if err := o.Set(k, a); err != nil {
fmt.Printf("error: %#v\n", err)
}
if err := printer.Fprint(os.Stdout, o.Node()); err != nil {
fmt.Printf("error: %#v\n", err)
}
Output: { local foo = alpha.beta.charlie('arg1'), }

if err := o.Set(k, t); err != nil {
fmt.Printf("error: %#v\n", err)
}
if err := printer.Fprint(os.Stdout, o.Node()); err != nil {
fmt.Printf("error: %#v\n", err)
}
Output: { foo: ['hello'], }
type Binary ¶

type Conditional ¶
Conditional represents a conditional
Example ¶
o := NewObject()
k := NewKey("foo")
cond := NewBinary(
NewVar("alpha"),
NewVar("beta"),
BopEqual,
)
trueBranch := NewObject()
trueBranch.Set(
NewKey(
"foo",
KeyOptCategory(ast.ObjectFieldID),
KeyOptVisibility(ast.ObjectFieldInherit)),
NewStringDouble("1"),
)
falseBranch := NewObject()
falseBranch.Set(
NewKey(
"foo",
KeyOptCategory(ast.ObjectFieldID),
KeyOptVisibility(ast.ObjectFieldInherit)),
NewStringDouble("2"),
)
c := NewConditional(cond, trueBranch, falseBranch)
if err := o.Set(k, c); err != nil {
fmt.Printf("error: %#v\n", err)
}
if err := printer.Fprint(os.Stdout, o.Node()); err != nil {
fmt.Printf("error: %#v\n", err)
}
Output: { foo:: if alpha == beta then { foo: '1', } else { foo: '2', }, }
