Cobra has two types of flags: Persistent flags - available to the command it is assigned to, as well as all its sub-commands Local flags - only assigned to a specific command Our example is small enough that this distinction does not have a real impact. // See the License for the specific language governing permissions and, "Calling command without subcommands should not have error: %v", `invalid command returned from ExecuteC: expected "child"', got: %q`, "Command %q must have context when called with ExecuteContext", "Command %s must have background context". the version template.

I have an approach to check if a flag is set using reflect: Thanks for contributing an answer to Stack Overflow! # to enable it.

How to check for #1 being either `d` or `h` with latex3? If the computed value depends on other flags or is expensive to calculate, then use the approach suggested in one of the other answers.

I'm using cobra to build a CLI and want to simulate a command being run with different sets of options/flags. The error can then be caught at the execute function call. Command is the central point of the application. Viper. The *cobra.Command have RUN which is a func and takes the pointer of *cobra.Command and a slice of string []string.
