SimpleConf

Needed a simple configuration library for my gems. Made public so everyone can take advantage!

##Install [sudo] gem install simpleconf

##Usage

Simple Configuration

CONFIG = SimpleConf {
    host "localhost"
    port 80
    blacklist [1,2,3]
}

CONFIG.host # localhost
CONFIG.port # 80
CONFIG.blacklist # [1,2,3]

Nested Configuration

CONFIG = SimpleConf {
  server {
    ip "0.0.0.0"
    port 8080
  }

  workers 50

  security {
    admin {
      only_from "127.0.0.1"
    }

    max_logins 5
  }
}

CONFIG.server.ip # "0.0.0.0"
CONFIG.workers # 50
CONFIG.security.admin.only_from # "127.0.0.1"
CONFIG.security.max_logins # 5

Merging

default = SimpleConf {
  host "localhost"
  port 80
}

new_config = default.merge( #also merge!
  SimpleConf {
    port 9999
  }
)

new_config.host # "localhost"
new_config.port # 9999

Overriding

config = SimpleConf {
  host "localhost", :override => false
  port 80
}

config.host "google.com"
config.host # Still "localhost"
config.port 9999
config.port # 9999

Lock configuration

default = SimpleConf(:init_only => true){
  host "localhost"
}

default.port 80 #throws error!!!

File Configuration

# basic.conf

server "localhost"
ports [80, 8080, 3000]
auth {
  user "mike"
  pass "password"
}

# code.rb

conf = SimpleConf.load("basic.conf")
conf.server # localhost
conf.ports # [80, 8080, 3000]
conf.auth.user # mike
# etc
