Slack Custom Theme

I've come across a lot of custom themes for slack that are Mac/linux only. This is powershell script will ease the installation of any custom theme. You can use any theme that you would like, local or even through a url from the web. When prompted just enter exact url or file path to your css file (theme).

Prerequisites

1. Please have NodeJS Installed.

2. If they're fonts used in the theme you will have to manually installed those specified by the theme designer.

3. You must have Powershell 5.0, aka Windows 10 to get full compatibility. If you don't have Windows 10 install the latest powershell for windows.

4. When running this script always run powershell in Adminstrator Mode. Hit your windows start button then type powershell, right click powershell, then Run as administrator.

Note:

• These instructions are error handled in the script.
• Please restart/close powershell if you have installed NodeJS during this install. This will refresh your environment variables to which NodeJS/Windows uses for commands. If you have Chocolatey installed just type refreshenv while in powershell and run the install command below without closing/restarting powershell.

Install

To install theme just open powershell as administrator (Refer to #4 above) and run this command below.

Potential Errors

1. If you get an error when you try and run the install command above you might need to change the execution policy (i.e. enable Powershell). You need to be an administrator on your computer to do this.

   Open powershell(Refer to #4 above) and run this command: Set-ExecutionPolicy RemoteSigned -scope CurrentUser

2. If you happen to get this error. While the command npx asar extract app.asar app.asar.unpackedcustom has run:

npm ERR! code ENOLOCAL
