A Ruby minimalistic filesystem based blog engine made for developers.
Different from other blog engines, rollin only does what matters, and leave the rest to you.
It currently supports Markdown format and uses the Github's awesome redcarpet.
Add the dependency to your Gemfile:
gem 'rollin'
First you will need to have the following structure in your filesystem.
├── posts
└── 2013_05_01_My_first_post.md
blog = Rollin::Blog.new({articles_folder: "posts"}) # Defaults to "articles"
article = blog.articles.first
article.id # => "2013_05_01_My_first_post"
article.title # => "My first post"
article.body # => "<h3>My first post!</h3>\n<p>blah blah blah</p>"
article.date # => #<Date: 2013-05-01 ((2456414j,0s,0n),+0s,2299161j)>
article.year # => 2013
article.month # => 05
article.day # => 01
You may define articles metatags at the beginning of your article with the format:
---
author: Zé
title: My new awesome blog!
tags: development, fun
---
This is how you access the tag information.
article.metatags # => { 'title' => 'My new awesome blog!',
'author' => 'Zé',
'tags' => [ 'development', 'fun' ] }
It is YAML snippet and follows a similar format to Jekyll's yaml front matter. Except that our special variables are different:
| Metatag | Description |
|---|---|
| title | The article title. It overrides the extracted title from the file name. |
| published | If the article is published. Defaults to "yes". Set it to "no" or "false" to hide an article. |
blog.metatags # => A list of metatag objects
author_metatag = blog.metatags.first
author_metatag.label # => "tags"
author_metatag.values # => A list of metatag value objects
author_metatag_value = metatag.values.fist
author_metatag_value.content # => "Zé"
author_metatag_value.articles # => A list of articles containing that metatag value
blog.article('2013_05_01_My_first_post') # => #Rollin::Article(:title => "My first post" ...)
blog.articles(:tags => "development") # => A list of articles tagged with development
blog.articles(:year => 2013) # => A list of articles for that year
blog.articles(:year => 2013, :month => 5) # => A list of articles for that month
blog.articles(:year => 2013, :month => 5, :day => 1) # => A list of articles for that day
may_archive = blog.monthly_archive.first
may_archive.year # => 2013
may_archive.month # => 5
may_archive.articles # => [ Rollin::Article(:title => "My first post" ...) ]
twenty_thirteen_archive = blog.annual_archive.first
twenty_thirteen_archive.year # => 2013
twenty_thirteen_archive.articles # => [ Rollin::Article(:title => "My first post" ...) ]
twenty_thirteen_archive.monthly_archive # => [ Rollin::MonthArchive(:year => 2013, :month => 5 ...) ]
You can find a more detailed documentation at the rollin_spec.rb file.
Since it is meant to be used in a blogging domain it is not optimized with caching. You should implement cache in the infrastructure layer, what shouldn't be hard in a mostly static environment.
