This includes symbols used for arithmetic functions such as -, /=,
etc. Using "-" or "/=" is still possible but doing so won't shadow
those functions.
* doc/lispref/symbols.texi (Shorthand, Exceptions): New
subsubsection.
* src/lread.c (read1): Exempt punctionation-only symbols from
oblookup_considering_shorthand.
* test/lisp/progmodes/elisp-mode-tests.el
(elisp-dont-shadow-punctuation-only-symbols): Tweak test.
The new name fits better in the family of variables that affect
the Lisp reader.

(elisp-shorthand-read-from-string): Use read-symbol-shorthands
* test/lisp/progmodes/elisp-mode-resources/simple-shorthand-test.el
Use new symbol name read-symbol-shorthands.
Only the shorthanded prefix is font-locked. This allows the remainder
of the font-lock logic to subsist (e.g. for macro-defining symbols).
* lisp/shorthands.el (cl-lib): Require it when compiling.
(elisp-shorthand-font-lock-face): New face.
(shorthands--mismatch-from-end): New helper.
(shorthands-font-lock-shorthands): New helper.

(xref-etags-apropos-location): Ditto.
Update all method definitions.
* test/lisp/progmodes/elisp-mode-tests.el (xref-elisp-test-run):
Avoid using 'oref'.
Instead of referencing obarray directly, that function has to consider
a collection of completions which includes the shorthand versions of
some of the symbols. That collection changes from buffer to buffer,
depending on the choice of elisp-shorthands.
To make this process efficient, and avoid needless recalculation of
the above collection, a new obarray-specific cache was invented. The
Elisp variable obarray-cache is immediately nullified if something
touches the obarray.
* lisp/progmodes/elisp-mode.el : New helper.
(elisp-completion-at-point): Use new helpers.
(elisp--completion-local-symbols)
(elisp--fboundp-considering-shorthands)
(elisp--bboundp-considering-shorthands): New helpers
* src/lread.c (intern_driver): Nullify Qobarray_cache.
(syms_of_lread): Add Qobarray_cache.
* test/lisp/progmodes/elisp-mode-tests.el
(elisp-shorthand-completion-at-point): New test.
* test/lisp/progmodes/elisp-resources/simple-shorthand-test.el
(f-test-complete-me): New fixture.
This simplification in requirements makes for more complex C code but
that code is much less wasteful in Lisp strings than the previous
implementation.
* src/lread.c (read1): Rework.
(Fintern): Rework.
(Fintern_soft): Rework.
(Funintern): Rework.
(oblookup_considering_shorthand): Rewrite.
* test/lisp/progmodes/elisp-mode-tests.el (elisp-shorthand-read-buffer)
(elisp-shorthand-read-from-string): Use new format of
elisp-shorthands.
* test/lisp/progmodes/elisp-resources/simple-shorthand-test.el (f-test)
(f-test2, f-test3): Use new form of elisp-shorthands.
It passes the tests designed for the previous Elisp implementation.
Likely, this isn't the final form of the implementation. For one, the
reader is much slower and allocates a Lisp string for every atom read,
regardless if its already interned or not. This has the potential to
be catastrophic in terms of GC.
Also rename the main variable to elisp-shorthands, from the
repetitive shorthand-shorthands.
For some reason, I had to put 'hack-elisp-shorthands' and
'load-with-shorthands-and-code-conversion', the new source-file
loading functions, in lisp/international/mule.el.
Otherwise, lisp/loadup.el wouldn't see them, for some reason that I
didn't investigate. This should probably be fixed.
* lisp/shorthand.el: Remove.
* test/lisp/shorthand-tests.el: Remove.
* src/lread.c:
(read1, Fintern, Fintern_soft, Funintern): Use
oblookup_considering_shorthand.

* test/lisp/progmodes/elisp-resources/simple-shorthand-test.el: New file
* lisp/loadup.el (load-source-file-function): Set to
load-with-shorthands-and-code-conversion.
* lisp/international/mule.el (hack-elisp-shorthands): Move here.
(load-with-shorthands-and-code-conversion): And here.
By putting delimiter syntax on the last character of Python
triple-quoted strings, this makes syntax-ppss be more accurate.
Previously:
emacs -Q something.py
type two single quotes
M-: (nth 3 (syntax-ppss))
notice how the return value says you're outside a string, correctly
type another quote
M-: (nth 3 (syntax-ppss))
notice how the return value says you're inside a string, correctly
backspace the quote just entered
M-: (nth 3 (syntax-ppss))
notice how the return value says you're inside a string, incorrectly
With this patch the last step is corrected. This helps things like
electric-pair-mode. Also, the test
python-syntax-after-python-backspace now passes, again.
* lisp/progmodes/python.el (python-syntax-stringify): Put
delimiter syntax in "inner" of the surrouding triple quotes.
* test/lisp/progmodes/python-tests.el
(python-syntax-after-python-backspace): Passes again.
In python-tests.el, the triple-quote pairing tests are passing
incorrectly, i.e. the auto-pairing functionality they purport to guard
isn't really working for users trying it interactively. Added a new
failing test, soon to be fixed.
In electric-tests.el, added tests for Python, too.
* test/lisp/electric-tests.el (define-electric-pair-test): Also run
main tests for python-mode. (pair-some-quotes-skip-others): Test
another slightly different pairing.
* test/lisp/progmodes/python-tests.el
(python-triple-double-quote-pairing): Rename from
python-triple-quote-pairing.
(python-triple-single-quote-pairing): New test.
To be able to filter results coming from
elisp-xref-find-def-functions, and for general ease of
understanding.
* lisp/progmodes/elisp-mode.el (elisp--xref-find-definitions):
Undo the previous change.
(xref-backend-apropos): Update accordingly.
(elisp--xref-filter-definitions): New function.
(xref-backend-definitions): Use it to post-filter the results
coming from elisp--xref-find-definitions.
* test/lisp/progmodes/elisp-mode-tests.el (find-defs-minor-defvar-c):
New test.
(find-defs-defun-defvar-el): Update test.

