MicroPub support for Static Blog Engine

This php script provides micropub support for Static Site Generators. Incoming posts are rewritten to a suitable front-matter format and saved to the user's content store.

Currently, the script will handle the following indieweb functions:-

notes
articles
replies, adding the title of the article/note you are replying to. Replies can be syndicated to external services.
photos, note that this functionality requires the use of JSON-posts. nanopub is not presently equipped to handle multipart uploads
checkins, this functionality is heavily informed by OwnYourSwarm and the format that service uses
bookmarks
like-of
repost

nanopub offers the following functionality as described in the formal Micropub Specification

Required

Supports header and form parameter methods of authentication
Supports creating posts using x-www-form-urlencoded syntax

Optional

Supports updating and deleting posts
Supports JSON syntax and source content query
Supports replacement and deletion of limited set of properties
As it uses a separate Media Endpoint it provides configuration query

Full implementation report is available on micropub.rocks

nanopub additionally supports syndication of content to external silos. Currently it provides syndication to Twitter and Mastodon, although it also provides a framework implementation for any modern API-based endpoint. An example is provided of the script pinging the micro.blog service to update the user's feed.

The code is self-explanatory and documented, and can be adjusted easily to meet different needs.

Installation

Clone the contents into the static folder of your Hugo installation.

Since the 1.2 release, nanopub requires the use of Composer. Getting it to do all the things I wanted it to do was getting way beyond my skill level.

You'll need to set your site up with the requisite headers to:

Use IndieAuth as an identity/token service
Identify nanopub.php as your site's micropub endpoint

On my site, these headers are provided as follows:

<!-- indieweb components  -->
  <link rel="authorization_endpoint" href="https://indieauth.com/auth" />
  <link rel="token_endpoint" href="https://tokens.indieauth.com/token" />
  <link rel="micropub" href="https://ascraeus.org/nanopub.php" />

Then you'll have to configure the options in configs.php

Twitter Keys can be obtained using the Create New App on twitter.
Mastodon Keys are more command-line driven, but relatively straightforward. See the Mastodon API documentation
As Mastodon is a federated network, you do need to explicitly specify your Mastodon Instance.
If using the micro.blog function, you need to specify your site's rss/atom feed.
To use the weather data, you'll need to add access data for a location-tracking endpoint (like a self-hosted version of Compass) and a DarkSky API Key
Since 1.5, you can configure the frontmatter format for your posts. Currently the options are json, used in Hugo, or yaml, optionally used in Hugo, but required by other static engines such as Jekyll or Metalsmith. This could be used with other generators, such as Pelican, but the script would need to be changed to meet their specific format requirements.

Client Notes

nanopub expects data inputs in accordance with the current (May 2017) Micropub Spec, and does not gracefully handled deprecated formats. In particular:

mp-slug, not slug when setting the content of the slug property
mp-syndicate-to not syndicate-to when setting syndication targets for POSSE

Any errors resulting from use of the deprecated formats are a matter for the client.

TODO

Save all content in the correct Hugo JSON format
Read all content from disk in correct microformats2 syntax
Make it work with a more complete set of micropub features

Make a setup.php script to complete the required configuration settings.
Implement rsvp's, itineraries &c
Trigger sitegen on succesful operation.
