Page Hierarchy

A [Pelican][1] plugin that creates a URL hierarchy for pages that
|
||
|
|
matches the filesystem hierarchy of their sources.
|
||
|
|
|
||
|
|
For example, to have the following filesystem structure of page
|
||
|
|
sources result in the URLs listed next to each file,
|
||
|
|
|
||
|
|
```text
|
||
|
|
└── content/pages/ # PAGE_DIR
|
||
|
|
├── about.md # URL: pages/about/
|
||
|
|
├── projects.md # URL: pages/projects/
|
||
|
|
├── projects/ # (directory)
|
||
|
|
│ ├── p1.md # URL: pages/projects/p1/
|
||
|
|
│ ├── p2.md # URL: pages/projects/p2/
|
||
|
|
│ └── p2/ # (directory)
|
||
|
|
│ └── features.md # URL: pages/projects/p2/features/
|
||
|
|
└── contact.md # URL: pages/contact/
|
||
|
|
```
|
||
|
|
|
||
|
|
you can use this plugin with the following Pelican settings:
|
||
|
|
|
||
|
|
```python
|
||
|
|
# pelicanconf.py
|
||
|
|
PAGE_URL = '{slug}/'
|
||
|
|
PAGE_SAVE_AS = '{slug}/index.html'
|
||
|
|
SLUGIFY_SOURCE = 'basename'
|
||
|
|
```
|
||
|
|
|
||
|
|
When generating the `url` and `save_as` attributes, the plugin
|
||
|
|
prefixes the page's `slug` by its relative path. Although the initial
|
||
|
|
`slug` is generated from the page's `title` by default, it can be
|
||
|
|
generated from the source file basename by setting the
|
||
|
|
`SLUGIFY_SOURCE` setting to `'basename'`, as shown in the settings
|
||
|
|
snippet above. The `slug` can also be set using [`PATH_METADATA`][2].
|
||
|
|
|
||
|
|
This plugin is compatible with [Pelican translations][3].
|
||
|
|
|
||
|
|
Parent and Children Pages
|
||
|
|
-------------------------
|
||
|
|
This plugin also adds three attributes to each page object:
|
||
|
|
|
||
|
|
- `parent`: the immediate parent page. `None` if the page is
|
||
|
|
top-level. If a translated page has no parent, the default-language
|
||
|
|
parent is used.
|
||
|
|
|
||
|
|
- `parents`: a list of all ancestor pages, starting from the top-level
|
||
|
|
ancestor.
|
||
|
|
|
||
|
|
- `children`: a list of all immediate child pages, in no specific
|
||
|
|
order.
|
||
|
|
|
||
|
|
These attributes can be used to generate breadcrumbs or nested
|
||
|
|
navigation menus. For example, this is a template excerpt for
|
||
|
|
breadcrumbs:
|
||
|
|
|
||
|
|
```html
|
||
|
|
<ul class="breadcrumb">
|
||
|
|
<li><a href="{{ SITEURL }}/" title="{{ SITENAME }}">
|
||
|
|
<i class="fa fa-home fa-lg"></i>
|
||
|
|
</a></li>
|
||
|
|
{% for parent in page.parents %}
|
||
|
|
<li><a href="{{ SITEURL }}/{{ parent.url }}">{{ parent.title }}</a></li>
|
||
|
|
{% endfor %}
|
||
|
|
<li class="active">{{ page.title }}</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
```
