示例1: Eval
func (n NodeCommand) Eval(scp *variables.Scope, ioc *T.IOContainer) T.ExitStatus {
// A line with only assignments applies them to the Root Scope
// We check this first to avoid unnecessary scope Push/Pop's
if len(n.Args) == 0 {
for k, v := range n.Assign {
scp.Set(k, v.Expand(scp))
}
return T.ExitSuccess
}
// Minimum of len(n.Args) after expansions, Likely
// that it will be more after globbing though
expandedArgs := []string{}
for _, arg := range n.Args {
expandedArgs = append(expandedArgs, arg.Expand(scp))
}
// Order of precedence:
// Relative command > Builtin > User Function > Other external command
command := expandedArgs[0]
builtinFunc, builtinFound := builtins.All[command]
userFunc, userFuncFound := scp.Functions[command]
if strings.ContainsRune(command, '/') || (!builtinFound && !userFuncFound) {
scp.Push()
defer scp.Pop()
for k, v := range n.Assign {
