# sans-serif font in text, monospace serif within algorithm

In my .tex document I use sans-serif font with \sffamily. (And I don't want this to be monospace!)

For my algpseudocode I tried using \texttt. (For I want using a serif monospace font.)

## Please take a look at this minimal example

\documentclass[a4paper,10pt,english]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[a4paper,margin=2.5cm,footskip=0.5cm]{geometry}
\usepackage{algpseudocode}

\title{Example Document}

\begin{document}
\sffamily

\section{some content}
So, that's what my written content looks like. Sans-serif. Pretty nice, eh?

\texttt %When I remove this line, no error at all!

\begin{algorithmic}
\State x = 0
\While{x < 10}
\State x = x+1
\EndWhile
\end{algorithmic}

\sffamily

But for some reason, this doesn't work.

\end{document}


I always keep those errors:

monospace-algorithm.tex:19: Paragraph ended before \text@command was complete. []
monospace-algorithm.tex:19: Too many }'s. []

• What is \text@command?
• I counted the } and the {. Their number seems correct.

• Where do those come from?

• How to make the pseudocode monospace? (I prefer to use standard commands like \sffamily instead of fonts.)
• Unlike \sffamily, which is a switch and affects all text in the group after it, \texttt is a macro that usually only applies to its argument: \texttt{foo} bar. In the example \texttt does not have an argument and that might be problematic. You could go with the switch \ttfamily instead. But I'm quite sure there is a more elegant solution that does not require using all those font commands manually in the document. – moewe Sep 18 '18 at 5:41
• thanx for \ttfamily. unfortunately, it breaks the pseudocode formatting. – Asqiir Sep 18 '18 at 5:47
• You mean the bold? Yes, it is a well-known 'feature' of the default monospace font that it does not come with a bold series. You could try \usepackage{lmodern} where the bold is not very pronounced or look at tex.stackexchange.com/q/215482/35864 – moewe Sep 18 '18 at 5:51

algorithm contains a hook that you can redefine to set the font to a mono-spaced font.

In line with moewe's comment, you can use the lmodern package to get bold mono-spaced font.

% needed for bold tt font
\usepackage[lighttt]{lmodern}
% use sans serif by default
\renewcommand{\familydefault}{\sfdefault}
% use ttfamily for algorithm
\makeatletter
\algrenewcommand\ALG@beginalgorithmic{\ttfamily}
\makeatother


# MWE

Now this works.
