A Webmention implementation for Elixir

Read the documentation

Goals

• Send WebMentions
• Receive Webmentions (in progress)
• Configurable storage, defaulting to ets
• Easy local development and management of WebMentions including:
  • [ ] Accept
  • [ ] Decline
  • [ ] Verify
  • [ ] Block
  • [x] See Sent

Usage

All aspects of the library can be used piecemeal or as a supervised system.

Sending

When using piecemeal, the functions worth exploring are in Libmention.Outgoing:

• Libmention.Outgoing.parse/1 is used to parse an html document for all unique links. The idea here is to pass in the body of your post/note/comment and determine which urls may need to have a webmention sent.
• Libmention.Outgoing.discover/2 takes a link, sends a discovery and determines if webmention is supported at that specific link
• Libmention.Outgoing.send/4 sends a webmention

When using as a supervised system, add the Libmention.Supervisor to your supervision tree and configure it for sending.

config = [
  outgoing: [
    storage: Libmention.EtsStorage
  ]
]
children = [
  ...,
  {Libmention.Supervisor, config}
]

See Libmention.Supervisor for a full list of options

Then to send webmentions for a page or content,

Libmention.Supervisor.send(url, html)

When the process is done,

Receiving
