Blogging with Emacs and Org Mode

Table of Contents

1 Overview

So you ar wondering if Emacs1 can be used to do blogging and at the same time also thinking about why use Org Mode2? Well the answer is simple. I want to keep things simple. Blogging is all about content and I spend lot of time making notes, keeping a list of things I want to do in Org Mode, there are lot of blog I just couldn't write on my Drupal site www.ravisagar.in because it is a bit of a pain to copy, organise and transfer it to a web portal.

With Emacs and Org mode you can just do blogging from your terminal (yes I used Emacs in terminal mode) and I believe I can do it much faster and will be able to share more information quickly whenever I want. Also the other benefit is that with Org mode I can share code snippets that can also be run and evaluated. It is so much fun :)

2 Who this blog is for?

  • You use Emacs
  • You use Org mode
  • You want to blog
  • You want to share content with code
  • You like simplicity

3 This blog/site is built with Emacs and Org Mode

I made this site using Emacs of course (otherwise what is the point). Apart from my Drupal sites I have tried using Hugo, Grav, Github pages before, I still have those blogs up and running but I don't plan to update it with more content. Those static site generator where more of an experiment. I personally loved working on Hugo for its simplicity and I was amazed by Grav for its CMS like capabilities (it is still file based).

12 Publish a website

So are you ready to launch a website using Org mode? Great. Let us begin. First you need to modify your Emacs configuration file - .emacs for publishing to work.

12.1 Snippet of my .emacs file responsible for publishing this blog

The following code make sure that it will read the *.org files in a specific directory and it will generate HTML out of it and also add few other things like header, footer and css.

12.1.1 TODO So let us discuss this piece of code

12.2 Publishing commands

These commands will be used to publish the site into HTML format to a specific location that you set above in the .emacs file.

  • Publish: M-x org-publish
  • Shortcut: C-c C-e P x PROJECTNAME
  • Force publish (all files): C-u M-x org-publish

12.2.1 Issues you may encounter

  • Sitemap title not updating?: Clear the content of ~/.org-timestamps folder and export again.

12.3 CSS used on my site

body{

    max-width: 70%;
    margin: auto;
    font-family: "Open Sans", "Helvetica Neue", Helvetica, Arial, sans-serif;
    color: #222222;

}
.nav {
    background: #aeaeae;
    padding: 10px;
}
.preamble {
    background: #330000;
    padding: 10px;
    color: #ffffff;
}

.preamble a:visited {
    color: #ffffff;
}

.preamble a:link {
    color: #ffffff;
}

12.4 TODO Host your website

I use GitLab.com to host my site. I manage the directory where I publish my HTML in my Git repository on GitLab.

I also made a video about it.

13 Execute code - Literate Programming

You can insert code snippets in your document.

  • C-c C-c – Execute the code

When you export to HTML you will be asked to export all the code blocks one by one. However you can execute them without your confirmation.

Two ways to do it.

  1. Set this in your .emacs file.
(setq org-confirm-babel-evaluate nil)
  1. Add this on top of your file, close and open the file again.
# -*- org-confirm-babel-evaluate: nil -*-

14 Open a website in Emacs

Emacs Web Wowser - eww can be used to open sites.

  • M-x-eww then type in the url.
