Liquid markup sorting the output - html

I am trying to display a list of all articles using liquid markup. I've got this code which displays them properly, however I want to be able to sort by the modified date descending (most recent article on top). How can this be accomplished?
I was thinking that perhaps I need to create a new array with all articles in it and then sort that, but I am not sure how to do that. Also note that I want to sort ALL of my articles by date, not just within each folder.
{% for category in portal.solution_categories %}
{% if category.folders_count > 0 %}
{% for folder in category.folders %}
{% for article in folder.articles %}
{{ article.title }} - {{ article.modified_on | short_day_with_time }} <br>
{% endfor %}
{% endfor %}
{% endif %}
{% endfor %}
Thanks!

You can use a variable to sort the list of articles and then iterate that variable.
{% for category in portal.solution_categories %}
{% if category.folders_count > 0 %}
{% for folder in category.folders %}
{% assign sorted = (folder.articles | sort:date) %}
{% for article in sorted %}
{{ article.title }} - {{ article.modified_on | short_day_with_time }} <br>
{% endfor %}
{% endfor %}
{% endif %}
{% endfor %}

Liquid/Jekyll: How to check for no posts when one has two or more conditions?

I am having trouble understanding how I might show a "no posts exist" message for a particular conditional statement with two variables.
In this example, let's say I have a collection of "animals" - on a particular page, I'd like a section that displays "primates that are herbivores":
{% for animal in site.animal %}
{% if animal.species == "primate" and animal.type == "herbivore" %}
{{ animal.content }}
{% endif %}
{% endfor %}
What I'd like to do is something like this (pseudocode):
{% if POSTS_EXIST_FOR_THIS_COMBO: (animal.species == "primate" and animal.type == "herbivore") %}
{% for animal in site.animal %}
{% if animal.species == "primate" and animal.type == "herbivore" %}
{{ animal.content }}
{% endif %}
{% endfor %}
{% else %}
There are no posts for this category.
{% endif %}
Note: This differs from examples like this, because I have two parameters to check. Can someone offer a suggestion about the syntax?
I think you can do the following where you at first filter all by species=primate from site.animal and then filter by type=herbivore from that pool and then check if the result exists.
{% assign animals = site.animal | where:"species","primate" | where:"type","herbivore" %}
{% if animals %}
{% for animal in animals %}
{{ animal.content }}
{% endfor %}
{% endif %}
Hope this helps.

Jekyll nested include with for loop

I'd like to use a {% for %} loop in an included file, to avoid repeating logic to create the loop array (it's an assign with multiple where_exps).
But I'd like to use different content depending on where I include the loop, so sometimes I will do this:
{% for i in a %}
<li>{{ i.name }}</li>
{% endfor %}
and sometimes:
{% for i in a %}
<loc>{{ i.url }}</loc>
{% endfor %}
How can I achieve this? So far I have to put each of the inner contents in their own template, so I would have files like below, but I'd like to avoid the extra template files, and just keep that content in the appropriate main file:
html_template.html:
<li>{{ i.name }}</li>
xml_template.xml:
<loc>{{ i.url }}</loc>
page_loop.html:
{% assign a = "logic I don't want to repeat" %}
{% for i in a %}
{% include {{ include.inner_template }} %}
{% endfor %}
html_main.html:
{% include page_loop.html inner_template="html_template.html" %}
xml_main.xml:
{% include page_loop.html inner_template="xml_template.xml" %}
It would probably be another more elegant (?) solution developing a plugin, but quickly modifying your code, in _includes/page_loop.html:
{% assign a = "something" %}
{% for i in a %}
{%if include.type == "name"%}
<li>{{ i.name }}</li>
{%else if include.type == "url"%}
<loc>{{ i.url }}</loc>
{%endif %}
{% endfor %}
Then each time you include page_loop.html pass an additional parameter specifying which type of output you want:
{% include page_loop.html type="name" %}
or
{% include page_loop.html type="url" %}

How to loop through categories in a Jekyll collection

I'm trying to loop through categories that have been added to collection posts. For the default 'posts' section it's as easy as:
{% for category in site.categories %}
{{ category }}
{% endfor %}
But I can't seem to get this working for my collection. I thought it would be something along the lines of:
{% for category in my_collection.categories %}
{{ category }}
{% endfor %}
But that doesn't seem to work. Any help would be appreciated.
for anyone needing the answer to this...I've managed to solve this by adding all unique 'my_collection' categories to an array then looping through that. Here's the code:
<!-- create categories array-->
{% assign categories_array = "" | split:"|" %}
<!--Add each unique 'my_collection' category to the array-->
{% for post in site.my_collection %}
{% for category in post.categories %}
{% assign categories_array = categories_array | push: category | uniq %}
{% endfor %}
{% endfor %}
<!--Output the categories-->
{% for category in categories_array %}
{{ category }}
{% endfor %}
you can grab the name of each category like so:
{% for category in site.categories %}
{{ category | first | strip_html }}
{% endfor %}
You first have to declare the collection
{%a assign col = site.COLLECTIONNAME %}
Then you can loop inside the collection
{% for cat in col %}
{{ col.name }}
{% endfor %}

include_relative post.path jekyll

I'm trying to put a number of related posts on a single page. The problem is that the included posts are all textile pages, using some {% highlight %} tags. When I try to include then via post.content, they don't get textilized (e.g, I see "{% highlight..." on the page).
I've tried a few different things:
This never gets textilized:
{% for post in site.tags.my_tag %}
{{ post.content | textilize }}
{% endfor %}
This (based on http://nateeagle.com/2011/08/31/jekyll-not-parsing-includes/) returns no content:
{% for post in site.tags.apidocs %}
{% capture included_post %}
{{% include_relative post.path %}}
{% endcapture %}
{{ included_post | textilize }}
{% endfor %}
Any ideas?
Bradley
Try
{% include_relative {{post.path}} %}

Any way to access directory nodes?

In Jekyll 2, suppose I have a collection named mycol and that it has a structure like this in the filesystem:
_mycol/
00-intro.md
01-preface/
00-intro.md
01-something.md
02-subsection/
00-intro.md
03-hello.md
02-section/
00-intro.md
Is there any way to do have inner loops and detect if the current item is a directory or actual data?
Here's an example of what I would like :
{% for d in site.mycol %}
{% if d.content %}
{{ d.content }}
{% else %}
{% for v in d %}
{% if v.content %}
{{ v.content }}
{% endif %}
{% endfor %}
{% endif %}
{% endfor %}
Is there any know way or hack to achieve this?
