[Tex/LaTex] How to change listing caption

algorithmscaptionslistingspseudocode

I have some listings that contain pseudo-code of algorithms. And I use this:
\lstset{caption={Descriptive Caption Text},label=DescriptiveLabel}
to add captions to them.

My problem is that the caption at the created file shows
Listing 1: Descriptive Caption Text. I would like it to write
something like Algorithm 1: Descriptive Caption Text.

How can this be done?

The following modifications are what you're after:

\renewcommand{\lstlistingname}{Algorithm}% Listing -> Algorithm
\renewcommand{\lstlistlistingname}{List of \lstlistingname s}% List of Listings -> List of Algorithms

enter image description here

\documentclass{article}
\usepackage{listings}% http://ctan.org/pkg/listings
\renewcommand{\lstlistingname}{Algorithm}% Listing -> Algorithm
\renewcommand{\lstlistlistingname}{List of \lstlistingname s}% List of Listings -> List of Algorithms
\begin{document}
\lstlistoflistings

\begin{lstlisting}[caption={Descriptive Caption Text},label=DescriptiveLabel]
for i:=maxint to 0 do
begin
{ do nothing }
end;
Write('Case insensitive ');
WritE('Pascal keywords.');
\end{lstlisting}

\end{document}

The example was taken directly from the listings documentation.

Solution

Do not mix lst: with Algorithm floats. The previous solution used \newcommand{\algorithmname}{Listing}, but this could result in LaTeX Error: Command \algorithmname already defined. Instead, apply the following changes:

Rename lst: to alg:.

Change the preamble to:

\usepackage{float}
\floatname{algorithm}{Listing}
\renewcommand{\algorithmname}{Listing}

This does not change the "List of Algorithms" to "List of Listings". The text is found in "stdfloats.inc":

Float
    Type                  algorithm
    GuiName               Algorithm
    Placement             tbp
    Extension             loa
    NumberWithin          none
    Style                 ruled
    ListName              "List of Algorithms"
    LaTeXBuiltin          false
End

The improper way to fix this is:

Edit stdfloats.inc.
Change "List of Algorithms" to "List of Listings".
Click Tools >> Reconfigure.
Restart LyX.

At this point, "List of Algorithms" will read "List of Listings".

[Tex/LaTex] Invisible listing captions

The package listings also provide an optional argument of caption. So simple use:

\begin{lstlisting}[caption={[entry]}]

This way is also described in the documentation at page 32.

The complete example.

\documentclass{article}
\usepackage{listings}

\begin{document}
\lstlistoflistings

\section{This is my section}
\begin{lstlisting}[caption={[foo]}]
 for i:=maxint to 0 do
 begin
 { do nothing }
 end;
\end{lstlisting}


\end{document}
