Zsh + async + zsh-snap

[Pakrohk]

was trying to rewrite my zsh config processes for more speed (as well as optimization) using the mafredri/zsh-async plugin.
Of course, my knowledge about this is limited, but I rewrote the config as follows:

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
  source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi

Now there are problems (zsh-snap) does not activate any of the plugins, what is the reason for the problem?!

[Pakrohk]

Well, I fixed it a bit like this, but I still haven't managed to activate the plugins properly.

First of all, you do not need mafredri/zsh-async to run asynchronous processes. You can simply use

exec {fd}< <( ... )

like znap multi does. Read the Zsh manual for more info:

• Opening file descriptors using parameters
• Process substitution

Second, asynchronous processes do not run in the main shell. They are subprocesses and those cannot affect the main shell directly. So, running your plugins asynchronously won't do a thing in your interactive shell.

Thirdly, you do not need to do any of this. You are already using Powerlevel10k's instant prompt feature.

Fourthly, doing async znap prompt romkatv/powerlevel10k makes absolutely no sense. You don't need znap prompt if you're already using P10's instant prompt feature; they do essentially the same thing, except that znap prompt works for any prompt theme. And wrapping this in async makes even less sense.
