This is a page about »My Shell Configuration«. I used fish for a while, but

get zsh & packages 

sudo port install zsh
sudo port install zsh-syntax-highlighting
sudo port install zsh-autosuggestions
sudo sh -c 'echo /opt/local/bin/zsh >>/etc/shells'
sudo chpass -s '/opt/local/bin/zsh' "$USER"

get fuzzy shell history

I use fzf (see HN discussion (ycombinator.com)). Alternatives are atuin (github.com) or mcfly (github.com).

sudo port install fzf
echo "source /opt/local/share/fzf/shell/key-bindings.zsh" >> ~/.zshrc
echo "source /opt/local/share/fzf/shell/completion.zsh">> ~/.zshrc

tweak .zshrc

# Goal 1: A nice prompt
PROMPT='%F{33}i%f%F{39}a%f%F{38}n%f%F{44}pan%f%F{50}@%f%F{43}ar%f%F{44}ch%f%F{38}:%1~/%f %F{44}%#%f '

# Goal 2: No duplicate history when reverse-searching my commands
HISTFILE=~/.zsh_history
SAVEHIST=100000 # Max entries saved to file.
HISTSIZE=100000 # Max entires for in-memory history.

# HISTDUP=erase
setopt    appendhistory     #Append history to the history file (no overwriting)
setopt    incappendhistory  #Immediately append to the history file, not just when a term is killed

setopt hist_ignore_dups  # Collapse two consecutive idential commands.
setopt hist_find_no_dups  # Ignore duplicates when searching history.
setopt share_history  # Share across concurrent sessions (append immediately, read from files, add timestamps).
setopt hist_ignore_space  # Lines that begin with space are not recorded.
setopt hist_verify  # Don't auto-execute selected history entry.
setopt hist_ignore_all_dups  # If a history entry would be duplicate, delete older copies.

# Goal 3: Case insensitive completion --> solved with fzf

# Goal 4: Emacs-style keybindings
    # Ctrl-a: jump to line beginning (same as pressing Home).
    # Ctrl-e: jump to line end (same as pressing End).
    # Alt-backspace: backspaces a whole word.
    # Ctrl-k: delete from current position to end-of-line.
    # Ctrl-a Ctrl-k: delete whole line (it’s a combination of “jump to line beginning” and “delete from current position to end-of-line”)
    # Alt-b: jump left a whole word
    # Alt-f: jump right a whole word
bindkey -e

# Goal 5: Zsh syntax highlighting
source /opt/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh 

# Goal 6: Get autocompletion
source /opt/local/share/zsh-autosuggestions/zsh-autosuggestions.zsh
