I have a string that contains a JSON array. Each element of the array is another string. And for each element of the array, I want to end up with an environment variable with a name that is based on that string.

An example might make it clearer. I have this:

json='["foo", "bar", "baz"]'

And I want to end up with these environment variables:

FOO_VAR=1
BAR_VAR=1
BAZ_VAR=1

I guess there are two steps:

1. Convert JSON to a bash array
2. Walk the bash array, munging each string and setting a variable

I can probably do step 2, but I’m stuck on step 1.
