everyconfig

Use the same .yaml config files in every programming language

usage

Set up your config files in a directory like this:

.
├── config
|   ├── default.yaml
|   ├── production.yaml
|   └── test.yaml
├── foo
|   ├── foo.js
|   └── blue.js
└── bar
    ├── something.py
    └── post.py

Then set CONFIG_ENV to one of the names of your yaml files, like so: CONFIG_ENV=production node app.js

The best part is that all of your configs inherit the default values from default.yaml.

default.yaml:

db:
  url: 'localhost'
  port: 27017

production.yaml:

db:
  url: 'some.internal.dns'

resulting config for CONFIG_ENV=production:

db:
  url: 'some.internal.dns'
  port: 27017

node.js

var config = require('everyconfig')('./config')
console.log(config.mongodb.url)

(note that you can use NODE_ENV instead of CONFIG_ENV with node.js if you want)

python

from everyconfig import everyconfig
config = everyconfig('./config')
print config.mongodb.url

ruby

require 'everyconfig'
config = Everyconfig.load('./config')
puts c['mongodb']['url']

bash

from https://gist.github.com/pkuczynski/8665367 (note that if you use four space indents, your variables will be separated by two underscores instead of one)

everyconfig <config dir> <variable prefix>

source $path_to_everyconfig/bash/everyconfig.sh

# you should use an absolute path for the directory that holds your config files
DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )

#           directory        prefix
everyconfig "$DIR"/../config CONFIG_
echo $CONFIG_mongodb_url
