<p class="purpose">What to do to make use of the inflections module in a new command-line tool.</p>
<ul class="toc"><li><a href="P-htitm.html#SP1">&#167;1. Status</a></li><li><a href="P-htitm.html#SP2">&#167;2. Importing the module</a></li><li><a href="P-htitm.html#SP3">&#167;3. Using callbacks</a></li></ul><hr class="tocbar">
<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. Status. </b>The inflections module is provided as one of the "services" suite of modules,
which means that it was built with a view to potential incorporation in
multiple tools. It can be found, for example, in <a href="../inform7/index.html" class="internal">inform7</a> and
<a href="../inflections-test/index.html" class="internal">inflections-test</a>.
</p>
<p class="commentary">By convention, the modules considered as "services" have no dependencies on
other modules except for <a href="../../../inweb/docs/foundation-module/index.html" class="internal">foundation</a> and other "services" modules.
</p>
<p class="commentary">A tool can import <a href="index.html" class="internal">inflections</a> only if it also imports <a href="../../../inweb/docs/foundation-module/index.html" class="internal">foundation</a>,
<a href="../words-module/index.html" class="internal">words</a> and <a href="../syntax-module/index.html" class="internal">syntax</a>.
</p>
<p class="commentary firstcommentary"><a id="SP2" class="paragraph-anchor"></a><b>&#167;2. Importing the module. </b>We'll use the term "parent" to mean the tool which is importing <a href="index.html" class="internal">inflections</a>,
that is, which will include its code and be able to use it. As with any
imported module,
</p>
<ul class="items"><li>&#9679; The contents page of the parent's web must identify and locate the
module:
</li></ul>
<pre class="displayed-code all-displayed-code code-font">
<span class="element-syntax">Import</span><span class="plain-syntax">:</span><span class="string-syntax"> somepath/inflections</span>
</pre>
<ul class="items"><li>&#9679; The parent must call <span class="extract"><span class="extract-syntax">InflectionsModule::start()</span></span> just after it starts up, and
<span class="extract"><span class="extract-syntax">InflectionsModule::end()</span></span> just before it shuts down. (But just after, and just
before, the corresponding calls to <a href="../../../inweb/docs/foundation-module/index.html" class="internal">foundation</a>.)
</li></ul>
<p class="commentary firstcommentary"><a id="SP3" class="paragraph-anchor"></a><b>&#167;3. Using callbacks. </b>Shared modules like this one are tweaked in behaviour by defining "callback
functions". This means that the parent might provide a function of its own
which would answer a question put to it by the module, or take some action
on behalf of the module: it's a callback in the sense that the parent is
normally calling the module, but then the module calls the parent back to
ask for data or action.
</p>
<p class="commentary">This module has only one callbacks and it is optional:
</p>
<ul class="items"><li>&#9679; <span class="extract"><span class="extract-syntax">VC_COMPILATION_LINGUISTICS_CALLBACK</span></span>, if provided, allows the <span class="extract"><span class="extract-syntax">compilation_data</span></span>
part of a <span class="extract"><span class="extract-syntax">verb_conjugation</span></span> to be initialised. See <a href="3-vc.html#SP6" class="internal">Conjugation::conjugate</a>.
