How to make zsh completion show the first guess on the same line (like fish's)?

Question

In Fish when you start typing, autocompletion automatically shows the first autocompleted guess on the line itself.

In zsh you have to hit tab, and it shows the autocompletion below. Is there anyway to make zsh behave more like fish in this regard?

(I am using Oh My Zsh...)

Yes! That's awesome! You should write it up as an answer so people will see it. — korylprince, Oct 30 '13 at 16:16

I have implemented a zsh-autosuggestions plugin.

It should integrate nicely with zsh-history-substring-search and zsh-syntax-highlighting which are features ported from fish.

Highlighting with this doesn't work for me and a number of others and issues on the github don't seem to be addressed. See https://github.com/tarruda/zsh-autosuggestions/issues/12 – Eli Apr 28 '14 at 14:53
@Eli This plugin has recently been rewritten to address many of the issues. Feel free to give it another shot. – Eric Freese Feb 22 '16 at 14:16
Here's the thing about zsh-autosuggestions, it cues off of history which is often similar in effect as tab-completion, but it's entirely different. I think what many of us are looking for is for the exact value that tab would complete to be shown, instead. This is a very significant distinction... – Steven Lu Oct 03 '16 at 21:54
@StevenLu Tab-completion suggestions have been implemented on a feature branch. Take another look: https://github.com/zsh-users/zsh-autosuggestions/pull/330 – Eric Freese Jun 07 '18 at 05:15

Try:

autoload predict-on
predict-on

See:

info zsh --index-search=predict-on

for details.

This is technically the correct answer. However, the zsh predict support is rather abysmal compared to fish as it currently stands (at least with the configurations I tested.) – korylprince Jul 29 '13 at 22:36

How do you turn it off? – May 03 '19 at 21:03
I don't like this at all. – surj Oct 10 '19 at 20:49

Install oh-my-zsh

sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

Clone necessary plugins.

git clone https://github.com/zsh-users/zsh-autosuggestions $ZSH_CUSTOM/plugins/zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-history-substring-search ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-history-substring-search
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

Add plugins to ~/.zshrc as

plugins = ( [plugins...] zsh-autosuggestions zsh-history-substring-search zsh-syntax-highlighting)

Note: make sure zsh-syntax-highlighting is the last one in the above list.

Fix background theme issues (Not necessary depends on your theme.) Add the following line to your ~/.zshrc.

ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE='fg=white'

Restart zsh

source ~/.zshrc
