Link Anything

[dylanowen]

Problem

It is very useful with spec-md to be able to share a link to anything:
https://spec-md.com/#sel-EAHHFCAACCyFm2Q

It would be great if we could include this functionality in mdBook.

Proposed Solution

https://github.com/leebyron/spec-md/blob/main/src/client/linkSelections.js is the implementation for md-spec

https://github.com/WesleyAC/deeplinks is another implementation

Notes

I managed to get deeplinks.js working with the existing html renderer configuration options however it was a bit clunky:

additional-js doesn't work as deeplinks.js is a module and additional-js doesn't account for that. additonal-js also doesn't copy over dependency imports. Maybe we could define a folder inside of theme that was copied over completely?

I was able to get this working by including a folder in my src directory as js which is copied over to the final book (any name works really). I then changed my theme/head.hbs to:

<script type="module" src="{{path_to_root}}/js/deeplinks.js"></script>

and included this additional-css:

* {
    /* Make sure when we scroll we don't hide our target under the menubar */
    scroll-margin-block-start: calc(var(--menu-bar-height) + 2em);
}
