A few months back I switched this blog to Jekyll. Jekyll is a static blog generator; it transforms a directory of input files into another directory of files suitable for a blog. The management of the blog is handled by standard, familiar tools like creating and renaming files, the text editor of your choice, and version control. Jekyll combined with Git and Emacs has made blogging feel very natural to me.
What is WordPress, Really?
WordPress and other blogging systems are simplified content management systems. Many of the features they provide relate to a blog's minimal need for dynamic content. The front page needs to change as new things are added, and each post must change as comments, trackbacks, and edits are made.
Along they way they often made it harder to just write. While they keep providing more and more sophisticated text editing capabilities, most of us who write or code are quite comfortable in our own editors. No matter how good the text editing widgets become, they are not Emacs or vim or TextMate.
Blogs have simple APIs for using external products, but even these products are often not great text editors. When the real text editors have added the ability to speak these APIs, the functionality feels bolted on and clunky. The reason is that we are used to interacting with documents in a file system, and the current blogging APIs are much less elegant than the familiar, simple API of a file system.
Managing documents is something nearly everyone using a computer has
gotten quite good at, and the tool support for this is immense. We
have automatic indexing systems like Spotlight, powerful search tools
grep, and history tracking and analysis tools like
WordPress and others would do well to concentrate on the areas where blogging software is really needed and expose the document management part via WebDAV or something similar. In the end, WordPress is a transformation layer to take some set of documents and turn it into a blog as well as a system to provide commenting, trackbacks, and search.
The Post-WordPress World
Let's look at the key areas where blogging software is necessary. We have transformation of content, interaction with content (commenting and such features), and search. In all these areas superior, domain specific tools have emerged.
Search is dominated by Google, but there are other services that can also be used. I have been really underwhelmed by the search capabilities found in self-hosted blogs, but Google's site search is really good.
Interaction services started appearing as spam became a problem for blog comments. Now we have full featured services like IntenseDebate and Disqus which provide excellent interaction features like email integration, comment aggregation, moderation and filtering, and portable identity.
Now we come to transformation of content, which turns out to be the only missing piece that on really needs.
Jekyll Generates Blogs
Jekyll fills this last piece of the blogging feature puzzle. It takes a tree of documents and transforms that into a blog.
At a basic level, Jekyll goes through the directory tree and translates files from a variety of formats like Markdown and Textile into HTML. Each file can contain a small YAML header with metadata. These metadata blocks tell Jekyll which template to use during rendering and define the title and other properties of the document.
A few directories in Jekyll are special.
_posts contains all the
blog posts, with each post being named in a common format such as
contains documents that are ignored by Jekyll.
rendering templates that are used during the transformation process.
My own templates use Disqus for comments and Google for search, but it is easy to mix and match the services you want in your own templates.
The resulting generated site has a standard URL structure of
/2009/01/14/blogging-with-git-emacs-and-jekyll/ and the front page
and RSS or Atom feeds are just simple templates that loop over the
latest group of posts.
Managing and Publishing with Jekyll
You can use Jekyll by hand, but it is meant to be used alongside a
version control system. Whenever you commit or push to the
repository, it runs the
jekyll command to generate the blog from the
Git is a popular choice here, but Subversion or Bazaar would also do a fine job. One thing I like about Git is that I can set up a remote on my main machine to my Eee laptop, and a corresponding remote in the other direction. Both machines have the origin remote set to my blog's server. This means I can easily push and pull the blog around between machines and I always have access to the entire blog no matter what machine I'm on.
I also wrote some Emacs
glue to help
automate my own blogging workflow. I start new drafts with
C-c b n
and then move drafts to the
_posts folder with
C-c b P. I can
also easily access the list of drafts or posts when I'm searching for
something I've previously written. This kind of glue is easy to write
in any language because it leverages the familiar platform of the file
Why I Love This System
Now that I've been using this system for several weeks, I'm really loving it.
- I'm using the same tools I always use for the rest of my work to write and manage my writing.
- I always have access to my entire blog, which is awesome when I am crafting posts on plane rides and need to reference some previous content.
- If I find some manual thing in my workflow, I can use any number of common tools to automate or customize it. Everything is just text and files.
- Comments are now just email threads to me, which means I don't have to use some clunky interface. Once again, I can use tools which are already part of my daily work habits.
If you've ever thought about blogging, or blogging more, but didn't want to mess around with blogging clients, Web interfaces, or installing or maintaining blogging software, you should give Jekyll a try.
