I'm accessing a page variable in a jekyll loop like below:
```ruby
{% assign kind = page.categories | first %}
{% for post in site.categories.[kind] | limit: 5 %}
{% unless post.url == page.url %}
<a href="{{ site.baseurl }}{{ post.url }}" class = 'post-url'>
<img src = '{{ site.baseurl }}/assets/{{ post.image }}.jpg>
<h2 itemprop="name headline">{{ page.title | escape }}</h2>
<time >{{ post.date | date: date_format }}</time>
</a>
{% endunless %}
{% endfor %}
```
Although the page builds successfully it outputs an error saying Expected page id but found open_square in "post in site.categories.[kind] | limit: 5"
How can I avoid this add still be able to use the page.categories | first variable?
Use site.categories[kind] instead of site.categories.[kind]
There shouldn't be any dot after "categories"

I want to transform following Jekyll "reading time" calculator
<span class="reading-time">
{% capture words %}
{{ content | number_of_words | minus: 180 }}
{% endcapture %}
{% unless words contains “-” %}
{{ words | plus: 180 | divided_by: 180 |
append: “minutes to read” }}
{% endunless %}
</span>
into "page rating" with the following meta taken from page Front matter using following formula
{{ page.facebook }}
plus
{{ page.instagram }}
multiply
{{ page.age }}
divide
1000 000
multiply {{ content | number_of_words }}
divide
100 =
More details here
This can do the trick :
{% assign number_of_words = content | strip_html | number_of_words %}
{% assign social = page.facebook | plus: page.instagram %}
{% comment %}Two lines for readability, but can be chained on one line{% endcomment %}
{% assign Indexmod = social | times: page.age | divided_by: 1000000.0 %}
{% assign Indexmod = Indexmod | times: number_of_words | divided_by: 100 %}
Note :
the use of strip_html, this avoid counting html as words.
the use of 'divided_by: 1000000.0' to cast result to a Float
I am editing include/span with the following code pretend to be as "Jekyll page rating calculator with meta from Front Mater area" but it seems like some syntax missing an extra heading/lines to let calculation to display in left bottom round quotes. Now there is no value
See the sampl page
<span class="indexmod">
{% assign number_of_words = content | strip_html | number_of_words %}
{% assign social = page.facebook | plus: page.instagram %}
{% comment %}Two lines for readability, but can be chained on one line{%
endcomment %}
{% assign Indexmod = social | times: page.age | divided_by: 1000000.0 %}
{% assign Indexmod = Indexmod | times: number_of_words | divided_by: 100
%}
{% endunless %}
</span>
There are two reasons why this doesn't work:
The {% endunless %} in this include is missing a matching unless clause. Either add one or remove the endunless line.
The value of Indexmod is not printed. You can do that by adding {{ Indexmod }} after your calculations are done.
I want use bellow code to display custom date in my Jekyll site
{% assign m = page.date | date: "%-m" %}
{% case m %}
{% when '1' %}Januar
{% when '2' %}Februar
{% when '3' %}März
{% when '4' %}April
{% when '5' %}Mai
{% when '6' %}Juni
{% when '7' %}Juli
{% when '8' %}August
{% when '9' %}September
{% when '10' %}Oktober
{% when '11' %}November
{% when '12' %}Dezember
{% endcase %}
But I don't now where to put it (I tried in post.html but does not work)
I've made a template for this.
This template translate a date in a specific language. Here it's french but feel free to change month and day arrays.
This template can be used in an enumeration of post/page (eg: the index page) or in a post/page template.
When used in an enumeration, you need to pass the date to process
{% for post in site.posts %}
<li>
<span class="post-date">{% include custom_date_full_fr.html date = post.date %}</span>
<a class="post-link" href="{{ post.url | prepend: site.baseurl }}">{{ post.title }}</a>
</li>
{% endfor %}
Where used in a page/post template, you just have to include the template, as the page.date will already be available.
{% include custom_date_full_fr.html %}
custom_date_full_fr.html
{% if include.date %}
{% assign processed_date = include.date %}
{% else if page.date %}
{% assign processed_date = page.date %}
{% endif %}
{% comment %}-------- Test if we have a date to process --------{% endcomment %}
{% if processed_date %}
{% assign month = "janvier,février,mars,avril,mai,juin,juillet,août,septembre,octobre,novembre,décembre" | split: "," %}
{% comment %}------ Note : sunday is the first day in this array -------{% endcomment %}
{% assign day = "dimanche,lundi,mardi,mercredi,jeudi,vendredi,samedi" | split: "," %}
{% assign month_index = processed_date | date: "%m" | minus: 1 %}
{%comment%}----------------------------------------------
Here **minus: 0** is a trick to convert day_index from string to integer and then use it as an array index.
----------------------------------------------{%endcomment%}
{% assign day_index = processed_date | date: "%w" | minus: 0 %}
{%comment%}-------- Output the date ----------{%endcomment%}
{{ day[day_index] }} {{ processed_date | date: "%d" }} {{ month[month_index] }} {{ processed_date | date: "%Y" }}
{% endif %}

I am trying to share a single template in 2 other templates as follows:
_layouts/V2/post.slim
{% include V2/date_wrapper.html date_value=page.date %}
and
_includes/V2/footer/recent_posts.slim
| {% for post in site.posts limit: 5 %}
| <div class="w-bloglist-entry">
| <a class="w-bloglist-entry-link" href="{{ post.url }}">{{ post.title }}</a>
| <span class="w-bloglist-entry-date">
| <i class="fa fa-clock-o"></i>
| {% include V2/date_wrapper.html date_value=post.date %}
| </span>
| </div>
| {% endfor %}
This is the shared template:
_includes/V2/date_wrapper.html
{% assign d = include.date_value | date: "%-d" %}
{{ include.date_value | date: "%B" }}
{% case d %}
{% when '1' or '21' or '31' %}{{ d }}st,
{% when '2' or '22' %}{{ d }}nd,
{% when '3' or '23' %}{{ d }}rd,
{% else %}{{ d }}th,{% endcase %} {{ include.date_value | date: "%Y" }}
If I set this up using the template only in the post it works, however, no matter what I try I can not seem to get this to work in the footer in the for loop. The error is:
Liquid Exception: undefined method `data' for #<Jekyll::SlimPartialTag:0x007ffa549315b0> in _layouts/V2/post.slim
14:47:34 - ERROR - Jekyll build has failed
Thoughts? Is this possible in Jekyll?
I'm trying to figure out how to display the total number of posts in a category (or all together). I envision something like below, but can't quite figure it out. Did I miss something from the docs?
{% for post in site.categories.CAT %}
...do some counting
{% endfor %}
posts: {% number_of_posts %}
{% for post in site.categories.CAT %}
{{ post.title }}
{% endfor %}
# all posts
{{ site.posts | size }}
# posts in one category
{{ site.categories.CAT | size }}
{% for post in site.categories.CAT %}
{% capture post_count %} {{ post_count | plus: 1 }} {% endcapture %}
{% endfor %}
{{ post_count }}
