* lisp/simple.el (yank): Mention 'current-kill' in the doc string,
so that people could find all the gory details of what is "the most
recent kill" for this purpose. (Bug#40375)
* lisp/erc/erc-track.el (erc-track-switch-buffer): Factor out the
implementation from here ...
(erc-track--switch-buffer): ... to here.
(erc-track-switch-buffer-other-window): New function, like
`erc-track-switch-buffer', but uses `switch-to-buffer-other-window'
instead, to open the buffer in another window.
* lisp/erc/erc.el (erc-switch-to-buffer): Factor out the buffer choice
implementation from here ...
(erc--switch-to-buffer): ... to here.
(erc-switch-to-buffer-other-window): New function, like
`erc-switch-to-buffer', but uses `switch-to-buffer-other-window'
instead, to open the buffer in another window.
'gnus-shorten-url' (used by 'gnus-summary-browse-url') ignored
fragment identifiers and didn't check substring bounds, in some cases
leading to runtime errors, e.g.:
(gnus-shorten-url "https://some.url.with/path/and#also_a_long_target" 40)
;; => Lisp error: (args-out-of-range "/path/and" -18 nil)
This commit makes it account for #fragments and fixes faulty string
computation. (bug#39980)
Do not merge to master, where the helper is put to subr-x.el.
* lisp/gnus/gnus-sum.el (gnus--string-truncate-left): New helper
function (copied from 'ediff-truncate-string-left').
(gnus-shorten-url): Use it and don't drop #fragments.
* doc/lispintro/emacs-lisp-intro.texi (Prevent confusion): Mention
that dynamic scoping is only the default in Emacs Lisp, not the
only scoping rule. (Bug#40594)
* lisp/simple.el (compose-mail): Clarify the effect of the
CONTINUE argument.
* lisp/mail/sendmail.el (mail-from-style): Update the RFC value in
the obsolescence warning text.
* doc/emacs/sending.texi (Sending Mail): Fix the description of
the behavior of 'C-x m' wrt prefix argument.
(Mail Headers): Remove the description of 'mail-from-style'.
* etc/NEWS: Mention that 'mail-from-style' is obsolete.
(Bug#40561)
* src/xfns.c (Fx_gtk_debug, Sx_gtk_debug): Define only for GTK
versions >= 3.14.0 so gtk_window_set_interactive_debugging is
defined. Reported by Andreas Schwab <schwab@linux-m68k.org>.
* doc/emacs/display.texi (Scrolling): Add a paragraph on using jit-lock
deferred fontification as a way of obviating Emacs hanging after
auto-repeated scrolling.
Don't make it sound like `:key-sequence nil` is any different than the
absence of `:key-sequence`. And the performance advantage of
`:key-sequence` disappeared long ago.
* src/dispnew.c (update_window): Reset the window's
'must_be_updated_p' flag if the window's update was completed
without interruption. This fixes redisplay glitches when
'redisplay-dont-pause' is nil, at least on MS-Windows, because
'expose_window' doesn't redraw the exposed rectangle when the
window's 'must_be_updated_p' flag is set.
* lisp/cedet/pulse.el (pulse-reset-face): Propagate the :extend
attribute of FACE to the face used for displaying the pulse.
Reported by Adam Porter <adam@alphapapa.net>.
* lisp/jit-lock.el (jit-lock-contextually): Clarify the jit-lock
operation when 'jit-lock-contextually' is non-nil and non-t.
* doc/lispref/modes.texi (Syntactic Font Lock)
(Other Font Lock Variables): Document the relation between
'jit-lock-register', 'font-lock-keywords-only', and syntactic
refontification.
* src/gtkutil.c (xg_frame_set_char_size): Skip resizing if the
target dimensions are unchanged for child frames with
'resize-mode' resize policy as well.
(1) Provide new option 'x-gtk-resize-child-frames' which allows
to either hide a child frame during resizing or asks GTK to
resize it "immediately". This is needed because desktops like
GNOME shell otherwise won't allow resizing child frames at all.
