Jekyll variable site.static_files is null - jekyll

I have an ultra simple Jekyll site that builds without error and Jekyll variables seem to be populated as expected except site.static_files which is null, despite there being a bunch of static files.
Here is a link to the source code. And here is a link to the output.

Edit:
Github pages uses Jekyll 1.5 and static_files are only available since version 2.0.0 (see history)
Edit #2 08-24-14
Github is currently at 2.2.0, so we can use site.static_files

Fail build if two posts resolve to the same permalink in Jekyll

In my Jekyll site I have a permalink structure like this in _config.yml:
permalink: /blog/:title:output_ext
And I have two posts (in _posts) that resolve to the same permalink silently, for example:
2020-10-15-my-post.md
2020-10-16-my-post.md
Only one is written to _site/blog/my-post.html.
Is there a way to halt the building of the site, and throw an error, if two posts resolve to the same permalink (and then, one post overwriting the other)?
The Jekyll CLI has a command called doctor that outputs any deprecation or configuration issues with your site and, among other things, it detects when two posts resolve to the same permalink.
You can run it similarly to how you build your site today:
bundle exec jekyll doctor
In the example you gave in your question, jekyll doctor will show you an error message about a conflict between two pages, similar to this:
Configuration file: /your-website/_config.yml
Jekyll Feed: Generating feed for posts
Conflict: The URL '/your-website/_site/blog/my-post.html' is the destination
for the following pages: /your-website/_posts/2020-10-15-my-post.md,
/your-website/_posts/2020-10-16-my-post.md
When jekyll doctor finds a conflict like the above, its exit code will be non-zero which you can use to fail the build.

add subfolders to _includes directory in Jekyll

I'm trying to add folders inside the "_includes" directory on Jekyll. It doesn't work. I've tried adding an underscore to the folder but it doesn't work either. What am I doing wrong? I'm using Jekyll 3.7.0
The most useful link I found about it was this one
Here are some screenshots:
And the stacktrace is:
Incremental build: disabled. Enable with --incremental
Generating...
Pagination: Pagination is enabled, but I couldn't find an index.html page to use as the pagination template. Skipping pagination.
Liquid Exception: Could not locate the included file 'sidebar.html' in any of [".../_includes"]. Ensure it exists in one of those directories and, if it is a symlink, does not point outside your site source. in /_layouts/page.html
jekyll 3.7.0 | Error: Could not locate the included file 'sidebar.html' in any of [".../_includes"]. Ensure it exists in one of those directories and, if it is a symlink, does not point outside your site source.
I think I'm supposed to be able to use sub-directories. What am I doing wrong? Thank you in advance!
Apparently, I found the problem. I don't know why but Jekyll is somehow able to parse comments. It detected I had commented a piece of code referencing the old sidebar.html.
As #DavidJaquel mentions in a comment below, HTML comments <!-- --> are not stopping Liquid to parse our page content, so we should be using Liquid syntax:
{% comment %}
...
{% endcomment %}

Global variables in MkDocs

I have a documentation project made with MkDocs. I would like to define global variables in the configuration file (mkdocs.yml) to be used in the markdown pages (*.md).
Reading this issue, it seems it can be done by including an extra configuration in the mkdocs.yml file, for example:
extra:
version: 1.0
... and then, use that variable in page for example as follows:
---> My version: {{ config.extra.version }}
I tried that, but unfortunately it is not working in my example (no variable substution):
Am I doing something wrong?
Is is possible to make this work?
No, this is not possible at this time.
You say that you "use that variable in page". I'm assuming you mean a "Markdown" page. At this time template variables are not available in the Markdown pages. The template engine is not even run against the Markdown. The output of the Markdown parser is one of the variables passed to the template. For a more detailed explanation of how that works, see my answer to How do you include flask/jinja2 code inside a markdown file?.
Specific to MkDocs, there is an open issue (#304) discussing adding a feature to support some limited templating within the Markdown pages, but it is scheduled for post-1.0, so its not a top priority at this time.
The given answer is out of date as this can be done with plugins like macros or markdownextradata as mentioned above except you would just reference {{ version }}.
As an update, it is possible to insert the variables from the extra slot in mkocs.yml, exactly as you describe.
To make this work, you need to install the markdownextradata plugin.

