I assume that you are familiar with HTML, the bash command line, and that you are comfortable using Markdown to format content. I’ll explain how Hugo uses templates and how you can organize your templates to create a theme. I won’t cover using CSS to style your theme. We’ll start with creating a new site with a very basic template. /post/goisforlovers/ Wed, 02 Apr 2014 00:00:00 +0000 /post/goisforlovers/ Hugo uses the excellent go html/template library for its template engine. It is an extremely lightweight engine that provides a very small amount of logic. In our experience that it is just the right amount of logic to be able to create a good static website. If you have used other template systems from different languages or frameworks you will find a lot of similarities in go templates. This document is a brief primer on using go templates. /post/hugoisforlovers/ Wed, 02 Apr 2014 00:00:00 +0000 /post/hugoisforlovers/ Step 1. Install Hugo Goto hugo releases and download the appropriate version for your os and architecture. Save it somewhere specific as we will be using it in the next step. More complete instructions are available at installing hugo Step 2. Build the Docs Hugo has its own example site which happens to also be the documentation site you are reading right now. Follow the following steps: Clone the hugo repository Go into the repo Run hugo in server mode and build the docs Open your browser to http://localhost:1313 Corresponding pseudo commands: /post/migrate-from-jekyll/ Mon, 10 Mar 2014 00:00:00 +0000 /post/migrate-from-jekyll/ Move static content to static Jekyll has a rule that any directory not starting with _ will be copied as-is to the _site output. Hugo keeps all static content under static. You should therefore move it all there. With Jekyll, something that looked like ▾ <root>/ ▾ images/ logo.png should become ▾ <root>/ ▾ static/ ▾ images/ logo.png Additionally, you’ll want any files that should reside at the root (such as CNAME) to be moved to static. /about/ Mon, 01 Jan 0001 00:00:00 +0000 /about/ Hugo is a fast and modern static site generator written in Go, and designed to make website creation fun again. Hugo is a general-purpose website framework. Technically speaking, Hugo is a static site generator. Unlike systems that dynamically build a page with each visitor request, Hugo builds pages when you create or update your content. Since websites are viewed far more often than they are edited, Hugo is designed to provide an optimal viewing experience for your website’s end users and an ideal writing experience for website authors.
