What is the main difference between source and install

[RayZ0rr]

I am simple zsh user. My main plugins are :

zsh-users/zsh-autosuggestions     
zsh-users/zsh-completions         
zsh-users/zsh-syntax-highlighting 

These are already complicated because of compinit and source order importance (at the very end of .zshrc) of zsh-syntax-highlighting

What command should I use to install these?

Example zshrc has no mention of install . however it is mentioned in the README

source is for starting plugins. install is for making new commands or completions available to you. The latter originally it made symlinks to executables and functions, like a package manager would. However, I decided that is not the best way to do things, since it requires all kinds of maintenance. Thus, now it simply adds things to your $path or $fpath and autoloads functions for you. As such, it really doesn't contain much logic anymore that you couldn't add to your .zshrc file yourself. I will probably deprecate it soon and then remove it some time later.

So, given the repos you listed, this is the correct code to add to your .zshrc file:

znap clone zsh-users/zsh-completions
$fpath=( ~[zsh-users/zsh-completions] $fpath )
    
znap source zsh-users/zsh-autosuggestions     
znap source zsh-users/zsh-syntax-highlighting
