# Greek and English in lstlisting

I'm trying to create an lstlisting that contains both english and greek letters.

I have set this style.

\lstset{
basicstyle=\normalsize\selectlanguage{english}\ttfamily,  % COURIER NEW?
frame=tb, % draw a frame at the top and bottom of the code block
tabsize=4, % tab space width
showstringspaces=false, % don't mark spaces in strings
numbers=left, % display line numbers on the left
keywordstyle=\color{black}, % keyword color
stringstyle=\color{black} % string color
}


and I want to include this code inside the lstlisting. As you can see there is greek text: 'Σύνθετη Αναζήτηση'. However when i run the pdfLatex compiler, it is rendered in latin character.

\begin{lstlisting}
<?php

function custom_toolbar_link($wp_admin_bar) {$args = array(
'title' => 'Σύνθετη Αναζήτηση',

'meta' => array(
)
);
$wp_admin_bar->add_node($args);
}
\end{lstlisting}


Can you help me?

*** A full minimal example of the text:

\documentclass[11pt,a4paper,fleqn]{article}
\usepackage{listings}
\usepackage{dirtree}
\usepackage{indentfirst}
\usepackage[greek,english]{babel}
\usepackage[iso-8859-7]{inputenc}
\usepackage{chicago}
\usepackage[section]{placeins}

\lstset{
basicstyle=\normalsize\selectlanguage{english}\ttfamily,  % COURIER NEW?
frame=tb, % draw a frame at the top and bottom of the code block
tabsize=4, % tab space width
showstringspaces=false, % don't mark spaces in strings
numbers=left, % display line numbers on the left
keywordstyle=\color{black}, % keyword color
stringstyle=\color{black} % string color
}

% This concludes the preamble
\begin{document}

\begin{lstlisting}[label=some-code,caption=Some Code]
<?php
function custom_toolbar_link($wp_admin_bar) {$args = array(
'title' => 'Σύνθετη Αναζήτηση',
'meta' => array(
)
);
$wp_admin_bar->add_node($args);
}
\end{lstlisting}

\end{document}

• (1) welcome, (2) I know this does not compile, but you are much more likely to get help if you provide a full minimal example instead of sniplets. – daleif Dec 1 '17 at 15:29
• Thank you, I just added a full minimal example of my text. – Spike Dec 1 '17 at 16:02
• Can you use xelatex instead of pdflatex? On my system, your example works well if I remove your inputenc line, and replace it with \usepackage{fontspec}\setmonofont{Courier New}, then compile with xelatex. – Thruston Dec 2 '17 at 11:13
• Thank you for the advice, but I would like to find a way using PDFLaTex. It is matter of compatibility with other files. Instead of article I use a custom class provided from my University, and xelatex doesn't work with it. – Spike Dec 5 '17 at 12:03

You can escape to Latex. for example:

\begin{lstlisting}[label=some-code,caption=Some Code,escapeinside=;;]
<?php
function custom_toolbar_link($wp_admin_bar) {$args = array(
'title' => ';\selectlanguage{greek}Σύνθετη Αναζήτηση\selectlanguage{english};',
$wp_admin_bar->add_node($args);

• Maybe \textgreek{Σύνθετη Αναζήτηση}? Didn't test, though. – egreg Jan 26 '19 at 10:54