(2) Do not try to synchronize the position of a child frame
after moving it. Needed because the present implementation
introduces a 0.5 secs delay which makes dragging child frames
virtually impossible with Lucid and Motif toolkits on desktops
like GNOME shell that use invisible outer frame borders.
For further information see the thread starting with
https://lists.gnu.org/archive/html/emacs-devel/2020-01/msg00343.html
* src/frame.c (syms_of_frame): New symbol Qxg_frame_set_char_size_4.
* src/gtkutil.c (xg_frame_set_char_size): Hide child frame
during resizing when 'x-gtk-resize-child-frames' equals 'hide'.
* src/xfns.c (x_set_parent_frame, Fx_create_frame): Set
gtk_container_resize_mode to GTK_RESIZE_IMMEDIATE for child
frames when'x-gtk-resize-child-frames' equals 'resize-mode'.
(Fx_gtk_debug): New function to toggle interactive GTK debugging
from within Emacs.
(syms_of_xfns): New symbols Qhide and Qresize_mode.
(x-gtk-resize-child-frames): New option that allows to resize
child frames on desktops like GNOME shell (with the mutter WM)
that otherwise refuse to resize them.
* src/xterm.c (x_set_offset): Don't x_sync_with_move for child
frames, it makes moving child frames virtually impossible with
the Lucid and Motif toolkits.
* doc/man/emacs.1.in: Fix syntax of --script argument. The Info
manual states that --script has to be followed by a space, and the
syntax with the equals sign doesn't actually work.
* lisp/vc/log-edit.el (log-edit-fill-entry): Relax regexp a bit to
recognize function entries with leading blanks.
* test/lisp/vc/log-edit-tests.el: New test.
* lisp/emacs-lisp/re-builder.el (reb-while): Take the current value of
the counter instead of its name.
(reb-mark-non-matching-parenthesis): Bind n-reb to 0 at the start and
don't wrongly treat it as dynamicly bound.
* src/emacs-module.c (module_copy_string_contents): Fix incorrect
variable use. In this branch 'lisp_str_utf8' is always nil, so it
makes little sense to add it as error data.
* lisp/epg-config.el (epg-config--make-gpg-configuration): Bind
coding-system-for-read/write to 'undecided', to countermand
possible values of 'no-conversion' or somesuch by the callers.
(Bug#40248)
* src/xterm.c (x_clear_under_internal_border): For GTK builds
have 'margin' count in the height of the tab bar to avoid that
tab bar and internal border are drawn on top of each other.
* lisp/htmlfontify.el (hfy-default-header): declare the character
encoding for the generated HTML file. This helps browsers display
UTF-8 characters like the copyright symbol correctly.
(hfy-sprintf-stylesheet): apply the default style to all of the text
consistently, so that unstyled bits (which are not wrapped in span
tags and are directly part of the surrounding pre tag's "innerHTML")
have a look consistent with the rest of the document.
* lisp/progmodes/project.el (project--find-regexp-in-files):
Signal user-error when passed an empty list of files.
* lisp/progmodes/xref.el (xref-matches-in-files):
Make sure FILES is not empty.
* lisp/imenu.el (imenu-update-menubar): No longer accept a list of length 1 as
being sufficient evidence for a nested list structure. Instead, additionally
check whether or not certain elements are atoms.
Make Math-num-integerp return false for nil, following Math-integerp
which was changed in the bignum reform. This fixes a crash in
calc-graph-fast.
Reported by Narendra Joshi.
* lisp/calc/calc-macs.el (Math-num-integerp): Not true for nil.
* test/lisp/calc/calc-tests.el (calc-Math-integerp): New tests.
* lisp/svg.el (svg-create): Fix previous unconditional addition of
the xmlns:xlink declaration -- callers may already add one, and
having it twice is something most svg libraries doesn't like.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_utimens): Omit the
'utimens' module in the MinGW build: 'utimens' is not used by
Emacs, and 'fdutimens' is implemented in w32.c.
