# Indent textblock but not first line

the regular behaviour is that a new textblock gets indent on the first line. Which is great.

But I want for certain textblock (not default for the whole document) the exact opposite behaviour. Meaning the first line should not get indent, but all the lines below.

Like shown here:

Lorem ipsum dolor sit amet, consectetur adipisicing elit,
sed do eiusmod tempor incididunt ut labore et dolore
magna aliqua. Ut enim ad minim veniam, quis nostrud
exercitation ullamco laboris nisi ut aliquip ex ea
commodo consequat.


is it somehow possible? I'm using \documentclass{scrbook} if it matter.

Update: please note that my first line contains a \paragraph headline.

E.g.:

\documentclass{scrbook}
\usepackage{lipsum}
\begin{document}
\lipsum[1]

\paragraph{my paragraph} \lipsum[2]

\lipsum[3]
\end{document}

Paragraph shapes can be changed using the \parshape primitive:

\documentclass{scrbook}

\usepackage[nopar]{lipsum}

\begin{document}

\lipsum[1]

\paragraph{Some paragraph heading}
\parshape % Change the shape of the following paragraph
2 % Identify the shape by specying 2 lines
0pt \linewidth % First line has a left indent of 0pt and a width of \linewidth
\parindent \dimexpr\linewidth-\parindent % Second (and subsequent lines) have an indent of \parindent
% and a width of \linewidth-\parindent
\lipsum[2]  % Set paragraph with new paragraph shape

\lipsum[3]

\end{document}


We change the \parshape after initiating the \paragraph heading.

\documentclass{scrbook}
\usepackage{lipsum}
\parskip=1em
\begin{document}
\lipsum[1]

{\leftskip=\parindent
\parindent=-\leftskip
\lipsum[2]}

\lipsum[3]
\end{document}


FOLLOW UP

For a \paragraph starter: add the line \expandafter\def\csname scr@paragraph@sectionindent\endcsname{-\dimexpr\svparindent\relax} into the mix, after previously saving the default \parindent in \svparindent.

\documentclass{scrbook}
\usepackage{lipsum}
\usepackage[T1]{fontenc}
\edef\svparindent{\the\parindent}
\begin{document}
\lipsum[1]

{\leftskip=\parindent
\parindent=-\leftskip
\expandafter\def\csname scr@paragraph@sectionindent\endcsname{-\svparindent}%
\paragraph{my paragraph} \lipsum[2]
}

\lipsum[3]
\end{document}


• thx. the result looks exactly how I want to have it. BUT the \parskip=1em increases the vertical distance between ALL textblocks as well. Do you know how to avoid this? Jul 21 '17 at 18:27
• @user2798895: That was most likely just to highlight the difference by adding some separation between the paragraphs. You don't need to change \parskip in your application. Jul 21 '17 at 18:28
• @user2798895 What he said ^^^. Jul 21 '17 at 18:29
• sorry I mixed up parskip and parindent while reading. Your sample is working very well. But my code has a paragraph.Having this, your answer is not working anymore. Do you know how it will work for this as well? (I updated the question) Jul 21 '17 at 18:36
• @user2798895 Please see my edit. Jul 21 '17 at 18:49

The hanging package is pretty good - and easy

\documentclass{article}
\usepackage{hanging}

\begin{document}

\hangpara{3em}{-3}You can also use the hanging macro directly from the package if don't want my autowidth eg several hangs of the same width
hangpara is called as width and then a positive value indents the left a negative intends at the right of the text
The second parameter is nthe number of lines toi indent . If positive, then the lines after N will be indented. If negative the first N lines will be indented.
NB Must be no linebreak between hangpara command and the text (or use a percent sign)

\bigskip

\hangpara{3em}{3}You can also use the hanging macro directly from the package if don't want my autowidth eg several hangs of the same width
hangpara is called as width and then a positive value indents the left a negative intends at the right of the text
The second parameter is nthe number of lines toi indent . If positive, then the lines after N will be indented. If negative the first N lines will be indented.
NB Must be no linebreak between hangpara command and the text (or use a percent sign)

\bigskip

\hangpara{8em}{-1}You can also use the hanging macro directly from the package if don't want my autowidth eg several hangs of the same width
hangpara is called as width and then a positive value indents the left a negative intends at the right of the text

• its definitely the best readable version. But its not working anymore when using a \paragraph within the textblock. (like the update I added yesterday) Jul 22 '17 at 16:23
