annotate lisp/gpm.el @ 5864:750fab17b299
Make #'parse-integer Lisp-visible, extend it, allowing non-ASCII digits.
src/ChangeLog addition:
2015-02-25 Aidan Kehoe <kehoea@parhasard.net>
* lread.c (read_atom): Use the new calling convention for
parse_integer().
* lisp.h: Change the declaration of parse_integer ().
* number.h (bignum_set_emacs_int, make_bignum_emacs_uint):
New #defines, used in data.c.
* lread.c (read_integer): Ditto.
* lread.c (read1): Ditto.
* data.c (find_highest_value): New.
* data.c (fill_ichar_array): New.
* data.c (build_fixnum_to_char_map): New.
* data.c (Fset_digit_fixnum_map): New.
* data.c (Fdigit_char_p): Moved from cl-extra.el.
* data.c (Fdigit_char): Moved from cl-extra.el.
* data.c (parse_integer): Moved from lread.c.
* data.c (Fparse_integer): Made available to Lisp.
* data.c (syms_of_data): Make the new subrs available.
* data.c (vars_of_data): Make the new vars available.
Expose parse_integer to Lisp, make it follow the Common Lisp API
(with some extensions, to allow us to support non ASCII digit
characters).
lisp/ChangeLog addition:
2015-02-25 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (digit-char-p): Moved to data.c.
* cl-extra.el (digit-char): Moved to data.c.
tests/ChangeLog addition:
2015-02-25 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
parse_integer(), used in #'read, now signals invalid-argument
rather than invalid-read-syntax, check for that.
* automated/lisp-tests.el:
Check #'parse-integer now it's available to Lisp, check
#'digit-char, #'digit-char-p and the congruence in behaviour,
check the XEmacs-specific RADIX-TABLE argument behaviour.
