How to make this work with 2-column documents about jlcode

[wg030]

With my update from yesterday I did exactly what I described above and intended to do.

You don't even need a minipage anymore. The package should work with two (or even more) column documents automatically now.

Well, this is tricky because switchting between one column and two columns is always not that easy.
Usually you would most likely go with the multicol package in that case. However if you are kind of restricted by a template that is a twocolumn documentclass, the best way I can think of is something like this:

\documentclass[twocolumn, 11pt, a4paper]{scrartcl}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{lipsum}
\usepackage{jlcode}

\begin{document}
\noindent
\lipsum[1-1][1-8]
\noindent
\begin{figure*}[htbp]
\begin{minipage}{\textwidth}
{\small
\begin{jllisting}
using DynamicalSystems
# some input data (chaotic Roessler system)
ds = Systems.roessler()
X  = trajectory(ds, 1000.0; Ttr = 1e3)
# Estimate correlation sum
es = estimate_boxsizes(X) # Sect. IV. A
Cs = boxed_correlationsum(X, es; q = 2)
# find and fit linear region
_, Delta = linear_region(log.(es), log.(Cs))
\end{jllisting}
}
\end{minipage}
\end{figure*}
\noindent
\lipsum[1-1][9-40]
\lipsum[2-9]
\end{document}

However, note that the listing is now a floating object and hence will be placed where the compiler thinks it fits best. I a two column document this is probably the top or the button of a page for short listings and a single page alone for long listings with a lot of lines of code.

Hi @Datseris,
this looks ugly, of course. Could you provide the code for a complete minimal working example so that I can reproduce this problem?!

Hi,

I am using the Chaos AIP template. Nevertheless something tells me this doesn't depend on the template and would be the same for any dual column document. I'm a bit busy now, when I have some spare time I can try to create a MWE. When I first posted this I was hoping whether there was some simple option I've missed...

[wg030]

Well, it seems as if nobody has ever used that package in a two column document so far.
However, testing it with the scrartcl and the twocolumn option I could indeed easily create the same issue which means your guess that this has nothing to do with your template is very likely correct.
The good news is that it is as easy to fix: Just embed your listing into a minipage like this:

\documentclass[twocolumn, 11pt, a4paper]{scrartcl}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{lipsum}
\usepackage[charsperline=45]{jlcode}

\begin{document}
\noindent
\lipsum[1-1][1-8]
\noindent
\begin{minipage}{\columnwidth}
{\small
\begin{jllisting}
using DynamicalSystems
# some input data (chaotic Roessler system)
ds = Systems.roessler()
X  = trajectory(ds, 1000.0; Ttr = 1e3)
# Estimate correlation sum
es = estimate_boxsizes(X) # Sect. IV. A
Cs = boxed_correlationsum(X, es; q = 2)
# find and fit linear region
_, Delta = linear_region(log.(es), log.(Cs))
\end{jllisting}
}
\end{minipage}
\noindent
\lipsum[1-1][9-40]
\lipsum[2-4]
\end{document}

Note how I used the charsperline option to control the size of the codebox and how I also made use of the automatic font adjustment simply using \small in order to make the code fit into the column.
I also already know how to get rid of the minipage for the next future update which I am already working on and I will release soon. One simply needs to replace all \textwidth by \columnwidth in the jlcode.sty file and then everything should work even without a minipage.

Wow, thanks @wg030 for the fast problem identification and fix!

Hi, @wg030 , so the issue is now fixed! I came here with more like a question instead of opening a new issue, as I don't think this is an issue. My situation now is that I have a 2 column document, but my code is large. So I want to have a code using jlcode that spans two columns instead of one. Is this possible?
