* lisp/cus-edit.el (custom-reset-extended-menu): Keymap menu for the
Revert... menu button.
(custom-reset-menu): Keep for backward compatibility, but default to
nil, so we prefer the keymap menu instead.
(custom-reset): Pass the new keymap menu to widget-choose.
(custom-commands): Add an element to each list item, to manage its
enable/disable state. Add docstring.
(custom-command-buttons): New variable, to hold the buttons that act
on all options in a Custom buffer.
(custom-buffer-create-internal): When creating the command buttons,
add the optional :notify function to enable/disable them. Add the
buttons to the new variable custom-command-buttons.
(customize-menu-create): Notify the command buttons after creating the
Custom buffer, so they are correctly enabled/disabled.
(custom-redraw-magic, custom-notify): Notify the command buttons and
update the tool bar when changing a widget to the modified state.
* lisp/net/eww.el (eww-display-pdf): Make *eww pdf* buffer unibyte
before populating it to avoid conversions. The binding for
coding-system-for-write is then no longer necessary, and can be
delegated to the viewer invoked by mailcap-view-mime. Suggested by
Stefan Monnier <monnier@iro.umontreal.ca>. (Bug#44338)
* doc/emacs/mini.texi (Basic Minibuffer): Add an entry for
minibuffer-follows-selected-frame.
* doc/lispref/minibuf.texi (Minibuffer Misc): Describe the new parameter to
minibufferp, LIVE.
* etc/NEWS: Add an entry describing the new minibuffer strategy.
* lisp/cus-start.el (minibuffer-prompt-properties--setter): Add an entry for
minibuffer-follows-selected-frame.
* lisp/minibuffer.el (minibuffer-message): Check for the current buffer being
an _active_ minibuffer rather than merely a minibuffer.
* src/frame.c (do_switch_frame): Call move_minibuffer_onto_frame.
* src/lisp.h (Top level): Add prototypes for move_minibuffer_onto_frame and
is_minibuffer.
* src/minibuf.c (minibuf_follows_frame): New function which ignores local and
let-bound values of minibuffer-follows-selected-frame.
(choose_minibuf_frame): Reformulate this function to reuse a minibuffer window
where possible, and to ensure no other frame has its minibuffer current, but
only when `minibuffer-follows-selected-frame'.
(move_minibuffer_onto_frame): New function.
(live_minibuffer_p): New function.
(Fminibufferp): Add a new &optional parameter LIVE. Reformulate, possibly
calling live_minibuffer_p.
(read_minibuf): move the incrementation of minibuf_level to before the call of
choose_minibuf_frame. Empty the miniwindows of frames without an active
minibuffer, rather than of all but the current frame.
(is_minibuffer): New function.
(read_minibuf_unwind): Note the miniwindow being restored and resize all other
miniwindows to zero size.
(minibuffer-follows-selected-frame): New configuration variable.
* src/window.c (candidate_window_p): In some scenarios, check the miniwindow
holds an active minibuffer.
* src/xdisp.c (get_window_cursor_type): Suppress the cursor for non-active
miniwindows, regardless of minibuf_level.
The *eww pdf* buffer is only needed when viewing PDFs within Emacs,
e.g., with doc-view-mode. External PDF viewers are called with a
temporary file, so the buffer is not needed in that case. What's
more, mailcap-view-mime erased the buffer and left it in
fundamental-mode until now, so the user was left staring at a
useless, empty buffer. To make things even worse, external viewers
were invoked synchronously until now, so the user could not browse
the PDF file and use Emacs simultaneously.
* lisp/net/mailcap.el (mailcap--async-shell): New function.
(mailcap-view-mime): Use it to invoke external viewers
asynchronously. Mention erasure of current buffer in that case in
docstring. Add a period between the temporary file name and its
extension.
* lisp/net/eww.el (eww-display-pdf): Simplify using
insert-buffer-substring. Fix coding-system-for-write for a stream
of raw bytes. Pop to *eww pdf* buffer only if it is used for
displaying a document; otherwise kill it. (bug#44338)
* lisp/textmodes/bibtex.el (bibtex-BibTeX-entry-alist): Fix
abbreviation of PhD.
