|
|
a mini-language of its own, with a specification closer to traditional
|
|
computer-science norms than Inform's free-wheeling approach — this is not
|
|
an accident. It allows for awkward functional-programming needs in a way
|
|
which vaguer natural language syntax would not.

<p class="commentary firstcommentary"><a id="SP3" class="paragraph-anchor"></a><b>§3. </b>The K-grammar actually has two modes: normal, and phrase-token-mode. Normal
|
|
mode is aptly named: it's almost always the one we're using. Phrase token
|
|
mode is used only when parsing definitions of phrases, like so:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>To repeat with (LV - nonexisting K variable) running from (V1 - arithmetic value of kind K) to (V2 - K)</p>
|
|
</blockquote>
|
|
|
|
<p class="commentary">Here the tokens "nonexisting K variable" and so on are parsed as
|
|
specifications, but in such a way that any kinds mentioned are parsed in
|
|
phrase-token-mode. The difference is that this enables them to refer to kind
|
|
variables such as K which are still being defined; in normal mode, that would
|
|
only be allowed if K already existed.

<p class="commentary firstcommentary"><a id="SP11" class="paragraph-anchor"></a><b>§11. </b>"Object based rulebook" has been on a voyage of unhyphenation: in the early
|
|
public beta of Inform 7, it was "object-based-rulebook" (at that time,
|
|
built-in kinds had to have one-word names); then it became "object-based
|
|
rulebook", when one-word adjectives were allowed to modify the names of
|
|
built-in kinds; and now it is preferably "object based rulebook". But the
|
|
previous syntax is permitted as an alias to keep old source text working. And
|
|
similarly for the others here, except "either-or property", which is a 2010
|
|
addition.
