How do I link to an ID on a non org-mode file?

Question

I'd like to create a link inside an org-mode file to a source code file, say in C++. But I'd like the link to point to a possibly changing position in the file, so I want to use a unique identifier. For example, say the C++ file is as follows:

// {{{ 507ab9d0-d1a5-4fa9-97a9-d78a48a08c3d
<some content>
// }}}

I want to create a link that takes me to 507ab9d0-d1a5-4fa9-97a9-d78a48a08c3d. Can this be done in org-mode? I've been looking at org-id [1], but to the lay person, it does not seem to fit this use case.

Answer 1

You can use a file link like this:

file:f1.cpp::507ab9d0-d1a5-4fa9-97a9-d78a48a08c3d

It should open the file and then search for the string you put in.
