From 9613690f6e51e2f2aa2bcbbede3e209d08cfaaad Mon Sep 17 00:00:00 2001 From: Philipp Stephani Date: Tue, 3 Oct 2017 16:14:54 +0200 Subject: Raise an error when detecting old-style backquotes. They have been deprecated for a decade now. * src/lread.c (Fload): Don't use record_unwind_protect to warn about old-style backquotes any more. They now generate a hard error. (read1): Signal an error when detecting old-style backquotes. Remove unused label. (syms_of_lread): Remove unused internal variable 'lread--old-style-backquotes'. (load_error_old_style_backquotes): Rename from 'load_warn_oldstyle_backquotes'. Signal an error. * lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Remove check from byte compiler. It isn't triggered any more. * test/src/lread-tests.el (lread-tests--old-style-backquotes): Adapt unit test. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--old-style-backquotes) (bytecomp-tests-function-put): Adapt unit tests. * etc/NEWS: Document change. --- lisp/emacs-lisp/bytecomp.el | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) (limited to 'lisp/emacs-lisp/bytecomp.el') diff --git a/lisp/emacs-lisp/bytecomp.el b/lisp/emacs-lisp/bytecomp.el index 590db570c56..45fa188d6c8 100644 --- a/lisp/emacs-lisp/bytecomp.el +++ b/lisp/emacs-lisp/bytecomp.el @@ -2048,14 +2048,8 @@ With argument ARG, insert value in current buffer after the form."
