Jekyll GitHub Pages Blog

Do you want to build your own site from scratch or generate one for your project? This guide could help you with Jekyll and GitHub Pages.

GitHub Pages

Before we start build our Jekyll site, we should do as follows in GitHub:

• Create a new empty repository, name is username.github.io; For example, my repository named chenweigao.github.io.
• In your home folder, clone this repository, using git clone
• If you have any questions about Git ,see my another post Git - To Use Git More Easily: Config, Branch and Rebase

Install

Take Ubuntu system as an example:

# Install
sudo apt-get install ruby jekyll

or this guide:

sudo apt-get install ruby ruby-dev build-essential
echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
echo 'export GEM_HOME=$HOME/gems' >> ~/.bashrc
echo 'export PATH=$HOME/gems/bin:$PATH' >> ~/.bashrc
source ~/.bashrc
gem install jekyll bundler

change the gem source:

gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/

Build Site

# After you install jekyll
jekyll new ~/username.github.io/

After you do this, you will see a directory blog, then:

cd username.github.io
jekyll server

Then your site could be seen at: http://localhost:4000, open your browser and type it, you'll see your new site.

# build site in local
bundle exec jekyll build
bundle exec jekyll server --incremental

Blog Directory Structure

If you ls in your blog directory, you will see many files, an overview of what will be used for you does:

_config.yml: your configuration data

In this file, you could do many things to your site, this is my _confg.yml file, you can edit as soon as you like.

#_config.yml
title: Nerche Note
email: weigao1024@foxmail.com
description: > # this means to ignore newlines until "baseurl:"
  Welcome to my profile pages!
baseurl: "" # the subpath of your site, e.g. /blog
url: "" # the base hostname & protocol for your site
github_username:  chenweigao

_posts: this is where your article stored, when you want to publish a new blog, to CREATE a new file here, the naming convention of these files is important, and must follow the format:YEAR-MONTH-DAY-title.md, such as: 2018-02-02-myblog.md, please remember this, it is very important.

Add Post

We create a new markdown file named 2018-02-02-test.md:

---
layout: article
title:  "This is a test blog"
tag:
  - blog
modify_date: 2017-01-01
---
## You will see me at [https://localhost:4000](https://localhost:4000)
The head is **required** in every post
which tells the system your post's title, layout, time and so on...

Then you need to open your terminal, and type:

jekyll build
jekyll server

Then you open your browser, and type https://localhost:4000 ,you will find the blog's update.

Publish Blog

Now it is time to publish your blog in GitHub Pages, you need to:

git add .
git commit -m "my frist blog"
git push

Then you can see your blog at username.github.io, such as chenweigao.github.io

Highlight Code

Sometimes, especially for a coder, you may want to highlight your code:

{% raw %}
{% highlight c linonos %}

int mian(){
  printf("Hello Jekyll!\n");
  return 0;
}

{% endhighlight %}
{% endraw %}

提示

raw and endraw make the code not parsed by Jekyll.

Including Images and resources

Chance are, at some points, you'll want to include images, downloads, or other digital assets along with your text content. There are a number of ways to include digital assets in Jekyll, one common solution is to create a folder in the root of the project directory call something like assets, into which any images, files or other resources are placed.

Including an image assets in a post:

![My helpful screenshot]({{ site.url }}/assets/screenshot.jpg)

or:

![My helpful screenshot]({{ "/assets/screenshot.jpg" | absolute_url }})

linking to a PDF for readers to download:

[get the PDF]({{ site.url }}/assets/mydoc.pdf)

see at the official guide,Writing Post.

Add HTTPS

When you want to add HTTPS, it is really a big work, see this guide, that is helpful. The tool we use is cloudflare.

There is an auto tool can help you add https, Netlify, which helps you set your site here, and make it faster, more importantly, it is free, highly recommend.

highlight.js

using highlight.js, downloads the package and select a .css, then in header.html:

<link rel="stylesheet" href="{{ site.url }}/assets/css/default.css">
<script src="{{ site.url }}/assets/css/highlight.pack.js"></script>
<script>hljs.initHighlightingOnLoad();</script>
