# \hfill doesn't work for braces in mathmode

Hm, something like this:

```
\documentclass{article}
\usepackage{lipsum}
\begin{document}
\lipsum[11]
\par\noindent
$\left.\begin{tabular}{@{} p{\linewidth} @{}}
line \\
one more line
\end{tabular}\right\}$
\par
\lipsum[11]
\end{document}
```

I'd abuse `equation*`

for a couple of reasons:

- automatic vertical spacing around the construction;
- avoiding page breaks before the construction.

The contents of the `braceonright`

environment is typeset as a `tabular`

and reused for getting the right size of the brace. This is neessary, because `\hfill`

does nothing if inside a `\left`

-`\right`

pair.

```
\documentclass{article}
\usepackage{amsmath}
\usepackage{lipsum} % for mock text
\newsavebox{\braceonrightbox}
\newenvironment{braceonright}
{%
\begin{equation*}% abuse equation* for spacing and other features
\hspace{0pt}% necessary
\begin{lrbox}{\braceonrightbox}% save the contents
\begin{tabular}{@{}l@{}}%
}
{%
\end{tabular}%
\end{lrbox}%
\usebox{\braceonrightbox}
\hspace{1000pt minus 1fil}
\left.\vphantom{\usebox{\braceonrightbox}}\right\rbrace
\end{equation*}\ignorespacesafterend
}
\begin{document}
\lipsum[1][1-6]
\begin{braceonright}
line \\
one more line
\end{braceonright}
\lipsum[2]
\end{document}
```

The trick is to add a very large space (1000pt) that can be shrinked to the actual width; in order for this to work, there must be some glue (0pt) at the beginning of the “equation”.
