Peter Mosses	a4e4e312aa	Feature: Allow unlimited multi-level navigation (#1431) ... * Allow unlimited multi-level navigation This PR supersedes #462. The only user-level difference from #462 is that disambiguation of parent pages has to use either `grand_parent` or `ancestor` titles: the somewhat unnatural `section_id` and `in_section` fields are not supported. The implementation has been significantly simplified by the changes introduced in v0.7.0 of the theme. * Detect cyclic parenthood A page should not have a parent or ancestor with the same title. If it does, the location of the repeated link is marked by ∞, to facilitate debugging the navigation (and an unbounded loop leading to a build exception is avoided). * Add nav_error_report warning in main navigation When activated by `nav_error_report: true` in `_config.yml`, displays warnings about pages with the same title as their parent page or an ancestral page. * Cache site-nav with links to all pages The extra cached site-nav is used for determining breadcrumbs and children navigation, which may involve pages that are excluded from the main navigation. * Replace code for determining children by inclusion of components/nav/children.html * Update CHANGELOG.md --------- Co-authored-by: Matt Wang <matt@matthewwang.me>	2024-08-20 22:34:11 +02:00
Peter Mosses	8e38759613	Fix liquid variable leakage in navigation components (#1243) ... * Refactor nav, breadcrumbs, children_nav Fix #1118 Improve the modularity of building the nav-panel, breadcrumbs, and children-nav by making them independent. This also significantly simplifies the Liquid code. * Fix order of breadcrumbs * Update breadcrumbs.html Revert inclusion of single breadcrumb for top-level pages. * Update breadcrumbs.html * Update children_nav.html Revert to the previous layout in the HTML, to allow the use of `diff` to check the built site. * Update minimal.html Remove the previously required workaround involving `nav.html`. * Add docs pages about layouts The aim of the initial version of these docs pages is to illustrate the difference between the default and minimal layouts. * Update CHANGELOG.md	2023-05-09 17:57:26 +02:00
Matt Wang	2495d3e6bb	refactor: modularize site components (#1058) ... Hi everyone, this is a large refactoring PR that looks to **modularize site components** following the discussion in #959. At the top-level, it: - moves icons, the sidebar, header (navbar, search, aux links), footer, and mermaid components of the `default` layout into their own `_includes` - creates a new `minimal` layout that does not render the header or sidebar as a proof-of-concept for the composability of components - documents all existing and new layouts (including vendor code) in the "Customization" section An important goal of this PR is for it to be **just code motion and flexibility**: there should be **zero impact** on the average end user that only consumes the `default` theme. The next few sections go in-depth on each of the listed changes. ### new components The `default` layout contains a "list" of all relevant components. Importantly, some of these components have sub-components: - the header is split into the search bar, custom code, and aux links - the icons include imports different icon components, some of which are conditionally imported by feature guards There are also candidates for future splits and joins: - the sidebar could be split into navigation, collections, external link, and header/footer code - the "search footer" could be joined with other search code, which would make it easier to "include search" in one go; *however, this is a markup change* - @kevinlin1 has pointed out that there is some leakage between the sidebar (which computes parents/grandparents) and the breadcrumbs (which needs them to render). He's graciously added a bandaid fix to `minimal` (which does not render the sidebar). However, in the long term, we should either: - calculate this in a parent and pass the information to both components - change how this works entirely (which may happen with multi-level navigation) @pdmosses has done a great job outlining this and more in his [Modular Layouts test site](https://pdmosses.github.io/modular-layouts/docs/main/). ### minimal layout Based on @kevinlin1's use-case in just-the-class (see: his [Winter 2023 CSE 373 site](https://courses.cs.washington.edu/courses/cse373/23wi/)), we've created a first-class `minimal` layout that does not render the sidebar or header. In a [comment](https://github.com/just-the-docs/just-the-docs/pull/1058#discussion_r1057015039), Kevin has indicated that we can re-add the search bar in the minimal layout; however, it seems like this would be a code change. I think we should punt this to a future issue/PR. @pdmosses has also discussed the confusion of `minimal` as a layout and its meaning in inheritance. I've added a note in documentation to clarify the (lack of) inheritance relationship. ### documentation I've written documentation in the "Customization" page / [Custom layouts and includes](https://deploy-preview-1058--just-the-docs.netlify.app/docs/customization/#custom-layouts-and-includes) section explaining: - generally, that we use includes/layouts (and pointing to docs) - the `default` layout and its constituent components (with a warning about name collisions) - creating alternative layouts with `minimal` as an example - the inheritance chain of layouts and the vendor layouts that we consume I've also created (and linked to) a [minimal layout test](https://deploy-preview-1058--just-the-docs.netlify.app/docs/minimal-test/) that is currently a copy of the markdown kitchen sink but with the minimal layout. I think there's room to improve this in the future. ### future work I think there's a lot we can do. Let me break this into various sections. Potential follow-ups before `v0.4.0`: - re-including search in `minimal` (anticipating a minor code change) - fixing the leakage of parent/grandparent information between the sidebar and breadcrumbs (anticipating no end-user code change, but good to evaluate separately and discuss) - heavily document this in the migration guide (#1059) and in our RC4 release docs - improve semantic markup for components (ex `main`, `nav`) Related work in later minor versions: - split up components into smaller components - allow users to easily customize new layouts using frontmatter (see @kevinlin1's [comment in #959](https://github.com/just-the-docs/just-the-docs/issues/959#issuecomment-1249755249)) Related work for `v1.0` (i.e. a major breaking change): - rename and better categorize existing includes - standardizing the "custom" includes - moving other components to the `components/` folder (ex `head`, `nav`) - potentially: less confusing naming for various components - potentially separate the search and header as components, so that they are completely independent Tangentially related work: - more flexible grid (see @JPrevost's [comment in this PR thread](https://github.com/just-the-docs/just-the-docs/pull/1058#issuecomment-1363314610)) - a formal [feature model](https://en.wikipedia.org/wiki/Feature_model) of JTD, documenting feature dependence (see @pdmosses's [comment in this PR thread](https://github.com/just-the-docs/just-the-docs/pull/1058#issuecomment-1365414023)) - better annotate new features (motivated by writing these docs) - we should add "New" to new features :) - we should note when a feature was introduced (I think this is a core part of most software documentation) - we should annotate things that are "Advanced" in so far as the average Just the Docs user will not use them / they require significant Jekyll knowledge --- Closes #959.	2023-01-07 16:08:45 -08:00
