I wanted to have Sublime Text highlight x86 assembly, so I downloaded the package following - https://packagecontrol.io/packages/GAS-x86%20(or%20x64)%20highlighting%20scheme
However, I closed, reopened, quit and launched Sublime Text and all my assembly files are still being highlighted with the R syntax. The drop-down menu shows no option for AT&T x86 Assembly.
Console says
ignored packages updated to: ["GAS-x86 (or x64) highlighting scheme", "Vintage"]
