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" typically occurs when there is a mismatch in the number of curly braces or an issue with the syntax within the caption. To force a newline in a caption, instead of using `\\`, you should use `\protect\newline`. The `\protect` command is necessary to ensure that the `\newline` command is properly processed within the caption. Here's an example of how you can use `\protect\newline` in a caption: 

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

\begin{document}

\begin{figure}
  \centering
  \includegraphics[width=0.5\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 the first and second lines. Remember to use `\protect\newline` instead of `\\` whenever you want to force a newline within a caption or other similar environments in LaTeX.

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

Output

This error typically occurs when you have an unescaped underscore character (`_`) in your caption text. In LaTeX, the underscore is a special character used for subscripts, so it needs to be escaped when used in regular text. To fix this issue, you can try the following: 1. If you have any underscores in your caption text, escape them by adding a backslash before the underscore, like this: `\_`. For example, if your caption contains "file_name", change it to "file\_name". 2. If you don't have any underscores in your caption, make sure that you have properly closed all curly braces `{}` and that there are no other syntax errors in your caption or the surrounding code. Here's an example of a corrected caption with a forced newline: 

1
2
\caption{This is the first line of the caption.\\
This is the second line of the caption after the forced newline.}
If the issue persists, you can try using the `caption` package, which provides more flexible caption formatting options. To use it, add the following line to your preamble: 
1
\usepackage{caption}
Then, you can use the `\caption` command with the `\newline` command to create a line break in your caption: 
1
2
\caption{This is the first line of the caption.\newline
This is the second line of the caption after the forced newline.}
If the error still occurs, please provide more details about your specific use case, and I'll be happy to help you further.

Output

The error message "\Hy@tempa has an extra } runaway argument" usually occurs when there is a mismatch in the number of curly braces ({}) within the caption. 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 have properly closed all curly braces within the caption. 2. If you are using any LaTeX commands or macros within the caption that require arguments, ensure that the arguments are properly enclosed in curly braces. 3. Instead of using \\ directly, you can try using the \newline command or the \par command to force a newline in the caption. Here's an example of how you can use \newline or \par in a caption: 

1
2
\caption{This is the first line of the caption.\newline
This is the second line of the caption.}
or 
1
2
\caption{This is the first line of the caption.\par
This is the second line of the caption.}
If you still encounter the error after trying these suggestions, please provide the specific code snippet where you are using the caption, and I'll be happy to take a closer look and provide further assistance.

Output

The error message "\Hy@tempa has an extra } runaway argument" usually occurs when there is a mismatch in the braces or an incorrect usage of certain commands within the caption. In LaTeX, forcing a newline with `\\ ` inside a caption can be problematic because the caption is already a sensitive environment. Instead of using `\\ `, you can try the following alternatives: 1. Use the `\newline` command: 

1
2
   \caption{First line \newline Second line}
2. Use the `\par` command: 
1
2
   \caption{First line \par Second line}
3. Use the `caption` package and its `\caption*` command: 
1
2
3
4
   \usepackage{caption}
   ...
   \caption[Short caption]{First line \\ Second line}
In this case, the optional argument `[Short caption]` is used for the list of figures or tables, while the actual caption can contain the newline command. 4. Use a tabular environment inside the caption: 
1
2
3
4
5
6
7
   \caption{
     \begin{tabular}{@{}l@{}}
       First line \\
       Second line
     \end{tabular}
   }
Try one of these alternative methods to add a newline within your caption without encountering the "\Hy@tempa has an extra } runaway argument" error.

Output

The error message "\Hy@tempa has an extra } runaway argument" usually occurs when there is a mismatched or extra curly brace (`}`) in your LaTeX code, often related to the hyperref package. In the context of forcing a newline in a caption using `\\`, the error might be caused by a conflict between the hyperref package and the caption formatting. To resolve this issue, you can try the following: 1. Instead of using `\\` to force a newline, use the `\newline` command: 

1
\caption{First line of the caption\newline Second line of the caption}
2. If you want to stick with `\\`, you can use the optional argument of the `\caption` command to create a short caption for the list of figures/tables and a long caption for the actual figure/table: 
1
\caption[Short caption]{First line of the long caption\\ Second line of the long caption}
3. Another option is to use the `caption` package, which provides more flexibility in formatting captions. You can use the `\protect` command before `\\` to prevent the hyperref package from interfering with the caption formatting: 
1
2
3
\usepackage{caption}
...
\caption{First line of the caption\protect\\ Second line of the caption}
Try one of these solutions and see if it resolves the error. If the issue persists, please provide more details about your LaTeX code and the packages you are using, so I can better assist you.
