 10.9.3 Pretty-Printer Commands
 ------------------------------
 
 'info pretty-printer [OBJECT-REGEXP [NAME-REGEXP]]'
      Print the list of installed pretty-printers.  This includes
      disabled pretty-printers, which are marked as such.
 
      OBJECT-REGEXP is a regular expression matching the objects whose
      pretty-printers to list.  Objects can be 'global', the program
      space's file (Progspaces In Python), and the object files
DONTPRINTYET       within that program space (Objfiles In Python).  *NoteDONTPRINTYET       within that program space (Objfiles In Python).  
      Selecting Pretty-Printers, for details on how GDB looks up a
      printer from these three objects.
 
      NAME-REGEXP is a regular expression matching the name of the
      printers to list.
 
 'disable pretty-printer [OBJECT-REGEXP [NAME-REGEXP]]'
      Disable pretty-printers matching OBJECT-REGEXP and NAME-REGEXP.  A
      disabled pretty-printer is not forgotten, it may be enabled again
      later.
 
 'enable pretty-printer [OBJECT-REGEXP [NAME-REGEXP]]'
      Enable pretty-printers matching OBJECT-REGEXP and NAME-REGEXP.
 
    Example:
 
    Suppose we have three pretty-printers installed: one from library1.so
 named 'foo' that prints objects of type 'foo', and another from
 library2.so named 'bar' that prints two types of objects, 'bar1' and
 'bar2'.
 
      (gdb) info pretty-printer
      library1.so:
        foo
      library2.so:
        bar
          bar1
          bar2
      (gdb) info pretty-printer library2
      library2.so:
        bar
          bar1
          bar2
      (gdb) disable pretty-printer library1
      1 printer disabled
      2 of 3 printers enabled
      (gdb) info pretty-printer
      library1.so:
        foo [disabled]
      library2.so:
        bar
          bar1
          bar2
      (gdb) disable pretty-printer library2 bar;bar1
      1 printer disabled
      1 of 3 printers enabled
      (gdb) info pretty-printer library2
      library1.so:
        foo [disabled]
      library2.so:
        bar
          bar1 [disabled]
          bar2
      (gdb) disable pretty-printer library2 bar
      1 printer disabled
      0 of 3 printers enabled
      (gdb) info pretty-printer library2
      library1.so:
        foo [disabled]
      library2.so:
        bar [disabled]
          bar1 [disabled]
          bar2
 
    Note that for 'bar' the entire printer can be disabled, as can each
 individual subprinter.
