wrapfig within linguex

Question

I'm trying to wrap an image within a linguex bullet, but the image does not compile.

\documentclass{article}
\usepackage{linguex, graphicx, wrapfig}

\begin{document}

\ex. bla bla bla \begin{wrapfigure}{r}{0.5\textwidth}\includegraphics[width=0.5\textwidth]{image}\end{wrapfigure} 

\end{document}

Notice that I need the wrapfigure environment to be on the same line as the \ex. argument, otherwise it wouldn't compile. I feel like that's some sort of incompatibility between the two packages, but does anybody know if there is a way-around?

Thanks!

Answer 1

There are a few solutions around for placing figures in list environments. The following uses the answer published here: Will it ever be possible to use wrapfig with an enumerate or itemize environment?

The only difference is the use of the \ex macro versus the enumerate environment. Quoting from the referenced solution:

It is possible by putting the wrapfigure into a parbox or minipage as is mentioned in some of the duplicates of this question. However those methods usually fix vertical spacing issues by manually inserting \vspace with hand picked values. This solution works automatically by using a strut (\strut). The strut places the baseline of the first text line at a specified distance from the top of the minipage. Then adjustbox is used to place the top of the minipage exactly that amount above the outer baseline.

The MWE and result are as follows:

\documentclass[a4paper,12pt]{article}
\usepackage{linguex, graphicx, wrapfig}
\usepackage[margin=3cm]{geometry}
\usepackage{lipsum}
\usepackage{adjustbox}
\usepackage{capt-of}

\newlength{\strutheight}
\settoheight{\strutheight}{\strut}

\ex. \begin{adjustbox}{valign=T,raise=\strutheight,minipage={1.0\linewidth}}
        \begin{wrapfigure}{r}{0.5\linewidth}
            \centering
            \includegraphics[width=0.5\linewidth]{example-image-a}
            \captionof{figure}{My caption}
        \end{wrapfigure}% 
        \strut{}\lipsum[2]
    \end{adjustbox}

\end{document}

EDIT

This is a response to OP's comment:

Is it then possible to have a figure wrapped in more than one \ex. environment?

I have to guess a bit to interpret what is requested. Here is an interpretation with multiple figures at different levels of environments.

This is the code:

\documentclass[a4paper,10pt]{article}
\usepackage{linguex, graphicx, wrapfig}
\usepackage[margin=3cm]{geometry}
\usepackage{lipsum}
\usepackage{adjustbox}
\usepackage{capt-of}

\newlength{\strutheight}
\settoheight{\strutheight}{\strut}

\ex. \lipsum[2]
\a. \begin{adjustbox}{valign=T,raise=\strutheight,minipage={1.0\linewidth}}
        \begin{wrapfigure}{r}{0.5\linewidth}
            \centering
            \includegraphics[width=0.5\linewidth]{example-image-a}
            \captionof{figure}{My caption}
        \end{wrapfigure}% 
        \strut{}\lipsum[2]
    \end{adjustbox}
\b. \begin{adjustbox}{valign=T,raise=\strutheight,minipage={1.0\linewidth}}
    \begin{wrapfigure}{r}{0.5\linewidth}
        \centering
        \includegraphics[width=0.5\linewidth]{example-image-a}
        \captionof{figure}{My caption}
    \end{wrapfigure}% 
    \strut{}\lipsum[2]
    \end{adjustbox}
    \a. \begin{adjustbox}{valign=T,raise=\strutheight,minipage={1.0\linewidth}}
        \begin{wrapfigure}{l}{0.5\linewidth}
            \centering
            \includegraphics[width=0.5\linewidth]{example-image-a}
            \captionof{figure}{My caption}
        \end{wrapfigure}% 
        \strut{}\lipsum[2]
    \end{adjustbox}
    \b.\lipsum[2]

\end{document}
