line-breakingverbatim
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}
I was a little bit surprised to discover that this wasn't already catered for by the fancyvrb package. When using that package, the problem would appear to be because the newline character is defined to be an outer macro, which can't then be gobbled into the verbatim command. So here's a little modification that defines a command \VerbLB which converts newlines into spaces.
\documentclass{article}
\usepackage{fancyvrb}
\makeatletter
\def\VerbLB{\FV@Command{}{VerbLB}}
\begingroup
\catcode`\^^M=\active%
\gdef\FVC@VerbLB#1{%
\begingroup%
\FV@UseKeyValues%
\FV@FormattingPrep%
\FV@CatCodes%
\def^^M{ }%
\catcode`#1=12%
\def\@tempa{\def\FancyVerbGetVerb####1####2}%
\expandafter\@tempa\string#1{\mbox{##2}\endgroup}%
\FancyVerbGetVerb\FV@EOL}%
\endgroup
\makeatother
\begin{document}
Some \VerbLB+text
with+ a line break.
\end{document}
This produces "Some text with a line break." (Given that the line break was inserted by your editor, my guess was that you didn't want it in the output). I've no idea if this breaks anything else! (Well, as it's a new macro it won't break anything, but I've no idea why the new line character was defined as \outer and it may be that there was a very good reason for it.)
Incidentally, I was sorely tempted to comment "Use a better editor". Some editors use soft and hard line breaks and soft ones are only used for display purposes, thus removed when the file is written.
The insertion of an empty item seems to give a better vertical spacing. One can define a myitemize environment that includes this empty item; that will prevent typing it for each description item:
\documentclass{article}
\usepackage{enumitem}
\newenvironment{myitemize}%
{\begin{itemize}\item[]}
{\end{itemize}}
\begin{document}
\begin{description}[style = sameline, leftmargin = 1em]
\item[Animals:]
\begin{itemize}
\item[]
\item Dog
\item Cat
\item Fish
\end{itemize}
\item[Colors:]
\begin{myitemize}
\item Red
\item Green
\item Blue
\end{myitemize}
\end{description}
\end{document}

Package
allttdefines an environemntallttthat uses a list environment internally. Therefore it cannot be used the same way as\verbor\texttt.The main point of package
allttis the unchanged use of\,{and}. The following macro\textallttsets verbatim catcodes for its argument except for the three characters.
