From 1232ab31c656b8564984a758957466f90ac10501 Mon Sep 17 00:00:00 2001 From: Mattias Engdegård Date: Sun, 10 Mar 2024 13:18:22 +0100 Subject: Add `value<` (bug#69709) It's a general-purpose polymorphic ordering function, like `<` but for any two values of the same type. * src/data.c (syms_of_data): Add the `type-mismatch` error. (bits_word_to_host_endian): Move... * src/lisp.h (bits_word_to_host_endian): ...here, and declare inline. * src/fns.c (Fstring_lessp): Extract the bulk of this function to... (string_cmp): ...this 3-way comparison function, for use elsewhere. (bool_vector_cmp, value_cmp, Fvaluelt): New. * lisp/emacs-lisp/byte-opt.el (side-effect-free-fns, pure-fns): Add `value<`, which is pure and side-effect-free. * test/src/fns-tests.el (fns-value<-ordered, fns-value<-unordered) (fns-value<-type-mismatch, fns-value<-symbol-with-pos) (fns-value<-circle, ert-deftest fns-value<-bool-vector): New tests. * doc/lispref/sequences.texi (Sequence Functions): * doc/lispref/numbers.texi (Comparison of Numbers): * doc/lispref/strings.texi (Text Comparison): Document the new value< function. * etc/NEWS: Announce. --- lisp/emacs-lisp/byte-opt.el | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lisp/emacs-lisp/byte-opt.el') diff --git a/lisp/emacs-lisp/byte-opt.el b/lisp/emacs-lisp/byte-opt.el index 54997205edb..ea163723a3e 100644 --- a/lisp/emacs-lisp/byte-opt.el +++ b/lisp/emacs-lisp/byte-opt.el @@ -1772,7 +1772,7 @@ See Info node `(elisp) Integer Basics'." string-version-lessp substring substring-no-properties sxhash-eq sxhash-eql sxhash-equal sxhash-equal-including-properties - take vconcat + take value< vconcat ;; frame.c frame-ancestor-p frame-bottom-divider-width frame-char-height frame-char-width frame-child-frame-border-width frame-focus @@ -1973,7 +1973,7 @@ See Info node `(elisp) Integer Basics'." hash-table-p identity length length< length= length> member memq memql nth nthcdr proper-list-p rassoc rassq safe-length string-bytes string-distance string-equal string-lessp - string-search string-version-lessp take + string-search string-version-lessp take value< ;; search.c regexp-quote ;; syntax.c -- cgit v1.2.3
