Use of nested ternary expression in .zshrc prompt configuration

Question

what is wrong with my RPS1 expression

RPS1='%(t.[Ding!].%(t30.[Dong!].[%T]))'

Explanation:

I want to get [Ding!] if it is 11am, [Dong!] if it is 11:30am and if both is not true just normal time like [11:33]. But what is wrong?

Answer 1

The syntax is %[<number>](X.true.false), not %(X[<number>].true.false).

So:

RPS1='%(t.[Ding!].%30(t.[Dong!].[%T]))'
