Local fallback for CDN hosted ressources

[azerupi]

• Font Awesome
• Google Fonts (Open Sans) Edit: maybe not that important, other (similar) fonts will be used instead
• JQuery
• MathJax

Are loaded from CDN's but should have a local fallback for offline use and for when the CDN is down.

[azerupi]

MathJax seems like a lot of files, currently not easily embeddable into the binary (as far as I know)..

JQuery and Font Awesome where the most important ones. I will therefore remove this issue from 0.0.2 milestone. Leave it like this until a better solution is found.

FYI: MathJax CDN is shutting down. Might want to switch to CDNJS in the meantime.

It would be good to add an option to disable remote loading completely. We have all of this stuff in Debian and would ideally just point to the local files. At the moment we have to carry patches in rustc instead.

One primary benefit of loading this stuff locally, is that my ISP really doesn't need to know when I'm reading rust documentation. :/

[azerupi]

@infinity0 You mean when you are reading the docs locally?
Indeed the CDN thing is only an improvement when loading from a remote source. I am not sure how I could differentiate the two use cases though?

[infinity0]

Perhaps it could read a mdbook.toml file that lets you define alternate local URLs for these resources? Or, get them from an environment variable.

[azerupi]

Do you want to deactivate the CDN completely everywhere?

[infinity0]

Yeah, that would be nice. We have them available locally in various subdirectories of /usr/share/fonts and /usr/share/javascript, though I can't speak for other distros.

I have made a new issue #271. Feel free to comment there :)
