Using the listings package, I can use deletekeywords to remove keywords, and so the keyword is not rendered in bold. For example, the for from the following is not in bold font:

\lstset{language=[]C++}
\begin{lstlisting}[deletekeywords={for}]
for (int i = 0; i < 8; i++) {}
\end{lstlisting}

This is useful as I like to use the same font for small code snippets within the main body of my text, but don't always want it to appear with keywords in bold. I came up with two commands for convenience:

\newcommand{\code}[1]{\lstinline[deletekeywords=#1]{#1}}
\newcommand{\codeb}[1]{\lstinline[morekeywords=#1]{#1}}

However, with Fortran it doesn't work. The do in the following is still in bold.

\lstset{language=[]Fortran}
\begin{lstlisting}[deletekeywords={do}]
do i = 1,8
end do
\end{lstlisting}

Is there a way to do this? To locally override the keyword/language highlighting settings more generally?

The keyword "DO" is defined as uppercase in lstlang1.sty and the code for Fortran says sensitive=f; so

deletekeywords={DO}

does the trick.

Thanks. I wonder why none of the following work: deletekeywords={\uppercase{do}} or deletekeywords={\MakeUppercase{do}} or deletekeywords={\MakeTextUppercase{do}}. –  user4417 Jul 26 '11 at 12:52
    
Anyway, I noticed that keywordstyle= is also very useful: \newcommand{\code}[1]{\lstinline[keywordstyle=]{#1}} \newcommand{\codeb}[1]{\lstinline[morekeywords=#1]{#1}} –  user4417 Jul 26 '11 at 13:01
    
\uppercase{do} can't work: it transforms "do" into "DO" only at processing time of the string and the string isn't processed at that time. Actually it's more complex than this, marginis exiguitas non caperet. :) Or commenti exiguitas non caperet, more properly. –  egreg Jul 26 '11 at 13:06
