TheFunk's twice patented AUR-Helper-Getter-Method
Remember, make sure you have administrative privileges before doing this.
The first thing you'll need is a means of downloading files, and making packages.
For making packages you'll need to run:
pacman -S base-devel
For downloading, my personal preference is the command line program wget, which can be installed with:
pacman -S wget
Following wget's installation, you're going to download two things, a file named PKGBUILD and a tarball containing your AUR helper's source. You'll be downloading these things from the AUR...how's that for irony? The AUR helper I installed is called packer. There are others out there but packer will suffice if you don't have a preference.
First, download packer's source by typing this:
Then download the PKGBUILD file with this:
Next, make your package:
makepkg -s PKGBUILD
And finally install packer:
pacman -U insert-name-of-file-that-makepkg-made-here
There you have it! Now anytime you want to install something from the AUR, you don't have to do this process again, packer will take care of it for you. The syntax for installing a package with packer, is similar to that of pacman, to install a package, just use the -S switch. Hopefully this tutorial was helpful! I basically elaborated on the tutorial found at the link below, I'm assuming that person won't mind.
