* lisp/progmodes/cperl-mode.el (cperl-find-pods-heres): Detect
the "<<>>" operator (Bug#42455).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-bug-45255): Verify that <<>> does not start a
HERE-doc.
* lisp/progmodes/cperl-mode.el (cperl-find-pods-heres): Add
"return" to the keywords which start a regex.
* lisp/progmodes/perl-mode.el (defconst): Add "return" to
'perl--syntax-exp-intro-keywords' (Bug#26850).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-28650):
New test (bug#26850).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl--run-test-cases): New macro, factored out from various
indentation / rewriting tests. Contains documentation of the
format used by the cperl-mode-resources files.
(cperl-test-bug-19709): Replace 'next-line' by 'forward-line'.
(cperl-test-indent-exp),
(cperl-test-indent-styles),
(cperl-test-bug-30393): Use the new macro.
(cperl-test-bug-19709): Make fit for Emacs 26.
(cperl-test-indent-styles): Skip for Perl mode (bug#44561).
* lisp/progmodes/cperl-mode.el (cperl-style-alist): Add
cperl-close-paren-offset to the settings for PBP style.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug19709):
New test to verify correct indentation of closing parentheses (Bug#19709).
* test/lisp/progmodes/cperl-mode-resources/cperl-bug-19709.pl:
New test case with code from the bug report.
* test/lisp/progmodes/cperl-mode-resources/cperl-indent-styles.pl:
Add a new test clause for cperl-close-paren-offset.
* lisp/progmodes/cperl-mode.el (cperl-mode): Add a fix
which is only required for Emacs versions older than 27.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug30393):
Add a test to verify correct indentation (bug#30393).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug37127):
Skip this test for older Emacsen. The bug has been fixed
in Emacs, but outside of CPerl mode, and therefore will not
be available for older versions via ELPA.
Don't call `syntax-propertize` from within narrowing
* lisp/progmodes/cperl-mode.el (cperl-forward-re): Revert last patch,
since it is now redundant.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug37127):
Remove unused var; fix test so it really catches the previous bug;
tweak the code to use mode-agnostic commands so it also works in `perl-mode`.
* lisp/progmodes/cperl-mode.el (cperl-forward-re): Suppress an
error message about "End of string/RE not found" when we are
at the end of a narrowed buffer where the end of a RE is
temporarily unavailable (Bug#37127).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug37127):
Add a test to verify that the message is suppressed when
inappropriate, but appears when the RE *is* incomplete.
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-mode-test-bug-10483): Increase the timeout to 2 seconds
and mark the test as expensive. Also, suppress it for Emacs
versions below 28, where the test times out though the function
works in manual tests. (Bug#44317)
* lisp/progmodes/cperl-mode.el: Delete a comment which explains a
bug which has been fixed a long time ago (bug#44073).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-mode-fontify-punct-vars): Add regression tests to verify
that fontification of punctuation variables doesn't start strings.
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-mode-test-indent-exp): Make sure that cperl-mode is active
for testing 'cperl-indent-exp', also skip this test under
perl-mode.
* test/lisp/progmodes/cperl-mode-resources/cperl-indent-exp.pl:
Eliminate dependency on unrelated customizable variables (bug#10483).
* lisp/progmodes/cperl-mode.el (cperl-style-alist)
(cperl-set-style): Add indentation style recommended by Damian Conway's
book "Perl Best Practices".
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-mode-test-indent-styles): Add a test to verify indentation
and unraveling of conditionals (bug#43457).
* lisp/progmodes/cperl-mode.el (cperl-indent-exp): Fix (Bug#10483)
Perl expressions (e.g. function calls) ending in ")" without
statement terminator on the same line no longer loop endlessly.
* lisp/progmodes/cperl-mode.el (cperl-forward-group-in-re): Make
sure that an error is reported back to the caller (Bug#16368).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-mode-test-bug-16368):
Tests for balanced (no error) and unbalanced (caught exception)
cases of `cperl-forward-group-in-re'.
* test/lisp/progmodes/cperl-mode-tests.el: Adjust for `perl-mode`.
(cperl-test-ppss): Rename from `cperl-test-face` and change return value.
(cperl-mode-test-bug-42168): Test the `syntax-ppss` state rather than
the font-lock faces, so it works for both `perl-mode` and `cperl-mode`.
* lisp/progmodes/cperl-mode.el (cperl-find-pods-heres):
Recognize {$a++ / $b} correctly as division. (Bug#42168)
* test/lisp/progmodes/cperl-mode-tests.el: New file with test
verifying the fix.
