# Flag Source
|
|
|
|
The flag source reads config from flags
|
|
|
|
## Format
|
|
|
|
We expect the use of the `flag` package. Upper case flags will be lower cased. Dashes will be used as delimiters.
|
|
|
|
### Example
|
|
|
|
```go
|
|
dbAddress := flag.String("database_address", "127.0.0.1", "the db address")
|
|
dbPort := flag.Int("database_port", 3306, "the db port)
|
|
```
|
|
|
|
Becomes
|
|
|
|
```json
|
|
{
|
|
"database": {
|
|
"address": "127.0.0.1",
|
|
"port": 3306
|
|
}
|
|
}
|
|
```
|
|
|
|
## New Source
|
|
|
|
```go
|
|
flagSource := flag.NewSource(
|
|
// optionally enable reading of unset flags and their default
|
|
// values into config, defaults to false
|
|
IncludeUnset(true)
|
|
)
|
|
```
|
|
|
|
## Load Source
|
|
|
|
Load the source into config
|
|
|
|
```go
|
|
// Create new config
|
|
conf := config.NewConfig()
|
|
|
|
// Load flag source
|
|
conf.Load(flagSource)
|
|
```
