Provide a new option 'arabic-shaper-ZWNJ-handling' that controls how
to display ZWNJ in Arabic text rendering (Bug#28339).
* lisp/language/misc-lang.el: Register arabic-shape-gstring in
composition-function-table.
(arabic-shaper-ZWNJ-handling): New variable.
(arabic-shape-log): New variable.
(arabic-shape-gstring): New function.
* lisp/composite.el (lgstring-remove-glyph): New function.
Although the Lisp manual said that ‘format’ returns a
newly-allocated string, this was not true for a few cases like
(format "%s" ""), and fixing the documentation to allow reuse of
arguments lets us improve performance in common cases like
(format "foo") and (format "%s" "foo") (Bug#28625).
* doc/lispref/strings.texi (Formatting Strings):
* etc/NEWS:
Say that the result of ‘format’ might not be newly allocated.
* src/callint.c (Fcall_interactively):
* src/dbusbind.c (XD_OBJECT_TO_STRING):
* src/editfns.c (Fmessage, Fmessage_box):
* src/xdisp.c (vadd_to_log, Ftrace_to_stderr):
Just use Fformat or Fformat_message, as that’s simpler and no
longer makes unnecessary copies.
* src/editfns.c (styled_format): Remove last argument, as it
is no longer needed: all callers now want it to behave as if it
were true. All remaining callers changed. Make this function
static again. Simplify the function now that we no longer
need to worry about whether the optimization is allowed.
Problem reported by N. Jackson (Bug#28597).
This improves an earlier suggestion by Robert Pluim (Bug#28597#47).
* INSTALL, configure.ac, etc/NEWS:
Make --with-pop the default only on native MS-Windows.
This fixes some URLs I omitted from my previous pass,
notably those in lists.gnu.org. Although lists.gnu.org
does not yet support TLS 1.1, TLS 1.0 is better than nothing.
* lisp/erc/erc.el (erc-official-location):
* lisp/mail/emacsbug.el (report-emacs-bug):
Use https:, not http:.
* etc/NEWS (Changes in Emacs 26.1): Remove an entry about
'find-library' taking a prefix argument to pop to a different
window. This behavior was added in "Allow a prefix argument to
find-library to pop to a different window" (commit e1f2d14a), and
then removed in "New commands: find-library-other-window,
find-library-other-frame" (commit 021430f4).
* doc/lispref/control.texi (Signaling Errors):
* doc/lispref/display.texi (Displaying Messages):
* doc/lispref/strings.texi (Formatting Strings):
Edit for brevity, farming out the details to the new
Text Quoting Style node.
* doc/lispref/help.texi (Text Quoting Style): New section.
Move detailed discussion of text-quoting-style here.
Add discussion about how to output grave accent and apostrophe in
documentation and messages. Adjust xrefs to point to this section
when appropriate.
* etc/NEWS: text-quoting-style semantics have not changed.
This is a partial reversion of yesterday's commit by the same author, which
changed the meaning of nil and introduced the new value t.
* src/doc.c (text_quoting_style, text-quoting-style)
(internal--text-quoting-flag): Revert yesterday's changes.
* lisp/cus-start.el: (top level): Amend the entry for text-quoting-style.
* etc/NEWS: Amend the entry for text-quoting-style.
* doc/lispref/control.texi (Signalling Errors)
* doc/lispref/display.texi (Displaying Messages)
* doc/lispref/strings.texi (Formatting Strings): Bind text-quoting-style to
grave rather than nil to inhibit translation of quotes.
* doc/lispref/help.texi (Keys in Documentation): Revert the description of the
proposed new default, t.
A value of nil for text-quoting-style now means "no translation". t means
"Use curved quotes if displayable".
* src/doc.c (text-quoting-style (function)): modify for new semantics.
(text-quoting-style (variable)): Amend the doc string, set the default value
to t.
* lisp/cus-start.el: (top level): Create a customize entry for
text-quoting-style in group display.
* etc/NEWS: Amend the entry for text-quoting-style.
* doc/emacs/display.texi (Text Display): Describe the translation of ASCII
quotes to curved quotes, and how to influence or inhibit it.
* doc/lispref/control.texi (Signalling Errors)
* doc/lispref/display.texi (Displaying Messages)
* doc/lispref/strings.texi (Formatting Strings): Describe binding
text-quoting-style to nil to inhibit unwanted quote translation.
* doc/lispref/help.texi (Keys in Documentation): Change text-quoting-style
from a variable to a user option. Describe its changed set of values. State
that it can be customized freely.
* lisp/vc/vc-hooks.el (vc-prefix-map):
Bind `vc-region-history' to 'C-x v h', which was earlier bound to
`vc-insert-headers' (Bug#27644).
* doc/emacs/maintaining.texi (VC Change Log): Mention the new binding.
* doc/emacs/vc1-xtra.texi (Version Headers): Remove the association of
'C-x v h' with `vc-insert-headers'.
(http://lists.gnu.org/archive/html/emacs-devel/2017-09/msg00957.html)
But wait specfically for a MapNotify event, and only for a
configurable amount of time.
* src/xterm.c (syms_of_xterm) [x-wait-for-event-timeout]: New
variable.
(x_wait_for_event): Use it instead of hardcoding the wait to 0.1s.
(x_make_frame_visible): Call x_wait_for_event at the end.
* etc/NEWS: Announce x_wait_for_event.
