hi,

i'm trying to use the pretty printer but i have a lot of troubles with it !


* (pprint-logical-block (nil '(nil))
        (write-char #\1)
        (pprint-indent :current 1)
        (pprint-newline :mandatory)
        (pprint-logical-block (nil '(nil))
         (write-char #\2) 
         (pprint-indent :current 1)
         (pprint-newline :mandatory)
         (pprint-logical-block (nil '(nil))
          (write-char #\3) 
          (pprint-indent :current 1)
          (pprint-newline :mandatory)
          (write-string "hello !")
          (pprint-indent :current 1)
          (pprint-newline :mandatory)
          (write-string "world !")
          (pprint-indent :block 0)
          (pprint-newline :mandatory)      
          (write-char #\3) )
         (pprint-indent :block 0)
         (pprint-newline :mandatory)      
         (write-char #\2) )
        (pprint-indent :block 0)
        (pprint-newline :mandatory)      
        (write-char #\1) )


here with cmucl18e and corman lisp seems to work good.
1
  2
    3
      hello !
              world !
    3
  2
1NIL


with clisp 2.31 i have indentation trouble :

1 
  2 
    3 
      hello ! 
              world !
              3
    2
  1


clisp implementation notes does not say anything about this ...

does clisp use XP printer ?

Are implementations around have troubles with prettyprint or is it just a local problem ?


ctu.

As far as I know, it's a CLISP problem.  I sent a bug report a few
months ago but the bug is still present in the 2.33.2 version.
