Publishing your Emacs configuration with Jekyll

Share:

Many people in the Emacs community use orgmode. Quite a few of them use the org-babel system to write and maintain their emacs configuration, and so am I. I find the biggest advantage to be able to document my thought process as well as the configuration details. Emacs configuration can get pretty big and maintaining it becomes a lot easier for me if I can read back what I was thinking 6 months ago.

The system borrows from literate programming concepts where you write code and documentation in one document and let tools tangle the code and documentation into separate documents.

{%pullquote right %} The default way to publish an Emacs configuration with that system would be to let org-mode export the configuration document to html and publish that somewhere. What I wanted to do was to use the in-place org-mode converter I am using with Jekyll. In short, {"the ideal would be that jekyll fetches the authoritative version of my emacs configuration in org-mode syntax"} and treats that as normal content and publish it. {% endpullquote %}

I started off by defining a collection, a new feature of jekyll, which gave me a chance to use it. The collection is defined in the _config.yml file:

1  # Emacs collection contains emacs 'generated' documents
2  collections:
3    emacs:
4      # Render them, i.e. convert them to html. 
5      output: true

This will render source files in the _emacs folder as if they were pages. The url generated for them will be prefixed by /emacs/.

In this folder I placed a file config.org with the following contents

1---
2layout: orgmode
3--- 
4
5[... text left out  ..]
6
7{% raw %}
8{% include extern/mrb.org %}
9{% endraw %}

That includes the file <root>/_includes/extern/mrb.org from the jekyll installation and renders its content. The only correction I had to make was to insert a raw...endraw block around some org-mode settings.

You can view the result of the rendering in /emacs/config/
