hakyll-contrib- Extra modules for the hakyll website compiler



This module provides a simple default configuration which behaves similar to a tool such as the Jekyll static site generator (http://jekyllrb.com/).

The idea is that you don't have to write your configuration yourself: you just follow some conventions, and Hakyll does the rest.

You can generate a site which will serve as a good starting point by running the command-line tool:

 hakyll-contrib small-blog

Hakyll will then generate a simple example site for you. The necessary configuration is placed in the hakyll.hs file. Compile and run it to create the demo site:

 ghc --make hakyll.hs
 ./hakyll build
 ./hakyll preview

So, in order to get your site going, you need to follow the conventions for the content on your site.

Images should be placed in the images/ or img/ folder. The are copied directly. Other static files (but not images) can be placed in static/ or files/. The favicon.ico file is an exception, it is just placed in the top-level directory.

CSS files should be placed in css/, and JavaScript files in js/.

Then, we arrive at pages. You can create any number of pages on your site: just create files in one of the documents pandoc supports (.html, .markdown, .rst, .lhs...) in the top-level directory.

These pages may use a number of preconfigured $key$'s:

  • $recentPosts$: A list of recent posts, displayed from most recent to oldest. By default, 3 posts are shown, altough this can be configured using the numberOfRecentPosts field.
  • $allPosts$: A list of all posts, displayed from most recent to oldest. This is very useful for creating an archive page.
  • $chronologicalPosts$: Similar to $allPosts$, but displays the posts in chronological order.

For example usage, look at the example site we generated using hakyll-contrib small-blog.

Now, one can wonder where these posts come from. Simple: all pages in the posts/ directory are considered posts. Note that a naming format of


is mandatory. An example:


This allows Hakyll to parse the date easily, among other things. Again, look at the example site for some example posts.

Additionaly, there is the templates/ folder. This folder holds the templates for your site. For a small-blog configuration, your site should have exactly three templates:

  • templates/default.html: The main template. This should contain your HTML doctype, head, etc.
  • templates/post.html: A template which is applied to every post before it is rendered using the default template.
  • templates/post-item.html: A template which is applied to posts in listings (e.g. $chronologicalPosts$).

Again, the example should clarify things.

This configuration should be enough to create a small personal website. But, we have only touched the surface of what is possible with Hakyll. For more information, check out the tutorials at: http://jaspervdj.be/hakyll
