* lisp/progmodes/idlwave.el (idlwave-comment-indent-char):
Use a space since that is clearly what was meant.
?\ at the end of a line (ie, ?\LF) never was well-defined and produced
-1 most of the time, but will soon raise an error (bug#55738).
This doesn't matter much becaue this variable is unused.
(project-find-file): Use relative file name of the
currently visited file as an alternative default value.
(project-find-file-in, project-find-dir): Use 'file-name-history' (bug#55267).
* lisp/progmodes/flymake.el (flymake-mode-map)
(flymake-diagnostics-buffer-mode-map): Stop using
`defvar-keymap', since Flymake only requires Emacs 26.1.
* lisp/progmodes/which-func.el (which-func-unknown): Change string
displayed in mode-line from "???" to "n/a"; the former appears to
indicate an error whereas the latter is more indicative that the
current function is not known.
This is an amendment to the fix for bug #55230.
* lisp/progmodes/cc-defs.el: (c-with-string-fences): Add an edebug spec.
* lisp/progmodes/cc-cmds.el: (c-electric-pound, c-electric-brace)
(c-electric-slash, c-electric-star, c-electric-semi&comma, c-electric-colon)
(c-electric-lt-gt, c-electric-paren): Put the final
c--call-post-self-insert-hook-more-safely outside of the functions'
c-with-string-fences.
(c-electric-brace, c-electric-lt-gt, c-electric-paren): Put the calls to
electric-pair-post-self-insert-function outside of c-with-string-fences.
This fixes bug #55230.
* lisp/progmodes/cc-defs.el (c-string-fences-set-flag, c-with-string-fences):
New variable and macro.
* lisp/progmodes/cc-mode.el (c-called-from-text-property-change-p): Add
remove-text-properties to the list of accepted functions.
(c-clear-string-fences, c-restore-string-fences): Surround the functions'
innards with c-save-buffer-state to prevent text property changes causing
change functions to be called.
(c-before-change, c-after-change, c-font-lock-fontify-region): Replace the
explicit calls to c-restore-string-fences and c-clear-string-fences with
invocations of the new macro c-with-string-fences.
* lisp/progmodes/cc-awk.el (c-awk-extend-and-syntax-tablify-region)
(c-awk-end-of-defun)
* lisp/progmodes/cc-cmds.el (c-show-syntactic-information)
(c-electric-backspace, c-hungry-delete-backwards, c-electric-delete-forward)
(c-hungry-delete-forward, c-electric-pound, c-electric-brace)
(c-electric-slash, c-electric-star, c-electric-semi&comma, c-electric-colon)
(c-electric-lt-gt, c-electric-paren, c-beginning-of-defun, c-end-of-defun)
(c-display-defun-name, c-mark-function, c-beginning-of-statement)
(c-end-of-statement, c-indent-command, c-indent-exp, c-indent-defun)
(c-indent-line-or-region, c-fill-paragraph, c-indent-new-comment-line)
(c-context-line-break)
* lisp/progmodes/cc-guess.el (c-guess-region-no-install): These are all
"boundary" functions to CC Mode. Surround each by c-with-string-fences.
Python 3.10 introduced the "structural pattern matching" syntax, and
commit 139042eb86 told font-lock about the
new keywords. This adds them also as block-start statements, to enable
proper indentation of such blocks.
* lisp/progmodes/python.el (python-rx): Add "match" and "case" as
block-start keywords.
* test/lisp/progmodes/python-tests.el (python-indent-after-match-block,
python-indent-after-case-block): New tests to verify indentation of
"match" and "case" blocks (bug#55572).
* lisp/simple.el (escaped-string-quote): New variable.
(yank-in-context): New command.
(yank-in-context--transform): Helper function.
* lisp/progmodes/sh-script.el (sh-mode): Set up an
escaped-string-quote function.
* lisp/progmodes/sql.el (sql-mode): Define escaped-string-quote.
* lisp/progmodes/elisp-mode.el (elisp-completion-at-point): Don't
intern the string before point just to check whether we're looking
at `ignore-error' (bug#55491).
* lisp/progmodes/elisp-mode.el (elisp-flymake-byte-compile)
(elisp-flymake--batch-compile-for-flymake): Bind I/O encoding to
UTF-8, instead of relying on the locale's defaults. This is
needed because ELisp files use UTF-8 by default, but Flymake
doesn't know about that, since it isn't specific to ELisp.
* lisp/progmodes/cc-engine.el (c-append-lower-brace-pair-to-state-cache): Do
not record a position in a macro as the starting position in
c-state-brace-pair-desert. Instead record the position at the beginning of
that macro.
* doc/emacs/building.texi (Compilation Mode): Document it.
* lisp/progmodes/compile.el (compilation-hidden-output): New user
option.
(compilation-filter): Use it.
(compilation--hide-output): New function.
* lisp/progmodes/vhdl-mode.el (arch-alist, pack-alist)
(file-alist, unit-alist, rule-alist): Defvar them, since vhdl-aput
expects them to be dynamically bound. (Bug#55389)
(vhdl-speedbar-insert-hierarchy): Rename the PACK-ALIST argument
to PACKAGE-ALIST, to avoid shadowing the global variable.
