* doc/emacs/building.texi (Lisp Eval): Document it.
* lisp/emacs-lisp/pp.el (pp-eval-last-sexp): Ditto.
* lisp/progmodes/elisp-mode.el (elisp--eval-last-sexp): Work more
like `eval-defun': Re-evaluate defvar/defcustom/defface forms.
* lisp/progmodes/grep.el (grep-expand-template): Add new arg 'more-opts'.
(grep-use-directories-skip): New variable.
(lgrep): Set 'grep-use-directories-skip' to the result of 'grep-probe'.
Use "--directories=skip" when 'grep-use-directories-skip' is t.
* lisp/progmodes/grep.el (lgrep): Do the directory ignores here
(bug#23590).
(grep-compute-defaults): ... instead of here, because this would
affect all grep commands, not just lgrep.
This should allow auto, const, static, ... to be in any order.
* lisp/progmodes/cc-engine.el (c-forward-type): New return value 'no-id for
when auto precludes the parsing of a type identifier. Adapt processing for
this.
(c-forward-decl-or-cast-1): Use the new facility from c-forward-type.
* lisp/progmodes/cc-langs.el (c-type-modifier-prefix-kwds): Insert the value
of c-no-type-kwds into the value.
(c-no-type-kwds, c-no-type-key): New lang consts/vars, basically "auto".
(c-typeless-decl-kwds, c-modifier-kwds): Remove "auto" from the C++ value.
* lisp/progmodes/cc-styles.el (c-set-style): Use kill-local-variable rather
than copying the hook's global value to the local binding.
(c-make-styles-buffer-local): Remove redundant make-variable-buffer-local.
* lisp/progmodes/python.el (python-shell-send-statement): Don't
send a cookie, because that leads to the naked expression not
being evaled (bug#43450).
(python-shell-send-region): Allow not sending a cookie.
(python-shell-buffer-substring): Ditto.
* lisp/progmodes/sql.el (sql-add-product): Re-correct argument
spec. Previous change was due to my mistake; I have
resolved back to the prior behavior (Bug#39960).
* test/lisp/progmodes/sql-tests.el (sql-test-add-product): Added
test to insure I don't make the same mistake again.
* lisp/progmodes/cperl-mode.el (cperl--time-convert): New
compatibility helper for time-convert (available in Emacs
27.1)
(cperl--format-prompt): New compatibility helper for
format-prompt (available in Emacs 28)
(cperl-info-on-command): use cperl--format-prompt
(cperl-perldoc): use cperl--format-prompt
(cperl-time-fontification): use cperl--time-convert (bug#43652)
* doc/emacs/building.texi (Grep Searching): Document it.
* lisp/progmodes/grep.el (grep-match-regexp): New variable (bug#41766).
(grep-filter): Use it.
* lisp/progmodes/cperl-mode.el (cperl-force-face): This
macro's single effect is now inlined, and the macro is gone.
(cperl-problems): The reference to choose-color.el, which
is no longer available for download, is deleted.
(no function): A list of unnecessary empty variable
definitions is gone. They were needed for Emacs v19 and
below.
(cperl-init-faces-weak): This function does no longer do
anything and is therefore deleted.
(cperl-init-faces): Some bodies of conditional code is deleted
because as of today the conditions evaluate to constants. The
face cperl-nonoverridable-face is no longer available as
variable and needs to be doubly-quoted in one place (bug#43622).
(ruby-mode-map, ruby-mode-menu): Don't use ruby-for/backward-sexp any more.
(ruby-mode-variables): Always setup SMIE navigation.
Still obey `ruby-use-smie` for indentation.
(ruby-forward-sexp, ruby-backward-sexp): Mark as obsolete.
Since "using" is now used in three distinct ways in C++, write a special
function to handle these rather than attempting to adapt the old regular
expressions.
* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): Amend to allow the
argument TYPES to be a face. This face is given to the declarator being
processed.
(c-font-lock-single-decl): Make an argument to c-font-lock-declarators nil or
t, not merely nil or non-nil.
(c-complex-decl-matchers): Include c-font-lock-c++-using in the C++ value of
this variable.
(c-font-lock-c++-using): New function.
* lisp/progmodes/cc-langs.el (c-using-kwds, c-using-key): New lang
consts/vars.
(c-modifier-kwds): Remove "using" from the C++ value.
* lisp/progmodes/cperl-mode.el (cperl-style-alist)
(cperl-set-style): Add indentation style recommended by Damian Conway's
book "Perl Best Practices".
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-mode-test-indent-styles): Add a test to verify indentation
and unraveling of conditionals (bug#43457).
