copying slack emoji between servers

**** Script will take about an hour to upload a few thousand emoji ****

1) Go to the emoji list webpage for your Slack team and save the HTML as emoji.html
2) Download all of the emoji with a Python script:

	import re
	import urllib

	f = open('./emoji.html')
	line = f.read().replace('\n', ' ')
	matches = re.findall( r'(emoji\.slack\-edge\.com\/.+?\/(.+?)\/.+?(\..+?))\"', line, re.M)
	print str(len(matches)) + " icons found."
	for m in matches:
		filename = m[1] + m[2]
		url = "https://" + m[0]
		urllib.urlretrieve(url, filename)
		
3) Clone this repo: https://github.com/CodeBuffet/Slekkel
4) Follow the installation instructions, but don't run it yet
5) Add your emoji to the "emoji_to_upload" folder
6) Add support for JPEG files in Main.coffee:

		modify:
			
			if stat.name.endsWith(".png") or stat.name.endsWith(".gif")
		
		to:
		
			if stat.name.endsWith(".png") or stat.name.endsWith(".gif") or stat.name.endsWith(".jpeg") or stat.name.endsWith(".jpg")

7) The program doesn't work with more than ~250 files because the command gets too long for Bash. Change everything after "prompt.start()" in Main.coffee to: (this runs all batches concurrently)


prompt.start()
prompt.get properties, (err, result) ->
  if err
    console.log err
    return null

  listEmoji (files) ->
  
    batch = []
    filesLength = files.length
    i = 0
    while i < filesLength
      batch.push files[i]
      if i % 250 == 0 or i + 1 == filesLength
        binPath = './node_modules/casperjs/bin/casperjs'
        childArgs = [
          '--ssl-protocol=any'
          '--engine=slimerjs'
          path.join(__dirname, 'Scrape.coffee')
          result.domain
          result.email
          result.password
          batch.join('...')
        ]
        childProcess.execFile binPath, childArgs, (err, stdout, stderr) ->
          console.log 'Result:\n' + stdout + '\nerror: ' + err + ' ' + stderr
        batch = []
      i++
    
  return null
  
  
7) Quit Slack - it tries to pull the emoji list every time you add an emoji and melts your computer
8) Run the script ("make run")
	
	When it asks for the team name, that's the short name: e.g. http://myteam.slack.com is "myteam"
