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 you're encountering is likely due to the fact that the `\\` command cannot be used directly in a caption to force a new line. Instead, you can use the `\newline` command or the `\\` command with the `\protect` command to force a new line in a caption. Here are two possible solutions: 1. Use the `\newline` command: 

1
\caption{First line of caption\newline Second line of caption}
2. Use the `\protect` command with the `\\` command: 
1
\caption{First line of caption\protect\\ Second line of caption}
Either of these solutions should allow you to force a new line in your caption without encountering the error message you described. If you're using a package such as `caption` or `subcaption`, you may have additional options for formatting your captions. Consult the documentation for those packages for more information.

Output

The error you're encountering is likely due to the fact that the `\\` command is not allowed in moving arguments, such as captions, section titles, and table of contents entries. In order to force a newline in a caption, you can use the `\newline` command or the `\\` command with the `[b]` option in the `caption` package. Here's an example:

  \captionsetup{format=hang,labelsep=newline}
  \caption{This is a long caption that needs to be split into two lines. Second line of the caption.}
\end{figure}

\end{document}
In the first example, we use `\newline` to force a newline in the caption. In the second example, we use `\\` with the `\protect` command to ensure that it works in moving arguments. In the third example, we use `\\` with a length option (`[1ex]`) to add some vertical space between the lines. In the fourth example, we use the `caption` package to change the formatting of the caption to hanging style with a newline separator. You can choose the one that works best for your particular use case.

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 you're encountering is likely due to the fact that the `\\` command is not allowed in moving arguments, such as captions, section titles, and other commands that may appear in the table of contents or in other parts of the document. To force a newline in a caption, you can use the `\newline` command or the `\\` command with the `[b]` optional argument to indicate that the line break should occur at a point where a line break is allowed in moving arguments. For example, you can use the following code to force a newline in a caption: 

1
\caption{First line of caption\newline Second line of caption}
or 
1
\caption{First line of caption\\[0.5ex] Second line of caption}
In the second example, the `[0.5ex]` optional argument adds some vertical space between the two lines of the caption. If you are still encountering the same error, it's possible that there is another issue in your code that is causing the problem. In that case, you may need to provide more information or a minimal working example (MWE) that reproduces the error so that others can help you diagnose and fix the issue.

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 you're encountering is likely due to the `\\` command being used in a context where it's not allowed, such as in a moving argument like a caption. The `\\` command is used to force a new line, but it's not suitable for use in captions because captions are designed to be single-line by default. To force a newline in a caption, you can use the `\newline` command or the `\protect\\` command. Here's an example: 

1
\caption{First line\newline Second line}
or 
1
\caption{First line\protect\\ Second line}
If you're still encountering the error message after trying these solutions, it's possible that there's another issue in your code that's causing the problem. In that case, you may want to post a minimal working example (MWE) that reproduces the error so that others can help you diagnose and fix the issue. Here's an example of a MWE that demonstrates the use of `\newline` in a caption:

begin{figure}
centering
Rule{5cm}{5cm}
caption{This is a long caption that needs to be split into two lines. Here is the first line, and here is the second line.}
end{figure}

end{document}
In this example, the `caption` package is used to ensure that the caption is formatted correctly. The `Rule{5cm}{5cm}` command is used to create a placeholder for the figure. The `\newline` command is used to force a newline in the caption.

Output

The error message you're seeing is likely due to the fact that the `\\` command is not allowed in captions by default in LaTeX. Captions are meant to be short, single-line descriptions, and forcing a new line can cause unexpected issues with the formatting and spacing of your document. However, if you really need to force a new line in a caption, you can use the `caption` package, which provides more flexibility in the formatting of captions. Here's how you can do it: 1. Include the `caption` package in the preamble of your document: 

1
\usepackage{caption}
2. Then, you can use the `\\` command to force a new line in your caption: 
1
2
3
4
5
\begin{figure}
\centering
\includegraphics{your_image}
\caption{First line of the caption \\ Second line of the caption}
\end{figure}
Remember to replace `your_image` with the actual path to your image file. If you're still encountering the error after using the `caption` package, it might be due to other issues in your document. In that case, you might want to check the rest of your code for any mistakes.
