envconfig Feature Request: Continue processing after missing required values

Feature Request: Continue processing after missing required values

Open hbobenicio opened this issue 5 years ago • 4 comments

With this spec...

type spec struct {
	Foo string `required:"true"`
	Bar string `required:"true"`
}

This process...

var s spec
err := envconfig.Process("myapp", &s)
if err != nil {
	log.Fatalln(err.Error())
}

...stops processing right after the first missing required variable is detected

2019/03/13 10:42:54 required key MYAPP_FOO missing value

Feature Request

It would be really useful in some cases (most? all of them?) just to keep processing, in order to detect all missing required variables.

Motivation

Just imagine an app that have a bunch of required variables that won't start because a missing required variable. Then you fix that one that is missing, then run the app again... then fix another one, then run it again... over and over, until you finally realize all the ones that are missing on your runtime configuration (just after some laborious run-and-fix work).
