Stasis

Stasis is a dynamic framework for static sites.

Install

Install via RubyGems:

$ gem install stasis

Example

At its most essential, Stasis takes a directory tree with supported template files and renders them.

Example directory structure:

project/
    index.html.haml
    images/
        image.png

Run stasis:

$ cd project
$ stasis

Stasis creates a public directory:

project/
    index.html.haml
    images/
        image.png
    public/
        index.html
        images/
            image.png

index.html.haml becomes public/index.html.

Unrecognized extensions are copied as-is (image.png).

Controllers

Controllers contain Ruby code that executes once before all templates render.

Example directory structure:

project/
    controller.rb
    index.html.haml
    styles/
        controller.rb
        style.css.sass

You may have a controller at any directory level.

Before

Use before blocks within controller.rb to execute code before a template renders.

controller.rb:

before 'index.html.haml' do
  @something = true
end

@something is now available to the index.html.haml template.

The before method can take any number of paths and/or regular expressions:

before 'index.html.haml', /.*html\.erb/ do
  @something = true
end

Layouts

layout.html.haml:

%html
  %body= yield

In controller.rb, set the default layout:

layout 'layout.html.haml'

Set the layout for a particular template:

layout 'index.html.haml' => 'layout.html.haml'

Use a regular expression:

layout /.*html.haml/ => 'layout.html.haml'

Set the layout from a before block:

before 'index.html.haml' do
  layout 'layout.html.haml'
end

Render

Within a template:

%html
  %body= render '_partial.html.haml'

Within a before block:

before 'index.html.haml' do
  @partial = render '_partial.html.haml'
end

Text:

render :text => 'Hello'

Local variables:

render 'index.html.haml', :locals => { :x => true }

Include a block for the template to yield to:

render 'index.html.haml' { 'Hello' }

Instead

The instead method changes the output of the template being rendered:

before 'index.html.haml' do
  instead render('subdirectory/index.html.haml')
end

Helpers

controller.rb:

helpers do
  def say_hello
    'Hello'
  end
end

The say_hello method is now available to all before blocks and templates.

Ignore

Use the ignore method in controller.rb to ignore certain paths.

Ignore filenames with an underscore at the beginning:

ignore /\/_.*/

Priority

Use the priority method in controller.rb to change the file process order.

Copy .txt files before rendering the index.html.erb template:

priority /.*txt/ => 2, 'index.html.erb' => 1

The default priority is 0 for all files.

Usage

Command Line

Always execute the stasis command in the root directory of your project.

Development mode (auto-regenerate on save):

$ stasis -d

Only render specific files or directories:

$ stasis -o index.html.haml,subdirectory

Change the public (destination) directory:

$ stasis -p ../public

Ruby Library

Instantiate a Stasis object:

stasis = Stasis.new('/path/to/project/root')

Optionally specify a destination directory:

stasis = Stasis.new('/project', '/html')

Render all templates:

stasis.render

Render a specific template or directory:

stasis.render('index.html.haml', 'subdirectory')

Supported Markup Languages

Stasis uses Tilt to support the following template engines:

Server Mode

Stasis can run as a server that uses redis to wait for render jobs.

Stasis server that uses redis on port 6379:

$ stasis -s localhost:6379/0

Push to the server (in Ruby):

Stasis::Server.push(
  # Paths to render
  :paths => [ "index.html.haml", "subdirectory" ],

  # Made available to views as `params`
  :params => {},

  # Redis address
  :redis => "localhost:6379/0",

  # Return rendered templates (false by default)
  :return => false,

  # Block until templates generate (false by default)
  :wait => false,

  # Write to the filesystem (true by default)
  :write => true,

  # Cache ttl for returned templates (nil by default)
  :ttl => nil,

  # Force write even if cached (false by default)
  :force => false
)
