[PATCH] Conditionalise `old-eq', `old-equal' etc. at compile time.
13 years, 1 month
Aidan Kehoe
Aidan Kehoe
As I said a few months ago, nothing in our code base provokes the ebola
warnings any more (though I think I should have pointed Andreas Roehler to
them at some point, he seemed to be affected by char-int confoundance in
code he had originally written for GNU Emacs). I’d like to remove thes
functions and their byte codes at some point in the future, and this is one
step towards that.

primitive types. (This change was necessary in order for ＠sc{mule},
i.e. Asian-language, support to be correctly implemented.)
- Even in XEmacs version 20, remnants of the equivalence between
-characters and integers still exist; this is termed the ＠dfn{char-int
-confoundance disease}. In particular, many functions such as ＠code{eq},
-＠code{equal}, and ＠code{memq} have equivalent functions (＠code{old-eq},
-＠code{old-equal}, ＠code{old-memq}, etc.) that pretend like characters
-are integers are the same. Byte code compiled under any version 19
-Emacs will have all such functions mapped to their ＠code{old-} equivalents
-when the byte code is read into XEmacs 20. This is to preserve
-compatibility---Emacs 19 converts all constant characters to the equivalent
-integer during byte-compilation, and thus there is no other way to preserve
-byte-code compatibility even if the code has specifically been written
-with the distinction between characters and integers in mind.
-
Every character has an equivalent integer, called the ＠dfn{character
code}. For example, the character ＠kbd{A} is represented as the
＠w{integer 65}, following the standard ＠sc{ascii} representation of
＠＠ -2317,32 +2304,6 ＠＠
＠end defun
-＠defun old-eq object1 object2
-This function exists under XEmacs 20 and is exactly like ＠code{eq}
-except that it suffers from the char-int confoundance disease.
-In other words, it returns ＠code{t} if given a character and the
-equivalent integer, even though the objects are of different types!
-You should ＠emph{not} ever call this function explicitly in your
-code. However, be aware that all calls to ＠code{eq} in byte code
-compiled under version 19 map to ＠code{old-eq} in XEmacs 20.
-(Likewise for ＠code{old-equal}, ＠code{old-memq}, ＠code{old-member},
-＠code{old-assq} and ＠code{old-assoc}.)
-
-＠example
-＠group
-;; ＠r{Remember, this does not apply under XEmacs 19.}
-?A
- ＠result{} ?A
-(char-int ?A)
- ＠result{} 65
-(old-eq ?A 65)
- ＠result{} t ; ＠r{Eek, we've been infected.}
-(eq ?A 65)
- ＠result{} nil ; ＠r{We are still healthy.}
-＠end group
-＠end example
-＠end defun
-
＠defun eql object1 object2
This function returns ＠code{t} if the two arguments are the same object,

description:
Conditionalise the old-* functions and byte codes at compile time.
src/ChangeLog addition:
2011-03-15 Aidan Kehoe <kehoea(a)parhasard.net>
* config.h.in (SUPPORT_CONFOUNDING_FUNCTIONS): New #define,
equivalent NEED_TO_HANDLE_21_4_CODE by default, describing whether
this XEmacs should support the old-eq, old-equal and related
functions and byte codes.
* bytecode.c (UNUSED):
Only interpret old-eq, old-equal, old-memq if
SUPPORT_CONFOUNDING_FUNCTIONS is defined.
* data.c:
Move Fold_eq to fns.c with the rest of the Fold_* functions.
* fns.c:
* fns.c (Fmemq):
* fns.c (memq_no_quit):
* fns.c (assoc_no_quit):
* fns.c (Frassq):
* fns.c (Fequal):
* fns.c (Fold_equal):
* fns.c (syms_of_fns):
Group old-eq, old-equal, old-memq etc together, surround them with
#ifdef SUPPORT_CONFOUNDING_FUNCTIONS.
lisp/ChangeLog addition:
2011-03-15 Aidan Kehoe <kehoea(a)parhasard.net>
* bytecomp.el:
Don't generate the old-eq, old-memq, old-equal bytecodes any more,
but keep the information about them around for the sake of the
disassembler.
man/ChangeLog addition:
2011-03-15 Aidan Kehoe <kehoea(a)parhasard.net>
* lispref/objects.texi (Character Type):
* lispref/objects.texi (Equality Predicates):
No longer document `old-eq', `old-equal', they haven't been used
in years.
tests/ChangeLog addition:
2011-03-17 Aidan Kehoe <kehoea(a)parhasard.net>
* automated/lisp-tests.el:
Only test the various old-* function if old-eq is bound and a
subr.

