hconf: HCL library for configuration files

hconf extends the Hashicorp HCL library and is intended to be used as configuration file format.

Configuration file API

hconf is based around a configuration file with sections, and each section can have key/value pairs.

Given a configuration file like this:

section "autoupdate" {
  release_channel = "test"
}

And a Golang structure like this:

type Config struct {
	Autoupdate      Autoupdate      `hsection:"autoupdate"`
}

type Autoupdate struct {
	ReleaseChannel hconf.String `hconf:"release_channel"`
}

This could be parsed like this:

hc := hconf.New(&hconf.Config{})
config := &Config{}

err := hc.DecodeFile(config, "path/to/config.conf")

// config.Autoupdate.ReleaseChannel now contains "test"

Future Ideas

• Adding conditional when support based on predicates or local command execution to allow a more flexiable configuration file. See predicate.go.
