Use sphinx-hoverxref in traceability links

[David-Le-Nir]

I'd like to use sphinx-hoverxref on traceability links of my needs.

For example, if I have something like

.. req:: my req
   :link: other-external-req

I'd like to have the hoverxrek applying on the link (i.e. when I hover the other-external-req in html see the tooltip with the content). The main issue is that we cannot use a role in a directive option.

I tried multiple approaches, obviously not working, such as

with role on link option

.. req:: my req
   :link: :hoverxref:`other-external-req`

with role on an option not transformed to html link

.. req:: my req
   :link: other-external-req
   :a_non_link_field: :hoverxref:`other-external-req <url ...>`

with a dynamic function returning the string :hoverxref:other-external-req <url ...> or the raw html

.. req:: my req
   :link: other-external-req
   :a_non_link_field: [[a_dynamic_function('other-external-req')]]

with the raw html

.. req:: my req
   :link: other-external-req
   :a_non_link_field: <a class="hxr-hoverxref hxr-modal reference external" href="http://...">other-external-req</a>

Do you think it is achievable ? If so, what would you try ?

The extension is working well in the need content but this is not what I want ^^

thanks in advance

It is currently not possible to write rst syntax in needs options or links.
To make it possible is a lot of effort.

But you could try the extension sphinx-preview.

Thanks a lot, it seems exactly what I want to achieve