the modern convention is followed, and characters are their own
primitive types. (This change was necessary in order for ＠sc{mule},
i.e. Asian-language, support to be correctly implemented.)
-
- Even in XEmacs version 20, remnants of the equivalence between
-characters and integers still exist; this is termed the ＠dfn{char-int
-confoundance disease}. In particular, many functions such as ＠code{eq},
-＠code{equal}, and ＠code{memq} have equivalent functions (＠code{old-eq},
-＠code{old-equal}, ＠code{old-memq}, etc.) that pretend like characters
-are integers are the same. Byte code compiled under any version 19
-Emacs will have all such functions mapped to their ＠code{old-} equivalents
-when the byte code is read into XEmacs 20. This is to preserve
-compatibility---Emacs 19 converts all constant characters to the equivalent
-integer during byte-compilation, and thus there is no other way to preserve
-byte-code compatibility even if the code has specifically been written
-with the distinction between characters and integers in mind.
Every character has an equivalent integer, called the ＠dfn{character
code}. For example, the character ＠kbd{A} is represented as the
＠＠ -2317,32 +2304,6 ＠＠
＠end defun
-＠defun old-eq object1 object2
-This function exists under XEmacs 20 and is exactly like ＠code{eq}
-except that it suffers from the char-int confoundance disease.
-In other words, it returns ＠code{t} if given a character and the
-equivalent integer, even though the objects are of different types!
-You should ＠emph{not} ever call this function explicitly in your
-code. However, be aware that all calls to ＠code{eq} in byte code
-compiled under version 19 map to ＠code{old-eq} in XEmacs 20.
-(Likewise for ＠code{old-equal}, ＠code{old-memq}, ＠code{old-member},
-＠code{old-assq} and ＠code{old-assoc}.)

[COMMIT] Update sudoku to work with more recent versions of the byte compiler
13 years, 1 month

Aidan Kehoe
APPROVE COMMIT
NOTE: This patch has been committed.
xemacs-packages/games/ChangeLog addition:
2011-03-17 Aidan Kehoe <kehoea(a)parhasard.net>
* sudoku.el:
* sudoku.el (sudoku-mode-setup-modeline):
* sudoku.el (sudoku-autoinsert):
* sudoku.el (sudoku-pencil-mode):
* sudoku.el (sudoku-download-puzzle):
* sudoku.el (sudoku-print):
* sudoku.el (sudoku-sdk-file-p):
* sudoku.el (sudoku-string-to-board):
* sudoku.el (sudoku-builtin-puzzles): Moved.
Update this file to work better with more recent versions of XEmacs.
This involves:
-- modeline-multibyte-status -> modeline-coding-system
-- Using unquoted symbols in `block' and `return-from', as always
documented but only recently forced.
-- Use #'signum, not #'positivep (the latter is not in any
standard and was never built-in to XEmacs.
-- Mark various special symbols used by the code as such.

[PATCH] Add min-colors specifier to defface
13 years, 1 month
Jeff Sparkes
Jeff Sparkes
Emacs has an extra specifier to defface, min-colors, which allows you to
use
different settings based on the number of colors that can be displayed on a
device.
http://www.gnu.org/software/emacs/elisp/html_node/Defining-Faces.html
<http://www.gnu.org/software/emacs/elisp/html_node/Defining-Faces.html>It
has been showing up in customize-based themes, so I thought I'd make
them load in XEmacs as well. An example theme is at
http://git.savannah.gnu.org/cgit/emacs.git/tree/etc/themes/tango-theme.el
