dirhtml build index.html does not redirect to root folder

[jackminchin]

Describe the problem

When running the dirhtml build option, the root index.html doesn't change to point to the /{rootName}/index.html, instead it just points directly to /{rootName}.html.

thanks for reporting this @jackminchin I can replicate this issue locally.

Looks like the index.html is written assuming the html

<meta http-equiv="Refresh" content="0; url=intro.html" />

and it should be

<meta http-equiv="Refresh" content="0; url=intro/index.html" />

Do you get the following message in your build output

@chrisjsewell is this index.html written by https://github.com/executablebooks/sphinx-external-toc given the [etoc] message indicator?

[etoc] missing index.html written as redirect to 'intro.html'

This still seems to be an issue.

[etoc] missing index.html written as redirect to 'intro.html'

However the intro.html file is in a "intro/index.html" folder

👋🏼 everyone, I was facing this issue while working on https://jdsalaro.com and https://fhirpack.readthedocs.io so I decided to investigate a bit. In https://github.com/executablebooks/sphinx-external-toc/issues/93 I suggest a fix, but it will probably take a bit until that small fix reaches everyone getting sphinx-external-toc via PyPI.

There are three possible solutions:

1. create your book as usual, keep the intro.md root and always modify your generated _build/dirhtml/index.html to contain <meta http-equiv="Refresh" content="0; url=intro/index.html" /> or the respective root_doc you have chosen <meta http-equiv="Refresh" content="0; url=root_doc/index.html" />

2. is likely the simplest, just stop using intro.md as a root document by modifying your _toc.yml file and renaming it to index, then this issue will not arise.

3. patch events.py in sphinx-external-toc according to https://github.com/executablebooks/jupyter-book/issues/1414 or wait and use sphinx-external-toc once it's released.
