## Config
|
|
|
|
Package config allows other packages to require a certain section of TOML
|
|
configuration file to be parsed into its internal configuration structure. Once
|
|
config file is processed its values are distributed by the packages that
|
|
required them.
|
|
|
|
```go
|
|
import "github.com/localhots/gobelt/config"
|
|
```
|
|
|
|
Describe configuration structure inside a target package then call
|
|
`config.Require` from the init function of a package.
|
|
|
|
> Note: subgroups are not currently supported. If a package is called `s3` and
|
|
> located in `aws` parent package, call config section `aws_s3` instead of
|
|
> `aws.s3`.
|
|
|
|
```go
|
|
package db
|
|
|
|
var conf struct {
|
|
Flavor string `toml:"flavor"`
|
|
DSN string `toml:"dsn"`
|
|
}
|
|
|
|
func init() {
|
|
config.Require("db", &conf)
|
|
}
|
|
```
|
|
|
|
Load configuration from a `main` function of the app:
|
|
|
|
```go
|
|
package main
|
|
|
|
func main() {
|
|
config.Load("config/config.toml")
|
|
}
|
|
```
