notes on giving jj a try

• add .jj to ~/.config/git/exclude so git ignores .jj directories anywhere on my system
• clone my work repo to a directory on disk and switch into it, then run jj git init --git-repo .
  • This creates a .jj folder, but the backend format is still git
  • jj has a backend format but it's not v1 yet, and this allows you to still do get stuff as necessary (though it's not recommended)
  • I initially tried to clone from github, but that didn't work, so using regular git to pull from github and then init jj
• At work we develop on the next branch; jj warned me on init that that branch wasn't tracked
  • it offered me the jj bookmark track next@origin command, so I ran it
  • I'm vaguely aware that a bookmark corresponds to git's idea of a branch, but that's about it
• it warned me about not having a user and email configured, and offered commands to set them
  • jj config set --user user.name "Bill Mill" && jj config set --user user.email "bill@billmill.org"
• Then, it warned that I needed to set the current commit to my user
  • jj always has you "in a commit" even when you haven't done anything; there's no such thing as untracked changes in a jj world I guess
  • So, finally, I'm in a checkout of my repo at HEAD:

$ jj describe --reset-author --no-edit
