<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. Specification of the Neptune language. </b>Everyone loves a mini-language, so here is one. At the top level:
</p>
<ul class="items"><li>(a) Lines consisting of white space or whose first non-white space character is
<span class="extract"><span class="extract-syntax">!</span></span> are ignored as comments.
</li><li>(b) A line ending with a colon <span class="extract"><span class="extract-syntax">:</span></span> opens a new block. The text before the colon
is the title of the block, except that the first character indicates its type:
<ul class="items"><li>(1) An asterisk means that the block is a "star template": for instance,
<span class="extract"><span class="extract-syntax">*PRINTING-ROUTINE:</span></span> says the block defines a template called <span class="extract"><span class="extract-syntax">PRINTING-ROUTINE</span></span>.
A template consists of Inform 7 source text which extends as far as the next
<span class="extract"><span class="extract-syntax">*END</span></span> line.
</li><li>(2) A sharp sign <span class="extract"><span class="extract-syntax">#</span></span> means that the block is a macro definition. For
instance, <span class="extract"><span class="extract-syntax">#UNIT:</span></span> says the block defines a template called <span class="extract"><span class="extract-syntax">UNIT</span></span>. A macro
is just a sequence of lines holding kind commands which continues to
the beginning of the next block, or the end of the file.
</li><li>(3) And otherwise the block is a kind definition, but the optional opening
character <span class="extract"><span class="extract-syntax">+</span></span> marks the kind as one which Inform requires the existence of.
Thus <span class="extract"><span class="extract-syntax">+NUMBER_TY:</span></span>, since Inform will crash if the template doesn't set this
kind up, but <span class="extract"><span class="extract-syntax">BOOJUMS_TY:</span></span> would validly declare a new kind called
<span class="extract"><span class="extract-syntax">BOOJUMS_TY</span></span> which isn't special to any of Inform's internals. The <span class="extract"><span class="extract-syntax">+</span></span> signs
are there as a help for hackers looking at the I6 template and wondering what
they can safely monkey with.
</li></ul>
<li>(c) That just leaves the lines within blocks. Each of these is a usage of one
of the commands, given in the form <span class="extract"><span class="extract-syntax">operation: operand</span></span>, i.e., divided by a
colon and some optional spacing.
</li></ul>
