Text Formatting ⇒ narrow paragraph

[iranacre]

Hi all,

I was wondering how to make a narrow paragraph in a text and found a command \narrower. I couldn't find any description to this command but it seems to make paragraph narrower by value of \parindent variable. Any idea how to change this value?

Thanks!

Hi,

in the following code I used a list to create an environment mypar that let's you control the nargins for your paragraphs:

Code: Select all

\documentclass{article}
\usepackage{lipsum}% just to automatically generate some text

\newenvironment{mypar}[2]
  {\begin{list}{}%
    {\setlength\leftmargin{#1}
    \setlength\rightmargin{#2}}
    \item[]}
  {\end{list}}

\begin{document}

\lipsum[1]
\begin{mypar}{1cm}{1cm}
\lipsum[1]
\end{mypar}
\lipsum[1]
\begin{mypar}{0cm}{2cm}
\lipsum[1]
\end{mypar}
\lipsum[1]
\begin{mypar}{2cm}{0cm}
\lipsum[1]
\end{mypar}
  
\end{document} 

P.S.: the \parindent value can be changed using \setlength, for example:

Code: Select all

\setlength\parindent{0em}

Thanks, I'm using it in \newenvironment too. So, for me there's no problem to redefine \parindent variable and use \narrower. I just wanted to see any definition of the command.

Here's the definition (from latex.ltx):

Code: Select all

\def\narrower{%
  \advance\leftskip\parindent
  \advance\rightskip\parindent}
