CurrentLevel

CurrentLevel is a plugin for Pico CMS http://picocms.org that only parses the directory in which the currently requested file resides while building the auto-generated menu.

In addition, CurrentLevel adds a (very) basic twig function to generate breadcrumbs.

(And it works with PicoEdit ;) )

Credits

This plugin is based on @bigicoin's PicoTooManyPages.

Installation

Simply drop CurrentLevel into Pico CMS's plugin directory. Then open config/config.php and add:

$config[ 'CurrentLevel.enabled' ] = true;

Effect in templates

{{ pages }} now only holds the files that are in the same (sub)directory as the currently requested file. In addition if there are any subdirectories with an index.md those will be contained as well.

Example:

/index.md
/about.md
/contact.md
/blog/index.md
/blog.../
/archive/index.md
/archive/2014
/archive/2014/..
/archive/2015/index.md
/archive/2015/..
/archive/2016/index.md
/archive/2016/..
/archive/2017/index.md
/archive/2017/..

If https://your.page.domain/contact is called, {{ pages } will hold index, about, contact, blog and archive (because the latter subdirectories contain index.md files).

If https://your.page.domain/archive is called, {{ pages } will hold archive/index, archive/2015, archive/2016 and archive/2017 but not archive/2014.

If you don't want the current level's index file to appear use something along:

{% set currentpath = current_page.id|split('/') %}
{% for page in pages if page.title %}
	{% set pagepath = page.id|split('/') %}
	{% if pagepath|last != 'index' or pagepath|length != currentpath|length %}
		<a href="{{ page.url }}">{{ page.title }}</a>
	{% endif %}
{% endfor %}

Using breadcrumbs

A crude example:

<nav role="navigation">
	<ul>
		<li>
			<a href="{{ base_url }}">Start</a>

				{% set crumbs = breadcrumbs(current_page.id) %}

				{% for foldername, folder in crumbs %}
					<ul>
						<li>
							<a href="{{ base_url }}?{{ folder }}">{{ foldername }}</a>
				{% endfor %}

				<ul>

				{% for page in pages if page.title %}
					<li class="{% if page.id == current_page.id %}active{% endif %}">
						<a href="{{ page.url }}" data-shortcut="{{page.meta.shortcut}}">
							{{ page.title }}
							{% if page.meta.shortcut %}
								<span class="shortcut">{{page.meta.shortcut|replace({'+':' '})}}</a>
							{% endif %}
						</a>
					</li>
				{% endfor %}

				</ul>

				{% for folder in crumbs %}
						</li>
					</ul>
				{% endfor %}

		</li>
</nav>

If you don't want to include the current level's index.md (because it's included in the breadcrumbs):

<nav role="navigation">
	<ul>
		<li>
			<a href="{{ base_url }}">Start</a>

				{% set crumbs = breadcrumbs(current_page.id) %}
				{% set currentpath = current_page.id|split('/') %}

				{% for foldername, folder in crumbs %}
					<ul>
						<li>
							<a href="{{ base_url }}?{{ folder }}">{{ foldername }}</a>
				{% endfor %}

				<ul>

				{% for page in pages if page.title %}
					{% set pagepath = page.id|split('/') %}
					{% if pagepath|last != 'index' or pagepath|length != currentpath|length %}
					<li class="{% if page.id == current_page.id %}active{% endif %}">
						<a href="{{ page.url }}" data-shortcut="{{page.meta.shortcut}}">
							{{ page.title }}
							{% if page.meta.shortcut %}
								<span class="shortcut">{{page.meta.shortcut|replace({'+':' '})}}</a>
							{% endif %}
						</a>
					</li>
					{% endif %}

				{% endfor %}

				</ul>

				{% for folder in crumbs %}
						</li>
					</ul>
				{% endfor %}

		</li>
</nav>
