Writing some docs with code snippets which I want to be copyable to run as written. These snippets may include lines with preceding spaces. The listings package formats the text fine, but the spaces are not copyable.
Let's say I have the following example:
\documentclass{article}
\usepackage{listings}
\begin{document}
\lstset{
basicstyle=\ttfamily,
frame=single,
columns=fullflexible
}
\begin{lstlisting}[language=python]
def foo():
return "bar"
\end{lstlisting}
\end{document}
If I copy and paste the listing somewhere, it becomes:
def foo():
return "bar"
which must be corrected by hand.
Is there a way to make the listings package include the original spaces? Or is there a package better suited for cases like this?
This is (most likely) not a problem with listings (or latex at all), but with your PDF rendering software. For instance, with PDFKit-based (Preview, Skim, ...) on OSX, I get the behavior that you describe. By using Xpdf, however, the text is copied correctly.

I have searched but nothing useless, only "use \newline" or "use \".
I'm creating a simple latex document to store any texts instead of using .txt, and the problem is that the pdf document contains the lines going towards right until they go out of the paper.
I'm using this simple code
\documentclass[a4paper]{article}
\usepackage{geometry}
\geometry{
a4paper,
total={170mm,257mm},
left=5mm,
top=20mm,
}
\begin{document}
\section{Text 1}

\end{document}
Since latex sees it as a one word, it refuses to break it since it doenst know its hyphenation. But I would like to allow latex to break it regardless. Any thoughts ?
Remarks: I already have used:
\hspace{0pt}
\leavevmode\nobreak\hspace{0pt}
\mbox{Loremip...larorum.}
Nothing worked.
I think I got why nothing worked. See my code below, that I managed to compile successfully after editing your MWE.
You basically have two ways to force hyphenation here.
As in the comment by SamCarter, you manually split words within text, just using \- where necessary. I did it below in line 18 (6 from bottom).
You add to your preamble the command \hyphenation{word-to-split}: I did this below to hyphenate the word in line 20 (4 from bottom). Notice that, in this case, you use - instead of \- within the braces {} enclosing the argument.
\documentclass[a4paper]{article}
\usepackage{geometry}
\geometry{
a4paper,
total={170mm,257mm},
left=5mm,
top=20mm,
}
\hyphenation{Duisauteiruredolorinre-prehenderitinvoluptatevelitesse-cillum doloreeufugiatnullapariatur}
\begin{document}
\section{Text 1}

\end{document}
Finally, if the full stop character . is not followed by a space, two separate words may be interpreted as one and the command \hyphenation may not work as expected. Not sure that this was the detail making you write that nothing worked, but be careful to this too.
How do I combine \afterpage and \endfloat to easily switch between having figures and tables at the end of the document or having them in the text?
I want to easily choose between my figures at the end of the document and my figures in the text. Because of that, sometimes I will use \afterpage package and other times I will use \endfloat would be nice to combine both.
Right now, all the times I try to run \endfloat when I have a clear page, I get the following message:
Argument of \efloat#xfloat has an extra }.
I already tried to include after page in the DeclareDelayedFloatFlavor, something like:
\DeclareDelayedFloatFlavor{afterpage}{figure}
It did not work.
\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{float}
\usepackage{afterpage}
% ---------------------
%figures at the end
% ---------------------
\usepackage[nolists]{endfloat}
% force landscape at the end
\begin{document}
{\afterpage{
\begin{figure}
\end{figure}
}
\end{document}
If you want to switch between having figures within the text and at the end, I suggest to only use the endfloat package. Commenting or commenting it's optional argument disable will allow you to quickly alternate between figures at the end or in the text.
I'm not entirely certain what the purpose of afterpage was in your example, but if you used it to move the figure to a separate page, this can conveniently be done with the p floating specifier.
\documentclass{article}
\usepackage[
disable
]{endfloat}
\begin{document}
test
\begin{figure}[p]
xxx
\caption{caption}
\end{figure}
test
\end{document}
How can I temporarily cause pdfLaTeX to forget everything that I've told it and start with a new document class?
