This adds dynamic navigation of headers of the current page in the
sidebar. This is intended to help the user see what is on the current
page, and to be able to more easily navigate it. The "current" header is
tracked based on the scrolling behavior of the user, and is marked with
a small circle. This includes automatic folding to help keep it from
being too unwieldy on a page with a lot of nested headers.
This includes the `output.html.sidebar-header-nav` option to disable it.
I'm sure there are tweaks, fixes, and improvements that can be made. I'd
like to get this out now, and iterate on it over time to make
improvements.
This updates eslint to lint on the toc.js.hbs file. This file uses a
small amount of hbs templating which eslint can't handle. This adds a
hacky preprocessor which will strips out the handlebars tags so that the
file can be linted.
This requires a switch to the configuration file format described at
https://eslint.org/docs/latest/use/configure/configuration-files. I used
the automatic tool to generate the new file, with some simplifications
around defaults.
- Removed no-cond-assign override, it is no longer needed.
- Fixed `catch (e)` where `e` is not used. This seems a little pedantic
to me, but seems like a relatively easy fix to just remove it, and I
believe the syntax without the variable has been supported for quite
some time. Alternatively it could also be `_e`, or explicitly allowed.
- Added `--no-warn-ignored` to the script since it was very noisy.
This is a pure git rename in order to make sure that git can follow
history. The next commit will integrate these into mdbook-html.
Additional commits will refactor/move/remove items.
