Magit forge for Gitlab in Doom Emacs

This guide assumes you're working on a Unix-like environment. I'm using Linux Mint (Ubuntu). It should work on Macs, and might on Windows.

These are the four steps you can use as a checklist, see the headings below for the details on each step.

• Enable forge support
• Create a Gitlab API key
• Add your gitlab credentials to ~/.authinfo.gpg

macOS Yosemite and above utilize AWDL (Apple Wireless Direct Link) to handle data transfers to other AWDL-enabled devices (Macs, Macbooks, iPhones, etc.) over the Wifi Radio, without the need for a common underlying Access Point.

However, whenever AWDL is active (Bonjour discovery and any Airdrop, Airplay, and GameKit links and transfers), it will lock the Wifi radio for small intervals. For Bonjour discovery specifically, this comes to an effective packet spooling time of about 50-100ms, once per second (active transfers will be higher).

Obviously, this will create unacceptable latency spikes for low-latency desktop streaming apps. To disable the AWDL interface, use the following command in Applications > Utilities > Terminal (this requires you to be logged in as an Administrator and enter your password):
