Question

It seems that if I put code in my ternary evaluation it fails, but placing true or false it works.

Here is my code:

>test = [nil]
=> [nil]

>test.any? ? puts "AAA" : puts "BBB"
SyntaxError: (irb):16: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
test.any? ? puts "AAA" : puts "BBB"
                  ^
(irb):16: syntax error, unexpected ':', expecting $end
test.any? ? puts "AAA" : puts "BBB"

>test.any? ? true : false
=> false

>test << 1
=> [nil, 1]

>test.any? ? true : false
=> true


>test.any? ? puts "AAA" : puts "BBB"
SyntaxError: (irb):14: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
test.any? ? puts "AAA" : puts "BBB"
                  ^
(irb):14: syntax error, unexpected ':', expecting $end
test.any? ? puts "AAA" : puts "BBB"
                        ^

You need parentheses.

>> test.any? ? puts("AAA") : puts("BBB")
BBB
=> nil

You should avoid parentheseless call in inline functions.
