Provide %b in #'format; use it for converting between ints and bit vectors.
lisp/ChangeLog addition:
2007-12-17 Aidan Kehoe <kehoea@parhasard.net>
* subr.el (integer-to-bit-vector): New.
* subr.el (bit-vector-to-integer): New.
Provide naive implementations using the Lisp reader for these.
src/ChangeLog addition:
2007-12-17 Aidan Kehoe <kehoea@parhasard.net>
* doprnt.c (emacs_doprnt_1):
Add support for formatted printing of both longs and bignums as
base 2.
* editfns.c (Fformat):
Document the new %b escape for #'format.
* lisp.h:
Make ulong_to_bit_string available beside long_to_string.
* lread.c:
Fix a bug where the integer base was being ignored in certain
contexts; thank you Sebastian Freundt. This is necessary for
correct behaviour of #'integer-to-bit-vector and
#'bit-vector-to-integer, just added to subr.el
* print.c (ulong_to_bit_string): New.
Analagous to long_to_string, but used all the time when %b is
encountered, since we can't pass that to sprintf.
man/ChangeLog addition:
2007-12-17 Aidan Kehoe <kehoea@parhasard.net>
* lispref/strings.texi (Formatting Strings):
Document %b for binary output.
