Hi again Yuan:

I found another indentation issue in if-else conditions without
parenthesis:

if (pid == 0)
   print "hello from the child"
   else
   print "hello from the parent"


The else is not indented properly:

This is the explore output:

(translation_unit
 (if_statement if
  condition: 
   (parenthesized_expression (
    (binary_expression left: (identifier) operator: == right: (number_literal))
    ))
  consequence: 
   (expression_statement
    (concatenated_string (identifier)
     (string_literal " (string_content) ")
     (identifier) (identifier)
     (string_literal " (string_content) "))
    ;)))


Best,
Ergus
