Veteran users of Archlinux scoff at AUR helpers, tools that automate certain tasks for using the Arch User Repository (AUR). If you listen to them, they all install packages from the AUR in the canonical way, i.e., via 'makepkg -si'. In reality, of course, they write their own scripts for interacting with the AUR. ;)

I've used yaourt from the start until it became clear that it has serious security issues. At that point I switched to pacaur, which was declared to be orphaned in December 2017.

Well, when looking at the table displayed in the AUR helper page, it's clear that there are a few promising candidates for a future AUR helper on my desktop. I finally opted for yay since I like the name and appreciate the support for all three shells I'm using. But what I like best is the system summary:

➜  ~ yay -Ps

The fifth biggest package in this list is atom, an editor. 244 MB for an editor? Well, there are very few applications that I'm using as much as an editor, and I'm thus constantly evaluating potentially promising newcomers in the editor/IDE category. Is atom worth the ¼ GB of disk space? You'll get the answer in the comprehensive editor shootout that I will post later this year. ;)
