I am trying to change the way that posts are displayed on my home page, but no matter what I do, changes don't appear to get reflected at all. Here are the steps that I followed:
_config.yml
JB :
version : 0.2.13
posts_collate :
provider : "custom"
Then I created the file _includes/custom/posts_collate with the exact same content as _includes/JB/posts_collate but with a few tweaks.
My original posts_collate starts off like this:
{% if site.JB.posts_collate.provider == "custom" %}
{% include custom/posts_collate %}
{% else %}
{% for post in posts_collate %}
{% capture this_year %}{{ post.date | date: "%Y" }}{% endcapture %}
{% capture this_month %}{{ post.date | date: "%B" }}{% endcapture %}
{% capture next_year %}{{ post.previous.date | date: "%Y" }}{% endcapture %}
{% capture next_month %}{{ post.previous.date | date: "%B" }}{% endcapture %}
Am I editing the right file? What could be the cause for my changes not getting reflected in the custom folder?
In case you haven't fixed it yet, here's the info that works below that I tested. You set up your _config.yml correctly.
Two other things you need to do.
Update the include path to be 'JB/custom/posts_collate' as it is referencing the path from _includes/
Stop and restart the server with $ jekyll --server so it can parse your updated _config.yml file as well

I have a very noob question. I want to create a page, where will be presented all posts from some category. I understand, that I should write some {% include %} tag, but I could not understand which.
I have:
{% for post in site.posts %}
<!-- check if post comes from one of page categories-->
{% assign PostAndPageCategories= page.categories | concat: post.categories %}
{% capture all_cat %}{{ PostAndPageCategories | join: "," }}{% endcapture %}
{% capture unique_cat %}{{ PostAndPageCategories |uniq | join: "," }}{% endcapture %}
{% if all_cat != unique_cat %}
<!-- END check if post comes from one of page categories-->
{% include archive-single.html %}
{% endif %}
{% endfor %}
Obviously, this code shows me posts with teasers, but I need to display the whole post.
How should I change line {% include archive-single.html %}?
I found {{post.content}} instead of {% include archive-single.html %} work fine for me.
I need to be able to compare a value in each of the markdown files in a folder called in_media to the user_id of the current page stored in a _users folder and only display the post title that have that value from the in_media folder.
User markdown file in _users folder
---
user_id: 123
title: bob
---
Post markdown from in_media folder
---
users: 123
---
I tried the following:
{% for this_user in site.in_media %}
{% for user in page.user %}
{% if this_user == user.user_id %}
<li><a href="{{ post.external_link }}">{{ post.title }}</a </li>
{% endif %}
{% endfor %}
{% endfor %}
However, this is not returning anything
Try this way:
{% for post in site.in_media %}
{% if post.value == page.title %}
<li>{{ post.title }}</li>
{% endfor %}
{% endfor %}
I'm not sure that you can use external_link, never heard of it. Maybe you'll need to build permalink manually - depending on your _config.xml.
Also note the collection should be properly set up to work with permalinks.
I'm creating a style guide in Jekyll and using Collections to define different elements of the guide. For example, headings, lists, etc.
I'm trying to separate the Sass into files that match up with the partials, one to one, and I'd like to render the Sass files as part of each collection.
So, something like:
{% if _includes/_sass/{{ entry.title | append: ".scss"}} %}
{% highlight sass %}
{% include _includes/_sass/{{ entry.title | append: ".scss" }} %}
{% endhighlight %}
{% endif %}
Basically, what I want is "Include a file in this directory that has the same name as this entry in my collection. If it doesn't exist, don't break."
How do I do this? I've explored storing the file path in a variable but can't seem to get that to work.
Thanks in advance.
It can be done.
This works on Jekyll 3 but it can certainly be ported to Jekyll 2.
Starting from a base install (jekyll new)
_config.yml
collections:
guide:
sasssamples:
Style guide files
Our samples will be grouped in the _guide collection.
Example file : _guide/header/header1.hmtl
---
title: Header level 1
---
<h1>Header level 1</h1>
SCSS samples
We want our SCSS samples to be included in our css/main.scss and use variables defined in our other SCSS files. Our samples will be integrated at the end of our css/main.scss
We don't want our SCSS samples to render as css so no .scss extension. Switch to .txt extension
We want to access SCSS samples from a list. Let's put them in a sasssamples collection.
Example file : _sasssamples/header/header1.txt
---
---
h1{
color: $brand-color;
border: 1px solid $brand-color;
}
SCSS samples integration
Add this code at the very end of you bootstraping scss file (css/main.scss on a base Jekyll install)
css/main.scss

