parsers
=======
This directory contains pre-built, custom parsers that can be used with `env.ParseWithFuncs`
to facilitate the parsing of envs that are not basic types.
Example Usage:
```golang
package main
import (
"fmt"
"log"
"net/url"
"github.com/caarlos0/env"
"github.com/caarlos0/env/parsers"
)
type config struct {
ExampleURL url.URL `env:"EXAMPLE_URL" envDefault:"https://google.com"`
}
func main() {
cfg := config{}
if err := env.ParseWithFuncs(&cfg, env.CustomParsers{
parsers.URLType: parsers.URLFunc,
}); err != nil {
log.Fatal("Unable to parse envs: ", err)
}
fmt.Printf("Scheme: %v Host: %v\n", cfg.ExampleURL.Scheme, cfg.ExampleURL.Host)
}
```
