Functions ¶
func Parse ¶
Parse goes though all the keys stored in viper config and parses them with golang's internal templating engine.
Example ¶
package main import ( "bytes" "fmt" "github.com/molecule-man/vipertpl" "github.com/spf13/viper" ) func main() { input := []byte(` foo: 'foo_val' bar: 'bar_val + {{ ViperGet "foo" }}' `) viper.SetConfigType("yaml") err := viper.ReadConfig(bytes.NewBuffer(input)) if err != nil { panic(err) } err = vipertpl.Parse(viper.GetViper()) if err != nil { panic(err) } fmt.Printf("%#v", viper.Get("bar")) }
Output: "bar_val + foo_val"
