<h3>How to reduce list spacing</h3>
<p><a href="FAQ-books.html">Lamport's book</a> lists various
parameters for the layout of list (things like <code>\</code><code>topsep</code>,
<code>\</code><code>itemsep</code> and <code>\</code><code>parsep</code>), but fails to mention that they're set
automatically within the list itself. It works by each list executes
a command <code>\</code><code>@list</code><code><<i>depth</i>></code> (the depth appearing as a
lower-case roman numeral); what's more, <code>\</code><code>@listi</code> is usually reset
when the font size is changed. As a result, it's rather tricky for
the user to control list spacing; of course, the real answer is to use
a document class designed with more modest list spacing, but we all
know such things are hard to come by. The <i>memoir</i> class wasn't
designed for more compact lists <em>per se</em>, but offers the user
control over the list spacing.
<p>There are packages that provide some control of list spacing, but they
seldom address the separation from surrounding text (defined by
<code>\</code><code>topsep</code>). The <i>expdlist</i> package, among its many controls
of the appearance of <code>description</code> lists, offers a
compaction parameter (see the documentation); the <i>mdwlist</i>
package offers a <code>\</code><code>makecompactlist</code> command for users' own list
definitions, and uses it to define compact lists
<code>itemize*</code>, <code>enumerate*</code> and
<code>description*</code>. In fact, you can write lists such as
these commands define pretty straightforwardly - for example:
<blockquote>
<pre>
\newenvironment{itemize*}%
{\begin{itemize}%
\setlength{\itemsep}{0pt}%
\setlength{\parskip}{0pt}}%
{\end{itemize}}
</pre>
</blockquote>
The <i>paralist</i> package provides several approaches to list
compaction:
<ul>
<li> its <code>asparaenum</code> environment formats each item as if
it were a paragraph introduced by the enumeration label (which saves
space if the item texts are long);
<li> its <code>compactenum</code> environment is the same sort of
compact list as is provided in <i>expdlist</i> and
<i>mdwlist</i>; and
<li> its <code>inparaenum</code> environment produces a list "in
the paragraph", i.e., with no line break between items, which is a
great space-saver if the list item texts are short.
</ul>
The package will manipulate its <code>enumerate</code> environment
labels just like the <a href="FAQ-enumerate.html"><i>enumerate</i> package</a>
does.
<p><i>Paralist</i> also provides <code>itemize</code> equivalents
(<code>asparaitem</code>, etc.), and <code>description</code>
equivalents (<code>asparadesc</code>, etc.).
<p>The ultimate in compaction (of every sort) is offered by the
<i>savetrees</i> package; compaction of lists is included. The
package's prime purpose is to save space at every touch and turn:
don't use it if you're under any design constraint whatever!
<p>The <i>expdlist</i>, <i>mdwlist</i> and <i>paralist</i>
packages all offer other facilities for list configuration: you should
probably not try the "do-it-yourself" approaches outlined below if
you need one of the packages for some other list configuration
purpose.
<p>For ultimate flexibility (including manipulation of <code>\</code><code>topsep</code>), the
<i>enumitem</i> package permits adjustment of list parameters using
a "<em>key</em>=<<i>value</i>>" format; so
for example, one might write
<blockquote>
<pre>
\usepackage{enumitem}
...
\begin{enumerate}[topsep=0pt, partopsep=0pt]
\item ... ...
\end{enumerate}
</pre>
</blockquote>
to suppress all spacing above and below your list. <i>Enumitem</i>
also permits manipulation of the label format in a more "basic"
manner than the <a href="FAQ-enumerate.html"><i>enumerate</i> package</a> does.
