Blogue

Blogue is a rails model for static blog posts, wrapped in an engine. It means that you can have blog posts as static files (kind of like views) inside your rails app, and hook up posts like any other resource. The only reason this is an engine and not just a class in a gem is because it also adds an asset path and a handler for .md views.

Check out my blogue article for some fun stuff it can do: http://hakunin.com/blogue

What you get

A Blogue::Post model
Handler for ".md" views (kramdown by default)
Syntax highlighting for code blocks (rouge by default)

What you don't get

Mountable endpoint
Default controllers
Default views
Generators
Comments, tags or pretty much any functionality

There are thousands of gems that you can pick from to do that stuff.

Usage

Generate a rails app (or use existing)

Add all needed gems to Gemfile and bundle

gem 'kramdown'
gem 'rouge', '~> 1.11.1' # 2.x and newer is not supported yet
gem 'blogue'

Create a model app/models/post.rb (the name 'Post' is chosen at random)

class Post < Blogue::Post
  # Here you can override inherited methods any way you like.
  # See app/models/blogue/post.rb to see what you have
end

Create a controller app/controllers/posts_controller.rb

class PostsController < ApplicationController
  def index
    @posts = Post.all
  end

  def show
    @post = Post.find(params[:id]) ||
      raise(ActionController::RoutingError.new('Not Found'))
  end
end

Add a route to your config/routes.rb like this

root to: 'posts#index' # if you want an index page
get '/:id', to: 'posts#show'

Add app/views/posts/index.html.erb for your index page

<% @posts.each do |post| %>
<p>
  <%= link_to post.title, post.id %>

  <% if post.tldr %>
  <blockquote>
    <%= post.tldr %>
  </blockquote>
  <% end %>
</p>
<% end %>

Add app/views/posts/show.html.erb for your post page

<%= link_to 'index', root_path %>

<%=raw render file: @post.path %>

<% if @post.date %>
<p>Published on <%= @post.date.to_s(:long) %></p>
<% end %>

Create a directory app/posts (that's default location of posts)
Create a directory app/posts/assets (it's added to assets paths by default)

Add a post like app/posts/my-first-post.md

# Yay my first post

This is some text.
