A better way to parse a different source?

[iancullinane]

I am using kong to parse inputs from a chat bot for chat ops purposes. Everything has been very well except for it to work for me I added one small change which doesn't feel right. In global.go I added the following function:

func ParseFromArgs(cli interface{}, args []string, options ...Option) (*Context, error) {
	parser, err := New(cli, options...)
	if err != nil {
		log.Println(err)
	}
	ctx, err := parser.Parse(args[1:])
	if err != nil {
		return nil, err
	}
	// parser.FatalIfErrorf(err)
	return ctx, nil
}

So instead of calling the usual Parse function which is coded to read from os.Args I pass in whatever. Is there a cleaner way to do this or has this use-case been brought up before?

Using New+Parse is the recommended way to do this, as you have. You can call New once, then call Parse repeatedly.

Also maybe check out the examples folder, it has a server that would be a good base to look at.
