Webmention Client

A Ruby gem for sending webmention (and pingback) notifications.

Installation

gem install webmention

Usage

Send webmentions to all links on a page

client = Webmention::Client.new url
sent = client.send_mentions

puts "Sent #{sent} mentions"

This will find all absolute links on the page at url and will attempt to send mentions to each. This is accomplished by doing a HEAD request and looking at the headers for supported servers, if none are found, then it searches the body of the page.

After finding either webmention or pingback endpoints, the request is sent to each.

Send webmention to a specific URL

# Discover the webmention endpoint of a target and send the mention

source = "http://source.example.com/post/100"   # For example, your page
target = "http://indiewebcamp.com/"             # The page you linked to

if endpoint = Webmention::Client.supports_webmention?(target)
  Webmention::Client.send_mention endpoint, source, target
end

Command Line Utility

For testing or for sending webmentions manually, you can use the command-line utility provided.

$ webmention http://source.example.com/post/100

This will look for an h-entry on the given URL and attempt to send webmentions to each URL in the entry.
