Broken URLs since Hugo 101 due to leading slash and relURL

[Marzal]

Since Hugo 101, if you use a leading slash in a path with relURL, Hugo will not prepend the baseURL directory as documented in this issue gohugoio/hugo#10049

For context, see:

• Commit Fix relURL with leading slash when baseURL includes a subdirectory gohugoio/hugo#10002
• Bug Bug in relURL with leading slash when baseURL includes a subdirectory gohugoio/hugo#9994

I only have seen problems in 101 with

• https://github.com/google/docsy/blob/main/layouts/partials/scripts.html#L27
• https://github.com/google/docsy/blob/main/layouts/partials/scripts.html#L31

But I suppose that at least these could have the same problem
https://github.com/google/docsy/blob/main/layouts/partials/scripts.html#L74
https://github.com/google/docsy/blob/main/layouts/partials/head.html#L41
https://github.com/google/docsy/blob/main/layouts/partials/community_links.html#L17
https://github.com/google/docsy/blob/main/layouts/404.html#L5
https://github.com/google/docsy/blob/main/layouts/swagger/baseof.html#L6
https://github.com/google/docsy/blob/main/layouts/swagger/baseof.html#L25
https://github.com/google/docsy/blob/main/layouts/swagger/baseof.html#L26

Tasks:

• Hugo relURL fix for CSS and JS paths #1127
• 404 layout: fix relURL argument #1134

Thanks for spotting that, does it look like this is a permanent breaking change in Hugo that we'll need to work around/update or something that's likely to go away in a future version?

As far as I understand from the conversation in the links above, the old behavior (Hugo <101) was an unwanted behavior now fixed.

Here is a good summary of how things are now implemented:

Thanks for the detailed report @Marzal! I'm investigating.

From the tests that I've run, surprisingly "/" seems to still work, but that seems odd. Thanks for the reference, I'll give "" a try.

I don't believe that there are any further changes necessary to address this issue. So I consider it closed by #1134.
