Nowadays .elc files routinely contain tokens like 1.0e+INF and
0.0e+NaN that do not work on antiques like the VAX that lack IEEE fp.
Port Emacs to these platforms, by treating infinities as extreme
values and NaNs as strings that trap if used numerically.
* src/lread.c (INFINITY): Default to HUGE_VAL if non-IEEE.
(not_a_number) [!IEEE_FLOATING_POINT]: New static array.
(syms_of_lread) [!IEEE_FLOATING_POINT]: Initialize it.
(read0): Report invalid syntax for +0.0e+NaN on platforms
that lack NaNs.
(string_to_number): On non-IEEE platforms, return HUGE_VAL
for infinity and a string for NaN. All callers changed.
When pixel-scroll-precision-mode is enabled, scrolling the mouse
wheel will yield wheel-{up,down} events. Flymake now binds the
new events in addition to the old mouse-wheel-{up,down}-event.
* lisp/progmodes/flymake.el:(flymake--mode-line-counter-scroll-prev)
(flymake--mode-line-counter-scroll-next)
flymake--mode-line-counter-map): New.
(flymake--mode-line-counter): Use new keymap and include
'flymake--diagnostic-type' as a property in the mode-line.
(Bug#64428)
Some browers send eg 'text/html' selections formatted as UTF-8, but
with a type of STRING, which actually means iso-latin-1. Autodetect
the correct coding system to use by calling 'gui-get-selection'.
* lisp/yank-media.el (yank-media--get-selection): Call
'gui-get-selection' instead of 'gui-backend-get-selection'.
Avoid saying that 'project-current' asks specifically for a
directory, as it can also ask for a project's directory by other
identifiers, such as the project's name, when 'project-prompter'
is set to a different value than the default
'project-prompt-project-dir'. (Bug#64266)
* src/xterm.c (x_error_handler): Clear fail->selection_serial
after reporting an error during selection transfer, in case any
other outstanding requests within the protected section also
report errors.
* lisp/files.el (file-remote-p):
* doc/lispref/files.texi (Magic File Names): Document 'never' for
CONNECTED argument.
* lisp/net/tramp.el (tramp-handle-file-remote-p): Handle CONNECTED
value of 'never'.
* lisp/eshell/esh-ext.el (eshell-explicit-remote-commands): New
option.
(eshell-ext-initialize): Apply 'eshell-handle-remote-command' when
requested.
(eshell-handle-remote-command): New function.
(eshell-remote-command): Reimplement this function and dispatch to
'eshell-external-command', which can handle remote processes on its
own.
* test/lisp/eshell/esh-ext-tests.el
(esh-ext-test/explicitly-remote-command)
(esh-ext-test/explicitly-local-command): New tests.
* doc/misc/eshell.texi (Remote Access): Document explicitly-remote
commands.
* etc/NEWS: Announce this change.
* configure.ac (gl_STDLIB_H): Replace this, not gt_LOCALE_FR_UTF8,
as this lets us also omit MB_CUR_MAX checking that will never be
executed, and also lets us remove testing for ecvt, fcvt, gcvt
that Emacs doesn’t need.
(AC_C_RESTRICT): Invoke explicitly, as Emacs uses ‘restrict’
directly. Also, simplifies the replacement for gl_STDLIB_H, which
would otherwise need to AC_REQUIRE AC_C_RESTRICT.
* lib/gnulib.mk.in: Regenerate via admin/merge-gnulib.
* admin/merge-gnulib: Remove m4/locale-fr.m4.
* configure.ac (gt_LOCALE_FR_UTF8): Replace Gnulib’s
definition with a near no-op, as Emacs doesn’t care
about the Solaris 10 MB_CUR_MAX bug.
* lib/gnulib.mk.in: Regenerate.
* m4/locale-fr.m4: Remove; no longer needed due
to above changes.
While at it, fix a bug in `cl-print-object-contents` for strings,
where we forgot to pass `stream` to `princ` at one place and simplify
a `substring` call using a negative offset.
* lisp/emacs-lisp/cl-print.el (cl-print--cons-tail)
(cl-print--vector-contents, cl-print--struct-contents)
(cl-print--string-props): New functions, extracted from
`cl-print-object-contents`.
(cl-print-object, cl-print-object-contents): Use them.
* lisp/treesit.el (treesit-fontify-with-override): Fix docstring
grammar. Remove redundant precondition (bug#64052).
* src/treesit.c (Ftreesit_parser_set_included_ranges): Fix typo in
commentary.
(treesit_predicate_equal, treesit_predicate_match)
(treesit_predicate_pred): Avoid fixnum roundtrip by using
list_length in place of Flength. Make error messages more accurate.
(treesit_eval_predicates): Quote predicate names in error message.
* src/search.c: Move commentary that used to precede search_buffer
to that location once more. Update it for the current arglist.
(search_command, search_buffer_non_re, search_buffer):
* src/lisp.h (search_buffer): Turn RE flag/argument from an int into
a bool. All callers changed (bug#64049).
* lisp/net/tramp-sh.el (tramp-do-copy-or-rename-file): Set date
and modes if appropriate.
(tramp-do-copy-or-rename-file-via-buffer)
(tramp-do-copy-or-rename-file-directly)
(tramp-do-copy-or-rename-file-out-of-band): Do not set date and modes.
Now that it's not necessary to switch to the *Completions* buffer to
switch between and choose completions, we should make that clear in
the help text. Let's also make the bindings uniform both in and
outside the *Completions* buffer so users don't have to think about
the difference.
In working with new users, they've assumed that since the help text in
*Completions* says "Click on a completion to select it", that that's
the only way to select a completion. This text should help clarify
that.
* doc/emacs/mini.texi (Completion Commands): Document new bindings.
* lisp/simple.el (completion-list-mode-map): Bind
minibuffer-{next,previous,choose}-completion.
(completion-setup-function): Mention bindings for
minibuffer-{next,previous,choose}-completion. (Bug#64425)
* lisp/international/mule-conf.el (utf-7):
* lisp/language/cyrillic.el (koi8-u): Change mnemonic letters to
?u and ?\N{cyrillic capital letter u}, respectively.
* lisp/shell.el (shell-dirtrack-mode): Reverse the alias.
(shell-dirtrack-mode): Move before first use of the variable. Add
:interactive keyword.
(shell-directory-tracker, shell-cd): Use 'shell-dirtrack-mode'
instead of 'shell-dirtrackp'. (Bug#64311)
* test/lisp/calendar/icalendar-tests.el
(icalendar-export-bug-56241-dotted-pair):
This test started failing early July 2023 in multiple branches at
once without any change to the code and is likely sensitive to the
current date. Tag it to keep it quiet for now.
