# alltt package's \alltt{} makes a newline

alltt causes a line break (newline). How do i suppress this? I want something to the effect of \verb+HELLO+ in that it does what \begin{verbatim} \end{verbatim} does except doesn't cause the line to break.

 \documentclass{article}
\usepackage{alltt}

\begin{document}

The line will break HERE: \alltt{a}

\end{document}

alltt should be used as an environment. You probably want \texttt{a}. – egreg Sep 8 '12 at 7:53
Can you make a real example of usage? – egreg Sep 8 '12 at 8:03

Package alltt defines an environemnt alltt that uses a list environment internally. Therefore it cannot be used the same way as \verb or \texttt.

The main point of package alltt is the unchanged use of \, { and }. The following macro \textalltt sets verbatim catcodes for its argument except for the three characters.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}

\makeatletter
\newcommand*{\textalltt}{}
\DeclareRobustCommand*{\textalltt}{%
\begingroup
\let\do\@makeother
\dospecials
\catcode\\=\z@
\catcode\{=\@ne
\catcode\}=\tw@
\verbatim@font\@noligs
\@vobeyspaces
\frenchspacing
\@textalltt
}
\newcommand*{\@textalltt}[1]{%
#1%
\endgroup
}
\makeatother

\begin{document}
Verbatim text: \textalltt{Hello \textbf{\textsl{world}}}.
\end{document}