Also revert ee512e9a82
* lisp/files.el (buffer-offer-save): In addition to nil and t, now
allows a third symbol value, `always'. A buffer where this option is
set to `always' will always be offered for save by
`save-some-buffers'.
(save-some-buffers): Check the exact value of this buffer-local
variable. No longer check the buffer name, or the value of
`write-contents-functions'.
* doc/lispref/buffers.texi (Killing Buffers): Note change in manual.
* doc/lispref/files.texi (Saving Buffers): Remove note about buffer
names.
* etc/NEWS: Mention in NEWS.
* lisp/mouse.el (secondary-selection-exist-p): New function to
allow callers to tell existence of the secondary selection
in current buffer.
(secondary-selection-to-region): New function to set
beginning and end of the region from those of the secondary
selection.
(secondary-selection-from-region): New function to set
beginning and end of the secondary selection from those of
the region. (Bug#27530)
* etc/NEWS: Mention the new functions.
* etc/NEWS: Describe changes.
* lisp/term/ns-win.el (mouse-wheel-scroll-amount,
mouse-wheel-progressive-speed): Set to smarter values for macOS
touchpads.
* src/nsterm.m (emacsView::mouseDown): Use precise scrolling deltas to
calculate scrolling for touchpads and mouse wheels.
(syms_of_nsterm): Add variables 'ns-use-system-mwheel-acceleration',
'ns-touchpad-scroll-line-height' and 'ns-touchpad-use-momentum'.
* src/keyboard.c (make_lispy_event): Pass on .arg when relevant.
* src/termhooks.h (event_kind): Update comments re. WHEEL_EVENT.
* lisp/mwheel.el (mwheel-scroll): Use line count.
* lisp/subr.el (event-line-count): New function.
* src/buffer.c (Foverlays_at): If SORTED is non-nil, reverse the
list of results, to have their order as per the documentation.
(Bug#28390)
* etc/NEWS: Mention the change in the behavior of overlays-at.
* src/xdisp.c (handle_display_spec): If the display property is
wrapped in 'disable-eval' form, disable Lisp evaluation while
processing this property.
(handle_single_display_spec): Accept new argument ENABLE_EVAL_P.
If that argument is false, don't evaluate Lisp while processing
display properties.
* lisp/textmodes/enriched.el
(enriched-allow-eval-in-display-props): New defcustom.
(enriched-decode-display-prop): If
enriched-allow-eval-in-display-props is nil, wrap the display
property with 'disable-eval' to disable Lisp evaluation when the
display property is processed for display. (Bug#28350)
* lisp/gnus/mm-view.el (mm-inline-text): Re-enable processing of
enriched text.
* doc/lispref/display.texi (Display Property): Document the
'disable-eval' wrapping of 'display' properties.
* doc/emacs/text.texi (Enriched Properties): Document
'enriched-allow-eval-in-display-props'.
* etc/NEWS: Describe the security issues with Enriched Text mode
and their solution.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
configure.ac: Add boilerplate for configuring and detecting liblcms2.
etc/NEWS: Mention new configure option and color-distance change.
src/Makefile.in: Add references to lcms.c and liblcms.
src/emacs.c: Define lcms2 symbols.
src/lcms.c: New file.
src/lisp.h: Add declaration for lcms2.
src/xfaces.c: Add optional METRIC argument.
Bug#28412
* lisp/files.el (basic-save-buffer): Re-arrange function so that
write-contents-functions are run earlier. If they return non-nil,
consider the buffer saved without requiring the buffer to be
visiting a file.
(save-some-buffers): This function should consider any buffer with a
buffer-local value for write-contents-functions eligible for
saving.
* test/lisp/files-tests.el (files-test-no-file-write-contents): New
test.
* doc/lispref/files.texi (Saving Buffers): Mention in docs.
* etc/NEWS: And in NEWS.
This also includes changes to if-let and when-let. The single tuple
special case is ambiguous, and binding a symbol to nil is not as
useful as binding it to its value outside the lexical scope of the
binding. (Bug#28254)
* etc/NEWS: Mention.
* lisp/emacs-lisp/subr-x.el (internal--listify):
(internal--build-binding-value-form): Extend to account for
solitary symbols and (EXPR) items in binding varlist.
(if-let*, when-let*): Nix single tuple case and incumbent
bind-symbol-to-nil behavior.
(and-let*): New macro.
(if-let, when-let): Mark obsolete. Redefine in terms of if-let*, so
they implicitly gain the new features without breaking existing code.
* test/lisp/emacs-lisp/subr-x-tests.el: Adjust tests for: lack of
single-tuple special case, lack of binding solitary symbols to nil,
and the introduction of uninterned symbols for (EXPR) bindings. Add
SRFI-2 test suite adapted to Elisp.
The security patches released for Emacs 25.3 were less drastic
than what we had immediately put into master. Adjust master to
match 25.3 (Bug#28350).
* lisp/textmodes/enriched.el (enriched-translations):
Re-enable FUNCTION and display translations that are safe.
(enriched-handle-display-prop): Bring back.
(enriched-decode-display-prop): Bring back, but disable
the unsafe part.
* etc/NEWS: Mention this.
* lisp/thumbs.el (thumbs-rename-images): Treat the destination
as special only if it is a directory name. When there is
a marked list, turn the destination into a directory name
if it is not already.
Change write-file to be consistent with the new behavior
of copy-file, etc.
* etc/NEWS: Mention this.
* lisp/files.el (write-file): Treat the destination as special
only if it is a directory name.
