Gakubuchi

Gem Version Build Status Code Climate Test Coverage

Gakubuchi provides a simple way to manage static pages (e.g. error pages) with Asset Pipeline.

Installation

Put this in your Gemfile:

gem 'gakubuchi'

Run the installation generator with:

rails g gakubuchi:install

Or specify the name of directory for static pages:

rails g gakubuchi:install -d html

They will install the initializer into config/initializers/gakubuchi.rb and create the directory in app/assets.
If you don't specify the -d option, templates will be used as default.

Usage

In app/assets/templates/404.html.slim:

doctype html
html
  head
    title The page you were looking for doesn't exist (404)
    meta name='viewport' content='width=device-width,initial-scale=1'
    = stylesheet_link_tag 'application', media: 'all'
  body
    .dialog
      div
        h1 The page you were looking for doesn't exist.
        p You may have mistyped the address or the page may have moved.
      p If you are the application owner check the logs for more information.

Open the following URL in your browser to check the templeate:

http://localhost:3000/assets/404.html

Compile the templeate with:

rails assets:precompile

This will generate public/404.html.

Template engines

Gakubuchi supports some template engines: ERB, Haml and Slim.
When you want to use Haml or Slim, you need to put them in your Gemfile:

# Use Haml
gem 'haml'

# Use Slim
gem 'slim'

Using assets

Gakubuchi enables you to use assets (e.g. CSS or JavaScript files) in static pages.
Note that you may need to add them to the precompile array in config/initializers/assets.rb:

Rails.application.config.assets.precompile += %w(error.css error.js)

Using helpers

You can also use helpers provided by Sprockets::Rails::Helper in static pages.
Examples of them are given below.

  • asset_path
  • content_tag
  • favicon_link_tag
  • image_tag
  • javascript_include_tag

If you want to get the list of all available helpers, please execute the following code.

Sprockets::Rails::Helper.instance_methods

Configuration

In config/initializers/gakubuchi.rb, you can configure the following values.

leave_digest_named_templates # false by default
template_directory           # 'templates' by default
