type Command ¶

type Command interface {
	// Get executes 'go get' with args.
	Get(ctx context.Context, args ...string) error
	// Build executes 'go build' with args.
	Build(ctx context.Context, args ...string) error
	// ModTidy executes 'go mod tidy'.
	ModTidy(ctx context.Context) error
	// ModDownload executes 'go mod download'
	ModDownload(ctx context.Context) error
	// List executes 'go list' with args.
	// The result is represents as an io.Reader.
	List(ctx context.Context, args ...string) (io.Reader, error)
	// Env executes 'go env' with args
	// The resutl is represents as an io.Reder.
	Env(ctx context.Context, args ...string) (io.Reader, error)
}

Command provides available Go commands. Each comamnd may return these errors:

• *TimeoutErr: comamnd timed out
• context.Canceled: context is canceled
• others: command execution error

func New() Command

type CommandMock ¶
