emojimage

An experiment in rendering images with Slack custom emojis.

Usage

1. Initializing your workspace

First, you'll need to upload 1,332 custom emoji to your workspace. Fortunately, there's a convenient script in this repo to do so!

First, grab a client API token from Slack. The only way to get one is to log in to your Slack workspace with a browser, open your devtool's "network" tab, and capture the token from a request. It'll look something like xoxc-123-45678-90.

Assuming you have Go installed, just run SLACK_TOKEN=xoxc-123 go run ./init (replacing xoxc-123 with your client token). ⚠️ This will upload 1,332 emoji to your Slack workspace, and could take up to an hour to run! Expect to run into a lot of rate limits (the included script will gracefully handle those).

2. Generating an image

To generate the message text for an image, simply run go run ./generate_image <path to PNG file> <optional width/height>. Only PNG files are supported out of the box.

The width/height parameter defaults to 20 (the value used in the above screenshot)

Copy the output, then paste it into Slack!
