Rename dotfiles -> briefcase Renaming my mono-repo briefcase. I first introduced this commit in master, but it introduced a bug where one of two things would happen: 1. Emacs wouldn't start and would crash X. 2. Emacs would start but my keyboard wouldn't work. I learned some valuable debugging skills in the process. Here are some of them: When my keyboard was broken, I wanted to control my computer using my laptop. Thankfully this is possible by using `x2x`, which forward X events from the SSH client to the SSH host. ```shell > # I'm unsure if this is the *exact* command > ssh -X desktop x2x -west :0.0 ``` Git commit-local bisecting. I didn't need to do a `git bisect` because I knew which commit introduced the bug; it was HEAD, master. But -- as you can see from the size of this commit -- there are many changes involved. I wanted to binary search through the changes, so I did the following workflow using `magit`: - git reset --soft HEAD^ - git stash 1/2 of the files changed - re-run `nix-env -f ~/briefcase/emacs -i` - restart X session - If the problem persists, the bug exists in the non-stashed files. Repeat the process until you find the bug. In my case, the bug was pretty benign. Calling `(exwm/switch "Dotfiles")` at the bottom of `window-manager.el` was failing because "Dotfiles" is the name of a non-existent workspace; it should've been `(exwm/switch "Briefcase")`. There may have been more problems. I changed a few other things along the way, including exposing the env vars BRIEFCASE to `wpcarros-emacs` inside of `emacs/default.nix`. The important part is that this was a valuable learning opportunity, and I'm glad that I'm walking away from the two days of "lost productivity" feeling actually productive.
