Removing italic formatting from if statement

Question

I would like the if statement to have "current stage" in serif and "satisfies" as normal text. The following code produces both with italics:

\documentclass{article}
\usepackage{algorithm2e}
\begin{document}
\begin{algorithm}

\If{\textsf{current\_state} \textrm{satisfies} \textsf{goal}}
{
return \textsf{existing\_plan}
}
\end{algorithm}
\end{document}

Any ideas?

Answer 1

The algorithm2e package uses \ArgSty to typeset the argument of \If. If you don't want italics, add

\SetArgSty{textup}

Complete example:

\documentclass{article}
\usepackage{algorithm2e}
\SetArgSty{textup}

\begin{document}

\begin{algorithm}
\If{\textsf{current\_state} satisfies \textsf{goal}}
{
return \textsf{existing\_plan}
}
\end{algorithm}

\end{document}

Answer 2

You can use \textup instead of \textrm as suggested by egreg. The code now reads like this:

\documentclass{article}
\usepackage{algorithm2e}
\begin{document}
\begin{algorithm}

\If{\textsf{current\_state} \textup{satisfies} \textsf{goal}}
{
return \textsf{existing\_plan}
}
\end{algorithm}
\end{document}

and the output as required:
