I have been using Wordpress for few years now and have been very happy with its features. In the past year, I have tried several times to change the theme on my blog and also semantify my posts by using Markdown as my de facto style. Of course, none of it happened and I was still using a combination of HTML and Rich Text Editor for formatting my posts.The more I delayed, the more I realized that there were a lot more reasons to NOT like Wordpress:
I had seen a few bloggers use GitHub as their blogging engine with the Jekyll framework to auto-generate their HTML pages from their markdown posts. This was very inviting except for the fact that I had to store all my posts publicly on Github. Even if I purchased a private plan from Github, the storage allocated was quite minimal. GitHub for me was definitely not cost effective.
About this time, I saw a tweet from Matt Gemmell where he migrated from Wordpress to a different engine called Octopress. After reading his blog entry, I realized this was exactly the kind of framework I wanted. Matt has lot more content than I do and seeing him convert his blog successfully gave me the courage to do the same. Thus began an almost 10 day journey to convert my Wordpress blog to an Octopress blog!
There are many things to like about Octopress:
rake previewcommand that starts up a local web server. It monitors changes to my blog and auto generates the html. This is great for composing posts and testing on the fly.
This was the most elaborate part of the process. Octopress requires that you do write all your posts in Markdown or Textile, however my Wordpress posts were all plain html. So I needed some converter that would do this transformation for me. Luckily on Matt’s blog I read about the exitWP plugin that takes care of this conversion. Although not seamless, exitWP did give me a good starting ground since it converts all the posts to a Jekyll-compliant site.
I did have to go in and change several of my posts that used code snippets. I had been using a variety of code prettifiers over the years and the corresponding HTML was not the best for a Markdown conversion. It did mess up lot of my posts and I spent several hours touching up the Markdown text.
I also got the chance to fix some of my old Urls that were still pointing to my old blog on Live Spaces. I also decided to make all my internal blog links relative and this required a combination of grep/awk and some manual intervention to fix up all the links. Overall it was a fun exercise experimenting with some bash shell commands and a mix of some ruby scripting.
Octopress has excellent integration with Disqus, a hosted comment management system. Disqus works by linking all the comments to a specific Url. As long as your posts maintain the same Url you can just use Disqus to import all of your comments into your octopress blog. In my case, my comments were all on Wordpress and I had to first import them into Disqus. As it turns out, this wasn’t a straightforward process.
I started by exporting my comments from Wordpress in the standard WXR Xml format. When I tried to import this file into Disqus, it choked by complaining that the
<link> tags were missing. The
<link> tag contains the url that links the post to the comments. To fix that I wrote some simple ruby code to update the WXR with the proper
<link> tags. Now trying the import again inside Disqus went through without issues and all my comment threads got pulled in. The threads however were using the raw wordpress url (http://blog.pixelingene.com/?p=123) and I wanted to use a more semantic url of the form http://blog.pixelingene.com/year/month/the-post-slug. To fix this I created a simple Url map (CSV) and used the Disqus Url Mapping Tool to fix these links.
Finally with all that done, my comments were safe and sound inside Disqus, with the right permalink-Urls. Now the next part was to link them up with my blog. Luckily this is as simple as specifying a
disqus_short_name in the Octopress config file!
Now that I had chosen to use a semantic permalink to my posts, I also had to make sure my existing links to the posts continued working. This was a matter to having some redirects set up on my website. I used the standard Apache directives (
RewriteRule) in my
.htaccess to permanently redirect all of my old urls.
A few other things I had to do include:
The one thing I havent’ done yet is modify the theme from the default. I’ll probably get to it one of these days.
So that’s my experience with the Wordpress to Octopress migration. Although not a smooth transition, it wasn’t terribly bad and I actually enjoyed the process using a variety of tools. I have tried my best to make sure that all existing wordpress links, images, download links, demos, etc. continue working, but there is always that infinitesimal probability of missing something. If something does break, I’ll find out in one way or other. Until then “enjoy the new blog!”