{% comment %} Try to find a SCSS sample with equivalent path {% endcomment %}
{% assign scssSample = scssCollection.docs | where: 'path', scssPath | first %}

{% if scssSample != nil %}

{% highlight css %}{{ scssSample.content }}{% endhighlight %}
{% endif %}

{% endfor %}
Done!
Seems it only miss on assigning the correct path
{% if _includes/_sass/{{ entry.title | append: ".scss"}}
Need to be replaced to relative path to the scss file:
{% assign scssPath = 'relative/path/to/your/scss/' %}
{% if {{ entry.title | append: ".scss" | prepend: scssPath }} != nil %}
Google Webmaster tools complains about pages with the same title. I'm trying to figure out how to make my blog index pages have different titles (by including the page number)
I set my titles through frontmatter so they are available to my base template.
I can't set the title in frontmatter to include the page number, since frontmatter doesn't evaluate variables.
I also tried {% assign page.title = 'freestyle' %} but found out page.title isn't really a variable
I created a new variable called titleOverwrite which correctly gets the data I want. Unfortunately it isn't scoped in my base template.
How can I get the titles to include the blog page number?
Here is what I tried:
Base Template
{% assign title = page.title %}
{% if page.overwriteTitle %}
{% assign title = page.overwriteTitle %}
{% endif %}
<title>{{title}} {{page.subtitle}}</title>
blog index.html
{% assign overwriteTitle = page.title | append: ' Page ' | append: paginator.page %}
<p>prove it works </p>
<p> {{ overwriteTitle }} </p>
_includes/head.html or any template affecting title tag
We test the paginator variable which is only present in paginated pages :
<title>
{% if paginator %}
{% assign overwriteTitle = page.title | append: ' Page ' | append: paginator.page %}
{{ overwriteTitle }}
{% else %}
{% if page.title %}{{ page.title }}{% else %}{{ site.title }}{% endif %}
{% endif %}
</title>
How can I use Jekyll to test for the existence of a file?
To clarify, I want to run an {% if %} statement to check if an image file exists with the same name as the page I am on.
On my page in the YAML front matter:
----
reference-design: true
----
In my layout:
{% if page.reference-design %}
{% assign filename = page.path | remove_first: '.html' %}
<!-- How can I check if file actually exists? -->
<img src="images/reference_designs/{{ filename }}.png">
{% endif %}
As of Jekyll 2, all site files are available via site.static_files. You can use this to check if a file exists. For example:
{% for static_file in site.static_files %}
{% if static_file.path == '/favicon.ico' %}
{% assign favicon = true %}
{% endif %}
{% endfor %}
I had a similar problem to solve, but specifically looking for videos that matched the a specific directory / filename based on the markdown file.
Using file.size allowed me to test if the file (actually) exists.
{% for video in site.video-demos %}
{% assign path = page.id | replace: page.slug , "" | prepend: '/assets/media/video' | append: video.directory | append: page.slug | append: ".mp4" %}
{% assign file_exists = site.static_files | where: "path", path %}
{% if file_exists.size != 0 %}
{% include video-player.html filename = path title = video.title %}
{% endif %}
{% endfor %}
It loops through an array from my config to get part of the directory structure:
video-demos:
- title: iOS Voiceover Safari
directory: ios/
- title: Android Talkback Chrome
directory: android/
- title: Windows Jaws Chrome
directory: jaws/
- title: Windows NVDA Chrome
directory: nvda/
- title: MacOS Voiceover Safari
directory: macos/
This plugin worked for me: https://github.com/Wolfr/jekyll_file_exists
After you install it, you can use it like:
{% if page.reference-design %}
{% assign filename = page.path | remove_first: '.html' %}
{% capture img_exists %}{% file_exists {{ filename }}.png %}{% endcapture %}
{% if img_exists == "true" %}
<img src="images/reference_designs/{{ filename }}.png">
{% endif %}
{% endif %}
