A collection of implementations of IndieWeb algorithms.

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

A collection of implementations of [IndieWeb]- and Microformats 2-related algorithms (based on microformats2-parser and http-link-header):

  • finding all microformats of a given type (while retaining the path to them), ie. flattening the tree
  • discovering authorship of an h-entry
  • discovering Webmention/Micropub/IndieAuth/etc. endpoints (HTTP Link header, a and link tags with the rel attribute)



{-# LANGUAGE OverloadedStrings #-}

import Network.HTTP.Link
import Data.Default
import Data.Maybe
import Data.Microformats2.Parser
import Data.IndieWeb.Endpoints

discoverEndpoints [ "micropub" ] (parseMf2 def $ documentRoot $ parseLBS "<link rel=micropub href=''>...") (fromMaybe [] $ parseLinkHeader "<>; rel=\"micropub\"")


Use stack to build.
Use ghci to run tests quickly with :test (see the .ghci file).

$ stack build

$ stack test && rm tests.tix

$ stack ghci --ghc-options="-fno-hpc"
