# footnote-hell

Hello [^a].

[^a]: meow [^b]
[^b]: uwu [^a]

I expected to see this happen: all the links are correct, the backlinks are at least not completely wrong

Instead, this happened: a mess

Image

  • The first 1 points to #fn1
  • The second 1 points to #b
  • The third 1 points to #a

The backlinks are #fnref1 and #fnref2 respectively, which seems correct.

rustdoc: Clean up footnote handling

Best reviewed commit by commit.

Extracts footnote handling logic into it's own file (first commit) and then makes that file slightly nicer to read/understand.

No functional changes, but lays the groundwork for making more changes to footnotes (eg rust-lang#131901, rust-lang#131946)

That was a funny case. So the fix is simple: we need to check for footnote references in footnote definitions. I have a fix ready, sending the patch once I added tests.

Fixes rust-lang#131946.

We didn't check if we had footnote reference in footnote definition.
