Text beginning with “plus” after ragged2e's commands prevents compilation
Interesting bug. The \Centering
macro ends with \@raggedtwoe@everyselectfont
whose definition is
% ragged2e.sty, line 191:
\newcommand{\@raggedtwoe@everyselectfont}{%
\if@raggedtwoe@spaceskip
\ifdim\fontdimen\thr@@\font=\z@\relax
\spaceskip\z@
\else
\spaceskip\fontdimen\tw@\font
\fi
\else
\spaceskip\z@
\fi
}
Since \spaceskip
is a glue parameter, it will look forward for possible plus
or minus
specifications.
Fix:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{ragged2e}
\usepackage{etoolbox}
\makeatletter
\appto\@raggedtwoe@everyselectfont{\relax}
\makeatother
\begin{document}
\Centering
Plus some random words.
\end{document}
The appended \relax
will stop the search for glue specifications.
It seems that these commands interpret the “plus” as the beginning of a “plus ⟨length⟩ minus ⟨length⟩
” structure to give stretch values to a length. Adding a \relax
appears to solve the problem, here.
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{ragged2e}
\begin{document}
\Centering \relax%
Plus some random words.
\end{document}
Leaving an empty line between the command and the text might also work, but it's less compact in my opinion.
