What are some good ways to implement breadcrumbs on a Jekyll site?
I'm aware that there are single-level breadcrumbs in http://raphinou.github.com/jekyll-base/ but I'm looking for some good ways to have breadcrumbs on a Jekyll site when directories get to a depth of four or five levels.
(Yes, I'm well aware that Jekyll is primarily a blogging engine and that perhaps I shouldn't use it for a general purpose website, especially with many directory levels. I'm also aware of http://octopress.org but haven't found a suitable plugin.)
Based heavily on http://forums.shopify.com/categories/2/posts/22172 I came up with the following Jekyll layout for breadcrumbs, a variation of which you can see in action at http://crimsonfu.github.com/members/pdurbin . You should see the breadcrumbs "home » members »" at the top.
Here's my layout. Yes, it's ugly. I haven't studied Liquid much. Can you suggest a better way?
<html>
<head>
<title>{{ page.title }}</title>
<style type="text/css">
#bread ul {
padding-left: 0;
margin-top: 2px;
margin-bottom: 2px;
}
#bread ul li {
display: inline;
font-size: 70%;
}
</style>
</head>
<body>
<div id="bread">
<ul>
{% assign url = {{page.url}} %}
{% assign delimiter = '/' %}
{% capture allparts %}{{ url | replace: delimiter, ' ' }}{% endcapture %}
{% capture myFirstWord %}{{ allparts | truncatewords: 1 | remove: '...' }}{% endcapture %}
{% capture minusFirst %}{{ allparts | replace_first: myFirstWord, '' }}{% endcapture %}
{% capture mySecondWord %}{{ minusFirst | truncatewords: 1 | remove: '...' }}{% endcapture %}
{% capture minusSecond %}{{ minusFirst | replace_first: mySecondWord, '' }}{% endcapture %}
{% capture myThirdWord %}{{ minusSecond | truncatewords: 1 | remove: '...' }}{% endcapture %}
{% capture minusThird %}{{ minusSecond | replace_first: myThirdWord, '' }}{% endcapture %}

{% capture myFifthWord %}{{ minusFourth | truncatewords: 1 | remove: '...' }}{% endcapture %}
{% if myFirstWord contains '.html' %}

Answer
I have improved slightly on the answers given earlier. I have removed the unordered list and seperated the items with a character (forward slash). I have added a filter for 'index.html' and '.html', so urls like 'mysite.com/path/index.html' and 'mysite.com/path/item-name.html' are also supported. Finally I have capitalized the titles. This results in something that looks like this:
Home / Path / Item name
{% assign crumbs = page.url | remove:'/index.html' | split: '/' %}
<a href="/">Home</a>
{% for crumb in crumbs offset: 1 %}
{% if forloop.last %}
/ {{ crumb | replace:'-',' ' | remove:'.html' | capitalize }}
{% else %}
/ <a href="{% assign crumb_limit = forloop.index | plus: 1 %}{% for crumb in crumbs limit: crumb_limit %}{{ crumb | append: '/' }}{% endfor %}">{{ crumb | replace:'-',' ' | remove:'.html' | capitalize }}</a>
{% endif %}
{% endfor %}
PS. I have created an online resource for snippets like this: jekyllcodex.org/without-plugins
