I have a little problem trying to generate quotes in a html file throught a rmarkdown. Actually, I would like to generate some jinja inside my html and there come the problem.
If I do not escape the quote:
{% extends "base.html" %} in rmarkdown become
{% extends “base.html” %} in the html file which produce an error.
And if I do escape the quote:
{% extends \"base.html\" %} in rmarkdown become
{% extends "base.html" %} in the html file which produce an error too.
What is the solution ?
Thanks by advance !
I got the answer after a discussion on another channel.
It is necessary to add a option in the yaml below the html_document:
self_contained: false
and use escape quotes \" to avoid smart transformations.

I'd like to create something like a shortcode for a blockquote in Jekyll. It should include the quote source in a nicely formatted way.
The shortcode could look like this:
{% quote author="My Author" %}
This is the quoted content
spanning multiple lines
And paragraphs
{% endquote %}
What's the best way to achieve this in Jekyll? Can it be that there is no way to provide multiple arguments to a Jekyll tag plugin?
I have found a blog post that provides multiple attributes using string concatenation or JSON.
My Research
I have found two systems in Jekyll that can be used similar to shortcodes:
HTML Includes
Custom Tags
To summarize, both methods only provide a single attribute to the Ruby code, the content. Below, you will find the limitations of both solutions.
HTML Includes limiations
https://jekyllrb.com/docs/includes/
An include in use looks like this:
{% include note.html content=download_note %}
It is possible to use content from captures for parameters, so we could create the following include file:
<blockquote>
{{ include.quote | markdownify }}
<p><em>{{ include.author }}</em></p>
</blockquote>
And use it in a blog post like this:
{% capture quote %}
This is the quote content
spanning multiple lines
And paragraphs
{% endcapture %}
{% include quote.html quote=quote author="My Author" %}
It works, but in my opinion, it's not really a nice approach to use when writing blog posts.
Custom Tags limiations
https://jekyllrb.com/docs/plugins/tags/
Sounds promising, but the documentation only shows two ways to use them:
{% render_time page rendered at: %}
and
{% render_time %}
page rendered at:
{% endrender_time %}
I have this Liquid template which looks like this:
# /_includes/slideshow.html
{% for image in {{ include.images }} %}
...
{% endfor %}
which I'm trying to use with a YAML file (for my Jekyll site) like this:
# /index.md
{% include slideshow.html images='site.data.homepage_images' %}
The reason I see this failing is because my include variable {{ include.images }} resolves to a string within the for loop. Is there a different way to accomplish this? I'm still rather new to Liquid, YAML, Jekyll, and well, web development altogether, so any help in doing this is much appreciated!
(Note: the problem goes away if I replace {{ include.images }} with site.data.homepage_images.)
Additionally, the reason why I'm doing this (and why that crude fix isn't the solution I'm looking for) is for the ability to inject my image slideshow elsewhere around my site. It'd save a lot of code to abuse my include variable in this way.
Correct syntax in for loop is : {% for image in include.images %}
I have recently seen one HTML page.The code is embed with curly braces.Values for tags and loops are closed by curly braces.
{% if authenticated %}
<h1>Current User</h1>
<p>{{user}}</p>
{% else %}
<h1>Current User</h1>
<p>None</p>
{% endif %}
What is the actaul use of these type of code?
Is HTML embedded with any other language?
This may be Django script templates. Find more here.
This looks like the HTML is enriched with underscore.js or a similar templating engine.
It's used for displaying JavaScript data in your HTML without the need to know how JavaScript works.
Say I have a template layout saved in template.html. This template includes a banner, side navigation, content container, and footer. Can I use flask to break up these page elements in such a way that I can have files such as banner.html, sidenavigation.html, etc. and render these different files within template.html?
From: http://jinja.pocoo.org/docs/templates/#include
template.html
{% include 'banner.html' %}
{% include 'sidenavigation.html' %}
{% include 'content.html' %}
{% include 'footer.html' %}
By default, Flask uses Jinja2 as its template engine. See Jinja's Template Designer Documentation how it's done.
Before you start, you need to write these components separately to other html files as pure html. For example, these files shouldn't contain any jinja syntax. After that, according to the documentation, you can easily import them into your template.html file by calling {% include 'filename.html' %} code.
Is there a way I can load a jinja2 template from within another template file? Something like
{{ render_template('path/to/file.html') }}
I have some snippets which I want to reuse, so it's important for me to have this functionality.
{% include "file" %} does this. See the jinja2 docs for more information.
Use either the extends tag or the include tag, depending on how you want to design your multi-file views.
You should make template files with {% macro -%}s and use {% import "file" as file %} to use the macros in other template files. See the docs.
Here is an example:
<!- in common_macros.html ->
{% macro common_idiom1(var1, var2, ... varN) -%}
<!- your idiom, where you can use var1 through varN ->
{%- endmacro %}
<!- in my_template.html ->
{% import "common_macros.html" as idioms %}
{{ idioms.common_idiom1(a, b, ... N) }}
Specifically this answer allows the OP to pass arguments to his macros, similar to the behavior he desired like how render_template behaves (simply including the file as previous answers have stated above does not achieve the same behavior as render_template).
This is generally better than making a fresh template for every idiom, or than using inheritance, which is a special case solution (what if you want to use the snippet multiple times in one template)?
