Tweetify angular filter. linkifies links, mentions and hashtags REF: https://gist.github.com/furf/2415595 Slightly changed tag regex so - (dashes) are not matched and changed the tag link to use ?q=%23

tweetify.coffee

app = angular.module 'myApp', []
 
tweetify = (->
  linkToUrl = (url) ->
    url.link url
  linkToUser = (match, atUser, user) ->
    atUser.link twitterUrl + "/#!/" + user
  linkToTag = (match, hashTag, tag) ->
    hashTag.link twitterUrl + "/search/?q=%23" + tag
  twitterUrl = "https://twitter.com"

  urlRegExp = /[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&\?\/.=]+/g
  atUserRegExp = /(@([A-Za-z0-9-_]+))/g
  hashTagRegExp = /(#([A-Za-z0-9_]+))/g

  (str) ->
    str.replace(urlRegExp, linkToUrl)
      .replace(atUserRegExp, linkToUser)
      .replace(hashTagRegExp, linkToTag)
