Summary

0001891: #install_printer

Description

Full_Name: Winfried Dreckmann
Version: 3.07-1
OS: Linux PowerPC
Submission from: t3o902p168.telia.com (81.225.156.168)

(1) The #install_printer directive does not recognize modules created in the
toplevel, for instance:

# module Test = struct
let my_printer f x = Format.fprintf f "%x" x
end;;
module Test : sig val my_printer : Format.formatter -> int -> unit end
# Test.my_printer;;
- : Format.formatter -> int -> unit = <fun>
# #install_printer Test.my_printer;;
Reference to undefined global `Test'

I remember that this worked in earlier versions of OCaml.

(2) The #install_printer directive also causes trouble if applied to C
externals. The following happens with a function "Printtest.my_printer" written
in C and
used in a customized toplevel:

# #install_printer Printtest.my_printer;;
# "abcde";;
Speicherzugriffsfehler

The C function in this example simply calls "Format.pp_print_string". I am not
sure if C externals are allowed to be printers. I send details if necessary.

Regards,
Winfried Dreckmann

Notes
(0000185) administrator (administrator) 2004-02-15 12:09	(1) fixed 2004-02-15 by XL. (2) it's true that #install_printer currently doesn't support printers that are declared "external". This doesn't seem too limiting in practice, so I'll leave it as feature wish rather than as a bug. -XL

(0006818) doligez (manager) 2012-01-27 09:33	There doesn't seem to be much demand for this feature, but if someone provides a good patch, we are willing to consider including it.

(0006826) lefessan (developer) 2012-01-27 14:09	(1) is already fixed. (2) would need to be tested.
