## Key Features
- Compatible with both [classic microformats](http://microformats.org/wiki/Main_Page#Classic_Microformats) and [microformats2](http://microformats.org/wiki/microformats2) syntaxes.
- Provides a [CLI](https://en.wikipedia.org/wiki/Command-line_interface) for extracting microformats from a URL, file, or string.
## Getting Started
Before installing and using microformats-ruby, you'll want to have Ruby 2.2.9 (or newer) installed. It's recommended that you use a Ruby version managment tool like [rbenv](https://github.com/rbenv/rbenv), [chruby](https://github.com/postmodern/chruby), or [rvm](https://github.com/rvm/rvm).
microformats-ruby is developed using Ruby 2.4.4 and is additionally tested against version 2.5.1 using [Travis CI](https://travis-ci.org/microformats/microformats-ruby).
## Installation
If you're using [Bundler](https://bundler.io) to manage gem dependencies, add microformats-ruby to your project's Gemfile:
```ruby
source 'https://rubygems.org'
gem 'microformats', '~> 4.0', '>= 4.0.9'
```
…and then run:
```sh
bundle install
```
You may also install microformats-ruby directly using:
```sh
gem install microformats
```
## Usage
An example working with a basic [h-card](http://microformats.org/wiki/h-card):
```ruby
source = ''
collection = Microformats.parse(source)
# Get a copy of the canonical microformats hash structure
collection.to_hash
# The above as JSON in a string
collection.to_json
# Return a string if there is only one item found
collection.card.name #=> "Jessica Lynn Suttles"
```
Below is a more complex markup structure using an [h-entry](http://microformats.org/wiki/h-entry) with a nested h-card:
```ruby
source = '
Microformats 2
'
collection = Microformats.parse(source)
collection.entry.name.to_s #=> "Microformats 2"
# Accessing nested microformats
collection.entry.author.name.to_s #=> "Jessica Lynn Suttles"
# Accessing nested microformats can use shortcuts or expanded method
collection.entry.author.name #=> "Jessica Lynn Suttles"
collection.entry.properties.author.properties.name.to_s #=> "Jessica Lynn Suttles"
# Use `_` instead of `-` to return property values
collection.entry.author.first_name #=> "Jessica"
collection.rel_urls #=> {}
```
Using the same markup patterns as above, here's an h-entry with multiple authors, each marked up as h-cards:
```ruby
source = '
Microformats 2
'
collection = Microformats.parse(source)
# Arrays of items will always return the first item by default
collection.entry.author.name #=> "Jessica Lynn Suttles"
collection.entry.author(1).name #=> "Brandon Edens"
# Get the actual array of items by using `:all`
collection.entry.author(:all).count #=> 2
collection.entry.author(:all)[1].name #=> "Brandon Edens"
```
### Command Line Interface
microformats-ruby also includes a command like program that will parse HTML and return a JSON representation of the included microformats.
```sh
microformats http://tantek.com
```
The program accepts URLs, file paths, or strings of HTML as an argument. Additionally, the script accepts piped input from other programs:
```sh
curl http://tantek.com | microformats
```
