I'm rewriting the wrapper I've been using for a couple years to connect to Lord of the Rings Online, a windows app that runs great in wine/dxvk, but has a pretty labyrinthine set of configs to pull down from various endpoints to craft the actual connection command. The replacement I'm writing uses proper XML parsing rather than the existing spaghetti-farm of sed/grep/awk/etc. I'm enjoying it quite a bit.