(cperl-init-faces, cperl-find-tags):
Replace ASCII regex literals by unicode-aware rx constructs.
(cperl-init-faces): Eliminate unused lexical `font-lock-anchored'.
(cperl-have-help-regexp, cperl-word-at-point-hard): Allow non-ASCII
word characters.
* test/lisp/progmodes/cperl-mode-tests.el

(cperl-test-unicode-proto, cperl-test-unicode-fhs)
(cperl-test-unicode-hashkeys, cperl-test-word-at-point):
New tests for unicode identifiers.
(cperl-test-imenu-index): Add a unicode identifier to the test.
* test/lisp/progmodes/cperl-mode-resources/grammar.pl: Add a
function with non-ASCII name for imenu tests.
This includes diagnostics for .h files that sprang up when checking a
c file. Those diagnostics are reported to the Flymake infrastructure
which does not (yet) do anything with them.
This includes a change to the test fixtures, too.
* lisp/progmodes/flymake-cc.el (flymake-cc--make-diagnostics): Rework
* test/lisp/progmodes/flymake-resources/another-problematic-file.c:
New file.
* test/lisp/progmodes/flymake-resources/some-problems.h:
Add a function declaration..

(xref--xref-file-name-display-is-abs)
(xref--xref-file-name-display-is-nondirectory)
(xref--xref-file-name-display-is-relative-to-project-root):
Update for the latest change in xref.el.
Improve the accuracy of `xref-find-definitions` by inferring the
likely namespace of the sought identifier from its context.
This reduces the number of irrelevant search hits when it is clear
what kind of identifier is being looked for (such as showing a
variable when the user looks for a function).
Co-written with Dmitry Gutov.
* lisp/progmodes/elisp-mode.el (elisp--xref-list-index)
(elisp--xref-infer-namespace, xref-backend-identifier-at-point): New.
(xref-backend-definitions): Use the buffer position for inferring.
(elisp--xref-find-definitions): Use the inferred namespace.
(xref-backend-apropos): Adapt call.
* test/lisp/progmodes/elisp-mode-tests.el (elisp-mode-test--with-buffer)
(elisp-mode-with-buffer, elisp-mode-infer-namespace): New tests.
* lisp/progmodes/ruby-mode.el (ruby-smie-rules): Align with the
first sibling on the previous line instead of the last (bug#32496).
That is, before it used to be
one.two.three
.four
and now it is
one.two.three
.four
Following advice by Mattias Engdegård, most uses of rx-to-string
were eliminated, and rx sequences used instead to define Perl
grammar components.
* lisp/progmodes/cperl-mode.el: (cperl-block-declaration-p): New
function, replaces regexp literals.
(cperl-imenu--function-name-regexp-perl): Deleted, use rx
sequences to find imenu entries instead.
(cperl-indent-line): Use rx components instead of regexp literals.
(cperl-sniff-for-indent): use `cperl-block-declaration-p' to
increase accuracy, use rx sequence for labels to replace
inaccurate regexp literals.
(cperl-block-p): Replace inline comment by docstring. Use
`cperl-block-declaration-p'.
(cperl-after-block-p): Use `cperl-block-declaration-p'.
(cperl-after-block-and-statement-beg): Replace inline comment by
docstring.
(cperl-imenu-package-keywords), (cperl-imenu-sub-keywords),
(cperl-imenu-pod-keywords) : New variables to sort imenu
entries into categories.
(cperl-imenu--create-perl-index): Use rx sequences to collect
imenu entries.
(cperl-init-faces): Use rx components instead of regexp literals
for labels.
* test/lisp/progmodes/cperl-mode-tests.el: Test rx sequences
instead of regexp strings
* lisp/progmodes/project.el (project--files-in-directory):
Pass "." as the DIR argument to 'find' because otherwise the ignore
expression can match the project root directory name, which we don't
want to happen (bug#50240). Fixup the resulting file names at the end
with concatenation.
Originally I thought it could lead to worse performance, but the
results show equal or slightly better timings.
* lisp/progmodes/xref.el (xref-matches-in-directory):
Apply a similar fix.
(xref--find-ignores-arguments): Use file-name-as-directory, so
that when passed "." replace-match still had the expected effect.
* test/lisp/progmodes/project-tests.el (project-ignores-bug-50240):
New test.
* test/lisp/progmodes/xref-tests.el
(xref-matches-in-directory-filters-with-ignores): New test.
* lisp/progmodes/cperl-mode.el (cperl-unwind-to-safe): Replace
(and extend) inline comment by a docstring. Handle edge cases when
