This is a holding pen for my slack emoji-related manipulation scripts. I use Imagemagick for most of them, and often use the spectacular scripts gif2anim and anim2gif for manipulating/optimizing gifs frame-by-frame.
One can mass-download and mass-upload emoji from/to organizations you have access to, using the download-emoji.sh and upload-emoji.js scripts. This is particularly useful for when one organization has generated a large number of emoji you consistently find yourself reaching for. Now you can have them everywhere you use slack!
You'll need :
jq,wget,- a passing familiarity with the "Network" tab of Chrome Dev Tools Tools
From slack, navigate to your org's customize/emoji page.
If that option isn't present, don't despair! You can still download
emoji from a slack workspace which is set up to disallow non-admins
from customizing emoji. Add /customize/emoji to the end of the url
that appears below your org's name.
Open developer tools to the Network tab, reloading the page if necessary to populate it with requests.
Search for emoji.list and copy the response for the corresponding request, saving it in some file.
If the emoji.list request isn't in the Network tab, search instead for
emoji.adminList, and use "copy as cURL". Then edit the URL to which
this request is made, substituting emoji.list wherever you find
emoji.adminList. (The motivation for this is that the new URL is
paginated, so we want to use the older, unpaginated endpoint to get
the emoji list.) You can pipe the output from that command into a json
file like so:
You'll want to edit that specific part to read emoji.list, as well
as add a > and a filename to the end of the (rather long) curl
command, these last of which save the output to a file. After doing so
it should look like this:
On the command line, navigate to the directory to which you'd like to download all emoji and invoke the script
mkdir i-recommend-you-use-a-clean-directory
cd !$ # go there^
path/to/download-emoji.sh file-in-which-you-saved-the-responseThe download is quite likely to take a solid amount of time, (usually a few minutes on my macbook).
Now that you have a zillion (ahem) emoji on your computer, you can upload them to other organizations of which you're a part! You can be the Prime Minister of emoji in every slack you join!
Navigate to the customize/emoji page of the organization to which you'd like to upload emoji. (See the Emoji Download section for how to access this page.) Copy and paste the whole contents of the upload-emoji.js script into the javascript console of Chrome Dev Tools, and execute it. You can now drag-and-drop single or groups of files onto the "Choose a name" field, and they'll be uploaded to that organization.
