slack-dark-theme for Mac for Slack 4

Update October 2019: Slack released an official dark theme! https://slack.com/help/articles/115004846068-slack-updates-and-changes

Instructions and resources for modding Slack 4 with a dark theme. Working as of 8/2019.

Pre-requisites:

• Slack 4
• node/npm
• npm package asar installed globally (npm i -g asar)

Installation

• Clone or download this repository
• Run hack-slack.sh in a terminal (requires sudo privileges)

Make CSS Changes (or Create Your Own Theme)

• In downloaded repository, edit slack-dark.css and re-run hack-slack.sh in a terminal and then reload slack

CSS Current State

The CSS currently checked in is from an older version 3 of Slack, so some functionality is missing dark CSS rules. I'll add these when I have time. Feel free to submit a PR if you have CSS fixes you want to share.

How to Undo this change

• Edit the file /Applications/Slack.app/Contents/Resources/app.asar.unpacked/dist/ssb-interop.bundle.js (requires sudo) and remove everything between START_SLACK_DARK_MOD and END_SLACK_DARK_MOD
• Run pack.sh
• Reload Slack
