[texhax] listings options

[Neal H. Walfield]

Hi,

I'm using the listings package to typeset some code.  I have some
short snippets that I'm including inline and some longer examples that
I put in floats.  I want to apply different options to each of these.
For instance, I want the floating listings to have line numbers, but
the inline listings shouldn't.  Further, the inline listings should be
slightly indented, but the floating listings shouldn't be.

I thought I'd do the following:

  \usepackage{listings}
  \newcommand{\lstfloatsettings}{float, numbers=left}
  \newcommand{\lstinlinesettings}{xleftmargin=4ex, xrightmargin=4ex}
  \lstset{
    columns=fullflexible,
    % Don't use visible spaces in strings.
    showstringspaces=false,
    basicstyle=\small,
    captionpos=b,
    frame=single,
  }

But, that doesn't work:

  \begin{lstlisting}[\lstfloatsettings, label=lst:example]
  ...
  \end{lstlisting}

=> 

  ! Package keyval Error: float, numbers=left undefined.
  
  See the keyval package documentation for explanation.
  Type  H <return>  for immediate help.
   ...  

Any ideas or suggestions for a better approach?

Thanks,

Neal
