znap pull command in a Zsh script?

[andylima]

Is there a way to execute the znap pull command in a Zsh script?

Thank you.

If you make sure that Znap has been sourced before you source the script, then yes, that should work. In Zsh, there’s no difference between calling commands from the command line, in your .zshrc file or from a script.

Oh, it's not a sourced script — it's a script file (where that command is) and I tried running it manually from the shell but I get an error that znap wasn't found.

I guess it won't work that way?... And there's no workaround?

@andylima I have no idea what you’re talking about. Can you please give a concrete example?

[andylima]

These are the contents of the script file:

#!/usr/bin/env zsh

# upd zsh plugins using `znap`
# ie: upd all zsh plugin repos

echo "=== Updating Zsh plugins ==="
echo

znap pull

The name of that script file is znu and it's on a folder that's part of my PATH. When I type znu and press Return, I get this error:

command not found: znap

@andylima I dug into it a bit and found out that what happens when you run your znu script as an executable, rather than sourceing it, it gets executed in a subshell. The subshell inherits exported parameters, but nothing else from the parent shell. So, for all practical purposes, when you run your script as such, it is as if Znap has never been initialized.

The easiest way around this is to convert your script to a function. So, instead of adding it to your $path, add it to your $fpath and autoload it. That way, it will run inside the same shell.

@marlonrichert I see. Thank you — I will use that workaround.