VS Code, format HTML code with Twig or Swig tags

Is there a way to format correctly HTML in VSCode when we use Twig or Swig tags, like
{% if ... %} {%else%} {%endif%} {% for %} {%endfor%} {% include %}, etc...
For now code formatters remove all line breaks before and after those tags.
Was not able to find an suitable extension for that.. Neither a way to configure the internal code formatter.
I had the same problem and solved installing this extension:
Twig Language
Install it, restart the editor and ff you are on windows you can format with standard ALT + SHIFT + F.
Hope it helps.
I've been struggling SO MUCH with this, and finally found a fully working solution; so wanted to share it here. Follow the steps below and you should be good to go:
Download the Vs Code Extension Prettier Code Formatter. Pay close attention to grab this Prettier Package, as Visual Studio proposes several different Prettier Extension Packages.
In the Visual Studio Editor, go to Settings --> type "format" until the formatting settings pop up, and then select Prettier Code Formatter - esbenp.prettier-vscode as your default formatter. Do this for both the User as well as the Workspace tab, if not automatically done.
Next, you'll need to add the melody plugin used for the proper formatting of twig files using Prettier in Vs Code. This is actually a nodejs package, so you first need to install Node JS. It can occur that you will run into permission issues when installing node packages later on. To try to avoid this at max, install node using a nvm.
Now you can install the melody plugin. To do so, follow the instructions of the linked repository. Note that you previously need to install yarn if you don't have it already installed, via npm install --global yarn.
To hold project-specific formattings within your github repo / project, you can add a .vscode/settings.json file which holds the general prettier configs you're currently using in your project. That's pretty useful to share the prettier formatting settings across developers / repos.
Also add the .prettierrc file to your projects root, with the following content:
{
"printWidth": 80,
"tabWidth": 4,
"plugins": ["./node_modules/prettier-plugin-twig-melody"]
}
This defines the additional use of the above-mentioned plugin. You may adapt the configs according to your needs. You can either put your node_modules folder holding the package within it into your local project, or adapt the path as needed to wherever your melody plugin is located on your local machine.
FYI: The node_modules folder is normally not uploaded to project repos due to its size. Once you install node, you will automatically get that node_modules folder on your local machine. And when you then install the above-mentioned package, it should get installed into that node_modules folder.
Now add the Twig Syntax highlighting package from whatwedo. Now, VS Code should recognize Twig files when you open them. Verify this by opening a .twig file within VS Code and checking in the bottom right corner that the file is recognized as HTML (Twig). This will additionally highlight your swig tags.
To verify that everything's working properly, you can open the prettier terminal by clicking on Prettier at the bottom right in your VS Code. Now write some twig content into a .twig file and trigger the formatter. If no errors were reported in the console, and the console informs that the melody plugin is used for formatting; and of course the code has been properly formatted; you're good to go.
There is a built-in way nowadays; when you try to format a document you get forwarded to the extension page and a search for a formatter for a given file format. For Twig:
category:formatters twig
Twig Language 2 seems to be the go-to VS Code Twig extension with the best formatter as of now.
Something related to this, i did it by installing twig in vs code.
Open VS Code and
Ctrl+Shift+X
And get the twig extension and install it. Thanks.

Jekyll use config.yml values in the HTML

Is it possible to setup configuration values within the config.yml file and have them be printed within the HTML page within Jekyll? I would like to set the default title and description of my website within the config.yml file and have them printed out in the header of all my layouts.
Every template has a site variable, which contains the settings from _config.yml. For example, if you have something like my_setting: "string" in _config.yml, you can access the value in a template using {{ site.my_setting }}.
Note: if you are using jekyll serve, you will need to restart the process for changes to take place. Indeed, _config.yml is not reloaded with the watch option.
