Estimate Reading Time

I use iA Writer and find the estimated reading time feature pretty handy. I thought it would be cool to add at the top of my blog articles on the web as others do.

How to Use

readingtime extends the Ruby String class, so you can call reading_time on any String object.

Install

gem install readingtime

In irb

$ irb
> require 'readingtime'
	=> true
> @words = "Lorem ipsum dolor sit amet"
> @words.reading_time
	=> "00:01"

In Your App

<article>

	<header>
		<h1><%= @article.title %></h1>
		<span class="readingtime">Estimated reading time – <%= @article.body.reading_time %></span>
	</header>

	<%= @article.body %>

</article>

And voila!

Options

You can also send in options to modify the formatting.

# Default output
@article.body.reading_time :format => :basic
=> "03:36"

# Longer text output
@article.body.reading_time :format => :long
=> "3 minutes and 36 seconds"
