Theme Installation and Usage

Jun 8, 2016 on Jekyll Theme GitHub Installation

This is a blog template for a static site generator named Jekyll based on a Ghost template named Decent. If you like to see the theme in production have a look at jwillmer.de.

Screenshots

Installation

To generate/host the blog you need to install Jekyll.
For the plugins (github-pages) you need to install Bundler: gem install bundler
- Open a command prompt and install the plugins (github-pages): bundle install
- On Windows you will propably get an exception. To solve it you can read How to install Jekyll and pages-gem on Windows (x64) or you remove the plugins by deleting the Gemfile and delete all gems: from the _config.yml

Build

To build the static site you can use the generated site folder that Jekyll creates when you use jekyll serve or you can build it explicitly with jekyll build.
If you like to use GitHub to host your blog you can fork this project and publish the code to gh-pages. GitHub has jekyll included and will generate the site for you.

User Content

Blogposts can be written in Markdown.

The folder for blog content is _posts
For author details you need to modify _data/authors.yml
For site properties (like the name) you need to modify _config.yml and robots.txt
For the about page you need to modify the about.md in _pages

After modifying *.yml files you need to restart jekyll to take effect.

YAML Custom Features

Apr 6, 2016 on Jekyll YAML Features Explained

In this short post I changed the title that is displayed on the front page from YAML Custom Features to YAML Features.

---
title:             "YAML Custom Features"
menutitle:         "YAML Features"
---

I also added a redirect to this post. If you browse to YAML-Feature-Redirect you should be redirected to this page. This only works if you have not removed the plugins.

---
redirect_from:     "/YAML-Features-Redirect"
---

If you like to redirect from multible sources you can specify it as an array.

---
redirect_from:  
  - "/YAML-Features-Redirect/"
  - "/blog/old-category/YAML-Features/"
---

I also changed the cover image for this block via YAML.

---
cover:         /assets/mountain-alternative-cover.jpg
---

To generate keywords for the search engines I use the tags that you specify in the post. If you are writing a page you need to specify keywords instead of tags.

---        
tags:          Jekyll YAML Features Explained  #Only used in posts!
keywords:      Jekyll YAML Features Explained  #Only used in pages!
---

Post will be sorted by category on the front page. This is how you define the category in YAML.

---        
category:     Readme
---

On a page I have additional options. For instance I can hide the page from the menu by setting the visible tag to false.

---        
visible:       false     
---

If I like to have the page in the menu I can add weight to the page in order to specify a position in the menu.

---        
weight:       5  
---

The default language of your blog is defined in the _config.yml file but if you like to write a post/page in another language you can use the language attribute. This will specify that you are using another language on this page for search engines. Please use on of the language codes as value.

---        
language:       en  
---

You can enable disqus comments in posts by adding comments to the page. To configure the disqus forum you need to modify the disqus_shortname in the _config.yml file.

---        
comments:       true  
---

Additional features, that can be specified, can be found in the YAML Front Matter documentation.
