trivlist: A restricted form of list ¶Synopsis:
\begin{trivlist}
...
\end{trivlist}
A restricted version of the list environment, in which margins are not
indented and an \item without an optional argument produces no
text. It is most often used in macros, to define an environment where
the \item command is part of the environment’s definition. For
instance, the center environment is defined essentially like
this:
\newenvironment{center}
{\begin{trivlist}\centering\item\relax}
{\end{trivlist}}
Using trivlist in this way allows the macro to inherit some
common code: combining vertical space of two adjacent environments;
detecting whether the text following the environment should be
considered a new paragraph or a continuation of the previous one;
adjusting the left and right margins for possible nested list
environments.
Specifically, trivlist uses the current values of the list
parameters (see list), except that \parsep is set to the
value of \parskip, and \leftmargin, \labelwidth,
and \itemindent are set to zero.
This example outputs the items as two paragraphs, except that (by default) they have no paragraph indent and are vertically separated.
\begin{trivlist}
\item The \textit{Surprise} is not old; no one would call her old.
\item She has a bluff bow, lovely lines.
\end{trivlist}
