moparisthebest's helix config

I use Unix Programmer's Dvorak for a keyboard layout, so when I started to learn helix, I wanted to keep all the keys in the same position, but mapped to Dvorak. There isn't even a default layout file for helix, so with some awful bash and a tiny bit of manual editing I managed to:

1. extract default keymap from helix source code (config.orig.toml)
2. automatically convert it to dvorak (config.dvorak.toml)

I'll also keep my personal config.toml here, where I may make more tweaks.
