示例1: Eval
func (v *evalOutput) Eval(s ast.Scope, stack *ast.Stack) (interface{}, ast.Type, error) {
// The expressions should all be on the stack in reverse
// order. So pop them off, reverse their order, and concatenate.
nodes := make([]*ast.LiteralNode, 0, len(v.Exprs))
for range v.Exprs {
nodes = append(nodes, stack.Pop().(*ast.LiteralNode))
}
// Special case the single list and map
if len(nodes) == 1 {
switch t := nodes[0].Typex; t {
case ast.TypeList:
fallthrough
case ast.TypeMap:
fallthrough
case ast.TypeUnknown:
return nodes[0].Value, t, nil
}
}
// Otherwise concatenate the strings
var buf bytes.Buffer
for i := len(nodes) - 1; i >= 0; i-- {
buf.WriteString(nodes[i].Value.(string))
}
return buf.String(), ast.TypeString, nil
}示例2: Eval
func (v *evalConcat) Eval(s ast.Scope, stack *ast.Stack) (interface{}, ast.Type, error) {
// The expressions should all be on the stack in reverse
// order. So pop them off, reverse their order, and concatenate.
nodes := make([]*ast.LiteralNode, 0, len(v.Exprs))
for range v.Exprs {
nodes = append(nodes, stack.Pop().(*ast.LiteralNode))
}
var buf bytes.Buffer
for i := len(nodes) - 1; i >= 0; i-- {
buf.WriteString(nodes[i].Value.(string))
}
return buf.String(), ast.TypeString, nil
