Run go generate to execute commands defined in //go:generate comments within your Go source files.
Use go generate to run commands specified in //go:generate comments within your Go source files. Add a comment like //go:generate go run gen.go above your package declaration, then execute the command:
go generate
This command scans the current directory and subdirectories for //go:generate directives and executes them in order.
The go generate command automates repetitive tasks like creating boilerplate code or documentation by running instructions you write directly in your code comments. Think of it as a built-in script runner that looks for special notes in your files and executes the commands listed there. You use it to keep your project files synchronized without manually running separate scripts.
