Disable JSON flattening in .env

[dotchev]

For production we deploy to Cloud Foundry, but for local testing I think node-foreman could be very useful.

One thing I currently miss is the support for multiline env variables as these are heavily used in Cloud Foundry, e.g. VCAP_SERVICES

I think this will be easy to achieve by providing an option to disable JSON flattening of .env file. Instead the value of each root-level property is stringified.

Would you accept a PR for this?

@dotchev support for VCAP_SERVICES definitely sounds like a good idea to me. A PR would be great!

As a (really ugly) workaround in the meantime, you should be able to do this now by cramming it on to one line:

SOME_VAR=foo
VCAP_SERICES={"elephantsql":[{"name": "elephantsql-c6c60","credentials":{"uri":"postgres://seilbmbd:ABcdEF@babar.elephantsql.com:5432/seilbmbd"}}]}

Meanwhile I started a new project https://github.com/dotchev/fireup. It is similar to Foreman but uses a single yml file to describe multiple processes to start, each with its own env vars, work dir, etc. YAML is very flexible and allows for multi-line values using block literals.

VCAP_SERVICES: >
  {
    "elephantsql": [
      {
        "name": "elephantsql-c6c60",
        "label": "elephantsql",
        "tags": [
          "postgres",
          "postgresql",
          "relational"
        ],
        "plan": "turtle",
        "credentials": {
          "uri": "postgres://seilbmbd:ABcdEF@babar.elephantsql.com:5432/seilbmbd"
        }
      }
    ]
  }

Need multiline support as well. Some configuration such as certificate or private key are multiline. I haven't dig into the source but node foreman seems to take \n as \n instead of newline.

Ruby foreman support multiline with "\n" in the config string. https://github.com/ddollar/foreman/blob/master/lib/foreman/env.rb
