Shell sourced function not available to executed script

Shell sourced function not available to executed script

[Clint Priest]

I could be wrong, but I swear that a function declared in my shell 
environment was available to another script executed from the CLI.

In my case, I have a function:

pv() {
     echo "\$$1='${(P)1}'";
}

Which is `source`ed into my environment.  I could type pv PATH and it 
would echo:
$PATH='...'

However when I run another script with executability set, shebang is 
#!/bin/zsh it tells me pv is not available.

Any ideas?

It would also seem that 'autoloaded functions' are also not available 
from executed scripts...  I created it as an autoloaded function and it 
works from the CLI just fine.

This is going to depend on which of your startup files contain the
"source" or "autoload" commands.  Interactive and login shells load a
different set of ~/.z* files than do scripts.  Scripts typically read
only /etc/zshenv and ~/.zshenv.  For complete details, "man zsh" and
read the section on "Startup/Shutdown Files" (or section 5.1 in "info
zsh" if you have that available).

Makes sense, I'm not sure but I don't think bash behaves in this way.  
No matter, I can follow this pattern as well, thank you.
