Highlighting a line in program listings in lyx

I am not able to find how i can highlight a particular line of code in program listings.
Syntax highlighting seems to work but I dont need particular language keywords to be highlighted.
e.g.
for the code below how can i highlight/bold face char j=malloc......line
public static void function(){
int i=0;
char j = malloc(sizeof(char));
/.......some code....
return;
}

Welcome to TeX.SX! Do you know the packagelistings
? I am sure, there is support for this inlyx
too. You should be more specific and provide a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting withdocumentclass{...}
and ending withend{document}

@ChristianHupfer LyX useslistings
by default when one does Insert --> Program listing, so the question is more how to this withlistings
, in LyX.

@ChristianHupfer What i know is listings package is by default installed in lyx 2.0.6 but highlighting a particular line of code to show it as an interesting event in program listing is not mentioned afaik

Idea: one could use LaTeX escape in the listing: somehow, you need to addescapechar=@
(or perhaps another character, remembering to escape special ones) and then issue a@color{blue}@
at the beginning of the line you wish to highlight. Can't test right now though...

Like this:
documentclass[12pt]{article}
usepackage{listings}
usepackage{xcolor}
newcommand{hilight}{makebox[0pt][l]{%
color{yellow}rule[-4pt]{0.65linewidth}{14pt}}%
}
begin{document}
begin{lstlisting}[language=C,escapechar=%]
public static void function(){
int i=0;
%hilight%char j = malloc(sizeof(char));
/.......some code....
return;
}
end{lstlisting}
end{document}
Adapted from an answer by Juanjo on latex-community.org.
You can see the result on writeLaTeX.
To achieve the same result in LyX, go to Document->Settings
and navigate to the Preamble
tab. Paste everything from usepackage{listings}
to the end of the begin{document}
block into the preamble and save it.
To insert the program listing into the document, go to Insert -> Program Listing
in the menu. Paste the code into the listing environment. Then hold Ctrl
and right-click on the environment and open the Settings
dialog. Go to the Advanced
tab in the dialog and paste escapechar={%}
into the text area. Configure the other settings however you want them to look.
There is an example LyX file you can download [here]
(https://dl.dropbox.com/s/9dfqtsc0fnftggc/hilite_example.lyx).
thanks for the example but actually i am looking for a way in which i can do the line highlighting while working on lyx document itself. I think i am too lazy to edit the latex document for it, that is the whole purpose of using lyx afaik. Please correct me if I am wrong.

I gave you the whole document to (hopefully) make it clear where everything goes, but there is no reason not to do this in LyX. Put the stuff beforebegin{document}
in your preamble and thebegin{lstlisting}...end{lstlisting}
part in a LaTeX box within your document.

Welcome to TeX.SX! Do you know the package
listings
? I am sure, there is support for this inlyx
too. You should be more specific and provide a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting withdocumentclass{...}
and ending withend{document}

listings
by default when one does Insert --> Program listing, so the question is more how to this withlistings
, in LyX.– Torbjørn T.

lyx

@ChristianHupfer What i know is listings package is by default installed in lyx 2.0.6 but highlighting a particular line of code to show it as an interesting event in program listing is not mentioned afaik
– dsingh
Aug 26 '14 at 20:23
Idea: one could use LaTeX escape in the listing: somehow, you need to add
escapechar=@
(or perhaps another character, remembering to escape special ones) and then issue a@color{blue}@
at the beginning of the line you wish to highlight. Can't test right now though...– Sean Allred
