`read` doesn't have a `-a` option on my system

[galou]

I use zsh v5.8.1 on Ubuntu 22.04 but read doesn't have any -a option (read is a builtin in zsh). This page doesn't mention any -a option either.

What does -a do?

A simple test roscd my_package shows Package 'my_package' not found. when I remove the -a option.

A little more research gives me another page that mentions -a: "assign the words read to sequential indices of the array variable ARRAY, starting at zero".

The line starting with IFS can be replaced by IFS=':' paths=($(echo "$AMENT_PREFIX_PATH")) both on zsh and bash.

I pushed some changes to the zsh_compatibility branch. Please test if they work for you.
