go-yamlconfig

This is a small library for parsing yaml config files. The main advantage of this over plain yaml parsing is this library falls back on defaults block when getting key value, ie the way Rails defines its yaml config files.

Usage

Initialize client:

var exampleConfig = `
defaults: &defaults
 env: development

development:
 <<: *defaults // inherits from defaults

production:
 <<: *defaults   // inherits from defaults
 env: production // overrides defaults for this specific key
`

config, err := New([]byte(exampleConfig))
if err != nil {
  return err
}

Get default environment (development) config:

val, err := config.GetString("database")
if err != nil {
  return err
}

fmt.Println(val) // development

Get config from another environment:

// override environment
config.SetEnv(Production)
val, err = config.GetString("database")
if err != nil {
  return err
}

fmt.Println(val) // production

If config is not string, Get can be used to return an interface{} value:

val1, err := config.Get("database")
if err != nil {
  return err
}

fmt.Println(val) // production
