Functions

func ExitCodeFrom

func ExitCodeFrom(err error) int

ExitCodeFrom extracts the shell exit status from a shell execution error. It returns the exit code when err wraps an interp.ExitStatus, or 0 for any other error.

func Run

func Run(ctx context.Context, prog *Program, streams *Streams) error

Run parses and executes the shell program described by prog, writing output to the provided streams. It returns an [error] if the source cannot be parsed or if the program exits with a non-zero status.

Types

type Program

type Program struct {
	Name string
	Dir  string
	Src  string
}

Program holds the source and execution context for a shell program to be interpreted.

type Streams struct {
	Stdout io.Writer
	Stderr io.Writer
}
