. After all, if we didn't, a definition like:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>Definition: a person is handy if his carrying capacity is 7.</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">...would still work; and "handy" would then be created as a <span class="extract"><span class="extract-syntax">CONDITION_KADJ</span></span>
|
|
adjective. So why not let that happen?
|
|
</p>
|
|
|
|
<p class="commentary">The answer is that our <span class="extract"><span class="extract-syntax">MEASUREMENT_KADJ</span></span> adjectives behave exactly the same
|
|
at run-time, but can also be asserted true in the model world at compile-time.
|
|
In particular, we could write:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>Peter is a handy person.</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">This can't be done with general <span class="extract"><span class="extract-syntax">CONDITION_KADJ</span></span> adjectives, because conditions

can't normally be unravelled at compile time.
