Functions

func Run

func Run(c *Command) error

Run executes the gorram command.

Types

type Command

type Command struct {
	// Args contains the arguments to the function.
	Args []string
	// Package the function exists in.
	Package string
	// Function (or method) to call.
	Function string
	// GlobalVar, if not empty, indicates a global variable to call, and means
	// Function is a method on that variable.
	GlobalVar string
	// Regen, if true, indicates we should create a new script file even if the
	// old one exists.
	Regen bool
	// Cache, if non-empty, indicates the user has specified the non-default
	// location for their gorram scripts to be located.
	Cache string
	// Template, if non-empty, contains the Go template with which to format the
	// output.
	Template string
	// Env contains the input and output streams the command should read from
	// and write to.
	Env Env
	// contains filtered or unexported fields
}

Command contains the definition of a command that gorram can execute. It represents a package and either global function or a method call on a global variable. If GlobalVar is non-empty, it's the latter.

func (*Command) Generate

func (c *Command) Generate() (path string, err error)

Generate creates the gorram .go file for the given command.

type Env

type Env struct {
	Stderr io.Writer
	Stdout io.Writer
	Stdin  io.Reader
}

Env encapsulates the externalities of the environment in which a command is running.
