Kagami

Simple and clean theme for Jekyll and GitHub Pages.

Add this line to your Jekyll site's Gemfile:

gem "jekyll-theme-kagami"

And add this line to your Jekyll site's _config.yml:

theme: jekyll-theme-kagami

And then execute:

$ bundle

Or install it yourself as:

$ gem install jekyll-theme-kagami

Jekyll build is integrated with GitHub Pages with limited function. This section is intended for those who want to use the theme with GitHub Pages hosted sites.

1. Download latest gem file from https://rubygems.org/gems/jekyll-theme-kagami
2. Run gem unpack [path-to-downloaded-gem-file] --target=. on jekyll site project folder
3. Delete the line theme: ... in _config.yml

Zip archive downloaded from release page may not work because GitHub does not pack necessary files from submodules.

Instruction 1 and 2 can also work when you decide to upgrade your installation.

You can customize social account links by adding following lines to _config.yml

github_username: my_github_username
twitter_username: my_twitter_username
instagram_username: my_instagram_username

You can customize footer by overriding _includes/footer.html.

Kagami support color schemes from jekyll-pygments-themes.

Add the following lines to choose a color scheme:

color_scheme: github

Add the following lines to your Jekyll site to enable Disqus comment service:

disqus_shortname: my_disqus_shortname

You can find out more about Disqus' shortnames here.

For Gitalk:

gitalk:
  id: <clientID>
  secret: <clientSecret>
  repo: <repo>
  owner: <owner> # (optional) if not set, value of `github_username` will be used
  admin: <admin> # (optional) if not set, value of `github_username` will be used
  proxy: ...     # (optional)

By default, comment service will only be enabled in production mode, set an environment JEKYLL_ENV=production for local test.

If you don't want to comments for particular posts you can disable that by adding comments: false to the post's YAML Front Matter.

To enable Google Anaytics, add the following lines to your Jekyll site:

google_analytics: UA-NNNNNNNN-N

Google Analytics will only appear in production, i.e., JEKYLL_ENV=production

Pages and posts can be registered as navigation item with following frontmatter:

navbar_title: Awesome Title # specifies the text to display as navigation item

Navigation items are ordered in alphabetical order by default in Jekyll. Adjust the order manually with a position value:

position: 999

Layout file post-list supports filtering by tag or category. Create pages with following frontmatter will generate a filtered post list.

title: Title of Tag Page
layout: post-list
filter:
  - by_tag: tagname

To filter by both category and tags:

filter:
  - by_tag: tagname
    by_category: category

Results from multiple filters are combined (logical 'or') into the result.

A more flexible filter strategy is supported by supplying liquid expression to by_expression parameter in which post object can be referenced by the name post.

You can use MathJax with Kramdown's built-in support.

To enable MathJax, add following lines to your site or post's front matter stuff:

mathjax: true

To enable mermaid, add following line to the site configuration or post's front matter stuff:

mermaid: true

Code blocks with mermaid language tag should be transformed into diagrams.

Taking advantages of Block/span IAL, Kagami supports extra elements in writing.

Add {:.side-note} notation after a paragraph (in a new line just after paragraph WITHOUT extra line breaks) will style the paragraph as a sidenote. Sidenote will be pull to the left of the page and only be visible in desktop mode.

Kagami is also optimized for high-res image display:

![image@2x](path-to-image@2x.png){:.retina2x}

And the retina image will be scaled to half of it's original size in pixels.

To set up your environment to develop this theme, run bundle install.

Your theme is setup just like a normal Jekyll site! To test your theme, run bundle exec jekyll serve -s example and open your browser at http://localhost:4000. This starts a Jekyll server using your theme. Add pages, documents, data, etc. like normal to test your theme's contents. As you make modifications to your theme and to your content, your site will regenerate and you should see the changes in the browser after a refresh, just like normal.

When your theme is released, only the files in _layouts, _includes, and _sass tracked with Git will be released.

The theme is available as open source under the terms of the MIT License.
