GitHub copy code snippet

A userscript adds a copy to clipboard button on hover of markdown code snippets

• A button is added each pre formatted code block in markdown pages.
• Clicking the button will copy the contents of the code block to the clipboard.
• Buttons are not added to subdomains of GitHub, e.g. help.github.com, because the clipboard script is not loaded on those pages by default.
• Click this link to install from GitHub; or, install from GreasyFork or OpenUserJS.
