# Conflicts:
# etc/NEWS
* lisp/emacs-lisp/cl-extra.el (cl-random):
Perform the modulo 2**23 operation before updating the state instead
of after. The result is always the same, but it prevents the state
from growing into arbitrary large bignums.
Patch from Christopher Wellons.
* doc/lispref/functions.texi (Obsolete Functions): Make
documentation of functions that obsolete symbols match the
advertised calling conventions.
* lisp/emacs-lisp/byte-run.el (define-obsolete-function-alias)
(define-obsolete-variable-alias, define-obsolete-face-alias):
State in the doc strings that WHEN is a mandatory argument, to be
consistent with the advertised calling convention. (Bug#38675)
* lisp/emacs-lisp/bytecomp.el (byte-compile-get-constant):
Use eql for looking up constants instead of eq, allowing
for bignum and flonum deduplication (bug#38708).
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Treat all expressions in the body of 'while' as for-effect,
since their values are discarded. This also finds some errors.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt):
* doc/lispref/searching.texi (Regexp Functions):
Be more specific about how the KEEP-ORDER argument actually works.
If nil, the regexp guarantees a longest match; this is the behaviour
that many callers implicitly rely on.
The `not' and `intersection' forms, and `or' inside these forms,
now accept characters and single-character strings as arguments.
Previously, they had to be wrapped in `any' forms.
This does not add expressive power but is a convenience and is easily
understood.
* doc/lispref/searching.texi (Rx Constructs): Amend the documentation.
* etc/NEWS: Announce the change.
* lisp/emacs-lisp/rx.el (rx--charset-p, rx--translate-not)
(rx--charset-intervals, rx): Accept characters and 1-char strings in
more places.
* test/lisp/emacs-lisp/rx-tests.el (rx-not, rx-charset-or)
(rx-def-in-charset-or, rx-intersection): Test the change.
* lisp/help.el (help-uni-confusables, help-uni-confusables-regexp):
Rename from uni-confusable and uni-confusables-regexp, respectively.
(help-uni-confusable-suggestions): Use ngettext. Use new variable
name.
* lisp/emacs-lisp/lisp-mode.el (lisp--match-confusable-symbol-character):
Use new variable name.
Allow placing debug-on-entry on a function not-yet-defined, which
is convenient when the problem you're investigating happens while
the relevant files are loaded.
These character set operations, together with `not' for set
complement, improve the compositionality of rx, and reduce duplication
in complicated cases. Named character classes are not permitted in
set operations.
* lisp/emacs-lisp/rx.el (rx--translate-any): Split into multiple
functions.
(rx--foldl, rx--parse-any, rx--generate-alt, rx--intervals-to-alt)
(rx--complement-intervals, rx--intersect-intervals)
(rx--union-intervals, rx--charset-intervals, rx--charset-union)
(rx--charset-all, rx--charset-intersection, rx--translate-union)
(rx--translate-intersection): New.
(rx--translate-not, rx--translate-form, rx--builtin-forms, rx):
Add `union' and `intersection'.
* test/lisp/emacs-lisp/rx-tests.el (rx-union ,rx-def-in-union)
(rx-intersection, rx-def-in-intersection): New tests.
* doc/lispref/searching.texi (Rx Constructs):
* etc/NEWS:
Document `union' and `intersection'.
This reverts the last change that replaced [remap self-insert-command]
with [t]. The user should have freedom of using any command
in the minibuffer. (bug#32738)
Treat SHORT-ANSWER as a character is characterp returns non-nil.
Otherwise, use key-description to print it.
Use catch-all [t] in keymap instead of [remap self-insert-command].
(bug#32738)
Although 'push' returns the modified list, it isn't actually
documented to do so, so don't rely on it.
* lisp/emacs-lisp/rx.el (rx--translate-any): Add progn.
For example, (any digit digit) should produce "[[:digit:]]",
not "[[:digit:][:digit:]]".
* lisp/emacs-lisp/rx.el (rx--translate-any): Deduplicate character classes.
* test/lisp/emacs-lisp/rx-tests.el (rx-any): Add test case.
* lisp/window.el (window-state-buffers): New function.
* lisp/tab-bar.el (tab-bar-get-buffer-tab): New function.
* lisp/emacs-lisp/seq.el (seq-some): Add autoload cookie.
* lisp/desktop.el (desktop-buffers-not-to-save-function): New variable.
(desktop-save-buffer-p): Use it.
Add some hints to the message for byte compiler free & unused variable
warnings, and 'void-variable' errors where the variable has confusable
quote characters in it.
* lisp/help.el (uni-confusables), uni-confusables-regexp): New
constants.
(help-command-error-confusable-suggestions): New function, added to
`command-error-function'.
(help-uni-confusable-suggestions): New function.
* lisp/emacs-lisp/bytecomp.el (byte-compile-variable-ref):
* lisp/emacs-lisp/cconv.el (cconv--analyze-use): Use it.
* lisp/emacs-lisp/lisp-mode.el
(lisp--match-confusable-symbol-character): New function.
(lisp-fdefs): Use it to fontify confusable characters with
font-lock-warning-face when they occur in symbol names.
* doc/lispref/modes.texi (Faces for Font Lock):
* doc/lispref/objects.texi (Basic Char Syntax): Recommend backslash
escaping of confusable characters, and mention new fontification.
* etc/NEWS: Announce the new fontification behavior.
* test/lisp/emacs-lisp/lisp-mode-tests.el (lisp-fontify-confusables):
New test.
* lisp/emacs-lisp/timer.el (debounce, debounce-reduce): New macros.
* lisp/image.el (image-increase-size, image-decrease-size):
Use funcall to call image--change-size-function.
(image--change-size-function): Move code from defun of
image--change-size to defvar that has the value of lambda
returned from debounce-reduce. (Bug#38187)
* lisp/emacs-lisp/package.el (package-generate-autoloads)
(package--compile, package--save-selected-packages): Don't use
'inhibit-message' to bind 'noninteractive' and 'save-silently',
since 'inhibit-message' already disables all messages.
(Bug#38264)
Handle the case where the token is not in `smie-grammar`, either because
the caller is making an error, or because it's a paren-like token that's
not handled in the grammar but directly via the syntax tables.
* lisp/emacs-lisp/macroexp.el (macroexp-macroexpand): Pass the
macro/alias symbol on to byte-compile-warning-enabled-p so that
with-suppressed-warnings works for macros, too.
