# go-config

 Simpler Go configuration with structs.

## Features

- Declare configuration with structs and tags

- Type coercion out of the box

- Validation out of the box

- Pluggable resolvers

- Built-in resolvers (flag, env)

- Unambiguous resolution (must be specified via `from`)

## Example

Source:

```go

package main

import (

  "log"

  "os"

  "time"

  "github.com/tj/go-config"

)

type Options struct {

  Timeout     time.Duration `desc:"message timeout"`

  Concurrency uint          `desc:"message concurrency"`

  CacheSize   config.Bytes  `desc:"cache size in bytes"`

  BatchSize   uint          `desc:"batch size" validate:"min=1,max=1000"`

  LogLevel    string        `desc:"log severity level" from:"env,flag"`

}

var options = &Options{

  Timeout:     time.Second * 5,

  Concurrency: 10,

  CacheSize:   config.ParseBytes("100mb"),

  BatchSize:   250,

}

func main() {

  config.MustResolve(options)

  log.Printf("%+v", options)

}

```

Command-line:

```

$ LOG_LEVEL=error example --timeout 10s --concurrenct 100 --cache-size 1gb

```
