|
|
Go package for app configuration. Supports chained configuration sources for multiple levels of defaults.
|
||
|
|
Includes APIs for loading Linux style configuration files (name/value pairs) or INI files, map based properties,
|
||
|
|
or easily create new configuration sources (e.g. load from database).
|
||
|
|
|
||
|
|
Supports monitoring configuration sources for changes, hot loading properties, and notifying listeners of changes.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```Go
|
||
|
|
config := &cfg.Config{}
|
||
|
|
defer config.Shutdown() // stops monitoring
|
||
|
|
|
||
|
|
// load file via filespec string, os.File
|
||
|
|
src, err := Config.NewSrcFileFromFilespec("./myfile.conf")
|
||
|
|
if err != nil {
|
||
|
|
return err
|
||
|
|
}
|
||
|
|
// add src to top of chain, meaning first searched
|
||
|
|
cfg.PrependSource(src)
|
||
|
|
|
||
|
|
// fetch prop 'retries', default to 3 if not found
|
||
|
|
val := config.Int("retries", 3)
|
||
|
|
```
|
||
|
|
|
||
|
|
See [example](./example_test.go) for more complete example, including listening for configuration changes.
