de3336051e Fix low-level handling of (big) C macros.
In particular, ensure that a comment detected by its syntax is not a CPP
construct marked with generic comment delimiter syntax-table text
properties.

* lisp/progmodes/cc-engine.el (c-beginning-of-macro, c-end-of-macro): Set
c-macro-cache-syntactic to nil when the cached macro changes.
(c-syntactic-end-of-macro, c-no-comment-end-of-macro)
(c-state-semi-pp-to-literal, c-state-full-pp-to-literal)
(c-state-pp-to-literal, c-parse-ps-state-to-cache)
(c-state-cache-non-literal-place, c-literal-limits, c-literal-start)
(c-determine-limit): When checking a parse syntax for a comment, check that
we're not in a CPP construct marked by syntax-table generic comment delimiter
text property.
(c-state-pp-to-literal): Change from a defsubst to a defun.

* lisp/progmodes/cc-mode.el (c-neutralize-syntax-in-and-mark-CPP): Check a
parse syntax as described above under cc-engine.el.

(c-invalidate-sws-region-before, c-invalidate-sws-region-after-del)
(c-invalidate-sws-region-after-ins): New variables and functions.
(c-invalidate-sws-region-after): Change from a defsubst to a defun.
Also pass
it the standard OLD-LEN argument.  Call both
c-invalidate-sws-region-after-{ins,del} to check for "dangerous" WS
cache
properties.

* lisp/progmodes/cc-langs.el (c-block-comment-ender-regexp): New language
variable.

* lisp/progmodes/cc-mode.el (c-before-change): Call
c-invalidate-sws-region-before.

c417f08b16 Correctly fontify C++ direct initializations with parens inside functions
Or, more clearly, when something looks like a function declaration and it's
inside a function, fontify it as a direct initialization.

For this purpose, introduce a "brace stack" for each buffer, where an entry on
the brace stack states how deeply nested a particular position is inside
braces inside a "top level", which includes classes and namespaces.

Also introduce a new "context", "top", with which c-font-lock-declarations
signals to c-forward-decl-or-cast-1 that point is at the top level.

* lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): add
c-truncate-bs-cache.
(c-flat-decl-block-kwds, c-brace-stack-thing-key, c-brace-stack-no-semi-key)
(c-type-decl-operator-prefix-key): new language constants/variables.

* lisp/progmodes/cc-engine.el (c-bs-interval, c-bs-cache, c-bs-cache-limit)
(c-bs-prev-pos, c-bs-prev-stack): New mostly local variables for the brace
stack cache.
(c-init-bs-cache, c-truncate-bs-cache, c-truncate-bs-cache, c-brace-stack-at)
(c-bs-at-toplevel-p): New functions which manipulate the brace stack (cache).
(c-find-decl-prefix-search): Keep track of whether we're at top level.
(c-find-decl-spots): New local variable cfd-top-level which records what it
says.  On calling cfd-fun, pass cfd-top-level as an additional argument.
(c-forward-declarator): Add new element DECORATED to the result list.  Set it
to non-nil when a match for c-type-decl-operator-prefix-key is found.
(c-forward-decl-or-cast-1): Handle the newly introduced context "top".
Introduce "CASE 9.5", which recognizes direct initializations.

* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare)
(c-font-lock-enum-tail, c-font-lock-cut-off-declarators)
(c-font-lock-enclosing-decls, c-simple-decl-matchers, c-basic-matchers-after):
Add appropriate `not-top' argument to calls to c-font-lock-declarators.
(c-font-lock-declarators): Additional parameter `not-top'.  Use not-top to
participate in the decision whether to fontify an identifier as a function or
a variable.
(c-font-lock-declarations): The internal lambda function takes an additional
argument `toplev' from c-find-decl-spots, which it uses in determining the
"context" of a declaration.  Add appropriate `not-top' argument to calls to
c-font-lock-declarators.
(c-font-lock-objc-methods): Add extra parameter to internal lambda function,
like for c-font-lock-declarators.

* lisp/progmodes/cc-mode.el (c-basic-common-init): Initialize the brace stack
cache.

a9118afcd7 Correctly analyze C++ list initialization in member init areas.
* lisp/progmodes/cc-engine.el (c-back-over-list-of-member-inits): Remove a
superfluous call to c-backward-syntactic-ws.
(c-looking-at-or-maybe-in-bracelist): Change calling convention, so that it
reports encountering the Java "new" keyword.  Add, as an alternative, a check
that we can move back over member initializations, and handle this as finding
a brace block.
(c-looking-at-special-brace-list, c-guess-continued-construct): Adapt to the
new calling convention of c-looking-at-or-maybe-in-bracelist.
(c-guess-basic-syntax, CASE 5A.3): Replace lots of inline ad-hoc code with
calls to c-backward-over-enum-header and c-looking-at-or-maybe-in-bracelist,
using the extra info from the value of that function to generate a
topmost-into-cont element where needed (in Java).

* lisp/progmodes/cc-fonts.el (c-font-lock-declarations): Adapt to the new
calling convention of c-looking-at-or-maybe-in-bracelist.

* lisp/progmodes/cc-mode.el (c-fl-decl-start): Adapt to the new calling
convention of c-looking-at-or-maybe-in-bracelist.

