From 837cfe07c76df5e464e3cfc7e9a1f0e64a91c4b5 Mon Sep 17 00:00:00 2001 From: William Carroll Date: Fri, 31 Jan 2020 15:27:48 +0000 Subject: 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. --- blog/default.nix | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'blog') diff --git a/blog/default.nix b/blog/default.nix index 5359a0ab6f37..1b1cc3974805 100644 --- a/blog/default.nix +++ b/blog/default.nix @@ -1,7 +1,7 @@ { nixpkgs ? import {}, depot ? import {}, - universe ? import {}, + briefcase ? import {}, ... }: @@ -16,7 +16,7 @@ let ''; in depot.nix.buildLisp.program { name = "server"; - deps = with depot.third_party.lisp; with universe.third_party.lisp; [ + deps = with depot.third_party.lisp; with briefcase.third_party.lisp; [ hunchentoot cl-arrows ]; -- cgit 1.4.1
