go-getoptions v0.18.0 Release Notes

Release Date: 2020-03-25 // about 4 years ago

  • 🚀 As the releases before, this release has 100% test coverage.

    🚀 This release adds initial support for Environment Variables and adds lots of GoDoc examples.

    🆕 New Features

    • 🎉 Initial support for environment variables has been added.

    👍 Currently, only opt.String and opt.StringVar are supported.

    To use it, set the option modify function to opt.GetEnv.
    For example:

    var profile stringopt.StringVar(&profile, "profile", "default", opt.GetEnv("AWS\_PROFILE"))

    Or:

    profile := opt.String("profile", "default", opt.GetEnv("AWS\_PROFILE"))

    👍 NOTE: Non supported option types behave with a No-Op when opt.GetEnv is defined.

    Minor changes

    • 🔄 Change opt.Dispatch signature to clarify the actual use of the variable.
      ➕ Additionally, actually use the variable, before it was hardcoded to "help".

      -func (gopt *GetOpt) Dispatch(ctx context.Context, helpOptionName string, args []string) error+func (gopt *GetOpt) Dispatch(ctx context.Context, helpCommandName string, args []string) error
