In case 'just-the-docs' is used as a theme, and a user does not
eplicitly include 'jekyll-seo-tag' inside the plugins list in
_config.yml, two 'title' elements were rendered. Since
jekyll-seo-tag is always available, because it's set in the plugins
list of the theme itself, the 'seo' tag will aways work, making
the seperate title and description elements obsolete.

- Move the display of nav external links from `_includes/nav.html` to `_layouts/default.html`.
- Replace ` unless include.key` by `if site.nav_external_links`.
- Wrap the body of `if site.nav_external_links` in `<ul class="nav-list">…</ul>`.
To test this PR:
1. Add to `_config.yml`:
```yaml
defaults:
-
scope: {path: ""}
values: {nav_exclude: true}
```
2. Check that the only link to appear in the nav panel is external.

Fixes#1014
1. Reverse the order of `page.parent == node.title or page.grand_parent == node.title`. This makes no difference.
2. Replace `page.parent == node.title` by `page.parent == node.title and page.grand_parent == nil`. The condition is evaluated first because it is rightmost.
We have `node in first_level_pages`.
The old condition holds not only when `page` is a child of `node`,
but also when `page` is a grandchild of a *different* top-level page and its parent happens to have the same title as `node`.
The new condition never holds for a grandchild.
This change has been tested locally: in v0.4.0.rc3, when the 3rd-level page `G` was selected, the link to the top-level page `F` was active, and the link to its child `G` was shown; after making the change, it is no longer active, so the link to its child `G` is not shown.
* Update nav.html
Add a comment to clarify just when top-level nodes are active.
The regression tests in https://just-the-docs.github.io/just-the-docs-tests/navigation/grandparent/index/ include a section "A grandchild with the same parent title as a child or top-level page". Its last item fails, as can currently be seen at https://just-the-docs.github.io/just-the-docs-tests/navigation/grandparent/f/ : the first occurrence of `G` links to the grandchild of `E`., and shouldn't be included.
The regression can be fixed by changing `where: "grand_parent", page.parent` to `where_exp: "item", "item.grand_parent == page.parent"`. This should be apparent when running the regressions tests with this PR branch as remote theme.
The two filters give the same results in Jekyll 4, but not in Jekyll 3. It seems that this was overlooked because the sanity-testing of v0.4.0.rc3 was inadvertently using Jekyll 4.2.2.
Fix external links and collections
The navigation should only display the external links once, after the links to pages that are not in collections.
The test for PR #876 at https://just-the-docs.github.io/just-the-docs-tests/navigation/external-links fails with v0.4.0.rc3,
and succeeds when the updated `nav.html` is added locally.
The docs need updating to clarify how the interaction between the collections feature and the external links feature is resolved.
* Optimize simple navigation cases
Fix inefficiency reported in feedback on v0.4.0.rc2 (see discussion #958).
This PR:
* essentially reverts `_includes/nav.html` to v0.4.0.rc1
* preserves the ARIA labels added by #950
* adds a test to optimize builds of sites that rely on `title` fields to order pages.
Building the `endoflife.date` site (130 pages) now takes only about 7 seconds.
Building the `machinetranslate.org` site ( 350 pages) takes about 7 minutes. (Without the added test, it takes just over 5 minutes: the condition of the test is merely to compare the size of two arrays, but that is apparently enough to prevent Jekyll from applying some optimization).
A warning is added to the docs about the need for numbers to be in quotes when used as title values.
* Update navigation-structure.md
A clarification is added to the docs about the need for numbers to be in quotes when used as title values.
* Simplify the control and data flow
- Defer concatenation of `string_order_pages` with `title_order_pages` until needed.
- Replace tests on size with tests for `empty`.
- Rename variables accordingly.
* Fix child nav order
This PR started from the navigation in RC1. Some cosmetic improvements had been made in RC2. This commit adds some of those changes to this PR.
It also fixes a bug (revealed by a new regression test) due to a reference to `node.child_nav_order` instead of `child.child_nav_order`, which prevented reversal of the order in children of children. Presumably a top-level reversal should apply only to direct children, and not to grandchildren. The latter interpretation would be very confusing in a deep multi-level hierarchy.
* Allow pages with numeric titles
An omitted `nav_order` value should default to the `title` value, regardless of its type. Jekyll 3 gives build errors when numbers and strings are sorted together. This commit drops the assumption that `title` values are always strings – a 404 page naturally has a numeric title. It updates the docs page accordingly.
The extra code does not affect the build time for the `endoflife.date` site (7 seconds). For the `machinetranslate` site, changing the title of the 404 page to a number increases the build time from 7 minutes to 9 minutes – the `nav_order` numbers on that site are program-generated in the range 1..1000, which might be atypical.
This commit has not yet been checked using the regression tests.
The gemspec used for testing specifies `spec.add_runtime_dependency "jekyll", "~> 3.8.5"`, and `Gemfile.lock` shows `jekyll (3.8.7)`.

