Loop over a string in zsh and Bash
I would like to convert this Bash loop:
x="one two three"
for i in ${x}
do
echo ${i}
done
in such a way to work with both Bash and zsh
This solution works:
x=( one two three )
for i in ${x[@]}
do
echo ${i}
done
Anyway I am modifying x from a string to an array.
Is there a way to loop over $x in zsh when it is a string and in a way compatible with Bash?
I know about zsh setopt shwordsplit to emulate Bash, but I can't set it ad hoc for the loop, because it would not work in Bash.

if type emulate >/dev/null 2>/dev/null; then emulate ksh; fi
In zsh, this activates options that make it more compatible with ksh and bash, including sh_word_split. In other shells, emulate doesn't exist so this does nothing.

If you are not afraid to use eval (= evil):
x="one two three"
eval "x=($x)"
for i in ${x[@]}; do
echo $i
done