I've modified the example environment from the lshort document:
\newwrite\examplesx#out
\newenvironment{examplesx}{%
\begingroup% Lets Keep the Changes Local
\#bsphack
\immediate\openout \examplesx#out \jobname.exa
\let\do\#makeother\dospecials\catcode`\^^M\active
\def\verbatim#processline{%
\immediate\write\examplesx#out{\the\verbatim#line}}%
\verbatim#start
}{%
\immediate\closeout\examplesx#out\#esphack\endgroup%
\noindent\makebox[\textwidth][l]{%
\begin{minipage}[c]{0.45\textwidth}%
\small\verbatiminput{\jobname.exa}
\end{minipage}%
\hspace*{0.1\textwidth}%
\framebox{%
\begin{minipage}{0.45\textwidth}%
\small\input{\jobname.exa}%
\end{minipage}
}%
}\vspace*{\parskip}%
}
and it mostly works, but I want to be able to do something like
\begin{examplesx}
\section{Section}
\end{examplesx}
and have it show up as a section in a box. I also would like it to typeset lists using the standard article style, even if I use it in beamer
I think that the easiest way of doing this is to compile some small document and then include the resultant pdf as an image into the larger document. Much simpler even if not exactly what you want. I have done this to show, in a Beamer presentation, what LaTeX articles look like.
Of course if its a REALLY simple document (e.g., a simple block of text) that you want to have inside beamer, I could recommend that you mimic the document with a TikZ "picture" that contains some text.
Maybe another approach: instead of trying to typeset things in beamer as if they would be done in article, simply typeset them with the article document class and include the result the in the beamer document.
With tcolorbox this can be done automatically:
% !TeX program = txs:///arara
% arara: pdflatex: {synctex: on, interaction: nonstopmode, shell: yes}
\documentclass{beamer}
\usepackage[most]{tcolorbox}
\begin{document}
\begin{frame}[fragile]
\begin{tcblisting}{
comment only,
pdf comment,
compilable listing,
run pdflatex,
}
\documentclass{article}
\begin{document}
\section{Section Title}
test
\end{document}
\end{tcblisting}
\end{frame}
\end{document}
How do I insert code into a LaTeX document? Is there something like:
\begin{code}## Heading ##
...
\end{code}
The only thing that I really need is indentation and a fixed width font. Syntax highlighting could be nice although it is definitely not required.
Use listings package.
Simple configuration for LaTeX header (before \begin{document}):
\usepackage{listings}
\usepackage{color}
\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}
\lstset{frame=tb,
language=Java,
aboveskip=3mm,
belowskip=3mm,
showstringspaces=false,
columns=flexible,
basicstyle={\small\ttfamily},
numbers=none,
numberstyle=\tiny\color{gray},
keywordstyle=\color{blue},
commentstyle=\color{dkgreen},
stringstyle=\color{mauve},
breaklines=true,
breakatwhitespace=true,
tabsize=3
}
You can change default language in the middle of document with \lstset{language=Java}.
Example of usage in the document:
\begin{lstlisting}
// Hello.java
import javax.swing.JApplet;
import java.awt.Graphics;
public class Hello extends JApplet {
public void paintComponent(Graphics g) {
g.drawString("Hello, world!", 65, 95);
}
}
\end{lstlisting}
Here's the result:
You could also use the verbatim environment
\begin{verbatim}
your
code
example
\end{verbatim}
Here is how to add inline code:
You can add inline code with {\tt code } or \texttt{ code }. If you want to format the inline code, then it would be best to make your own command
\newcommand{\code}[1]{\texttt{#1}}
Also, note that code blocks can be loaded from other files with
\lstinputlisting[breaklines]{source.c}
breaklines isn't required, but I find it useful. Be aware that you'll have to specify \usepackage{ listings } for this one.
