Adding Copy Buttons to Your Sphinx Documentation#
Introduction to the Copy Button#
Have you ever wished you could easily copy code blocks directly from your Sphinx-generated documentation? The sphinx-copybutton extension makes this a reality. By adding a small button to each code block, you can effortlessly copy the code to your clipboard.
This is a fantastic way to enhance user experience and make your documentation more user-friendly as it allows readers to quickly copy code snippets for testing or reference. In this article, we’ll show you how to add copy buttons to your Sphinx documentation using the sphinx-copybutton extension.
Improved User Experience: Makes it easier for users to interact with your documentation and experiment with the code.
Increased Efficiency: Saves time for users by eliminating the need to manually copy and paste code.
Enhanced Accessibility: Makes your documentation more accessible to users with disabilities who may have difficulty copying code.
Installation of the extension#
First install the extension using pip:
pip install sphinx-copybutton
Enable the extension by adding the following line to your conf.py file:
extensions = [
# ... other extensions
"sphinx_copybutton",
]
Don’t forget to rebuild your documentation after making these changes and to see the copy buttons in action. But also to add the dependencies to your requirements.txt file:
sphinx-copybutton==0.5.3
Or to the pyproject.toml file:
[build-system]
requires = ["sphinx-copybutton==0.5.3"]
Optional Configuration#
You can customize the appearance and behavior of the copy buttons using the following configuration options in your conf.py file:
copybutton_prompt_text = r">>> |\.\.\. " # Customize the prompt text
copybutton_prompt_is_regexp = True # Treat the prompt as a regular expression
copybutton_only_copy_code_blocks = False # Copy all code blocks, not just those with prompts
copybutton_remove_prompts = True # Remove prompts from copied code
copybutton_trim_trailing_whitespace = True # Trim trailing whitespace from code blocks
These options allow you to tailor the behavior of the copy buttons to suit your specific needs and preferences, and a full list of available configuration options can be found in the sphinx-copybutton documentation.
Styling the Copy Button#
You can customize the appearance of the copy button using CSS. Here’s an example of how you can style the button:
.copybutton {
background-color: #f0f0f0;
color: #333;
border: 1px solid #ccc;
border-radius: 3px;
padding: 2px 5px;
font-size: 0.8em;
cursor: pointer;
}
.copybutton:hover {
background-color: #e0e0e0;
}
.copybutton::after {
content: "Copy";
}
.copybutton.copied::after {
content: "Copied!";
}
You can add this CSS to your Sphinx theme or use a custom CSS file to apply the styles to the copy buttons.
