annotate lib-src/add-big-package.sh @ 4678:b5e1d4f6b66f
Make #'floor, #'ceiling, #'round, #'truncate conform to Common Lisp.
lisp/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (ceiling*, floor*, round*, truncate*):
Implement these in terms of the C functions; mark them as
obsolete.
(mod*, rem*): Use #'nth-value with the C functions, not #'nth with
the CL emulation functions.
man/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* lispref/numbers.texi (Bigfloat Basics):
Correct this documentation (ignoring for the moment that it breaks
off in mid-sentence).
tests/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test the new Common Lisp-compatible rounding functions available in
C.
(generate-rounding-output): Provide a function useful for
generating the data for the rounding functions tests.
src/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* floatfns.c (ROUNDING_CONVERT, CONVERT_WITH_NUMBER_TYPES)
(CONVERT_WITHOUT_NUMBER_TYPES, MAYBE_TWO_ARGS_BIGNUM)
(MAYBE_ONE_ARG_BIGNUM, MAYBE_TWO_ARGS_RATIO)
(MAYBE_ONE_ARG_RATIO, MAYBE_TWO_ARGS_BIGFLOAT)
(MAYBE_ONE_ARG_BIGFLOAT, MAYBE_EFF, MAYBE_CHAR_OR_MARKER):
New macros, used in the implementation of the rounding functions.
(ceiling_two_fixnum, ceiling_two_bignum, ceiling_two_ratio)
(ceiling_two_bigfloat, ceiling_one_ratio, ceiling_one_bigfloat)
(ceiling_two_float, ceiling_one_float, ceiling_one_mundane_arg)
(floor_two_fixnum, floor_two_bignum, floor_two_ratio)
(floor_two_bigfloat, floor_one_ratio, floor_one_bigfloat)
(floor_two_float, floor_one_mundane_arg, round_two_fixnum)
(round_two_bignum_1, round_two_bignum, round_two_ratio)
(round_one_bigfloat_1, round_two_bigfloat, round_one_ratio)
(round_one_bigfloat, round_two_float, round_one_float)
(round_one_mundane_arg, truncate_two_fixnum)
(truncate_two_bignum, truncate_two_ratio, truncate_two_bigfloat)
(truncate_one_ratio, truncate_one_bigfloat, truncate_two_float)
(truncate_one_float, truncate_one_mundane_arg):
New functions, used in the implementation of the rounding
functions.
(Fceiling, Ffloor, Fround, Ftruncate, Ffceiling, Fffloor)
(Ffround, Fftruncate):
Revise to fully support Common Lisp conventions. This means:
-- All functions have optional DIVISOR arguments
-- All functions return multiple values; see #'values
-- All functions do their arithmetic with the correct number types
according to the contamination rules.
-- #'round and #'fround always round towards the even number
in ambiguous cases.
* doprnt.c (emacs_doprnt_1):
* number.c (internal_coerce_number):
Call Ftruncate with two arguments, not one.
* floatfns.c (Ffloat):
Correct this, if NUMBER is a bignum.
* lisp.h:
Declare Ftruncate as taking two arguments.
* number.c:
Provide scratch_ratio2, init it appropriately.
* number.h:
Make scratch_ratio2 available.
* number.h (BIGFLOAT_ARITH_RETURN):
* number.h (BIGFLOAT_ARITH_RETURN1):
Correct these functions.

| 26 ### Commentary: | |
| 27 | |
| 28 ## This file copies a single lisp file into an XEmacs package hierarchy and | |
| 29 ## performs the necessary magic so that it will be autoloaded at the next | |
| 30 ## dump. | |
| 31 | |
| 32 ## Parameters: | |
| 33 ## $1 -- Full path to an XEmacsen later than 20.3 | |
| 34 ## $2 -- Full path to a lisp package tarball to install | |
| 35 ## $3 -- Full path to a lisp directory in an XEmacs package hierarchy | |
| 36 ## This directory will be created if it does not exist. | |
| 37 ## NOTE: the directory name should *not* end in a trailing slash | |
| 38 | |
| 39 | |
| 40 ### Code: | |
| 41 | |
| 42 XEMACS="$1" # Not used at present | |
| 43 LISP_FILE="$2" # Should be a binary package tarball | |
| 44 DEST_DIR="$3" # Should be a top level package directory | |
| 45 | |
| 46 # Test for valid XEmacs executable and valid input file | |
| 47 if [ ! -f "${LISP_FILE}" -o ! -x "${XEMACS}" ]; then | |
| 48 exit 1 | |
| 49 fi | |
| 50 | |
| 51 # Test for destination directory, creating if necessary | |
| 52 test -d "${DEST_DIR}" || mkdir "${DEST_DIR}" | |
| 53 test -d "${DEST_DIR}" || exit 1; | |
| 54 | |
| 55 # Very simple minded extraction for the first cut | |
| 56 # We'll get more sophisticated later | |
| 57 cd "${DEST_DIR}" | |
| 58 gunzip -c "${LISP_FILE}" | tar xvf - | |
| 59 | |
| 60 # Need to refresh the info/dir file, I don't know how to do that. | |
