[OS X TeX] Re: The listings package; pdf or text from pdf searches

[John Maindonald]

I find that if for example I have 'dir()' in code that is used in the
listings environment given below, then using Preview on the
pdf file that results, I have to search for 'd i r ( )', i.e. spaces
must be placed between characters.

I tried pdftotext (a binary xpdf-tools-3.dmg that will install this  
under
MacOS X is available from http://users.phg-online.de/tk/MOSXS/ )

The text appears as 'dir ()', i.e., it removes most of the spaces,
but leaves the space that precedes the '('.

'file.show("travelbooks.txt")'  appears, in the file from pdfotext, as
'file . show ( " travelbooks . txt " )'

I've tried several pdf to text  conversion utilities; all seem to give
much the same result.

Does anyone know of a good way to use the listings package,
and/or some alternative choice of pdf to text conversion software,
that creates a file where the text is searchable pretty much as
one would expect?  Is there a choice of listings options
(a different basicstyle?) that avoids the unwanted spaces?

\definecolor{light}{gray}{.9}
\lstnewenvironment{verbcode}
{\lstset{language=R, xleftmargin=2pt, frame=single, framerule=0pt,
           basicstyle=\ttfamily,
          showstringspaces=false, backgroundcolor=\color{light}}}
{}
