resultwizard 0.1

TL;DR: You have an old version of siunitx. Please update it or use the siunitx_fallback option in the config_init method.

In version v3.1.0 (2022-04-25), siunitx introduced "support for multiple uncertainty values in both short and long form in input". We make use of this feature in ResultWizard.

Unfortunately, it may be the case that you're using an older version of siunitx. Especially if you've installed LaTeX via a package manager (e.g. you installed siunitx via sudo apt install texlive-science). To determine your version, include the following line in your LaTeX document:

\listfiles % add this before \begin{document}

Then, compile your document and check the log for the version of siunitx. If it's older than v3.1.0 (2022-04-25), don't despair. We have two solutions for you:

Solution 1: Don't update siunitx and stick with your old version

Sure, fine, we won't force you to update siunitx (although we'd recommend it). To keep using your old version, specify the following key in the config_init method:

wiz.config_init(siunitx_fallback=True)

Note that with this "solution", you won't be able to fully customize the output of the result in your LaTeX document. For example, we will use a ± between the value and the uncertainty, e.g. 3.14 ± 0.02. You won't be able to change this in your sisetup by doing:

\sisetup{separate-uncertainty=false}

to get another format like 3.14(2). There are also some other siunitx options that won't work with ResultWizard, e.g. exponent-product. If you're fine with this, go ahead and use the siunitx_fallback option. If not, consider updating siunitx to at least version v3.1.0.

Solution 2: Update siunitx (recommended)

How the update process works depends on your LaTeX distribution and how you installed it. E.g. you might be using TeX Live on Ubuntu and installed packages via apt, e.g. sudo apt install texlive-science (which includes the LaTeX siunitx). These pre-built packages are often outdated, e.g. for Ubuntu 22.04 LTS (jammy), the siunitx package that comes with the texlive-science package is 3.0.4. Therefore, you might have to update siunitx manually. See an overview on how to install individual LaTeX packages on Linux here.

A quick solution might be to simply install a new version of siunitx manually to your system. There's a great and short Ubuntu guide on how to install LaTeX packages manually here. The following commands are based on this guide. We will download the version 3.1.11 (2022-12-05) from GitHub (this is the last version before 3.2 where things might get more complicated to install) and install it locally. Nothing too fancy. Execute the following commands in your terminal:

# Install "unzip", a tool to extract zip files
sudo apt install unzip

# Download v3.1.11 of siunitx from GitHub
curl -L https://github.com/josephwright/siunitx/releases/download/v3.1.11/siunitx-ctan.zip > siunitx-ctan-3.1.11.zip

# Unzip the file
unzip ./siunitx-ctan-3.1.11.zip
cd siunitx/

# Run LaTeX on the .ins file to produce a usable .sty file
# (The .sty file is needed when you use \usepackage{siunitx}
# in your LaTeX document)
latex siunitx.ins

# Create a new directory in your home directory
# to store the new package .sty file
mkdir -p ~/texmf/tex/latex/siunitx
cp siunitx.sty ~/texmf/tex/latex/siunitx/

# Make LaTeX recognize the new package by pointing it to the new directory
texhash ~/texmf/

# 🙌 Done. Try to rebuild your LaTeX document again.

# If you don't wan't the new siunitx version anymore, just run the following
# command to remove the .sty file. LaTeX will then use the version of siunitx
# it finds somewhere else in your system.
rm ~/texmf/tex/latex/siunitx/siunitx.sty

Compiling your latex document again, you should see version v3.1.11 of siunitx in the log file. And it should build, yeah 🎉. Don't forget to remove the \listfiles from your LaTeX document to avoid cluttering your log file (which is ironic for LaTeX, we know).
