It doesn't append values period:
export FOO__HELLO=world

// config.json
{
  "foo": {
    "bar": "baz"
  }
}

// program.js

nconf
  .env({ inputSeparator: '__', lowerCase: true })
   .file('config.json')
 
console.log(nconf.get('foo'))

expected:

{ foo: { bar: 'baz', hello: 'world' }}

received:

{ foo: { bar: 'baz' }}

from nconf.

I've found the following to work @acceleratxr @LongLiveCHIEF 👍. Although it is obviously undocumented.

Run:

a__a=1 a__b=false node main.js

main.js:

const nconf = require("nconf");

nconf.env({ parseValues: true, separator: "__" });

nconf.defaults({
  a: { a: 3 },
});

console.log(nconf.get("a"));

output:

{ a: 1, b: false }

So in short when passing an object as config to the .env() function it needs a key of separator rather than inputSeparator.

Interestingly nconf.env("__") behaves correctly, but I needed additional config options.
