SocialParser

A small library for parsing out common social elements such as hashtags, mentions and urls.

Usage

Add social_parser to your list of dependencies in mix.exs:

def deps do
  [{:social_parser, "~> 1.1.0"}]
end

You can then parse out the social components like so:

defmodule SocialParserTest do
  def do_social_stuff() do
    message = "hi @you checkout http://example.com/ that +someone hosted #example"

    # parse out all components into an array
    components = SocialParser.parse(message)

    IO.inspect(components)
    # [
    #   {:text, "hi ", {0, 3}},
    #   {:mention, "@you", {4, 8}},
    #   {:text, " checkout ", {9, 19}},
    #   {:link, "http://example.com/", {20, 39}},
    #   {:text, " that ", {40, 46}},
    #   {:mention, "+someone", {47, 55}},
    #   {:text, " hosted ", {56, 64}},
    #   {:hashtag, "#example", {65, 73}}
    # ]

    # extract targeted components
    some_components = SocialParser.extract(message, [:hashtags, :mentions])

    IO.inspect(some_components)
    #%{
    #   hashtags: ["#example"],
    #   mentions: ["@you", "+someone"]
    #}
  end
end

TODO

• Merge the private parse and parse_components functions as there is some duplication of code
