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...)

Answer 1

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.

Answer 2

Try:

autoload predict-on
predict-on

See:

info zsh --index-search=predict-on

for details.

Answer 3

Follow the steps here to get other features as well: https://github.com/abhigenie92/zsh_to_fish

1. Install oh-my-zsh

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

2. 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

3. 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.

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

ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE='fg=white'

5. Restart zsh

source ~/.zshrc
