In latex when I force a newline in a caption with \\ it gives an error saying \Hy@tempa has an extra } runaway argument?

Output

The error message "\Hy@tempa has an extra } runaway argument" usually occurs when there is a mismatch in the number of curly braces or an issue with the arguments passed to a command. In the case of using `\\` to force a newline in a caption, it's possible that the caption package or the hyperref package (if used) is conflicting with the line break command. To resolve this issue, you can try the following alternatives to force a newline in the caption: 1. Use `\newline` instead of `\\`: 

1
2
   \caption{First line\newline Second line}
2. Use `\protect\`: 
1
2
   \caption{First line\protect\\Second line}
The `\protect` command instructs LaTeX to handle the following command (in this case, `\\`) correctly. 3. Use the `caption` package and its `\caption*` command: 
1
2
3
4
   \usepackage{caption}
   ...
   \caption*{First line\\Second line}
The `\caption*` command is provided by the `caption` package and allows line breaks using `\\` without the need for `\protect`. 4. Use a parbox or minipage environment: 
1
2
   \caption{\parbox{\linewidth}{First line\\Second line}}
or 
1
2
   \caption{\begin{minipage}{\linewidth}First line\\Second line\end{minipage}}
This approach wraps the caption text within a box, allowing line breaks with `\\`. Try one of these alternative methods to force a newline in your caption, and it should resolve the "\Hy@tempa has an extra } runaway argument" error.

Output

The error message "Runaway argument" usually indicates a mismatched pair of curly braces or a missing closing brace. In this case, the issue is likely caused by using `\\` directly in the caption. To force a newline in a caption without causing an error, you can use the `\protect` command before the line break. Here's how you can modify your code: 

1
\caption{First line of the caption\protect\\Second line of the caption}
The `\protect` command tells LaTeX to treat the following command (in this case, `\\`) as a normal command, even if it appears in a moving argument like a caption. Alternatively, you can use the `caption` package, which provides a more robust way to handle line breaks in captions. First, make sure you have the package included in your preamble: 
1
\usepackage{caption}
Then, you can use the `\\` command without the need for `\protect`: 
1
\caption{First line of the caption\\Second line of the caption}
The `caption` package takes care of the necessary protection for you. Either of these methods should resolve the "Runaway argument" error and allow you to force a newline in your caption.

Output

The error message "\Hy@tempa has an extra } runaway argument" typically occurs when there is a mismatch in the number of curly braces ({}) within a command or environment. When you use \\ to force a newline in a caption, it's possible that it interferes with the internal workings of the caption command, leading to the error. To resolve this issue, you can try the following alternative methods to add a newline in your caption: 1. Use the `\newline` command instead of `\\`: 

1
\caption{First line of the caption \newline Second line of the caption}
2. Use the `\par` command: 
1
\caption{First line of the caption \par Second line of the caption}
3. Use a separate `\caption` command for each line: 
1
2
\caption{First line of the caption}
\caption*{Second line of the caption}
Note: The `\caption*` command is used for the second and subsequent lines to prevent incrementing the caption counter. 4. If you are using the `subcaption` package, you can use the `\protect\\` command: 
1
\caption{First line of the caption \protect\\ Second line of the caption}
Try one of these alternative methods instead of using `\\` directly in the caption. It should resolve the "\Hy@tempa has an extra } runaway argument" error.

Output

The error message "\Hy@tempa has an extra } runaway argument" typically occurs when there is a mismatch in the braces `{}` within your LaTeX code. When using `\\` to force a newline in a caption, you need to be careful with the syntax. Here are a few things to check: 1. Make sure you are using the correct syntax for the caption command. It should be `\caption{}` with the caption text inside the braces. 2. If you want to include additional options or formatting within the caption, you should use square brackets `[]` before the caption text. For example: `\caption[Short caption for list of figures]{Long caption with \\ newline}`. 3. If you have any other commands or formatting within the caption text, ensure that they are properly enclosed within braces `{}` to avoid conflicts. Here's an example of a correct usage of `\\` in a caption: 

1
2
3
4
5
\begin{figure}
    % Your figure content here
    \caption[Short caption]{Long caption with\\newline}
    \label{fig:example}
\end{figure}
In this example, the short caption (used in the list of figures) is provided in square brackets `[]`, while the long caption (displayed below the figure) is provided in braces `{}`. The `\\` is used within the long caption to force a newline. If you still encounter the error after following these guidelines, please provide the specific code snippet where the error occurs, and I'll be happy to help you further.

Output

The error message "\Hy@tempa has an extra } runaway argument" typically occurs when there is a mismatch in the number of braces or improper usage of commands within the caption. To force a newline in a caption, instead of using `\\`, you should use the `\protect\newline` command. The `\protect` is necessary to ensure that the `\newline` command is properly handled within the caption. Here's an example of how to use `\protect\newline` in a caption:

\begin{figure}
  \centering
  \includegraphics[width=0.8\textwidth]{example-image}
  \caption{This is the first line of the caption.\protect\newline
           This is the second line of the caption.}
  \label{fig:example}
\end{figure}

\end{document}
In this example, the caption will have a line break between "This is the first line of the caption." and "This is the second line of the caption." Alternatively, you can use the `caption` package, which provides more flexibility in formatting captions. With the `caption` package, you can use `\\` directly without the need for `\protect`:

  \caption{This is the first line of the caption.\\
           This is the second line of the caption.}
  \label{fig:example}
\end{figure}

\end{document}
Using the `caption` package allows you to use `\\` directly within the caption to force a line break. Remember to compile your LaTeX document twice to ensure that the references and hyperlinks are properly updated.
