Aug 8, 2021 | Programming

Welcome to the world of Cryogen! This blog will guide you through the process of setting up your very own blog using Cryogen, a static site generator built for Clojure. With features like Markdown support, code syntax highlighting, and Disqus integration, you’ll soon have a professional-looking blog at your fingertips. Let’s dive in!

Features of Cryogen

  • Blog posts and pages styled with Markdown or AsciiDoc
  • Tag management
  • Automatic table of contents generation
  • Configurability with plain HTML templates
  • Syntax highlighting for code snippets
  • Support for Disqus comments
  • Efficient sitemap and RSS feed generation
  • Pre-compilation support with Sass or SCSS
  • Klipse integration for interactive code samples

Getting Started with Cryogen

Creating a New Site

To create a new blog site, you can opt for one of the following tools: Leiningen, clj-new, or deps-new.

Creating a New Site with Leiningen

First, ensure you have Leiningen version 2.5.0 or above installed. Then run the following command to start your new site:
lein new cryogen my-blog

Creating a New Site with clj-new

Alternatively, you can use clj-new:
clojure -Ttools install com.github.seancorfield/clj-new :gittag v1.2.362 :as clj-new
clojure -Tclj-new create :template cryogen :name my-name-my-blog :force true
cd my-name-my-blog

Creating a New Site with deps-new

Another option is to use deps-new:
clojure -Ttools install io.github.seancorfield/deps-new :gittag v0.4.0 :as new
clojure -Sdeps '{:deps {io.github.cryogen-project/cryogen {:gittag "0.6.6" :gitsha "fcb2833"}}}' -Tnew create :template org.cryogenweb/new :name my-name-my-blog
cd my-name-my-blog

Running Your Blog

Once your site is created, start the web server using one of the following commands:
lein serve
# or for faster compilation
lein serve:fast
# or using tools-deps
clojure -X:serve
# or for faster compilation
clojure -X:serve:fast
The server will automatically watch for changes. It’s like having a personal assistant that quickly makes the necessary adjustments to your blog every time you make a change.

Site Configuration

Your blog’s configuration can be modified in the `content/config.edn` file. This file controls various settings such as site title, author name, and post layout. Here’s a snippet of what it might look like:
:site-title                   "My Awesome Blog"
:author                       "Bob Bobbert"
:description                  "This blog is awesome"
:site-url                     "http://blogawesome.com"
:post-root                    "posts"

Switching Between Markdown and AsciiDoc

Cryogen defaults to Markdown. If you wish to switch to AsciiDoc, modify the `project.clj` file to use `cryogen-asciidoc` and change the input files accordingly.

Selecting and Customizing Themes

Themes can be easily changed by editing the `config.edn` file. Cryogen comes with several built-in themes, and you can explore more by visiting this site.

Troubleshooting

Even with a carefully crafted setup, issues may arise. Here are some troubleshooting tips:
  • If your site doesn’t display as expected, ensure all dependencies in your project files are correct and up to date.
  • Check server logs for errors during the build process.
  • Consider cleaning your cache or rebuilding your project if changes do not appear.
  • If issues persist, visit the Cryogen documentation for further assistance.

Deploying Your Site

The generated static content can be found in the `public` folder. You can deploy your site using a server like Nginx or Apache. Here is an example Nginx configuration:
server {
    listen 80 default_server;
    server_name localhost yoursite.com www.yoursite.com;
    location / {
        alias /var/blog;
        error_page 404 = 404.html;
    }
}
This setup directs requests to the correct directory, ensuring your blog is served correctly.
