Hello -- I'm wondering about my question from here:
https://emacs.stackexchange.com/questions/77768/why-the-inconsistency-with-org-mode-code-line-labels-and-links
Copying my question: in a source code special block, I can add code line
labels, which have ref: in the label -- but when I make a link there, I
have to omit the ref:. For example:
#+begin_src csharp
1044 string foo = someFunction(1234);
1045 if (foo == "1")
1046 {
1047 bar = 5; // (ref:my-code-line-label)
1048 }
// etc etc
#+end_src
There's a bug [[(my-code-line-label)][right here]].
This seems inconsistent. Why do I have to omit the ref: bit? This always
confuses me; it seems like it would be simpler to just make the label and
the links to that line of code be exactly the same. I don't see any
particular reference to this in the org manual (
https://orgmode.org/manual/Internal-Links.html). Any insights?
My idea would be to get rid of the special behavior for code line labels
and just make this work with dedicated targets: in regular parts of my org
file, I use <<link-target>> and can make links to that. It would be simple
and consistent to make that also work the same when <<link-target>> is
inside a code block.
Thanks!

Such link targets would conflict with <<code-block-id>> references
See: https://orgmode.org/manual/Noweb-Reference-Syntax.html
Therefore something like the behavior described in
https://orgmode.org/manual/Literal-Examples.html
must have been invented (look at the description of the -n, -r, and
-l switches).

The way coderefs appear in the code are completely configurable using
org-coderef-label-format ("(ref:%s)" by default) and using -l src code
switch.

If you examine 12.6 Literal Examples section of Org manual, you will see
that coderef links are exported specially:
In literal examples, Org interprets strings like ‘(ref:name)’ as
labels, and use them as targets for special hyperlinks like
‘[[(name)]]’—i.e., the reference name enclosed in single parenthesis.
In HTML, hovering the mouse over such a link remote-highlights the
corresponding code line, which is kind of cool.

I should have mentioned that I'm not exporting any of this. I only use org
by itself; I never export things to other formats. So the link behavior
that I need is for making and following links inside org/emacs; noweb and
other things aren't important.
The (ahem) link to the org-coderef-label-format is what I was looking for:
I set that to just (%s) and now something like the above example works
without adding the "ref:" bit. I'll update the emacs.sx post.
Thanks!
