In async mode, the workaround for the old Terminal.app collides
with the binding we install for the primary DA. Just drop it.
* lisp/term/xterm.el (xterm--init): Remove workaround for very old
macOS `Terminal.app`.
* lisp/term/xterm.el (xterm-update-cursor): Mention OSC 112 in
doc string.
(xterm--reset-cursor-color-escape-sequence): New constant.
(xterm--init-update-cursor, xterm--update-cursor-color): Use it
(bug#80091).
* lisp/term/xterm.el (xterm-update-cursor): New user option.
(xterm--init): Use it.
(xterm--post-command-hook): New function for all xterm
functionality installed in 'post-command-hook'.
(xterm--init-frame-title): Install it.
(xterm--init-update-cursor, xterm--set-cursor-type)
(xterm--update-cursor-type, xterm--update-cursor-color): New
functions.
(xterm--cursor-type-to-int): New constant.
* doc/emacs/display.texi (Cursor Display):
* etc/NEWS: Document the new feature.
Foot supports all features required for this (OSC-52, DECSET1000,
DECSET1003).
* lisp/term/xterm.el (xterm--auto-xt-mouse-allowed-names):
Add foot. (Bug#80083)

Up until recently, there were no reliable way to detect if a terminal
supported OSC-52 or not.
A number or terminal emulators decided to remedy this by including '52'
in their primary DA response. In short, the presence of 52 in the DA
response means the terminal supports *writing* to the clipboard.
Reading the clipboard is _usually_ supported, but not guaranteed.
It should be noted that Emacs uses both the 'c' and 'p' parameters in
OSC-52, to copy to either PRIMARY, or CLIPBOARD, while the specification
only requires the terminal to implement 'c'. If a terminal doesn't
support 'p', the OSC-52 request will be silently ignored.
* lisp/term/xterm.el (xterm--init, xterm--primary-da-handler):
Query primary device attributes for OSC-52 support. (Bug#80083)
Copyright-paperwork-exempt: yes
* lisp/term/xterm.el (xterm--report-background-handler)
(xterm--report-foreground-handler): Record tty background and
foreground color in terminal parameters.
(xterm--version-handler): Also query foreground color.
(xterm--init): Also query foreground color; move background and
foreground color handling here.
(xterm--set-background-mode): Rename from
xterm-maybe-set-dark-background-mode; now always set background
mode to dark or light.
(xterm-maybe-update-default-face): Update default face
background and foreground colors to terminal reported values if
they have not yet been customized.
Many terminals set the environment variable TERM to "xterm" even when they
don't support all functionality in xterm. This means that enabling
xterm-mouse-mode can break critical editing workflows like copy/paste. This
adds checks for the specific terminal Emacs is run in and only enables
xterm-mouse-mode on terminals knows to support all critical editing workflows.
* etc/NEWS: Update announcement
* lisp/term/xterm.el (xterm--auto-xt-mouse-allowed-names)
(xterm--auto-xt-mouse-allowed-types): New variables to control
what terminals automatically enable xterm-mouse-mode.
(xterm--report-background-handler, xterm--version-handler): Use
xterm--read-string.
(xterm--read-string, xterm--query-name-and-version): New
function.
(xterm--init): Check what terminal is running and if
xterm-mouse-mode was manually called.
* lisp/xt-mouse.el (xterm-mouse-mode-called): New variable.
(xterm-mouse-mode): Set xterm-mouse-mode-called. Mention
automatic call by xterm--init. Delete outdated comment text.
* lisp/xt-mouse.el (xterm-mouse-mode): Change default value of
xterm-mouse-mode to t.
* lisp/term/xterm.el (xterm--init): Enable xterm-mouse-mode if
the default value is still set.
* etc/NEWS: Document new behavior.
* lisp/frame.el (tty-select-active-regions): Rename from
xterm-select-active-regions and move here from xterm.c.
(display-selections-p): Adjust to the above. (Bug#55883)
This allows Emacs to save the active region to the user's
primary selection on supported terminals. The behavior follows
the existing `select-active-regions' variable and requires
`xterm-select-active-regions' to be non-nil.
* src/keyboard.c (command_loop_1):
* lisp/frame.el (display-selections-p): On text terminals, check
terminal parameter `xterm--set-selections' and variable
`xterm-select-active-regions' when deciding whether to update
primary selection. (bug#55883)
* lisp/term/xterm.el (xterm-select-active-regions): New
defcustom.
* lisp/international/quail.el (quail-add-unread-command-events):
New function.
(quail-start-translation, quail-start-conversion)
(quail-update-translation, quail-next-translation)
(quail-prev-translation, quail-next-translation-block)
(quail-prev-translation-block, quail-minibuffer-message): Use
'quail-add-unread-command-events' (and partly revert commit
03e3440dbb). (Bug#48042)
* lisp/subr.el (inhibit--record-char): Now obsolete.
* lisp/term/xterm.el (xterm--init): New function, with most of the
code of former 'terminal-init-xterm'.
