First PR, please let me know if I'm doing anything wrong.

As noted in #98769, currently cargo doc --open on macOS/Safari (17.2.1) doesn't load fonts due to a CORS issue. (webkit issue here). This patch moves the font preloads inside a js if statement as suggested in the GitHub issue.

I tried something more elegant with iterating over a tera array of fonts, but ran into issues, so here's the dumb fix. Only thing to note is that the font path is interpolated into a template string, so HTML escaping works fine, but it will break if there's a backtick or ${ in the font path. Not sure if this is a big deal.

No complaints, other than keeping the issue open because this is, unfortunately, an incomplete solution. It doesn't help unless the Develop menu is turned on.

Oh, I didn't even notice - I thought that referred to the developer console being open. Do you have a more general workaround in mind? I can figure it out otherwise

rustdoc: do not preload fonts when browsing locally

First PR, please let me know if I'm doing anything wrong.

As noted in rust-lang#98769, currently `cargo doc --open` on macOS/Safari (17.2.1) doesn't load fonts due to a CORS issue. (webkit issue [here](https://bugs.webkit.org/show_bug.cgi?id=249887)). This patch moves the font preloads inside a js if statement as suggested in the GitHub issue.

I tried something more elegant with iterating over a tera array of fonts, but ran into issues, so here's the dumb fix.

Do you have a more general workaround in mind?

I was thinking of integrating a small HTTP server into Rustdoc1. That would definitely solve this problem, along with a few other problems like localStorage partitioning.

This solution is controversial, which is why I didn't block this PR it.

Footnotes

  1. If it's in Rustdoc, then Rustup and Cargo can both use it.
