In C, C++, Objective C, and Pike modes, regard \\ in a string
at EOL as a backslash followed by an escaped newline. In the
other languages, this remains regarded as an escaped backslash
followed by an invalid string terminator.
* lisp/progmodes/cc-defs.el (c-is-escaped, c-will-be-escaped):
Amend to observe the changed notion of escaped newlines.
* lisp/progmodes/cc-langs.el (c-string-escaped-newlines):
Unused, removed.
(c-escaped-newline-takes-precedence): New lang const and var.
(c-string-innards-re-alist): Amend, using the above new lang
var.
* lisp/progmodes/python.el (python-interpreter): Mention
new variable in documentation.
(python-interpreter-args): New custom variable.
(python-shell-interpreter, python-shell-interpreter-args)
(python-shell-interpreter-interactive-arg): Improve
documentation.
(python--list-imports, python--do-isort)
(python-fix-imports): Make process use customisable
arguments.
In the newline command, last-input-event is 13 (carriage return), but
most, if not all, language servers that support
documentOnTypeFormattingProvider expect 10 (linefeed) to be the
trigger, so convert 13 to 10 for the purposes of the
textDocument/onTypeFormatting request.
Also make this common edit silent in the mode-line/messages.
* lisp/progmodes/eglot.el (eglot--post-self-insert-hook): Convert
linefeed to carriage return.
(eglot-format): Pass SILENT to eglot--apply-text-edits.
(eglot--apply-text-edits): Take new optional SILENT arg.
* etc/EGLOT-NEWS: Mention change
* lisp/progmodes/eglot.el (eglot-imenu): Declare the correct name of
the server capability providing textDocument/documentSymbol.
Without this change, eglot-imenu always aborts even when used with
servers supporting textDocument/documentSymbol.
* lisp/progmodes/python.el (python--list-imports): Prefer to
use an exit status >1.
(python--list-imports-check-status): New function to check
status of Python script.
(python--do-isort): Fix wrong status check introduced with
6295d7abdd. (Bug#64406)
In some languages, the function name as displayed in the mode-line by
which-func-mode can be quite long. It's useful to be able to display
it in the header-line instead. Let's support that.
* lisp/progmodes/which-func.el (which-func-display)
(which-func--use-header-line, which-func--use-mode-line):
Add. (Bug#64533)
(which-func-try-to-enable): Support 'which-func--use-header-line'.
(which-func--disable): Add, to support 'which-func--use-header-line'.
(which-func-ff-hook, which-func-update-1): Use 'which-func--disable'.
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)
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)
Attributes may start with underscore, and must be separated.
Thanks to Mattias Engdegård for pointing out a regex mistake.
* lisp/progmodes/cperl-mode.el (defconst): Fix bad grouping and
allow attributes to start with an underscore in
cperl--single-attribute-rx. Adjust cperl--attribute-list-rx
accordingly.
(cperl-find-sub-attrs): Allow attributes to start with an underscore.
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-attribute-list-rx): Add new test cases for valid and
invalid attribute lists.
* lisp/progmodes/gdb-mi.el (gdb-target-async-checked): New
variable.
(gdb-non-stop-setting): Change the value back to default to
non-nil on systems other than MS-Windows.
(gdb-non-stop-handler): Try to set mi-async first, falling back to
target-async by calling 'gdb-set-mi-async-handler'.
(gdb-set-mi-async-handler, gdb-try-check-target-async-support):
New functions.
(gdb-check-target-async): Set 'gdb-non-stop' here...
(gdb-starting): ...and here.
(gdb-stopped): Call 'gdb-try-check-target-async-support' when the
program stops for the first time. (Bug#64186) (Bug#63084)
Copyright-paperwork-exempt: yes
* lisp/progmodes/cperl-mode.el (defconst): Add a word-start
assertion to cperl--single-attribute-rx
(cperl-after-sub-regexp): Dito
(cperl-init-faces): shorten matches of incomplete sub declarations
* lisp/progmodes/cc-langs.el
(c-get-state-before-change-functions)
(c-before-font-lock-functions): Separate the C and objc
versions, and add (to the first) c-unmark-<>-around-region and
c-before-change-check-<>-operators, (to the second)
c-unmark-<>-around-region and c-restore-<>-properties into the
objc versions of these lang variables.
These exceptions ("Invalid search bound (wrong side of point)")
were observed in test suite file class-24.m when moving point
up and down a line at a time.
* lisp/progmodes/cc-engine.el (c-forward-declarator): In the
c-syntactic-re-search-forward ~30 lines from the end of the
function amend the regexp for objc-mode such that "@end"
terminates the search, but "<" doesn't.
* lisp/progmodes/cc-fonts.el
(c-make-font-lock-search-function): supply a non-nil
CHECK-POINT argument to c-make-font-lock-search-form.
Perl 5.38 was released on 2023-07-03. This patch supports the new features
for 5.36 and 5.38 for font-lock, indentation, and imenu index creation.
* lisp/progmodes/cperl-mode.el (cperl-praise): Mention classes.
(defconst): Fix typo in docstring of cperl--single-attribute-rx.
Add "class" to cperl--package-rx, and adjust its docstring.
New rx sequence cperl--class-for-imenu-rx to capture classes,
use this in cperl--imenu-entries-rx.
Add "method" to cperl--sub-name-for-imenu-rx.
Add "class" to cperl--block-declaration-rx.
(cperl-sub-keywords): Add "method".
(cperl-mode): Add "ADJUST" to defun-prompt-regexp.
(cperl-after-block-p): Add new keywords for Perl 5.36 and 5.38.
(cperl-indent-exp): Add "field" to expression starters.

"package", because they also contain classes.
(cperl-init-faces): Add new keywords for Perl 5.36 and 5.38.
(cperl-find-tags): Add support for "class".

elements.

resource for fontification tests of class elements.
* test/lisp/progmodes/cperl-mode-resources/grammar.pl: Add some
classes to the test resource.
This helps clarify what each of these numbers mean. This is inspired
by 'compilation-mode-line-errors' which does the same.
* lisp/progmodes/flymake.el (flymake--mode-line-counter): Add
help-echo to mode line properties. (Bug#64424)
Fontifiy only macros at line beginning as keywords, otherwise as
variables. Add more accurate match for macros.
* lisp/progmodes/sh-script.el (sh-font-lock-keywords-var): Add
more accurate patterns for rpm macros. Also fontify parenthesized
word after keyword.
Going to the start of the first param and skipping non-word syntax
backward would seem to be the right thing to do, for traditional
C-style languages and also languages like Ocaml where function
signatures don't start the param list with '('.
