Add relative path to current page to (icon) links in header?

[jpfeuffer]

Hi!

Is it possible to add/append a relative path to the current page to (icon) links in the header?
We are evaluating this theme but we need a "Run on Binder" button for each page that links to the same file/its ipynb version
on the Binder instance.
Similar to the Sphinx-Book-Theme which unfortunately has other issues like no version selector and header.
I assume this functionality would be very similar to the "Edit this page" link which exists already in the right sidebar. Having for example a shield badge/button there would also be fine.

Thanks!

I figured it out:

_templates/navbar-run-binder.html

<div class="navbar-end-item">
  <ul id="navbar-icon-links" class="navbar-nav" aria-label="Icon Links">
  <li class="nav-item">
    <a href="https://mybinder.org/v2/gh/{{ github_user }}/{{ github_repo }}/{{ github_version }}+ipynb?urlpath=lab/tree/{{ doc_path }}{{ pagename }}.ipynb" title="" class="nav-link" rel="noopener" target="_blank" data-toggle="tooltip" data-original-title="Launch on Binder"><span><i class="fa fa-rocket"></i></span>
      <label class="sr-only">Launch on Binder</label></a>
  </li>
</ul>
</div>

conf.py

html_theme_options = {
    "navbar_end": ["navbar-run-binder", "navbar-icon-links"],
}
