My zsh setup

This is mostly in git for my benefit, but you're welcome to use it.

Features

Non-exhaustive list:

Uses Starship for prompt; customise to your taste
Lots of fzf
Lots of completions (via plugin)
Syntax highlighting at prompt (via plugin)
Sensible settings (IMO ;)
Fast startup (makes use of recompilation and caching)
Shows unattached tmux sessions at login, as I use tmux for everything
Show time output for commands which took >10s to run
Stores a log of what was enabled/configured during startup
Sets up some hashed dir names (if the targets exist)
- ~src is ~/src
- ~tmp is ~/tmp
- ~icloud is iCloud Drive
Strongly prefers neovim if it's available (else vim); sets up nvim as man page viewer
Sets up a bunch of ls-type aliases to exa if installed
- ll, la for long and "all" lists
- lg for exa's "git" display
Lazy-loads nvm, because it takes a million years to run the first time
Lazy-compile completions (can cause harmless errors on shell launches after an upgrade)

Again, non-exhaustive.

t will launch or attach a tmux session. The one used depends on the terminal size (local or fullscreen). I always run in a tmux session, so I just run t as the first thing in a window, generally.
rv uses rg to search files, then uses fzf to let you pick one to open in vim
fv likewise uses fd to search matching filenames, and uses fzf to pick
venv will activate a virtualenv in ./.venv if it exists, else offer to create it and install requirements
gita uses fzf to give you an interactive file-picker for committing to git
try followed by a command will run that command with exponential backoff until it succeeds; great for try ssh ... after rebooting a host. Also good with history expansion: try !!
aws-profile switches profiles from your awscli config with tab-completion; aws-region for regions (I think the list is probably out of date ;)
There's a bunch of other aws functions in there; check out the local-plugins/aws stuff if they're of interest
If neovim is installed, then vim and vi are aliased to it; $EDITOR and $VISUAL are set too.
run-docker IMAGE runs that image and gives you a bash shell
tidy-docker gets rid of cruft
cat is aliases to bat if it's installed
show-certificate dumps a TLS cert file with openssl

Ctrl-r for fzf-powered shell history
Ctrl-t for fzf-powered filename picker
Alt-c for fzf-powered directory picker
Alt-d for fzf-powered directory history
Ctrl-x e to edit current command line in vim
Alt-f to accept forward a word from the autosuggest display; right-arrow to accept the whole line

You will need (for best results):

zsh, probably a recent one like >= 5.2 or 5.3
a modern terminal which can do things like 256 colours (or true colours)
one of the Nerd fonts as this uses glyphs from that
zplugin, which installs and manages some plugins. This should work without though, but not as well

You probably want:

On macOS you can install all of those with homebrew.

clone this repo to ~/.zsh: git clone https://github.com/jamesoff/zsh.git ~/.zsh
link files: for i in .zshrc .zprofile .zshenv; do ln -s "$HOME/.zsh/$i" "$HOME/$i"; done
when you run zsh for the first time, zplug will download and install the plugins required
