using variables from .zshenv in shell scripts

using variables from .zshenv in shell scripts

[TJ Luoma]

Either something weird is happening or I'm missing something really
basic here. (I blame the cold I've had for 2 weeks.)

I have some variables set in ~/.zshenv which I want to use in shell scripts

However, those variables do not seem to be defined when the shell script runs.

For example, if I have this in ~/.zshenv :

export FOO='BAZ'

and then have a shell script:

#!/bin/zsh

echo "Foo is $FOO"

exit 0

shouldn't it output "Foo is BAZ" ?

Instead, I am getting "Foo is "

I thought that shell scripts would read from ~/.zshenv unless the
first line of the shell script included the '-f' such as "#!/bin/zsh
-f"

is there a 'setopt' that I'm missing here?

(How have I been writing shell scripts for this long and I'm still not
getting something this basic???)

Is there possibly a value for ZDOTDIR already in your environment when
the script runs?

It's also possible that /etc/zshenv is doing something that causes your
$HOME/.zshenv to be skipped.

Try using

     #!/bin/zsh -x

in the script to see what's actually executing.

Now it's doing it, when it wasn't before.

I am left to assume that I had somehow managed to not actually save
the changes to my ~/.zshenv or some such oddity, because I cannot
duplicate it now.

*sigh*

All I need is 3-4 weeks of sleep and I'm sure I'll be back on top of things.

Sorry for the bother
