Is there a way to do the type of auto-suggestion Fish does in Zsh?
Zsh has predict, run the commands below this and then hit Ctrl-X 1
or just type predict-on
to give it a try
#-*-shell-script-*-
autoload predict-on
autoload predict-off
# you may also wish to bind it to some keys...
zle -N predict-on
zle -N predict-off
bindkey '^X1' predict-on
bindkey '^X2' predict-off
https://github.com/tarruda/zsh-autosuggestions does exactly what I wanted. If you want fish-style autopredictions in zsh, use that.
