Very custom, to the point that the current iteration is dependent enough on a bunch of details of my environment (part of this is an ongoing drive towards minimalism - e.g. the editor doesn't know how to open files or select buffers or select themes; all of those things are delegated to scripts that currently use rofi) to the point I'm not convinced it'll even start on someone. I'm slowly cleaning it up to at least pretend it might work for someone else, but that means also deciding on a cleaner interface to the helper scripts so I don't have to package up my entire environment in one go.

The beauty of the DrB part of it, though, is that the shell of that is very small: Just spawn a DrB server, spawn a client, and wrap the client in a begin/rescue block with binding.pry, and put any critical data on the server side. Suddenly your server-side is near crash-proof and your data much less likely to disappear. If you want an extra level of protection, run a threat on the server side to checkpoint the data regularly (I used to checkpoint it every 5 seconds at the start; it's now at around 5 minutes, which also means every buffer I've opened and not bothered to kill from the last 5-6 years are still accessible... I never bothered to add code to clean them up as they just don't take up much space)
