0006 This manual was originally translated from LATEX.HLP v1.0a in the
0007 VMS Help Library.  The pre-translation version was written by
0008 George D. Greenwade of Sam Houston State University.  The
0009 LaTeX 2.09 version was written by Stephen Gilmore.  The
0010 LaTeX2e version was adapted from this by Torsten Martinsen.  Karl
0011 Berry made further updates and additions, and gratefully acknowledges
0012 using Hypertext Help with LaTeX, by Sheldon Green, and
0013 LaTeX Command Summary (for LaTeX 2.09) by
0014 L. Botway and C. Biemesderfer (published by the TeX Users
0015 Group as TeXniques number 10), as reference material.  We also
0016 gratefully acknowledge additional material appearing in
0017 latex2e-reference by Martin Herbert Dietze.  (From these references no

0120 <h4 class="subsection">8.16.2 <code>trivlist</code>: A restricted form of <code>list</code></h4>
0121 
0122 <p>Synopsis:
0123 </p>
0124 <div class="example">
0125 <pre class="example">\begin{trivlist}
0126   ...
0127 \end{trivlist}
0128 </pre></div>
0129 
0130 <p>A restricted version of the list environment, in which margins are not
0131 indented and an <code>\item</code> without an optional argument produces no
0132 text.  It is most often used in macros, to define an environment where
0133 the <code>\item</code> command as part of the environment&rsquo;s definition.  For
0134 instance, the <code>center</code> environment is defined essentially like
0135 this:
0136 </p>
0137 <div class="example">
0138 <pre class="example">\newenvironment{center}
0139   {\begin{trivlist}\centering\item\relax}
0140   {\end{trivlist}}
0141 </pre></div>
0142 
0143 <p>Using <code>trivlist</code> in this way allows the macro to inherit some
0144 common code: combining vertical space of two adjacent environments;
0145 detecting whether the text following the environment should be
0146 considered a new paragraph or a continuation of the previous one;
0147 adjusting the left and right margins for possible nested list
0148 environments.
0149 </p>
0150 <p>Specifically, <code>trivlist</code> uses the current values of the list
0151 parameters (see <a href="list.html#list">list</a>), except that <code>\parsep</code> is set to the
0152 value of <code>\parskip</code>, and <code>\leftmargin</code>, <code>\labelwidth</code>,
0153 and <code>\itemindent</code> are set to zero.
0154 </p>
0155 <p>This example outputs the items as two paragraphs, except that (by
0156 default) they have no paragraph indent and are vertically separated.
0157 </p>
0158 <div class="example">
0159 <pre class="example">\begin{trivlist}
0160 \item The \textit{Surprise} is not old; no one would call her old.
0161 \item She has a bluff bow, lovely lines.
0162 \end{trivlist}
