Octopress plugin to display tag clouds. Based on https://gist.github.com/1577100 by tokkonopapa

Version: 0.3

Getting Started

This won't work without a plugin to generate some tag pages. See https://github.com/robbyedwards/octopress-tag-pages for a plugin to take care of this.

Put tag_cloud.rb in the /plugins folder. Then add {% tag_cloud %} where the tag cloud should appear. A couple of sample files are included to demonstrate basic usage, and several options are provided to control the appearance of the tag cloud.

Usage

Defines a tag_cloud tag that is rendered by Liquid into a tag cloud:

<div class="cloud">
    {% tag_cloud %}
</div>

The tag cloud itself is a collection of anchor tags, styled dynamically with the font-size CSS property. The range of values, and unit to use for font-size can be specified with a very simple syntax:

{% tag_cloud font-size: 16 - 28px %}

The output is automatically formatted to use the same number of decimal places as used in the argument:

{% tag_cloud font-size: 0.8  - 1.8em  %}  # => 1
{% tag_cloud font-size: 0.80 - 1.80em %}  # => 2

Tags that have been used less than a certain number of times can be filtered out from the tag cloud with the optional threshold parameter:

{% tag_cloud threshold: 2 %}

The ouptput can be limited to a certain number of the most frequently occurring tags when the sort method is alphabetical or frequency; i.e., {% tag_cloud limit: 8 %} => results in a tag cloud with the eight most frequent tags sorted alphabetically.

When the sort method is random then output is randomly sorted and limited to @limit items. Setting the limit parameter to zero (the default) will display all tags.

The output can be sorted in three ways:

{% tag_cloud sort: freq|rand|alpha %}

• freq will sort by the frequency of the tag`s occurrence
• rand will sort randomly each time the cloud is generated
• alpha (the default) will sort the tags in alphabetical order

An optional order parameter can also be set, which will change the sort order:

{% tag_cloud sort: freq|rand|alpha [asc|desc] %}

By default, alphabetical sorts will be asc, and frequency sorts will be desc. The order parameter has no effect on random sorts.

The style parameter provides a basic way to alter the html that is generated by the plugin:

{% tag_cloud style: list|para [{:separator}] %}

• list wraps each anchor tag in an <li> tag for presenting the list as an (un)ordered list. The {% tag_cloud %} block needs to be enclosed in either a <ol> or a <ul> block where it is included in the site's templates. list is the default option. The optional separator will have no effect when the list option is used
• para removes the enclosing <li> tags and separates each item with an optional separator (indicated by :separator above). By default the separator is a comma followed by a space. An alternate separator can be indicated by wrapping the new separator inside curly brackets ({}) following the para option, i.e., {% tag_cloud style: para { — } %}

Multiple parameters can be separated by a comma:

{% tag_cloud font-size: 50 - 150%, threshold: 2 %}
