Overview ¶
Package bootstrap performs initial setup of the environment. Create a new `*env.Environment` and then pass it to `Into`.

Functions ¶
func DevNull ¶
func DevNull(e *env.Environment)
DevNull binds *in*, *out*, and *err* to the operating system's bit bucket device (usually /dev/null)
func DevNullEnvironment ¶
func DevNullEnvironment() *env.Environment
DevNullEnvironment configures a bootstrapped environment completely isolated from the top-level of the system. All I/O is rerouted to and from the operating system's bit bucket device (usually /dev/null)
func Into ¶
func Into(e *env.Environment)
Into sets up initial built-ins and assets. This call is useful if you're wiring up your own Environments. Otherwise, calls to TopLevelEnvironment and DevNullEnvironment will perform this action for you.
func ProcessArgs ¶
func ProcessArgs(e *env.Environment)
ProcessArgs binds *args* to the current Go app's command line arguments
func ProcessEnv ¶
func ProcessEnv(e *env.Environment)
ProcessEnv binds *env* to the operating system's environment variables
func StandardIO ¶
func StandardIO(e *env.Environment)
StandardIO binds *in*, *out*, and *err* to the operating system's standard input and output facilities
func TopLevelEnvironment ¶
func TopLevelEnvironment() *env.Environment
TopLevelEnvironment configures an environment that could be used at the top-level of the system, such as the REPL. It has access to the *env*, *args*, and operating system's standard in/out/err file streams.