Minor improvements and cosmetic changes.
* Major revision
This update is based on extensive experimentation and profiling with alternative versions of the Liquid code used to build the main navigation panel.
Due to the fragility of Jekyll's optimizations, combining alternative approaches with conditionals turned out to be too expensive: merely adding a condition to check whether some array of pages is empty can add about 20% to the build time!
The current code avoids sorting pages on `nav_order` and `title` fields together. The standard way of doing that in Jekyll is to use the `group_by` filter; but extracting the sorted pages from the groups turned out to be too inefficient (as seen in RC1), as was generating links directly from the groups (in RC2).
Making all pages with `nav_order` values come before all those ordered by their `title` values is not ideal (it doesn't support tweaking the relative order of two pages in a list of pages ordered by their titles) but it appears to be necessary for efficient builds on large sites.
This version has not yet been fully tested for regression, but otherwise seems to give the expected navigation on the endoflife.date and machinetranslate websites. (I'm unable to install the Python-based how2data repository on my laptop, due to package version issues on Apple silicon).

* Fix default highlighting in custom schemes
Fix#982
The variable settings for highlighting in the default `light` scheme are currently (v0.4.0.rc2`) in `_sass/color_schemes/light.scss`.
This PR ensures that custom schemes are based on the `light` scheme.
It also adds a note explaining the default to the customization docs,
and gives an example of how to define a custom scheme based on the `dark` scheme

* Add toc heading custom include
Closes#961.
* Revert "Add toc heading custom include"
This reverts commit 49813c341973e313db0a21f075a60ebf2120989e.
* Update code highlighting with line numbers
- Add the example of code highlighting with line numbers explained in the [Jekyll docs](https://jekyllrb.com/docs/liquid/tags/#line-numbers).
- Fix the styling of narrow code with line numbers, which floats to the centre without this CSS adjustment. (The line numbers column expands as needed with larger numbers of lines, despite using `width`; using `min-width` doesn't work.)
To apply HTML compression, I removed `vendor` from `exclude`; that change is left to a different PR.
* Make more CHANGELOG urls clickable
Extension of PR #977 to v0.4.0.rc1:
- Make callouts `loud`.
- Replace a warning paragraph by a callout.
- Use a reference link instead of an explicit url for @pmarsceill .
- Add link reference definitions for PRs and new contributors in v0.4.0.rc1.
- Replace inline urls by shortcut link references.
The changes to replace URLs by link references would be too tedious and error-prone to do completely manually for v0.4.0.rc1.
The following regexp replacements were applied to the sections of v0.4.0.rc1, using Atom:
- Copy a section of changes.
- In the copy, replace `.*(https://.*pull/)([0-9]+).*$` by `[#$2]: $1$2`.
- In the original, replace `(https://.*pull/)([0-9]+)` by `[#$2]`.
- Copy a section of new contributors.
- In the copy, replace `\* @([^ ]+) .*$` by `[@$1]: https://githhub.com/$1`.
- In the original, replace `@([a-zA-Z0-9]+)` by `[@$1]`.

To test:
1. Check that the CHANGELOG contents looks the same in the docs and in the repo (apart from the callouts) with clickable links to all PRs and contributors for v0.4.0.rc1.
2. Check that none of the lines with changes or new contributors have been removed.
* Revert to quiet callouts
Fix#973
Update the array of excluded directories and files to be:
- those that Jekyll excludes by default (since our `exclude` replaces Jekyll's defaults in Jekyll 3) and
- the others that the theme previously excluded, but omitting `vendor` – also ones that are no longer in the repo.
Excluding `vendor` was preventing HTML compression of the theme docs, since the layout used for compression is in `_layouts/vendor/compress.html`.
The change from one-line to multi-line YAML layout for the array of excluded files enhances readability. The addition of explanatory comments supports maintenance.
To test the effect of this PR on the theme docs:
- Build and serve the theme docs.
- Check that the HTML files are now compressed.
- Check that the last example of code with line numbers has incorrect formatting.
(This PR cannot affect sites that use the theme as a gem or as a remote theme, since we don't include our `_config.yml`.)
* Make CHANGELOG urls clickable
- Add link reference definitions for PRs and new contributors in v0.4.0.rc2
- Replace inline urls by shortcut link references
- Add front matter so the page appears in the navigation
- Change the link to the CHANGELOG on the home page
The CHANGELOG contents should look the same in the docs and in the repo (apart from the callouts) with clickable links to PRs and some contributors.
The urls shown in the changes in v0.4.0.rc1 (and previous releases) haven't yet been made clickable – it would be too tedious and error-prone to do it manually.
* Make CHANGELOG urls clickable
- Add a callout
An occurrence of `grandchild` was miss-spelled `grand_child` (!).
That caused omission of the `active` class in the link in the nav panel for all grandchildren.
This bug was discovered using `diff` to compare the generated sites built using v0.4.0.rc1 and commit 4396b6b1c836f354bb7aa7edc1a06a49f137d615 on the fix-nav-performance PR branch.
