To Show extra information

python -m toisan_lang "你系嚿叉烧。你个头系假咯。睇下你系乜呀。睇下（丐时）系乜。" --show tree code

Output:

Parse Tree:
(START
  (begin_program (begin_scope))
  (block
    (statement (st_assign
      (var_list (var (variable_ref '你'))) '系'
      (exp_list (exp (dict_init '嚿叉烧'))))) '。'
    (statement (st_assign
      (var_list (var (variable_ref '你' '个' '头'))) '系'
      (exp_list (exp (constant (boolean '假')))))) '咯' '。'
    (statement (st_print '睇下'
      (var (variable_ref '你')) '系乜')) '呀' '。'
    (statement (st_print '睇下'
      (adjusted_exp '（'
        (exp (now '丐时')) '）') '系乜')) '。')
  (end_program (end_scope)))

Transpiled Python Code:
from datetime import datetime

def main():
    你 = dict()
    你['头'] = False
    print( 你 )
    print( ( datetime.now() ) )

if __name__ == '__main__':
    main()

{'头': False}
