Thanks for explaining that! It looks like I can get what I want by writing
a function that does this:
set fnpath $fish_function_path[1]
funced $name; and funcsave $name; and source $fnpath/$name'.fish'
A related question:
Why does funced ask this question on exit?
"remove
/var/folders/jc/q4_2lrkd3pn2sz1l_s8rf31w0000gn/T//fish.DjETfi/baz.fish?"
Is that where it saves temporary (what I referred to as in-memory)
functions?
That isn't addressed in the help for funced.
I'm not sure how my answer to that question affects the function.
