* mouse.el (context-menu-online-search): Add new function
(eww-search-prefix): Declare variable from eww.el
(mouse-online-search-at-point): Add new command
* lisp/battery.el (battery-status-function): In Termux, neither
/sys/ or /proc/ are readable on phones that are not rooted. This
patch makes Emacs verify if they are readable before it attemps
reading them (bug#53026).
Copyright-paperwork-exempt: yes
* lisp/progmodes/python.el (python-shell-send-string-no-output): Don't
let-bind comint-preoutput-filter-functions globally for all comint
processes. Modify the behaviour of only the current python
process (bug#53219).
* lisp/isearch.el (isearch-menu-bar-map, isearch-emoji-by-name):
Fix wording of documentation.
* etc/NEWS: Fix wording of the 'isearch-emoji-by-name' entry.
* doc/emacs/search.texi (Special Isearch): Fix wording of the
documentation of 'isearch-emoji-by-name'; move it out of the
enumeration that deals with non-ASCII characters in general.
* lisp/menu-bar.el (menu-bar-file-menu): Fix wording of the new
menu items and their help-echo. Don't show "Undelete Frame"
in the menu unless there is a frame to undelete.
* lisp/frame.el (undelete-frame): New command.
(undelete-frame--handle-delete-frame): New auxiliary function.
(undelete-frame--deleted-frames): New auxiliary variables.
(undelete-frame-mode): New minor mode.
(ctl-x-5-map): Bind the new command.
* etc/NEWS: Document the new command and minor mode.
* src/frame.c (Fdelete_frame): Update docstring, and mention the
minor mode.
* lisp/menu-bar.el (menu-bar-file-menu): Add an entry for the
new command.
* doc/emacs/frames.tex (Frame Commands): Document the new command
and minor mode.
See bug#51883.
The basic idea is, we're moving the setting/unsetting of
`gnus-registry-enabled' so that it is a more reliable indicator of
whether the registry is actually available or not.
* lisp/gnus/gnus-registry.el (gnus-registry-load): Move the setting of
`gnus-registry-enabled' here, after we're sure the registry actually
has been loaded.
(gnus-registry-initialize): Move it out of here. All this function
does is conditionally call `gnus-registry-load'.
(gnus-registry-register-message-ids): Only check
`gnus-registry-enabled', since we'd more confident about this
now. Sort checks in order of increasing complexity.
(gnus-registry-clear): Unset `gnus-registry-enabled'.
(gnus-registry-install-hooks): This function should only install
hooks, not set variables.
(gnus-registry-unload-hook): Change the unload hook to call
`gnus-registry-clear', as that will do all the necessary
work (including calling `gnus-registry-unload-hook')
* lisp/isearch.el (isearch-emoji-by-name): Add a new command to insert
Emoji characters into incremental search strings. (Bug#52605)
(isearch-mode-map): Bind it to 'C-x 8 e RET'.
(isearch-menu-bar-map): Add it to the menu bar.
* doc/emacs/search.texi (Special Isearch): Update the documentation to
mention the new command.
* etc/NEWS: And advertise it.
Lambda-lifted variables (ones passed explicitly to lambda-lifted
functions) that are also captured in an outer closure and shadowed
were renamed incorrectly (bug#51982).
Reported by Paul Pogonyshev.
* lisp/emacs-lisp/cconv.el (cconv--lifted-arg): New.
(cconv-convert): Provide correct definiens for the closed-over
variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
* test/lisp/emacs-lisp/cconv-tests.el (cconv-tests--intern-all)
(cconv-closure-convert-remap-var): Add tests.
(cherry picked from commit 45252ad8f9)
* lisp/eshell/esh-opt.el (eshell--split-switch): New function.
(eshell-set-option): Allow setting a supplied value instead of always
consuming from 'eshell--args'.
(eshell--process-option): Support consuming option values specified as
a single token.
(eshell--process-args): For short options, pass full switch token to
'eshell--process-option'.
* test/lisp/eshell/esh-opt-tests.el (esh-opt-process-args-test): Fix
test.
(test-eshell-eval-using-options): Add tests for various types of
options.
* doc/misc/eshell.texi (Defining new built-in commands): New
subsection, describe how to use 'eshell-eval-using-options'.
* etc/NEWS: Announce the change.
* lisp/gnus/gnus-art.el (gnus-treat-emphasize): Don't do emphasis
in text/html parts, because this leads to mis-filled text
(especially with *...* that's boldified, which typically becomes
much wider).
* lisp/window.el (display-comint-buffer-action):
Use display-buffer--same-window-action as the default value.
* lisp/progmodes/sh-script.el (sh-show-shell):
* lisp/shell.el (shell): Add display-comint-buffer-action to pop-to-buffer.
* lisp/progmodes/project.el (project-shell, project-eshell): Use
`bound-and-true-p display-comint-buffer-action' for backward-compatibility.