inserting text with elisp (related to Bug#28962).
(cperl-process-here-doc): Add syntax-type `here-doc-start'.
(cperl-find-pods-heres): Make sure that the results of this
function are immediately visible.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-14343):
Add test cases for "empty" here-documents and inserting at the
edges of a here-document.
* test/lisp/progmodes/cperl-mode-tests.el (cperl--tests-heredoc-face):
New const.
(cperl-test-heredocs, cperl-test-bug-14343): Use it.
(cperl-test-identify-no-heredoc): Remove left-over message.
* lisp/progmodes/cperl-mode.el (cperl-mode): Use
`cperl-font-lock-syntactic-face-function'.
(cperl-commentify): Add a docstring, eliminate unused formal
parameter `noface'.
(cperl-is-here-doc-p): New function to detect whether "<<" starts
a here-document, factored out from `cperl-find-pods-heres'.
(cperl-here-doc-functions): New variable: List of functions which
allow here-documents as parameters, for use in
`cperl-is-here-doc-p'.
(cperl-process-here-doc): New function, factored out from
`cperl-find-pods-heres'. Fixed to keep correct fontification
after non-interactive (elisp) changes (Bug#14343, Bug#28962).
(cperl-find-pods-heres): Extend the doc-string to describe all
parameters. Don't remove text properties in recursive calls on
the same line. Call `cperl-process-here-doc' when appropriate.
(cperl-font-lock-syntactic-face-function): New function to
highlight c-style comments as here-documents (adapted from
perl-mode.el).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-identify-heredoc): New test for the new function
`cperl-is-here-doc-p'.
(cperl-test-identify-no-heredoc): New test for the new function
`cperl-is-here-doc-p', testing constructs which start with "<<"
but are no here-documents.
(cperl-test-here-doc-missing-end): New test to verify correct
detection of a missing here-document delimiter.
(cperl-test-bug-14343): New test to verify that inserting text
into a here-document with elisp does not break fontification.
* lisp/progmodes/perl-mode.el: Handle variables first to avoid
conflicting with keywords. This fixes cases like "$package"
(bug#49906).
Copyright-paperwork-exempt: yes
* lisp/progmodes/compile.el (compilation-error-properties):
When the end-column parameter of a compilation message rule
(in compilation-error-regexp-alist[-alist]) is a function, treat its
return value as if it were matched by the regexp, which is how it is
documented to work, and how all other parameters work.
The internal representation of columns uses half-open intervals but
don't expose that in the test cases, where we want to use the same
numbers as in the compilation messages.
* lisp/progmodes/perl-mode.el (perl-syntax-propertize-function):
Allow newline between a quote-like operator and its delimiter
(Bug#22355).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-22355):
Test case for the fix.
* test/lisp/progmodes/cperl-mode-resources/cperl-bug-22355.pl:
Test resource for a quote-like with newline before the delimiter.
* lisp/progmodes/perl-mode.el (perl-syntax-propertize-function):
Detect a quotelike operator immediately after a fat comma "=>"
(Bug#25098)
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-25098):
Test case for the bug with code from the bug report.

Add "|&" to the list of characters after which a slash starts a
regular expression (Bug#23992).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-ppss):
Correct the docstring.
(cperl-test-bug-23992): New test for Bug#23992.
(cperl-test-bug-42168): Adapt inline comments to the current code.
* test/lisp/progmodes/cperl-mode-resources/cperl-bug-23992.pl:
Resource file with example code from the bug report.
* lisp/progmodes/grep.el (grep-compute-defaults):
Add '-H' to grep-find-template (bug#48471).
* lisp/cedet/semantic/symref/grep.el (semantic-symref-perform-search):
Pass the root directory name without the trailing slash.

(project-root, project-ignores): New test project type.
(project-ignores): New unit test.

Add tests for good, bad, and ambiguous use of ? as regex
delimiter (bug#47598).
* test/lisp/progmodes/ruby-mode-tests.el (ruby-with-temp-file): New helper.
(ruby--set-encoding-when-ascii, ruby--set-encoding-when-utf8)
(ruby--set-encoding-when-latin-15): Tests for the previous commit (bug#48043).
