set "app_root" from environment variables
BastiPaeltz opened this issue · comments
Hey,
I think it would be nice to be able to set the app_root
from environment variables like this:
app_root: "$GOPATH/src/$APP_PATH"
It should be pretty easy to implement this, there just would need to be a call to os.ExpandEnv(c.AppRoot)
at the end of the Load function. E.g.:
func (c *Configuration) Load(path string) error {
data, err := ioutil.ReadFile(path)
if err != nil {
return err
}
err = yaml.Unmarshal(data, c)
if err != nil {
return err
}
c.AppRoot = os.ExpandEnv(c.AppRoot)
return err
}
