RHP: Ruby Hypertext Preprocessor

This is a goofball project! Definitely not recommended for production.

An amazing thing about PHP is you can just run a server, sit some files in a directory, and boom, HTML templates.

This project imitates that workflow in Ruby! Run the server, drop some templates in a directory, and use ERB to just make some HTML.

Installation

Since this is just for messing around, install this gem from git source.

gem 'rhp', github: 'zachmargolis/rhp'

Usage

The RHP::Server class is a Rack handler that serves files out of a directory:

# config.ru
require 'rhp/server'

run RHP::Server.new('examples')
$ rackup config.ru

For a request to /something, we evaluate the examples/something.html.erb template.

<% header("X-Is-Super-Awesome: yes") %>

Hello from RHP! The year is <%= Time.now.year %>.

Which gives us:

curl -v http://localhost:9292/something
< HTTP/1.1 200 OK 
< Content-Type: text/html
< X-Is-Super-Awesome: yes
< 
Hello from RHP! The year is 2014.

Inside templates, the Rack::Request object is exposed as request so a lot of common PHP-isms translate easily. We also expose a few common functions for setting headers, response codes, etc.

PHP RHP
$_GET request.GET Access HTTP GET parameters
$_POST request.POST Access HTTP POST parameters
nl2br() nl2br Convert newline characters into <br /> tags
header() header Set header values
http_response_code() http_response_code Get or set HTTP status code