(bibtex-biblatex-entry-alist, bibtex-biblatex-field-alist): Sync
standard entry and field types with those described in the biblatex
v3.15 manual of 2020-08-19 (bug#44322).
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-init-header):
Ensure sort indicator appears after the label of any selected
sortable column that is wide enough and enable label truncation
when narrowing a column.
* lisp/emacs-lisp/timer-list.el (timer-list-mode): Improve column
alignment.
(timer-list--function-predicate): Correct typo in doc string.
* src/bidi.c (bidi_at_paragraph_end, bidi_find_paragraph_start):
Bind inhibit-quit to a non-nil value around calls to
fast_looking_at, to prevent breaking out of redisplay_window,
which temporarily moves point in buffers shown in non-selected
windows. (Bug#44448)
Remove the `hold_quit` argument which was never used.
Streamline the control flow.
Thanks to Jared Finder <jared@finder.org> for pointing it out.
* src/keyboard.c (tty_read_avail_input): Simplify accordingly.
* lisp/gnus/gnus-search.el: Replace with an :initform tag on the slot
definition. `symbol-value' is necessary, otherwise the defclass macro
will treat the option as a quoted symbol.
* lisp/emacs-lisp/lisp-mode.el (lisp-el-font-lock-keywords-2)
(lisp-cl-font-lock-keywords-2): Highlight "hidden arg" even if it
already has another face.
Remove the gnus-search-gmane class and all associated methods. If
search functionality is ever resurrected, then revert this commit.
* lisp/gnus/gnus-search.el: Delete code, and remove from default value
of `gnus-search-default-engines'.
This library provides a fundamental reworking of the search
functionality previously found in nnir.el. It uses class-based search
engines to interface with external searching facilities, and a parsed
search query syntax that can search multiple engines.
* lisp/gnus/gnus-search.el: New library containing search
functionality for Gnus.
* doc/misc/gnus.texi: Document.
* lisp/gnus/gnus-group.el (gnus-group-make-search-group,
gnus-group-read-ephemeral-search-group): Remove references to nnir,
change meaning of prefix argument, change values of nnselect-function
and nnselect-args.
* lisp/gnus/nnselect.el: Replace references to nnir
(nnselect-request-article): Use gnus-search functions, and search
criteria.
(nnselect-request-thread, nnselect-search-thread): Use gnus-search
thread search.
(gnus-summary-make-search-group): Switch to use gnus-search function
and arguments.
* test/lisp/gnus/search-tests.el: Tests for new functionality.
* lisp/mwheel.el (mouse-wheel-scroll-amount-horizontal): New defcustom.
(mwheel-scroll): Use it.
* doc/emacs/frames.texi (Mouse Commands): Update doc about horizontal
scrolling step.
* lisp/progmodes/cperl-mode.el (cperl-mode): Add a fix
which is only required for Emacs versions older than 27.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug30393):
Add a test to verify correct indentation (bug#30393).
* lisp/cus-edit.el (face): Move the %f escape after the tag, because
otherwise customizing a face user option doesn't work:
custom-variable-value-create thinks that everything up until the first
":" is part of the tag, and the item widget doesn't know how to handle
the %f escape.
* lisp/pcmpl-cvs.el: Use lexical-binding.
(executable): Remove unnecessary require.
(pcmpl-cvs-binary): Remove redundant :group arg.
(pcmpl-cvs-tags): Quote function symbol as such.
* lisp/finder.el (finder-exit): Fix exiting the finder-commentary
buffer. (Bug#44384)
(finder-buffer): New defconst.
(finder-list-keywords): Use above new defconst.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug37127):
Skip this test for older Emacsen. The bug has been fixed
in Emacs, but outside of CPerl mode, and therefore will not
be available for older versions via ELPA.
* lisp/textmodes/ispell.el (ispell--call-enchant-lsmod): Restore the
use of with-current-buffer, to avoid enchant-lsmod’s output being
dumped into the current buffer.
