示例1: Sub
func (s SubSubshell) Sub(scp *variables.Scope) (returnString string) {
logex.Debug("Substituting shell")
defer func() {
logex.Debugf("Returned '%s'", returnString)
}()
if _, isNoop := s.N.(NodeNoop); isNoop {
return ""
}
out := &bytes.Buffer{}
// Not sure if we need to capture this exit code for the $? var.
// Ignore it for now
_ = s.N.Eval(scp.Copy(), &T.IOContainer{&bytes.Buffer{}, out, os.Stderr})
return strings.TrimRight(out.String(), "\n")
}示例2: Eval
func (n NodePipe) Eval(scp *variables.Scope, ioc *T.IOContainer) T.ExitStatus {
lastPipeReader, pipeWriter := io.Pipe()
scp = scp.Copy()
cmd := n.Commands[0]
go cmd.Eval(scp, &T.IOContainer{In: &bytes.Buffer{}, Out: pipeWriter, Err: ioc.Err})
for _, cmd = range n.Commands[1 : len(n.Commands)-1] {
pipeReader, pipeWriter := io.Pipe()
go cmd.Eval(scp, &T.IOContainer{In: lastPipeReader, Out: pipeWriter, Err: ioc.Err})