Update: The listings package also includes the \lstinline command, which has the same syntax highlighting features as the \lstlisting and \lstinputlisting commands (see Cloudanger's answer for configuration details). As mentioned in a few other answers, there's also the minted package, which provides the \mintinline command. Like \lstinline, \mintinline provides the same syntax highlighting as a regular minted code block:
\documentclass{article}
\usepackage{minted}
\begin{document}
This is a sentence with \mintinline{python}{def inlineCode(a="ipsum)}
\end{document}
Specialized packages such as minted, which relies on Pygments to do the formatting, offer various advantages over the listings package. To quote from the minted manual,
Pygments provides far superior syntax highlighting compared to conventional packages. For example, listings basically only highlights strings, comments and keywords. Pygments, on the other hand, can be completely customized to highlight any token kind the source language might support. This might include special formatting sequences inside strings, numbers, different kinds of identifiers and exotic constructs such as HTML tags.
Minted, whether from GitHub or CTAN, the Comprehensive TeX Archive Network, works in Overleaf, TeX Live and MiKTeX.
It requires the installation of the Python package Pygments; this is explained in the documentation in either source above. Although Pygments brands itself as a Python syntax highlighter, Minted guarantees the coverage of hundreds of other languages.
Example:
\documentclass{article}
\usepackage{minted}
\begin{document}
\begin{minted}[mathescape, linenos]{python}
# Note: $\pi=\lim_{n\to\infty}\frac{P_n}{d}$
title = "Hello World"
sum = 0
for i in range(10):
sum += i
\end{minted}
\end{document}
Output:
Use Minted.
It's a package that facilitates expressive syntax highlighting in LaTeX using the powerful Pygments library. The package also provides options to customize the highlighted source code output using fancyvrb.
It's much more evolved and customizable than any other package!
A very simple way if your code is in Python, where I didn't have to install a Python package, is the following:
\documentclass[11pt]{article}
\usepackage{pythonhighlight}
\begin{document}
The following is some Python code
\begin{python}
# A comment
x = [5, 7, 10]
y = 0
for num in x:
y += num
print(y)
\end{python}
\end{document}
which looks like:
Unfortunately, this only works for Python.
Since it wasn't yet mentioned here, it may be worth to add one more option, package spverbatim (no syntax highlighting):
\documentclass{article}
\usepackage{spverbatim}
\begin{document}
\begin{spverbatim}
Your code here
\end{spverbatim}
\end{document}
Also, if syntax highlighting is not required, package alltt:
\documentclass{article}
\usepackage{alltt}
\begin{document}
\begin{alltt}
Your code here
\end{alltt}
\end{document}
Use Pygments !
I've been looking at Philip Bunge's post on how to create a "Tango" style with LaTeX listings, and trying to adapt this to make the default text style white and the background black (this is for slides, not an article!). This is what I added:
\definecolor{Black}{gray}{0.0}
\definecolor{White}{gray}{0.9}
...
\lstset{
basicstyle=\color{White},
backgroundcolor=\color{Black},
...
}
This assumes that basicstyle sets the default style of all text. The listings documentation says this:
basicstyle is selected at the beginning of each listing. You could use \footnotesize,
\small, \itshape, \ttfamily, or something like that. The last token of must not read any following characters.
The output of this still shows "default" text as black. It is possible to set more style directives that cover most tokens in a given programming language, but even doing this some tokens (such as brackets and other punctuation) will be missed. What did I do wrong?
The following code worked for me, but I converted the .dvi file to a .pdf in order to have the text appear as white, so it might have been your viewer? I'm using xdvi and xpdf.
\documentclass[a4paper, 11pt]{article}
\usepackage{listings}
\usepackage{color}
\definecolor{theWhite}{gray}{0.9}
\definecolor{theBlack}{gray}{0.0}
\lstset { basicstyle=\color{theWhite}, backgroundcolor=\color{theBlack} }
\begin{document}
\begin{lstlisting}
((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))
\end{lstlisting}
\end{document}
I hope that helps!
