I wanted to create a simply include which simplifies creating a carousel. So I was looking for the syntax to give a list of image urls as a parameter. However I couldn't find anything about this.
{% include carousel.html images=WHAT HERE? %}
You can create a list as a string then convert it into an array inside your snippet. This is the way I would do it.
{% assign urls = 'url1.jpg,url2.jpg,url3.jpg' %}
{% include carousel.html images=urls %}
Of course this is the same as:
{% include carousel.html images='url1.jpg,url2.jpg,url3.jpg' %}
carousel.html
{% assign images = include.images | split: ',' %}
{% for image in images %}
{{ image }}
{% endfor %}

I'm using sphinx and auto-summary to create my documentation. However, for each module a I want to generate customized list of references. However, to do that, I need to pass the objname to ref directive. How can I achieve that?
{{ fullname | escape | underline}}
.. automodule:: {{ fullname }}
Items
-----
{% block classestab %}
{% if classes %}
{% for objname in classes %}
- :ref:` {{objname}} <{{objname}}>`_ // doesn't work
{%- endfor %}
{% endif %}
{% endblock %}
I've also trying to use a jinja variable to create headings for my documentation. However I don't know to achieve this. The code below will not work of course
{% block table %}
{% if classes %}
{% for objname in classes %}
{{objname}}

{%- endfor %}
{% endif %}

I'm trying to use relative_url in most of the links of my Jekyll theme, so if someone wants to have this theme working in a subdirectory he can do it.
I have a problem with the list of categories of the post, each of which should link to the archive.
In _layouts/post.html I have this code:
{% if site.data.settings.categories.active %}
{% include categories.html %}
{% endif %}
categories.html has this code:
<div class="categories">
<span><p>Categories:</p>
{% if post %}
{% assign categories = post.categories %}
{% else %}
{% assign categories = page.categories %}
{% endif %}
{% for category in categories %}
{{category}}
{% unless forloop.last %} {% endunless %}
{% endfor %}
</span>
</div>
Here's the problem:
{{category}}
Somehow, this returns the current post url.
{{category}}
This returns the correct link, but does not work in case the site is in a subdirectory.
Why it returns the post url?
There are multiple problems here.
First off, Liquid doesn't evaluate nested constructs.
Therefore, the following code:
{{ "/categories/#{{category | slugify}}" | relative_url}}
needs to be rewritten into:
{% capture url %}/categories/{{ category | slugify }}{% endcapture %}
{{ url | relative_url }}
Secondly, there is no global post object. Therefore {% if post %} is always going to evaluate to a negative. i.e., it is redundant.
I'm trying to see if it's possible to iterate a variable in Jekyll for a testimonial block I'm implementing for a Jekyll site. Basically, I'd like to have an icon be multiplied by the number dictated in my collection. Is this even possible with liquid markdown? Here's a snippet:
{% assign star = "<i class="icon-star"></i>" %}
{% assign star = star | times:{{ testimonials.stars }} %}
I'm thinking there's better ways to do this, but I was curious what I could get away with front matter.
To do it iterating, you can use a for loop appending the desired string to a variable:
{% assign star = '<i class="icon-star"></i>' %}
{% assign result = '' %}
{% for time in testimonials.stars %}
{% assign result = result | append: star%}
{% endfor %}
The key is to use a for block. You don't have to write multiple assign statements.
The following will render a star per the front matter key rating in any page using the code.
Modify the for bock as required.
{% assign star = '<i class="icon-star"></i>' %}
<div class="rating">
{% for count in (1..page.rating)) %}
{{ star }}
{% endfor %}
</div>

I want to use a value in my frontmatter to specify a data file to loop through, but I can't get this to work.
I have a data file in _data/sidebars/sidebar1.yml. It contains:
- first
- second
- third
On a page I have this frontmatter:
---
title: My page
sidebar: site.data.sidebar.sidebar1
---
I want to use this code:
{% for entry in page.sidebar %}
* {{entry}}
{% endfor %}
However, this doesn't work. I've tried a number of things (involving assign and capture tags to define the page.sidebar content, but nothing seems to work).
The only thing that works is to do this:
{% if page.sidebar == "site.data.sidebars.sidebar1" %}
{% assign sidebar = site.data.sidebars.sidebar1 %}
{% endif %}
{% for entry in sidebar %}
* {{entry}}
{% endfor %}
However, I would like to avoid this extra code with the if statement, since it's easy to forget this and I would like to automate this more.
Any ideas on how to make this work?
You have a typo in your front matter. It's :
sidebar: site.data.sidebars.sidebar1
not
sidebar: site.data.sidebar.sidebar1
You can even be less verbose.
In your front matter : sidebar: sidebar1
In your code :
{% assign sidebar = site.data.sidebars[page.sidebar] %}
{% for entry in sidebar %}
{{ entry | inspect }}
{% endfor %}
Assuming I have a list of tags: iFix_6.3, iFix_7.0, iFix_7.1, iFix_8.0, announcement, and so on... and I want to run an operation only on certain several tags. How can I check for these multiple values?
There is contains, but I'm looking for the opposite of it and for multiple values...
Here is an example where I actually filter out all posts that contain the iFix_6.3 tag, thus display all other posts. This actually does not work yet... plus needs to be extended to work for multiple tags.
// posts with iFix_xxx tag should be filtered from the main posts view.
{% assign postUpdates = site.posts | where_exp:"item", "item.tags != 'iFix_6.3'" %}
{% for post in postUpdates limit:10 %}
<div class="postItem inline">
<p class="postDate">{% if post.pinned %}<span class="glyphicon glyphicon-pushpin"></span>{% endif %}{{post.date | date: '%B %d, %Y'}}</p>
<p class="postTitle">{{post.title}}</p>
</div>
{% endfor %}
You can do this by building an array of excluded tags (excluded_tags) using split and a string of the comma-separated tags. Then for each post, you iterate on the post's tags. Check if the tag is in excluded_tags using contains, if it is then raise the flag filtered_out to not display the post, using the unless control flow tag.
{% assign excluded_tags = "iFix_6.2,iFix_6.3,announcement" | split : "," %}
{% for post in site.posts limit:10 %}
{% assign filtered_out = False %}
{% for tag in post.tags %}
{% if excluded_tags contains tag %}
{% assign filtered_out = True %}
{% break %}
{% endif %}
{% endfor %}
{% unless filtered_out %}
...
{% endunless %}
{% endfor %}
Seems unless would solve the case.
{% assign postUpdates = site.posts | where_exp:"item", "unless item.tags contains 'iFix_6.3'" %}
