inlinelisting adds a space after keywords

Question

I am having problem with lstinline macro. It keeps adding a space after the keyword "Module" - see MWE. How could I convince Latex not to do so?

I already tried with including the "." inside the \koda argument, but then I get 2 spaces onward.

\documentclass{book}
\usepackage{listings} 

\newcommand{\koda}[1]{%
\lstinline[language=[Visual]Basic,keywordstyle=\ttfamily\color{blue}, %
basicstyle=\rmfamily\normalsize, prebreak=, %
morekeywords={Or, Loop, Until, To, As, Single, Module, Double, ByVal}]
{#1}} %

\begin{document}
An example with \koda{Console, Sub et Module}. Continued text ...
\end{document}

Thanks in advance!

Answer 1

If you fix your example by adding curly braces around the language and loading xcolor, there aren't any issues with the spacing after the code. But there is still an issue with spacing before: there's an extra space. I've tried taking out spaces and putting in %'s, and nothing seems to fix it. Also, it seems to be specific to [Visual]Basic; if you try [Visual]C++, the extra space goes away. If you delete the language setting within the \lstinline, and use a \lstset{language=[Visual]Basic} outside the \koda definition, the space also goes away. Maybe a bug somewhere in the Visual Basic definition?

\documentclass{book}
\usepackage{xcolor}
\usepackage{listings} 

\newcommand{\koda}{%
  \lstinline[language={[Visual]Basic},
    keywordstyle=\ttfamily\color{blue},
    basicstyle=\rmfamily\normalsize,
    prebreak=,
    morekeywords={Or, Loop, Until, To, As, Single, Module, Double, ByVal}]}

Answer 2

The space before is a bug in lstmisc.sty (2007/02/22 v1.4) in the following "aspect", line 849:

\lst@BeginAspect[keywords,comments]{keywordcomments}
...
\lst@ProvideFamily@@
    \lst@KCAkeywordsB@list\lst@KCAkeywordsB \lst@KC@also
    \lst@gKCAkeywordsB@list\lst@gKCAkeywordsB \lst@KCAWorkB
    {kcb}owo % prefix, other key, working procedure, Output hook
...
\lst@EndAspect

Line 849 should remove the space before the comment:

    {kcb}owo% prefix, other key, working procedure, Output hook

(The next lines without the comment work, because the end of line character 13 (^^M) has catcode 9 for ignore.)

Workaround

If the language is loaded in the preamble, the white space is executed in vertical mode causing no harm:

\lstloadlanguages{[Visual]Basic}
