I wouldn't have had this much control of my own environment with another language, so that all of these are pure Ruby:
- My window manager - My shell - My terminal, including the font renderer. - My editor - My desktop manager
That's less than 10k lines of code. I've taken it a bit to the extreme, but I wouldn't have had the time to if I had to fight a more verbose language.

Beware that one of the joys of writing these for my own use is that I've only added the features I use, and fixed bugs that matter to me, and "clean enough to be readable for me" is very different from best practice for a bigger project.
I'm slowly extracting the things I'm willing to more generally support into gems, though.
That's something that you could submit as a post here in HN
The biggest issue with these projects is that I feel uncomfortable pushing a few of them because I make a living of providing development and devops work, and my personal "only has to work on my machine and certain bugs are fine to overlook" projects are very different to work projects in how clean they are etc... But as I clean things up so they're closer to meeting my standards for publication I'll post more.
