horizontal alignmentparagraphsragged2e
is there a way to right align a text, which is at the same time justified? This particularly points onto the last line of the paragraph, which is normaly left aligned, or for example a very short one line paragraph, which would also appear as left alligned, although it is justified.
Thanks for the help! 🙂
Try
{\raggedleft text\dots \par}
if you want the paragraph aligned to the right.
\documentclass{article}
\begin{document}
Right-aligned wants \verb|\raggedleft|:\par
{\raggedleft text \par}
Left-aligned wants \verb|\raggedright|:\par
{\raggedright text \par}
\end{document}
There is a nice example in The TeXbook to do this. See chapter 14, page 106.
\documentclass{article}
\def\signed #1 (#2){{\unskip\nobreak\hfil\penalty50
\hskip2em\hbox{}\nobreak\hfil\sl#1\/ \rm(#2)
\parfillskip=0pt \finalhyphendemerits=0 \par}}
\begin{document}
\hsize 9cm
This is a case where the name and address fit in nicely with the review.
\signed A. Reviewer (Ann Arbor, Mich.)
But sometimes an extra line must be added. \signed N. Bourbaki (Paris)
\end{document}
You could make it a bit more standard for LaTeX:
\documentclass{article}
\newcommand{\signed}[1]{%
{\unskip\nobreak\hfil\penalty50
\hskip2em\hbox{}\nobreak\hfil#1
\parfillskip=0pt \finalhyphendemerits=0 \par}}
\begin{document}
\hsize 9cm
This is a case where the name and address fit in nicely with the review.
\signed{\emph{A. Reviewer} (Ann Arbor, Mich.)}
But sometimes an extra line must be added. \signed{\emph{N. Bourbaki} (Paris)}
\end{document}
And the explanation of how it works from The TeXbook:
If a line break occurs at the
\penalty50, the\hskip2emwill disappear and the empty\hboxwill occur at the beginning of a line, followed by\hfilglue. This yields two lines whose badness is zero; the first of these lines is assessed a penalty of50. But if no line break occurs at the\penalty50, there will be glue of2 em plus 2 filbetween the review and the name; this yields one line of badness zero. TEX will try both alternatives, to see which leads to the fewest total demerits. The one-line solution will usually be preferred if it is feasible.

The
\leftskipTeX primitive register saves the skip used at each left side of the paragraph line. The skip can be streatchable, for example 0pt plus1fil. The\rightskipTeX primitive register saves the skip used at each right side of the paragraph line. It can be "negative stretachable". It does not mean shrinkable, but it eliminates the positive stretchable amount from\leftskip. The\parfillskipTeX primitive register is set by default (by plain TeX for example) to 0pt plus1fil. It is added at the end of the last line of the paragraph. If we set:then all lines of paragraph (but not the last one) have only
\leftskipat left side and\rightskipat right side. Their sum is zero, so only glu between words are used for justification. The last line have -1fil form\rightskipand 1fil from\parfillskipat right side. Their sum is zero. But there is another 1fil from\leftskip. This skip is stretched and the result is like shown in another answer here. This another answer uses LaTeX specific syntax for setting TeX primitive registers.