578d9aaf82 Adapt CC Mode for C++11 uniform initialization.
For fontification, introduce a new "context", 'non-decl, to be used for
brace
lists; also a new value for the property 'c-type, called 'c-not-decl.

* lisp/progmodes/cc-engine.el (c-back-over-compound-identifier): Check that
an ostensible symbol we're going to move over isn't a keyword.
(c-forward-decl-or-cast-1): CASE 1: Where we have two consecutive identifiers
(hence a declaration), and an unmatched open paren, perform
c-fdoc-shift-type-backwards to recognize the partial construct correctly.
Whilst checking a type decl expression, check for and handle C++11's "copy
initialization", where we have <type>(<constant>).  Recognize
<id><id>(... (where the paren is unclosed) as a declaration.
(c-looking-at-or-maybe-in-bracelist): New function, extracted from
c-inside-bracelist-p.  Recognize as bracelists "{"s which are preceded by
valid tokens other than "=".  Recognize a bracelist when preceded by a
template declaration.
(c-inside-bracelist-p): Call c-looking-at-or-maybe-in-bracelist in place of
much inline code.
(c-looking-at-inexpr-block): Amend so that it won't wrongly recognise an
initialization starting "({" as an in-expression block, by checking for
semicolons, as opposed to commas, separating elements inside it.
(c-guess-continued-construct): (CASE B-2): Recognize a brace-list-open by
calling c-looking-at-or-maybe-in-bracelist rather than checking for a
preceding "=".  (CASE B-5): New code to recognize new construct "return {
...}".
(c-guess-basic-syntax): (CASE 5A.3): Additionally recognize a "{" preceded by
"return", or "{" preceded by <type><identifier> as a bracelist.

* lisp/progmodes/cc-fonts.el (c-font-lock-declarations): Recognize brace
lists, giving them `context' 'non-decl.  Pass over elements of one by regexp
search for "," rather than calling c-forward-decl-or-cast-1.

* lisp/progmodes/cc-langs.el (c-return-kwds, c-return-key): New lang
constants/variables to recognize "return".
(c-pre-id-bracelist-key): New lang constant/variable to recognize tokens
which, when preceding an identifier followed by a brace, signify the brace as
a bracelist.

* lisp/progmodes/cc-mode.el (c-fl-decl-start): When searching outwards for
the start of a "local" declaration, move out from an enclosing brace when
that is the start of a brace list.

9cf9095838 CC Mode: check for and fix missing call to before_change_functions.
Fixes bug #24094 and bug #24074.

This can happen with `revert-buffer' or sometimes `find-file', when the file
is already in a buffer, but the file has been changed outside of Emacs.

* lisp/progmodes/cc-mode (c-after-change): When we detect a missing
invocation of c-before-change-functions, we assume the changed region is the
entire buffer, and call c-before-change explicitly before proceding.

a1db933c5b Amend CC Mode to handle big C++ raw strings correctly.
Problems were caused by such a string spanning jit-lock chunks, and by a flaw
in the +-500 bytes boundaries imposed for macros.

macro boundaries here.
(c-extend-font-lock-region-for-macros): Remove the check on the +-500 byte

a8231e00cb CC Mode now uses the new :after-hook feature of define-derived-mode
It now runs internal variable setting functions after the mode hooks, no
longer runs the mode hooks twice, and declares the configuration variables for
noise macros and macros with semicolons as safe variables (when given suitable
arguments).

Fixes bug #16759 and bug #23476.

* .dir-locals: Put the c-noise-macros-with-paren-names setting back into the C

c-make-noise-macro-regexps and c-make-macro-with-semi-re (where appropriate)
and c-update-modeline into the :after-hook form.  Remove the explicit settings
of the syntax table, the abbreviation table and the local key map, since they
duplicate forms generated by define-derived-mode.  Remove the explicit
invocation of each mode's mode hook, since they duplicate ones generated by
define-derived-mode.

ac16149ba4 Fix docstring quoting problems with ‘ '’
Problem reported by Artur Malabarba in:
http://lists.gnu.org/archive/html/emacs-devel/2015-11/msg01513.html
Most of these fixes are to documentation; many involve fixing
longstanding quoting glitches that are independent of the
recent substitute-command-keys changes.  The changes to code are:
* lisp/cedet/mode-local.el (mode-local-augment-function-help)
(describe-mode-local-overload):
Substitute docstrings before displaying them.
* lisp/emacs-lisp/cl-macs.el (cl--transform-lambda):
Quote the generated docstring for later substitution.

517505322a Merge some of the differences from the standalone CC-mode.
The main change is to only use the `category' text-property only when
available.  For that many calls are changed to use c-get-char-property,
c-next-single-property-change, c-sc-scan-lists,
c-sc-parse-partial-sexp, c-unmark-<->-as-paren.

(c-search-backward-char-property): Fix old min/max typo; probably
a copy/paste error.
(c-mark-<-as-paren, c-mark->-as-paren, c-unmark-<->-as-paren):
Turn them into macros that obey c-use-category.
(c-sc-scan-lists-no-category+1+1, c-sc-scan-lists-no-category+1-1)
(c-sc-scan-lists-no-category-1+1, c-sc-scan-lists-no-category-1-1)