(terminal-init-xterm): Clear the lossage after terminal
initialization (see Bug#44908).
(xterm--read-event-for-query): Do not use 'inhibit--record-char'
anymore (revert commit 3e6525d69f).
* src/keyboard.c (syms_of_keyboard): Remove 'inhibit--record-char'
(partly revert 03e3440dbb).
(record_char, syms_of_keyboard_for_pdumper): Do not use
'inhibit_record_char anymore'.
* lisp/term/xterm.el (xterm--read-event-for-query): Prevent
recording the characters read as the xterm response to a query,
so as not to show them in 'view-lossage'. (Bug#44908)
When asking XTerm for the selection via OSC 52, use ST as string
terminator in the request to get ST as terminator in the reply,
because BEL is messy to receive in many ways.
* lisp/term/xterm.el (gui-backend-get-selection):
Use ST as string terminator in request and reply.
Use a time-out when reading the reply.
I audited use of lsh in the Lisp source code, and fixed the
glitches that I found. While I was at it, I replaced uses of lsh
with ash when either will do. Replacement is OK when either
argument is known to be nonnegative, or when only the low-order
bits of the result matter, and is a (minor) win since ash is a bit
more solid than lsh nowadays, and is a bit faster.
* lisp/calc/calc-ext.el (math-check-fixnum):
Prefer most-positive-fixnum to (lsh -1 -1).
* lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width,
prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1
32)) (Bug#32485#11).
* lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode):
Tighten sanity-check for bytecode overflow, by checking that the
result of (ash pc -8) is nonnegative. Formerly this check was not
needed since lsh was used and the number overflowed differently.
* lisp/net/dns.el (dns-write): Fix some obvious sign typos in
shift counts. Evidently this part of the code has never been
exercised.
* lisp/progmodes/hideif.el (hif-shiftleft, hif-shiftright):
* lisp/term/common-win.el (x-setup-function-keys):

focus-in-hook and focus-out-hook don't accurately reflect actual
user-visible focus states. Add a new focus interface and mark the old
one obsolete.
* doc/lispref/frames.texi (Input Focus): Document new focus
functions. Remove references to the now-obsolete focus hooks.
* lisp/frame.el (frame-focus-state): New function.
(after-focus-change-function): New variable.
(focus-in-hook, focus-out-hook): Move to lisp from C;
mark obsolete.
* lisp/term/xterm.el (xterm-translate-focus-in)
(xterm-translate-focus-out): Track tty focus in `tty-focus-state'
terminal parameter; call `after-focus-change-function'.
(xterm--suspend-tty-function): New function.
* src/frame.c (Fhandle_switch_frame): Update docstring; don't call
focus hooks.
(focus-in-hook, focus-out-hook): Remove: moved to lisp.
(syms_of_frame): Remove unread_switch_frame; add
Vunread_switch_frame.
* src/keyboard.c:
(Finternal_handle_focus_in): New function.
(make_lispy_event): Always report focus events to lisp; don't
translate them to switch events sometimes. Lisp can take care of
creating synthetic switch-frame events via
`internal-handle-focus-in'.
* src/w32term.c (x_focus_changed): Remove switch-avoidance logic:
just directly report focus changes to lisp.
* src/xterm.c (x_focus_changed): Remove switch-avoidance logic:
just directly report focus changes to lisp.
We used to treat the start of a focus-in, focus-out, and the start of
a paste sequence as normal events bound in global-map, but this
approach produces problems when we recognize events in the middle of
actions that don't immediately dispatch to the command loop.
Now we handle these events internally inside read-key, translating the
focus events to nothing and paste-start into an xterm-paste event that
neatly encapsulates the entire paste sequence.
* lisp/term/xterm.el:
(xterm-paste): Accept an event argument; insert text from event.
(xterm-translate-focus-in,xterm-translate-focus-out)
(xterm-translate-bracketed-paste): New functions.
(xterm-handle-focus-in,xterm-handle-focus-out): Remove.
(xterm-rxvt-function-map): Bind new translation functions.
We query some properties of the terminal early in initialization, and
just before we do, we perform ordinary redisplay. This redisplay can
result in unsightly flickering if we change some aspects of the
display immediately afterward and redisplay again. By avoiding
redisplay in xquery--query as long as we get timely responses from the
terminal, we can avoid this early unwanted redisplay.
* lisp/term/xterm.el:
(xterm-query-redisplay-timeout): New variable.
(xterm--read-event-for-query): New function.
(xterm--report-background-handler,xterm--version-handler,xterm--query):
Call it.
* lisp/frame.el (handle-focus-in,handle-focus-out): Make event
argument optional.
(blink-cursor-check): Make sure that the current frame is a
window-system frame before restarting the blink timer. TTY frames
can get focus, but don't need a blink timer because the terminal
will do the blinking.
* lisp/term/xterm.el
(xterm-handle-focus-in,xterm-handle-focus-out): New functions.
(xterm-rxvt-function-map): Recognize focus notification sequences.
(xterm--init-focus-tracking): New function.
(terminal-init-xterm): Call it.
