Microformats 2 parser for Haskell! #IndieWeb

Originally created for sweetroll.

  • parses items, rels, rel-urls
  • resolves relative URLs (with support for the <base> tag), including inside of html for e-* properties
  • parses the value-class-pattern, including date and time normalization
  • handles malformed HTML (the actual HTML parser is tagstream-conduit)
  • high performance
  • extensively tested

Also check out http-link-header because you often need to read links from the Link header!



Look at the API docs on Hackage for more info, here's a quick overview:

{-# LANGUAGE OverloadedStrings #-}

import Data.Microformats2.Parser
import Data.Default
import Network.URI

parseMf2 def $ documentRoot $ parseLBS "<body><p class=h-entry><h1 class=p-name>Yay!</h1></p></body>"

parseMf2 (def { baseUri = parseURI "" }) $ documentRoot $ parseLBS "<body><base href=\"base/\"><link rel=micropub href='micropub'><p class=h-entry><h1 class=p-name>Yay!</h1></p></body>"

The def is the default configuration.

The configuration includes:

  • htmlMode, an HTML parsing mode (Unsafe | Escape | Sanitize)
  • baseUri, the Maybe URI that represents the address you retrieved the HTML from, used for resolving relative addresses -- you should set it

parseMf2 will return an Aeson Value structured like canonical microformats2 JSON. lens-aeson is a good way to navigate it.
