Environments

bdlm/log has no notion of environment.

If you wish for hooks and formatters to only be used in specific environments, you should handle that yourself. For example, if your application has a global variable Environment, which is a string representation of the environment you could do:

import (
  log "github.com/bdlm/log"
)

init() {
    // Do something here to set environment depending on an environment variable
    // or command-line flag
    if Environment == "production" {
        log.SetFormatter(&log.JSONFormatter{})
    } else {
        // The TextFormatter is the default, you don't actually have to do this.
        log.SetFormatter(&log.TextFormatter{})
    }
}

This configuration is how bdlm/log was intended to be used, but JSON in production is mostly only useful if you do log aggregation with tools like Splunk or Logstash.
