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 usually occurs when there is a missing or extra brace (`{` or `}`) in your LaTeX code. When you use the `\\` command to force a newline in a caption, it should be placed inside the argument of the `\caption` command, like this: 

1
\caption{This is the first line of the caption\\This is the second line of the caption}
If you are still getting the error, it's possible that the problem is caused by other code before or after the `\caption` command. In that case, you can try adding `\protect` before the `\\` command, like this: 
1
\caption{This is the first line of the caption\\\protect\linebreak[0]This is the second line of the caption}
The `\protect` command tells LaTeX to treat the following command as if it were in the middle of a paragraph, which can prevent errors caused by missing or extra braces. Alternatively, you can use the `\par` command instead of `\\` to force a new line, like this: 
1
\caption{This is the first line of the caption\par This is the second line of the caption}
This will also give you a new line, but with some extra vertical space between the two lines. I hope this helps! Let me know if you have any other questions.

Output

The error message you're seeing is caused by a misuse of the `\\` command within a LaTeX caption. When you use `\\` to force a line break, LaTeX expects the next line to begin with a new command or text. However, it looks like you might be accidentally leaving an empty line or an extra curly brace `}` behind, which is causing the error. Here are a few things you can try to fix the error: 1. Check for extra white space: Make sure that there are no empty lines or spaces after the `\\` command. An easy way to check this is to comment out the `\\` command and see if the error goes away. If it does, then add the `\\` command back in and make sure there are no extra spaces after it. 2. Check for extra curly braces: Check for extra curly braces `{` or `}` in your caption. Make sure that every opening curly brace has a corresponding closing curly brace. 3. Use the `\caption*` command: If you just want to add a blank line or some vertical space in your caption, you can use the `\caption*` command followed by an empty set of curly braces `{}`. For example: 

1
2
3
\caption{This is my caption.}
\caption*{}\\
\caption{This is my second caption.}
This will create a blank line between the first and second captions. I hope that helps! Let me know if you have any further questions.

Output

This error typically occurs when the `\\` command is used outside of a tabular or array environment in LaTeX. In the case of a caption, you should not use `\\` to force a newline, but instead use the `\caption` command provided by the `caption` package with the `[newline]` option: 

1
2
3
4
5
6
7
\usepackage{caption}

\begin{figure}
\centering
\includegraphics{image.png}
\caption[Short caption]{This is a long caption that needs to be broken into multiple lines\newline Second line of the caption}
\end{figure}
Alternatively, you can use the `\par` command to insert a newline: 
1
2
3
4
5
\begin{figure}
\centering
\includegraphics{image.png}
\caption{This is a long caption that needs to be broken into multiple lines\par Second line of the caption}
\end{figure}
Note that using `\par` will also insert some vertical space between the two lines. If you don't want this space, you can use `\newline` instead: 
1
2
3
4
5
\begin{figure}
\centering
\includegraphics{image.png}
\caption{This is a long caption that needs to be broken into multiple lines\newline Second line of the caption}
\end{figure}

Output

The error message you're seeing is because the `\\` command is not supposed to be used to force a newline in a LaTeX caption. Instead, you should use the `\newline` command. Here's an example of how to use `\newline` in a caption: 

1
2
3
4
5
6
\begin{figure}
  \centering
  \includegraphics{your_image.png}
  \caption{This is the first line of the caption.\newline This is the second line of the caption.}
  \label{fig:my_figure}
\end{figure}
If you still want to use `\\` instead of `\newline`, you can use it inside the `\protect` command to prevent LaTeX from interpreting it as the end of an argument: 
1
2
3
4
5
6
\begin{figure}
  \centering
  \includegraphics{your_image.png}
  \caption{This is the first line of the caption.\protect\\ This is the second line of the caption.}
  \label{fig:my_figure}
\end{figure}
Note that the `\protect` command should only be used as a last resort, as it can interfere with other LaTeX commands. It's generally better to use LaTeX's built-in commands for formatting text whenever possible. I hope that helps! Let me know if you have any other questions.

Output

The `\\` command is not the correct way to force a newline in a LaTeX caption. Instead, you should use the `\newline` command or simply end the line and start a new one without any commands in between. For example, instead of writing: 

1
\caption{This is a long caption that needs to be broken into multiple lines \\ so that it fits within the width of the figure.}
You should write: 
1
\caption{This is a long caption that needs to be broken into multiple lines \newline so that it fits within the width of the figure.}
Or simply: 
1
2
\caption{This is a long caption that needs to be broken into multiple lines
so that it fits within the width of the figure.}
Note that there should be no space between the two lines in the second example. Regarding the error message you mentioned, it is likely caused by a missing or extra brace (`{}`) somewhere in your LaTeX code, which is causing LaTeX to become confused about the structure of your document. Double-check your braces and make sure they are all matched correctly. If you still can't find the error, try commenting out sections of your code to see if you can isolate the problem.
