=======

|
|
|
||
|
|
Configure your Go application from the environment.
|
||
|
|
|
||
|
|
Supports most basic Go types and works nicely with the built in `flag` package.
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import(
|
||
|
|
"flag"
|
||
|
|
"fmt"
|
||
|
|
. "github.com/ian-kent/envconf"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
count := flag.Int("count", FromEnvP("COUNT", 15).(int), "Count target")
|
||
|
|
flag.Parse()
|
||
|
|
for i := 1; i <= *count; i++ {
|
||
|
|
fmt.Printf("%d\n", i)
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
