Additional additions

As requested, I've added "copy" buttons to easily copy the specific URL.

On top of that, I've taken the liberty to add a "Successfully copied to clipboard." notification to the top of the page. This change can be easily reverted if necessary.

Notification showcase

Note: The copy notification banner is implemented by directly manipulating the flash message DOM element, rather than using Rails server-side flash_message helper, because it is handled entirely client-side with navigator.clipboard (does not involve a server request or page reload).

Final notes

1. No tests were added since there are no existing view or system tests for this page. Furthermore, the copy button relies on navigator.clipboard, which would require Capybara (seems to be included in the gemfile) to test. This would be outside the scope of this task.

Would love to get feedback on this ^^ :0

2. The flash message string is defined as an i18n key in config/locales/views/groups/en.yml under student_interface, since that's where the other keys used by the repository URL section are located.

Hi @Karl-Michaud, yes you can add a "Copy" button. Take a look at what we're doing to support text file copying in the TextViewer component. I'm also good if you want to add the "copy" icon from FontAwesome.

Hi @david-yz-liu,

Here is an updated screenshot of the page after changes. Notably, switching from <span> tags to <code> tags which changed the font of URL text.
