Link to source file location with content preview

[Daniele Nicolodi]

Hello,

I would like to create links from an org-mode file to source file
locations that display a preview of the link destination in the form of
a source code block or similar with a few lines of the file content.

Is this doable with org-store-link and org-insert-link?

A related question: does anyone have some elisp code that turns a Grep
buffer (the results of running "M-x grep") into org-mode links to the
locations?

Thank you!

Cheers,
Dan
