I got up to some fishy business yesterday, and wrote a blog post about it

More seriously, I wanted to figure out how transient prompt works in projects like Powerlevel10k, and once I did I decided to write it down.

It's a bit sad that I rarely have enough energy for random exploration outside of a vacation… But at least it's good to know that my brain is not a boring tin can yet.

A small quality of life tip for when you are tinkering with your dotfiles (shell, in particular):

$ bash --norc --noprofile  # bash is everywhere, and disable user configs in case they are in a busted state. Feel free not to do.
bash-5.2$ while zsh; do true; done
my-fancy-zsh> cd ~git/dotfiles # Try the current config, see if it works.
my-fancy-zsh (errror, your git prompt is busted!)> # Oh no! Let's fiddle with .zshrc some more.
my-fancy-zsh (errror, your git prompt is busted!)> ^D # Ctrl-D to exit the shell.
my-fancy-zsh> # Restarted in a clean state!
my-fancy-zsh> cd ~git/dotfiles # Try again.
my-fancy-zsh (omg, something is not checked in )> # That's much better!
my-fancy-zsh (omg, something is not checked in )> exit 1 # We are done here.
bash-5.2$ ^D

This works much better than source ~/.zshrc because not everything in the rc file is idempotent and broken state from a bad attempt can mess with things. It spares me a lot of frustration of opening and closing terminal tabs, which is what computers are supposed to do for us.
