func Load ¶

func Load(ctx context.Context, pkgdir string, f func(*exec.Cmd) error) error

func LoadPkg ¶

func LoadPkg(ctx context.Context, pkgdir, pkgname string, scope *types.Scope, f func(*exec.Cmd) error) error

func LoadTargets ¶

func LoadTargets(ctx context.Context, pkgdir, pkgname string, targets []string, f func(*exec.Cmd) error) error

func Run ¶

func Run(ctx context.Context, pkgdir string, args ...string) error

Run uses Load to load the Go package in the given directory and turn it into an executable binary. It then runs the program as:

PROG [-v] CWD TMPFILE ARGS...

where CWD is the current working directory, TMPFILE is the name of a temporary file where the program sends its output, and ARGS are the additional arguments passed to Run.

Run parses the output in the temporary file: a JSON-encoded list of error strings. If the list is empty, Run returns nil. Otherwise it converts those strings to an error (using multierr.Combine if there are two or more) and returns it.
