convert a json dictionary into environment variables

jsonenv

#!/usr/bin/env python

# jsonenv reads a json object as input and produces
# escaped shell commands for setting environment vars

import json
import pipes
import sys

for k, v in json.load(sys.stdin).items():
    k = pipes.quote(k)
    v = pipes.quote(v)
    print "%s=%s export %s;" % (k, v, k)

pipes.quote is wrong for the env names. Env names can only contain word characters, so it should be instead sth like k = re.sub("[^a-zA-Z_0-9]+", "_", k)

Have you tried jq as an alternative?

$ jq -r '. | to_entries[] | "export \(.key)=\(@sh "\(.value)")"' ~/tmp/x.json
export URL='https://foo:bar@example.com/'
export OTHER='foo " bar '\''baz'\'''

That's not identical output to the Python above, but it is equivalent. (To encode single-quote (') characters, it uses <backslash>&apos; outside quotes instead of "'".)

Thanks

this should work without the need to paste code into cmdline again:

for k, v in json.load(open('local.settings.json')).items():
    os.environ[k] = v
