Types ¶
type CommandError ¶
CommandError represents an error that occurred during command execution. It wraps an underlying cause error and provides a user-friendly message. Implements cli.ExitCoder so urfave/cli can extract the exit code.
func (*CommandError) ExitCode ¶
func (e *CommandError) ExitCode() int
ExitCode returns the exit code for this error. If Code is explicitly set, it is returned. Otherwise defaults to ExitGeneral (1). Implements the cli.ExitCoder interface.
func (*CommandError) Unwrap ¶
func (e *CommandError) Unwrap() error
Unwrap returns the underlying cause error, enabling errors.Is and errors.As.
