[SOLVED] Using fish shell function within a script

Issue

I have a bunch of shell scripts, the first being one which installs the popular Fish shell. Once this step completes I copy a functions/ directory to the appropriate location. I then want to use the spin function to call each shell script and display a spinner, while each script is executing. However after I get passed the initial installation of Fish and configuration I am unable to use the functions i.e. spin <command> results in command not found.

NOTE This is happening within an ephemeral docker container for testing.

Any pointers or help with this, would be greatly appreciated.

Solution

If you want to run fish functions from outside fish, use fish -c with a fish command line as one string.

For example, this fails...

env __fish_pwd

...but this works:

env fish -c __fish_pwd

This is because env runs executables, not fish functions. I assume spin is like this too.
