In latex when I force a newline in a caption with \\ it gives an error saying \Hy@tempa has an extra } runaway argument?
## The Error and its Cause The error message "runaway argument" in LaTeX usually indicates that there is an unmatched opening brace `{` somewhere in your code. In your case, the error occurs when you force a newline in a caption using `\\`. This is because the `\\` command is interpreted as an extra closing brace, leading to the "runaway argument" error. ## Possible Solutions Here are a few ways to fix this error: **1. Use `\newline` instead of `\\`:** The `\newline` command is specifically designed to insert a newline within a paragraph or caption. It does not introduce any additional braces and should work without causing the "runaway argument" error. **Example:**
1 2 3 4 | \begin{figure} \includegraphics{image.png} \caption{This is a figure caption with a newline.\newline Here is the second line.} \end{figure} |
1 2 3 4 | \begin{figure} \includegraphics{image.png} \caption{This is a figure caption with a literal backslash: \\.} \end{figure} |
1 2 3 4 5 6 7 | \usepackage{caption} \captionsetup{justification=centering,singlelinecheck=false} \begin{figure} \includegraphics{image.png} \caption{This is a figure caption with a newline.\newline Here is the second line.} \end{figure} |

When you force a newline in a caption with \\, you are essentially telling LaTeX to insert a newline character at that point. However, LaTeX also uses the \\ character to indicate the end of a line. So, when you use \\ in a caption, you are inadvertently telling LaTeX that the line has ended, even though it hasn't. This can cause LaTeX to throw an error, as it is expecting a closing brace for the caption. There are a few ways to fix this problem. One is to use the \\* command instead of \\. The \\* command is a special command that tells LaTeX to insert a newline character but does not end the line. This way, LaTeX will not throw an error. Another way to fix this problem is to use the \newline command. The \newline command inserts a newline character and also ends the line. However, this can cause the caption to be too long and wrap around to the next line. Finally, you can also use the \par command. The \par command ends the current paragraph and starts a new one. This can be useful if you want to force a newline in a caption and also want to start a new paragraph. Here is an example of how to use each of these commands:
1 2 3 4 5 6 7 8 9 10 11 | \begin{figure} \caption{This is a caption with a forced newline using \\*} \end{figure} \begin{figure} \caption{This is a caption with a forced newline using \newline} \end{figure} \begin{figure} \caption{This is a caption with a forced newline using \par} \end{figure} |

## Troubleshooting the `\Hy@tempa has an extra } runaway argument` error in LaTeX captions This error typically occurs when you have an unmatched closing brace `}` in your code, often within the caption or related to its formatting. Here are some steps to diagnose and fix the issue: **1. Check for unmatched braces:** * Carefully review your caption code, paying close attention to the placement of opening and closing braces. Look for any instances where a brace might be missing or misplaced. * If you're using nested commands or environments, ensure that the braces are properly balanced within each level. **2. Verify command usage:** * Double-check the syntax of any commands you're using within the caption, especially those related to formatting or line breaks. Ensure you're not accidentally introducing extra braces. * If you're using packages that modify captions, consult their documentation to ensure you're using the commands correctly. **3. Consider alternative line breaks:** * Instead of using `\\` to force a line break, explore other options like `\newline` or `\par`. These commands might be more appropriate depending on your desired formatting. * If you need to break a long line within a word, consider using the `\-\` command to hyphenate it. **4. Check for conflicting packages:** * Review the packages you're using in your document. Sometimes, conflicts between packages can lead to unexpected errors like this. Try temporarily disabling packages one by one to see if the error persists. **5. Consult online resources:** * Search online forums and communities like Stack Overflow for similar issues and solutions. Many users encounter this error, and there are often helpful discussions and solutions available. * Refer to the LaTeX documentation or relevant package documentation for specific guidance on the commands and syntax involved. **Additional Tips:** * Use a text editor with syntax highlighting to help identify potential errors in your code. * Consider using a LaTeX editor with built-in error checking and debugging tools. * If you're still struggling, provide a minimal working example of your code on a platform like Overleaf or pastebin, and seek help from the LaTeX community. By following these steps and carefully examining your code, you should be able to identify and fix the cause of the `\Hy@tempa has an extra } runaway argument` error in your LaTeX captions.
