Why reply on Slack with just "ok" when you can reply with 
instead!?!
This project contains a script to generate HTTP status code icons or emoji; useful for uploading to a Slack instance if you are geek/API/REST/HTTP inclined.
The script is a bash sell script, gen-status-code-icons.sh. Run it to generate the icons in gen.
png generation only works on Mac OS X where the rsvg-convert tool exists. This tool could be enhanced to use another tool.
The templates (2xx.svg, 4xx.svg, 5xx.svg) were derived from rest-codes plastic theme (ISC license); I tweaked them to make the text larger and aligned better.
