Output

The error you're encountering is likely due to how LaTeX handles newlines in captions, especially when working with packages that deal with hyperlinks and references, such as `hyperref`. In LaTeX, using `\\` directly in captions can lead to issues because of how the `caption` package processes the input. To avoid these issues, you can use the `\newline` command or `\protect` the `\\` command within the caption. Alternatively, you can use a more robust approach with the `caption` package's features. Here's how you can do it: 1. **Using `\newline`:** 

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
   \documentclass{article}
   \usepackage{caption}
   \usepackage{hyperref}

   \begin{document}
   \begin{figure}
       \caption{First line\newline Second line}
       \includegraphics{example-image}
   \end{figure}
   \end{document}
2. **Using `\protect\\`:**

 9
10
11
   \documentclass{article}
   \usepackage{caption}
   \usepackage{hyperref}

   \begin{document}
   \begin{figure}
       \caption{First line\protect\\ Second line}
       \includegraphics{example-image}
   \end{figure}
   \end{document}
3. **Using the `caption` package's `\\` support:** The `caption` package provides support for line breaks in captions. Ensure you have the `caption` package loaded: 
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
   \documentclass{article}
   \usepackage{caption}
   \usepackage{hyperref}

   \captionsetup{format=plain} % This can help with compatibility

   \begin{document}
   \begin{figure}
       \caption{First line\\ Second line}
       \includegraphics{example-image}
   \end{figure}
   \end{document}
In these examples, the `\newline` and `\protect\\` commands help ensure that the caption is processed correctly without causing an error. The third approach relies on the `caption` package's built-in support for line breaks. Choose the method that best fits your needs and the specific setup of your LaTeX document.

Output

In LaTeX, using `\\` directly in a caption can indeed cause issues, particularly with packages such as `hyperref` that handle hyperlinks and references. The error message you encountered, mentioning `\Hy@tempa`, is related to this conflict. To safely insert a line break in a caption, you should use the `\newline` command instead of `\\`. Here's an example of how to do it: 

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
\documentclass{article}
\usepackage{caption}  % If you need additional caption functionalities
\usepackage{hyperref} % Assuming you are using hyperref

\begin{document}

\begin{figure}[h]
  \centering
  \includegraphics[width=0.5\textwidth]{example-image} % Replace with your image
  \caption{This is the first line of the caption. \newline This is the second line.}
  \label{fig:example}
\end{figure}

\end{document}
In this example, `\newline` is used to insert a line break in the caption text, which should work without causing the `\Hy@tempa` error. If you encounter further issues, ensure that your LaTeX distribution and packages are up to date, as compatibility problems can sometimes be resolved with updates.

Output

The error you're encountering is related to the way LaTeX handles captions and line breaks within them. The `\\` command to force a newline may not always work as expected within the `\caption{}` environment, causing issues with certain packages like `hyperref` which uses `\Hy@tempa`. To properly handle line breaks within captions, you should use the `\newline` command or the `\linebreak` command instead of `\\`. Here's an example of how you can format your caption with line breaks: 

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
\documentclass{article}
\usepackage{caption}
\usepackage{hyperref}

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption{This is an example caption\newline with a forced line break.}
    \label{fig:example}
\end{figure}

\end{document}
Alternatively, if you want to use `\\` for line breaks, you can add the `\\` command within a `\protect` command to prevent the runaway argument issue: 
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
\documentclass{article}
\usepackage{caption}
\usepackage{hyperref}

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption{This is an example caption\protect\\ with a forced line break.}
    \label{fig:example}
\end{figure}

\end{document}
Using `\protect` before `\\` tells LaTeX to treat the `\\` command as a literal command and not to expand it prematurely, which can prevent the error you encountered. If you require more complex formatting within captions, consider using the `capt-of` package which provides more flexibility: 
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
\documentclass{article}
\usepackage{capt-of}
\usepackage{hyperref}

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \captionof{figure}[Short caption]{This is an example caption\protect\\ with a forced line break.}
    \label{fig:example}
\end{figure}

\end{document}
By following these approaches, you should be able to include line breaks in your captions without encountering the `\Hy@tempa` error.

Output

In LaTeX, using `\\` directly in a caption can indeed cause issues, as it might interfere with the internal workings of the `hyperref` package or other elements in the document. To properly handle newlines in captions, you should use the `\newline` command or the `\par` command instead of `\\`. Here's an example of how to do it correctly: 

 1

\begin{figure}[h]
\centering
\caption{This is the first line\newline
This is the second line}
\includegraphics[width=0.5\textwidth]{example-image}
\end{figure}

\end{document}
Alternatively, if you need more control over the formatting, you can use the `\captionsetup` command provided by the `caption` package to adjust the way captions are formatted. Remember to always use the `\caption` command within the context of a floating environment like `figure` or `table`. If you continue to have issues, ensure that your LaTeX distribution and packages are up to date, as sometimes bugs in older versions can cause unexpected behavior.

Output

When you encounter the error message `\Hy@tempa has an extra } runaway argument` in LaTeX while trying to force a newline in a caption using `\\`, it often indicates an issue with how the `hyperref` package is interpreting the caption. The `hyperref` package can sometimes struggle with special characters and commands within captions. To safely include a newline in a caption, you can use the `\newline` command instead of `\\`. Alternatively, you can use the `\protect` command to protect the newline command from being incorrectly interpreted by `hyperref`. Here’s how you can do it:

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image} % Use an example image
    \caption{This is a caption\protect\\with a newline.}
    \label{fig:example}
\end{figure}

\end{document}
Or using `\newline`: 
 1

    \caption{This is a caption\newline with a newline.}
    \label{fig:example}
\end{figure}

\end{document}
In these examples: - `\protect\\` ensures that the `\\` is protected and will not cause issues with `hyperref`. - `\newline` provides a similar result without causing issues. Choose the method that best fits your document’s needs.
