How to setup a search feature in your Jekyll static site

I found Jekyll recently, and decided to give it a go. I already have my blog set up freely at wordpress but I’ve always looked for a way to manage the several notes and links and what nots in a way they are easily accessible.

Jekyll provides me with a simple and accessible way to do so, i can host them up at GitHub pages or just run them locally.

If you don’t know what Jekyll is go check out their website, but i’ll pull a simple description from the docs here:

It takes a template directory containing raw text files in various formats, runs it through Markdown (or Textile) and Liquid converters, and spits out a complete, ready-to-publish static website suitable for serving with your favorite web server. Jekyll also happens to be the engine behind GitHub Pages, which means you can use Jekyll to host your project’s page, blog, or website from GitHub’s servers for free.

Now for my use, i need to make sure i could search the site. But since Jekyll only serves static pages, there is no way to any server side magic.

Enter Tipue Search a jquery based search engine. This is pretty cool and it has a bunch of features.

In Jekyll we will be using Tipue Search in static mode, it basically reads a javascript file and displays the results based on the JSON object present.

I won’t get into how to set up Tipue Search, read their docs or the bazillion articles written on the web about it. It’s pretty straight forward.

After everything was setup there was the problem of feeding the tipue_content.js file (used by the engine to show the results page).

Jekyll is plugin friendly so we can create plugins to expand Jekyll to our own needs, basically when you build your site Jekyll automatically runs all plugins in the _plugins folder.

This happens before serving the static files. So we can create a plugin to generate our tipue_content.js file based on our _posts folder.

One type of plugins you can create are Generators, these allow us to generate content based on our site structure and information.

You can find my Tipue Search Generator here. To use it just put the file in your _plugins folder and rebuild your site. Notice that GitHub Pages are run in safe mode, so the plugins will not be executed. You need to build the site locally before committing the tipue_content.js file up to GitHub Pages.

To use this make sure to put the following tags in your post YAML:

* tags – space separated list of tags for a given post
* tipue_description – The searchable text for that post. Also shown on the search results page.

This generator does not use the post content itself, it uses the content for the YAML tag tipue_description. It is technically possible to use your entire post content as a searchable text, i decided against this since The post it self might be quite big or have a ton of stuff that shouldn’t be imported (images, links, etc) that i would need to cut out before generating the text.

I’d like to thank Dave Perrett since his Category Page Generator was really helpful in creating the tipue content generator.

Kill Messages on Ruby applications

January 9, 2009 Leave a comment

Trying to get into ruby and i ran in to a somewhat important requirement. I need to know when my app is closing, wether it was me that shut it down or the OS just simply sent it a kill message. So i did some digging, made a fool of my self by posting to comp.lang.ruby and later on found the solution. Directly from the ruby documentation:

at_exit { block } → proc

Converts block to a Proc object (and therefore binds it at the point of call) and registers it for execution when the program exits. If multiple handlers are registered, they are executed in reverse order of registration.

   def do_at_exit(str1)
     at_exit { print str1 }
   at_exit { puts "cruel world" }
   do_at_exit("goodbye ")


   goodbye cruel world
