Boost

Scripted Lua configuration for Go!

Boost is a simple configuration engine driven by Lua scripts.

Install

This package is go get-able so I'm sure you know what to do... (but just in case you don't ↲)

go get github.com/cosmotek/boost

Example

In addition to the example below, I've included an much more detailed example in the examples folder.

example.conf

-- some global values
random = {
  one = 1,
  two = 2,
  strawberries = "red"
}

-- configuration function
MyApp.configure = function(config)
  config.favorites.fruits = {
    "apple",
    "orange"
  }

  config.favorites.color = "red"
  config.favorites.animals = true
end

main.go

package main

import (
	"fmt"

	"github.com/cosmotek/boost"
	"github.com/cosmotek/boost/types"
)

type Configuration struct {
	Favorites struct {
    Color string
    Animals bool
    Fruits []string
  }
}

func main() {
	conf, err := boost.NewAppConfig(
		"MyApp",
		"example.conf",
    		// enabled debug logging
		true,
		types.NewString("name", "seth"),
	)

	defer conf.Cleanup()
	if err != nil {
		panic(err)
	}

	config := &Configuration{}
	err = conf.ParseFunction("configure", config)
	if err != nil {
		panic(err)
	}

	fmt.Println(config)
}

API Coverage

At the moment all Lua stdlib packages appear to be fully functional (os, io, file, math etc..) as well as a few Gopher-Lua modules for serialization, http and utility. Native/Pure Lua libraries and C-Wrapping modules are yet to be tested. Most pure Lua code should work, anything interfacing with C should not be expected to work.

Included Gopher-Lua Modules:

• http (http client wrapping net/http)
• re (regex)
• json
• yaml
• xmlpath
• url (parser)
• lfs (Lua Filesystem, not complete)

Shout-outs

Special Thanks to the creator of https://github.com/yuin/gopher-lua which this library is almost fully dependent on.

Contribution and maintenance

While Boost has been tested in small apps, be careful when using this library for anything in sensitive environments. If you would like to make a suggestion or report a bug, please feel free to submit a PR or issue. I really hope you enjoy using Boost! Thanks!
