FAQPage Schema

How do I add a new Cobra command with JSON output in Golang?▼

You scaffold a new Cobra command file at pkg/cmd/<command>.go, wire it into rootCmd, and generate tests. The scaffolding includes Use, Short, Long, Args, PreRunE, RunE fields, flag binding with *Var variants, JSON-mode output, and test scaffolding for execution paths.

How do I scaffold a CLI command file and wire it into the root command?▼

Scaffolding a CLI command file creates the file at pkg/cmd/<command>.go and wires it into rootCmd for discovery. This ensures the new command is properly registered while generating tests that exercise both standard and JSON outputs.

What is the required structure for a Cobra-based command with flag binding?▼

The required structure for a Cobra-based command includes Use, Short, Long, Args, PreRunE, and RunE sections. It also implements flag binding with *Var variants and supports JSON-mode output alongside optional text output for progress logging.

How do I generate tests for a Cobra command's JSON and standard output?▼

Test scaffolding for a Cobra command generates cases that exercise both standard and JSON outputs. This verifies the preRun and execution paths function correctly when handling flag binding and JSON-mode output.

Can I add optional text output for progress logging alongside JSON output?▼

Yes, command scaffolding supports both JSON-mode output and optional text output. This allows you to generate JSON for structured data while using text output for progress logging and error handling.
